A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Budget: $200 or less

There will be about 20-30 wireless devices using the router habitually.  I also work from home some days.  I currently have an Apple Airport, but was looking to replace it after the 5 years I've had it.  Apple doesn't make them anymore (I heard that somewhere) so was curious what others recommend nowadays.  I've used Netgear, DLink and Linksys in the past.  I'm down for whatever really.  I'll probably be purchasing it on Amazon unless Newegg or something else has a better price that you know of?

Thank you so much.

We have a motel with WRT54GL routers for wireless access running WDS.  The "hub" site router seems a bit flaky and is being rebooted fairly frequently - so it needs replacement.  Additionally, the owner wants to add another WDS spoke to cover a corner area with poor signal.

I figure there are a couple of options:

1) Buy a couple of old WRT54GL units to replace the hub and to add the spoke.  I've already tried a WRT54 v4 and it doesn't work with the others.  So, I suppose matching the models is pretty important.  Inexpensive to try....

2) Replace the existing 2 routers and add a 3rd with a newer router model.  I've done a bit of looking and I'm not much impressed by the lack of WDS information that I found.  I've had good luck with ASUS routers for WiFi but getting them to differentiate their routers re: WDS has proven to be difficult.

Any comments would be appreciated.  If #2, then which (newer) router would you bring into service?  These must have detachable antennas so we can connect to the existing antenna system.

(Yes, I know that Ethernet is best - but thanks for the thought!)

I am visiting a client tomorrow (50 WAPs, 5 Switches) to assist them in their wireless dropout issues.
They have cordless wireless phones which were on 2ghz, they upgraded it 5ghz, it didnt resolve the issue.
They have meraki switches and waps, and cisco asa.
Meraki waps they are using are MR 42;
https://meraki.cisco.com/products/wireless/mr42 

I have worked on Meraki SWs and WAPs but never had any issues with them.
Should i start with disabling SSIDs and enable one by one?
Which tools / apps i can install on my computer to diagnose an issue like this?
Thanks.

I am looking to develop an automation tool that can assist a NOC operation with WAN outage recovery without technician interaction. The automation tool will run in the lan environment (with no external access) and interact directly with the WAN interface. Please note this tool will not interact with any third party devices outside of the WAN environment. The test environment has Cisco Routers/Switches and uses Spectrum Monitoring.  Looking for suggestions on use cases and example event flow to develop on.

Hi Expert,

Need advise on how to configure mobile device to connect exchange LAB environment using my home router?

Currently i have setup the exchange lab, i'm able to access my exchange OWA using my mobile data through browser, but how can i test the mobile active sync?

I tried to export self signed cert from my exchange server and installed the cert into my iphone, but still couldn't receive email through outlook mobile apps.

Is it possible to be configure/test?

Thanks.

I am adding a Grandstream UCM6202 IP PBX on a network to use for an alarm notification system.  The network was previously closed and did not allow access to outside networks.  Alarm notifications were handled by an analog modem.  The updated alarm software is forcing me to install the IP PBX to allow
VOIP communications.  Full disclosure, I know absolutely nothing about VOIP technology.  I was given a box and a set of instructions.

My problem is that I need to identify the default gateway of the network, but none of the PC's on the network have it listed in the adapter settings.  The IP's are all static and the subnet mask is configured, but the gateway is not.  The IP PBX requires the gateway to allow communication with the outside world, so without that, I am dead in the water.  I thought that the gateway was usually the lowest numbered IP on the network, but in this case, it is not.  Is there a way to identify the default gateway without knowing where the router is physically located or the type of router it is?

I have (2) Watchguard M270's configured in a firecluster.

Interface 0 is the External interface configured with a /28 block.
Interface 1 is the LAN

We have consumed all of our IP's so I ordered another /28 block from our datacenter today. As soon as I configure Interface 2 for our new IP block, outbound traffic for the most part ceases to work on our network, however some things do work.. so we'll call it intermittent. As an example, I can ping out to 4.2.2.2 but can't ping 8.8.8.8. As soon as I disable Interface 2 that is configured for the new IP block, I am able to ping 8.8.8.8 again.

I'm assuming this is because we now have 2 WAN interfaces configured and outbound traffic doesn't know which interface it should be sending traffic out on but I couldn't be sure. I've made 4 calls to Watchguard support and nobody can identify the problem. I even had our datacenter issue us a different IP block just to rule out any kind of odd conflict but the problem persists with a new IP block.

Am I going about this all wrong trying to have 2 IP block's configured on our Watchguard? Is the better solution to just order a bigger block of IP's and re-IP everything? I was trying to avoid that hassle by just adding an additional block of IP addresses but it seems that what I'm trying to do here isn't working..

I would appreciate any advice or input that someone could give on this. Thank you!!

I am trying to buy Cisco router ISR4451-X-SEC/K9 with below specification. My question is can this router be configure for dual autonomous system (AS) in (BGP)? So, if one IP range blocked for some reason the second one will be available and the service not interrupted. If yes, is there any guide to do that?

I had a recruiter asking me if I had experience with Juniper routers and switches. I don't. But I do have quite a bit of experience with the Juniper SRX firewall. I wondered - is the "set..." syntax of the Juniper SRX firewall the same type of commands (or in some cases identical) to what used in Juniper routers and switches? Inquiring minds want to know.

Hi All,

This is one of those, 'I was asked a question, and I don't know the answer'.

A client has a double-NAT setup (good reasons), and is not on a fixed IP, but uses a dynamic DNS setup (NoIP but that shouldn't matter I think).

They asked if there is any downside to setting up the Dynamic DNS updates in both routers, rather than just the external one.

I cannot see any issues with this, but figured I would garner opinions here.

The external router is already doing the udpates, and working fine as it has been for some time.

The inner router can do it, and has a 'web' option to determine its actual external, routeable IP.  I have turned off the outer router updates, and activated the inner one, and it successfully and correctly updates the dynamic IP (I manually reset it to 1.1.1.1 in the NoIP web interface, then updated via the router and it changed back to the actual external IP).

I know I could just test it, but I don't want to do that, think it is all okay, leave, and get a call later that something is not working or causing a problem.

So, is there any issue with turning on both?  I'm not sure there is much upside either, but the question I have been asked is, why not turn both on?


Thanks,

Alan.

I am using Freepbx 14 and working fine but I got thousands of attacks and in Intrusion Detection, my public ip  has been blocked sometimes and because of this calls are not working. I am using fortigate firewall and opened the 5060 to 20000 ports for the FreePBX so My question is 1. are ports forward mandatory for inbound route ( if I change the sip registration port from 5060 to other and do same with the trunk provider ) . Please let me know how I can make this FreePBX more secure so call disturbance would not occurred in future.

Viptela in network have a lot router's function and also is used as edge router connected to ISP. It looks like Viptela has very similar function with regular router. And router such as ASR1K is used as edge router connected to ISP and it also has same function as Viptela. I wonder due to what function of Viptela we use Viptela instead of ASR1K? Thank you

I've just bought a DrayTek Vigor2620Ln (ADSL/VDSL router/firewall with backup WAN port and 4G LTE modem built in - UK version)

I want to be able to create a site-to-site (or LAN to LAN in DrayTek's terminology) VPN via an IPSec tunnel to a Netgear ProSafe firewall I have running at another site. Simultaneously I want to be able to access a L2TP VPN Server running on Windows 2012 RRAS (behind the DrayTek at primary site), via passthrough when I'm out and about.

Having created the site-to-site VPN with a few issues along the way, I have got it working. I have also got the L2TP VPN passthrough working so I can connect from my Windows laptop when away from the main network. HOWEVER, it seems impossible to get both working at the same time. For the site-to-site to work, I have to tick the 'Enable IPSec VPN Service' under the Remote Access Control settings on the Draytek. But once I do this, passthrough of the L2TP Windows VPN fails. If I untick, it is the other way around with the Site-to-site failing and the L2TP passthrough working.

I suspect someone out there will confirm DrayTek routers simply cannot both have a site to site and L2TP passthrough connection connected simultaneously (I momentarily achieved it once, on initial bootup). I appreciate both VPN types use IPSec, however every single Netgear and Linksys router I've owned and used to date has been able to do both simultaneously with zero problems. I'm hopeful I'm missing something, but fear I'm not and the …

I understand how to set multiple public static IPs to the WAN interface (usually eth0).  But I am in a unique/new situation (to me) on trying to figure out the following.

I am subscribing to a satellite service (no other viable option).  They offer "persistent IP's" which is ALMOST like public static IP's, I am being told (still discussing that with them).  The way they present it is:

a) Installation
b) Connect your device to the modem
c) Get an IP address
d) They manually map their DHCP address to the MAC address of your device in their table
e) Now you have a static IP (which is supposed to be routeable) - ie. Public

So, I am trying to figure out how in this scheme of things, I can statically map an email server behind NAT to this public IP.

Currently I have static mapping in my cisco T1 router where inside = outside, one to one mapping.

Moving off my older Cisco 1841 to the Edgerouter X for more functionality.

Thoughts on how to achieve that in the Edgerouter X?

Thanks.

Setup: PepLink Balance One router, using LogMeIn Hamachi for remote access VPN.
Goal: Replace LogMeIn Hamachi VPN with PepLink's built in Remote User Access.
Anyone has experience using PepLink's own Remote User Access, is it worth the while, secure?
Need detailed instructions please.

How to reset the password of admin user in Netgear Router?

I got Netgear Router whose admin password I have forgotten.  

The Netgear instruction says log in with ethernet cable to http://routerlogin.net/ with admin/password credentials.
I tried restarting the router bypassing off button for 30 seconds and waiting for 30 seconds and tried to log in again, still, it did not allow me to log in.

I discussed about Velocloud SDWAN w/ Aaron Tomosky in past and he provided a great deal of insights. This time my question is very brief:

Can VEP 4600 Device for Velocloud SWDAN accept a fiber handoff, our internet provider can only provide optical handoff.

Hi,

I have a client who needs a fast router/firewall as they will be hosting an App from their office.

This is a start up so money is tight, ensuring I put in a business grade router/firewall what is my best option for speed and security.

Thanks

Access-List a L2 Switch

I would like to know if we can apply ACL on L2 Cisco switch  based host IP address as well as on Host IP address + Port number.
An Example will be more helpful

Hello Experts,

Good day to you all!

I am not well versed with Cisco equipment but know a little bit with networking, that's why I decided to learn Packet Tracer. So, I was following a video online that simulates an internet connection configuration. I followed the video and recreate the Packet Tracer file and after I was done, everything was working. A workstation was able to access the simulated internet setup.

Now, I modified the setup from the example in the video to be a little bit close to what I have in the office. I added an ASA 5505 in between the Modem and Router 1841.

That's where my challenge started. I cannot for some reason, find out how make ASA work together with the rest of the set up.

I was hoping somebody here would be able to help what am I doing wrong.

I am also not sure what to attach or post here, to help you guys troubleshoot. I'm starting with a diagram and the configuration files of the ASA and Routers, and please let me know if there's anything else you need to help me out troubleshoot challenge i have.

Thank you in advance!

Regards,
BASTi

P.S. - I forgot to mention, I tried changing the type of cable connection from "straight-through" to "cross-over", between the modem and the ASA, and there's no difference.

One of our clients for whatever reason is not able to access their website from inside their network.
I tried whitelisting their domain on the router and their firewall.
 
I also created DNS forwarders on their server to point to their Website IP address.
I also put in a static DNS for google on one of the clients network settings. and still could not open up the website.

I'm running out of ideas!!
