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.

So if my understanding is correct from what I have managed to discover, the problem here is that any device connected to a cell phone hotspot, that has an active VPN, will simply route through the public ip connection on the hotspot and not go through the VPN.

Is there a way to 'route' through the VPN any device connected to the cell hotspot? I have heard that possibly rooting the cell phone may allow this, but I have never rooted a phone before.

Or, is there another way to make this happen? I am trying to create a secure VPN from our remote offices back to our main office using a cell phone...without having to step up to a LTE router.

On Demand Webinar: Networking for the Cloud Era

LVL 8

Ready to improve network connectivity? Watch this webinar to learn how SD-WANs and a one-click instant connect tool can boost provisions, deployment, and management of your cloud connection.

I have a Asus RT-N18U router. (but can buy another one), with DD-WRT firmware DD-WRT v3.0-r32170 std (06/01/17)
I want:
Hotspot for Restaurants that:
-People connect (no password) to WIFI
-they get a webpage (can be on router or in internet)
-webpage ask for emailadress
-once introduced emailadress and send it (to a server in internet with its MAC address) they get granted lets say 2 hours of internet
-after 2 hours they have to come back to the login page again (or better they get blocked for 10 hours with error webpage and after to login page again)
-no other service (not free and not payed) should be used

-the router mentioned offers dd-wrt with onboard radiusserver (I tried it and works), chillispot or nocatsplash (both I didn't get to work)
The router should be configured (WAN) as DHCP automatic conection and he should use his own network with his own DHCP server (so it is easy to connect him to an existing network)

I need somebody who configures the router and tell me how the configuration works. (where are modifyable files)

I have two locations with almost duplicate setups.
Location 1: On a network run by a PDC. The ISP is a cable company. The one office in this location has 3 computers all connected to the network via a Netgear 5 port switch. But also connected to this switch is a DSL connection via a dsl modem line to a preset location.. When the users need to connect to this dsl line they just click on the shortcut created on their desktop that directs them to the preset IP address. All other communication for everything else goes through the regular PDC/cable network. Using DHCP and automatically sees PDC as DNS provider. Works great.

Location 2; On a network but run just by a router, not a PDC, through the local Cable company. Two computers connected via an identical 5 port Netgear switch as in the location 1. They have the the exact same dsl line via the same dsl modem connecting to the same IP address as in location 1. The problem is that you can only connect to one or the other in location 2. If you want to connect to the dsl location via the dsl modem, you have to disconnect the cable from the router from cable company at the Netgear switch. Or if you want to use cable you need to disconnect dsl modem from switch. Also running DHCP and DNS being provided by either the DSL or cable depending on which you are using.

What would cause one to work and the almost identical one won't?

Which traffic will use the next hop in the PBR? The DENY traffic or PERMIT traffic under the ACL? I am pretty sure it means the PERMIT traffic will use the PBR but just want to double check

ip access-list extended PBR
 deny   ip 10.90.28.224 0.0.0.15 any
 deny   ip 10.0.0.0 0.255.255.255 10.0.0.0 0.255.255.255
 permit ip 10.0.0.0 0.255.255.255 any


route-map PBR permit 10
 match ip address PBR
 set ip next-hop 10.255.14.1

Hello Everybody ,

need you support RnS Expert Engineer

my scenario , the requirement are the router automatically move the the traffic flow based link delay by using PFR with active/ active by using Active/ Active ISP link utilization .

here are requirement and configuration

LAN subnet :-
188.117.100.172/29
188.117.124.36 /29
my goals to measure the traffic over all the available ISP
the primary path of the first subent is ISP 0A, primary path of the 2nd subnet is ISP02
if the any ISP link experiencing any delay the inbound and outbound shift the traffic automatically .

Hi Folks:

I am somewhat familiar with working with the Zyxel USG line of products, but have not done things like having multiple LAN segments, VLANS and setting bandwidth rules. I am setting up a ZyXEL USG40W for a client and need to accomplish the following:

Setup requirements:

1) Set up for Cable modem in bridged mode - This is DONE

2) Have separate LANs for computers and VOIP phones - Computers on LAN1 and VOIP phones on LAN2 (Have two separate unmanaged switches - (D-LINK) one for phones and one for the computers.

- I have done this by setting P2 to LAN 1 and P3 to LAN 2 under "Interface > Port Role" and then under "Interface >Ethernet" setting the IP Address for LAN2 to be 192.168.2.1 as opposed to 192.168.1.1 for LAN1. I assume this is the correct way to handle this issue. (Confirmation?)

3) Create bandwidth management rules to guarantee LAN2 a minimum amount of bandwidth over the WAN (in and out) - essentially anything on LAN2 is VOIP and needs QoS.

- not sure how to accomplish this. Should it be done by setting the Egress and Ingress bandwidths under the "Interface > Ethernet" settings for each of LAN (given that the VOIP phones and Computers are on separate unmanaged switches? Or do I still need to enable BWM and set rules?

4) Set up wireless so that devices connect on separate VLAN for purposes of possible bandwidth management - but possibly allow specific wireless users access to LAN1 for connection to the network server …

First, If I am correct:
Standard Access-list can match traffic based on Source IP address only
Extended Access-list can match traffic based on Source/Destination IP address , port number, protocol, etc...

well, there is also Named Access-list. We can have Standard Named Access-list and Extended Named Access-list
Is Standard Named Access-list similar to Standard Access-list, it can match traffic based on Source IP address only ?
Is Extended Named Access-list similar to Extended Access-list ,it can match traffic based on Source/Destination IP address , port number, protocol, etc. ?

Thank you

Experts,
We are using 6 classes of services w/ our network, ED, AF4, AF3. AF2 AF1 and DE. If DE is all full, but there is some room left in AFx class, can it is used by DE? Meaning can a lower priority can take over the higher priority Class? Please let me know.

Thanks

I am remodeling four homes. I have installed eight port structured wiring systems in all four. Each wall jack (room) includes one ethernet jack, one cable jack, and one phone jack. Everything is homerun to the utility room in the basement. Within the wiring cabinet located there, are punch down blocks and patch panels for all wires and cables. I would like to install in each cabinet, an eight port router or switch to include an integrated DHCP server, and POE jacks. One of these Jack's will be wired to a ceiling mounted Wi-Fi access point on the third floor in the center of the home. This device should be dual band AC 1200 or greater. Ultimately, the router or switch will be plugged into a cable modem providing Internet and telephone service. I am having trouble finding the router or switch, which needs to be small enough to fit inside the wiring panel. I also need an inexpensive access point device. The cable modem will be mounted by the cable service provider outside the panel. This arrangement will allow plug-and-play of any wired or wireless device in the home without the need for a PC based DHCP server arrangement. Has anyone done this? Any recommendations? I need to keep this reasonably inexpensive.

How to find the 1 and 2 and 15 th subnetworks of the address 192.168.1.0?

I have a remote client with an ASA 5200. They are going to get fiber, but for now are using their building's internet. The ASA config is below (edited for anonymity). It is able to ping the gateway (10.133.30.177), as well as 8.8.8.8 and other IPs. When attached to the 0/2 interface, a machine gets an IP in the 192.168.220.0/24 and can ping 192.168.220.1, but no further (not even 10.144.30.190). I've run "packet-tracer input inside icmp 192.168.220.102 8 0 8.8.8.8 detailed"

I need traffic from VLANS 3 and 4 to get to 5.5.5.5 via 2.2.2.2 and traffic from VLANS 1 and 5 to get to 5.5.5.5 via 7.7.7.2, using, I assume, policy based routing.
We’re using HP Procurve 56xx's for the routers.
I've tried using the PBR already, but I believe because the final step is to assign the Policy based route to a vlan, it's not working because the VLAN's aren't on the same router.
Any help would be appreciated!

Hi All,
We currently manage and maintain a SMB that consists of;

Main Site
---------------
-2x ADSL2+ Connections totaling approx 32Mbps download and 1.6Mbps Upload running through a client side network load balancer.
-Ethernet Smart Switches. No VLan. No Jumbo.
-HP ML350P Hyper-V consisting of 4 VMs. Domain Controller, Exchange, Files, RDS.
-Backup Physical DC server
-Currently we have rules in place to minimize the use of the primary ADSL connection from staff at the main site to keep the bandwidth available to staff who remote in via SSL gateway RDP.

3x Remote Sites
------------------------
-Each site has its own ADSL2+ connection with varying bandwidth from 16Mbps download and 0.8 Mbps Upload.
-Users connect remotely using SSL gateway RDP access.

Current Issues
----------------------
-Remote user experience is poor and impacted by staff internet use.
-Remote user experience can be impacted by users at the main site and remote sites internet access habits. Example. If a user downloads via web browser on the RDS this effects the available bandwidth for RDS remote connections. We have rules in place to prevent this but as per all router bandwidth rules these are best effort and only in place when 80% load is placed on the connection.

Suggested Changes
------------------------------
-Add a 10/10Mbps connection to the main site. (Only recently become available)
-Add a further ADSL2+ connection to any remote sites with more than 5 staff. This …

In the example below, which wildcard mask will cover the 4 subnets only
192.168.146.0
192.168.147.0
192.168.148.0
192.168.149.0

I though 0.0.7.255 is correct, but it will cover more than those 4 subnets.

Any wildcard mask calculator link, will be helpful.

Thanks

Hi all,

I am not a fan of Powerline devices, but sometimes I just have no other option then to use these device to get my signel to te area where it is needed. So therefor I would like to know which brand is best and what specifications to consider when making a certain choice.

I know it is best to use it on the same power group to get the best results. Therefor I often place an extra power outlet so that I work in the same power group. But I am wondering:

- Does brand make a difference
- Does speed make a difference in distance or stability (perhaps a 200MB goes further than a 1000MB)
- Do extension cords with adapters (i.e. a phone charger) have influence on speed and stability

And so on, so to sum up: how to get the best results with Powerline.

Thank you,

Which VLAN to enable ARP inspection

I would like to know which VLAN to enable ARP Inspection. Is it going to be on the same VLAN where the Trusted DHCP server resides on ?
Or on every VLAN in the network ?

Switch(config)#ip arp inspection vlan <VLAN Name>

I also wants to know about the DHCP Option 82 configuration.
Using IP helper-address <IP address> is enough or we need to add:
ip dhcp relay information option

Thank you

Hi, we are preparing the rules for Zone-based Policy Firewall on Router c3925, however we need to confirm which traffic usually pass through a router, so that the rule will not block/allow any useful/bad traffic. So can we have a method to see it?

Is there a way other than: "show ip cache flow", "sh ip traffic" ?

Many thanks in advance,
