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.

Hey everyone, I am wrapping up my configuration of my MSR2004 router. The only thing I cant figure out is how to change the routes. Every syntax I use seems to not work, and if I go through the web gui>Network>Static Routing (or Routing Table) I just get the circle of death... Mainly I am just concerned with the 0.0.0.0 and routes to the vlan-interface's

This is what I need to configure it for:
0.0.0.0      0.0.0.0      Static      60      216.85.201.237      Ethernet0/1
127.0.0.0      255.0.0.0      Direct      0      127.0.0.1      InLoopBack0
127.0.0.1      255.255.255.255      Direct      0      127.0.0.1      InLoopBack0
172.16.0.0      255.255.0.0      Direct      0      172.16.60.30      Vlan-interface4
172.16.60.30      255.255.255.255      Direct      0      127.0.0.1      InLoopBack0
174.47.139.0      255.255.255.192      Direct      0      174.47.139.1      Vlan-interface1
174.47.139.1      255.255.255.255      Direct      0      127.0.0.1      InLoopBack0
216.85.201.236      255.255.255.252      Direct      0      216.85.201.238      Ethernet0/1
216.85.201.238      255.255.255.255      Direct      0      127.0.0.1      InLoopBack0
216.85.207.0      255.255.255.240      Direct      0      216.85.207.1      Vlan-interface2
216.85.207.1      255.255.255.255      Direct      0      127.0.0.1      InLoopBack0

Dear wizards, my router was hang this afternoon. Internet for email system was interrupted for about 20 mins. we could not telnet or connect to it via console port, and had to reset the router to bring it back.

so how can we know what happened? where can we find the logs? was it a signal of DDoS attack? and if so, how can we mitigate it?

I have a Synology NAS Server with a 500gb Hard drive connected and a Nvidia shield TV box/console.
Both the devices have the PMS (Plex Media Server) installed.

What I want to do is watch IPTV through plex. Ideally I would like to have the IPTV installed on the PMS that is on my Synology NAS Server as that is on and running all the time,  so that I can watch IPTV on my android phone when out of the house.

Does anyone know where to manually find the plugin folder on the Synology NAS Server or if not on there then where the plugin folder is on the Nvidia shield TV?

Also, can anyone recommend a stable IPTV channel for plex which I can use to load the IPTV playlist m3u?

Thank you...

I have a Cisco 1811 that won't boot due to a memory issue.  It has a 64MB compactflash card in it.  Does that card have the running config?  I don't believe I have a backup of the config anywhere.

I have a FVS318N where I have setup multiple vlans to the best of my knowledge correctly.  The clients are receiving DHCP leases on the different subnets however they cannot communicate with each other.  I have checked the box labeled "inter-vlan routing" on each of the vlans however traffic does not seem to be properly routing. Any ideas?

I a private school's IT services.  They have three campuses in three different towns however all three have very similar infrastructure.  They have the same SonicWall NSA2600, Dell Enterprise Switches, and separate VLANs for Faculty, Students, Guest and Security cameras.  

The issue that I am having is when a classroom is assigned a project or task the requires the entire class to use their computers to access a single resource on the Internet.  I have a few examples with this but it doesn't seem to matter what the website is.  The first ten or so students to request the website will be able to resolve the web address and load the web page.  The remainder will end up with a connection timeout error trying to load the page.  And if those 10 or so who did load the page, if they hit refresh will get the same error as the rest.  If there is a break in the request to the page for about a minute it will load again.

They have a website hosted by GoDaddy and I have even contacted them to see if we were triggering any alarms or peaking any resources and they confirmed that we are not nor would they expect us to be with the account we have selected with them.  The error on the web browser "Connection Timeout Error"also does not coincide with  what would be witnessed had it been some kind of flood protection with them.

I have contacted SonicWall support and we have recreated the scenario at all three schools and review configurations on all three SonicWall devices to rule out …

I am currently setting up a training room where I want everything to be automated. I have door style windows on a slanted roof that currently needs to be opened manually. The problem is that the windows are very high, and it is not practical to try and open them manually.

They are side hung escape windows with wooden frames and dimensions 660x1180mm.

I want to convert the windows so they can open automatically, preferably using a remote or voice commands using my SmartThings hub or Amazon Alexa. Would this be possible?

Would you be able to guide me to the type of window opener/actuator that would best suit my window and what else I would need to get to be able to use my SmartThings hub or IFTTT event triggering.

Any solutions would be much appreciated.

Robbie

All experts, I have remote site with multiple vlans connected by site to site VPN.  there ip address range start 10.0.8.0 / 255.255.252.0 and some of department has 10.0.28.0, 10.0.29.0, 10.0.30.0 / 255.255.255.0.   How do i combine these networks and route them by simple route statement use on vpn?  I currently set to all vlan networks mapped and working but I would like to have simple statement such as following

10.0.0.0 255.255.0.0 to  10.0.28.0, 10.0.29.0, 10.0.30.0 / 255.255.255.0 and 10.0.8.0 / 255.255.252.0

Devices:
Google Home,
Aruba IAP-305 (RW)
NordVPN


I am trying to set up a VPN for my Google Home so it will register as being in the US. I am currently in Ireland and have purchased a subscription to NordVPN.  From what I understand, a VPN cannot be put on the actual Google Home device.

I currently make a lot of calls to the US. Google Home offers free calls in the US but is not available here in Ireland. This is one of the main things I want to get from my Google Home.

If the net result of the VPN makes Google Home look like its in the US, I do not want the rest of my tech devices to think they are in that location, i.e all of my other tech devices have locations in Ireland.

Robbie

Finding for the tools which will support the device management in the IOT/M2M.
The tool capability expectation is to monitor and manage all device types including switches,routers(manly MPLS 4G Router) and gateways in telecom, Smart Home hubs, sensors and appliances M2M devices, smart power and water metering devices, health care devices and more.
Kindly let me know any such tools available in the market.

hi folks

i am wondering if anyone ever used Cisco WRVS4400N's port mirroring feature to monitor traffic of a given port?

i have tried any individual port or even all ports together as the source, but i still cannot see any mirrored traffic from listening to the specific port (Port 4), as shown below.

Screen-Shot-2017-09-13-at-13.29.04.png
i have no idea why the device doesn't work as expected. do you have any suggestion please?

regards,

I had a new Actiontec router installed on August 29 and since then my computer freezes every ten minutes for one minute. You can set your clock by it. After a number of hours with tech support who have no idea I have looked at a number of things. I had the installation tech back. His computer does not freeze. We patched mine through an ethernet cord -- it runs fine. It appears to have something to do with my wifi adaptor. I have a realtec 802.11 card. What I found in looking at the device board is that a series of WANmini ports installed at the same time as my router. Could they be the problem? Do I need them? Can they just be removed or do they need possibly to be replaced?

I activate NAT on ADSL Port and add a port redirection for smtp service to internal mail server address.
I add two firewall rules to allow traffic from anyone on the redirection port to the mail server and vice versa.

if i made a telnet on port 25 to the external ip address of the router (fix IP) i get no connection.
Even more if i monitor the system via dime tools on debug level i see no incomming traffic.

What may be wrong?  

On another line i have a Bintec R3000 Router configured in the same way and this is working very well.

Helpful to verify reports of your own downtime, or to double check a downed website you are trying to access.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

Hello,

We use an RDP session through a VPN tunnel to connect to our hosted software out of state.

We constantly experience latency through all of our VPN tunnels.  I can run a constant ping from our hosted provider back to our environment to get a small picture how bad the response times of the pings are.

The ping times will be consistent for a little while hovering at 55ms - 67ms and then we will see "request timed out" multiple times and then ping times will rise.  It seems like the ping times fluctuate a lot  (I assume they would as the signal is traveling through multiple possible connections).

When ping times are at 55ms or less everything seems fine.  However, when it goes up from their end users report latency.

We are not hard lined to our ISP as everything is wireless.  Our internet pipe should be sufficient at all locations as we have spoken with our ISP and we do not hit the high water mark on our bandwidth - only rare spikes the main site.  

We are not hitting the high water mark on bandwidth usage at any of our other sites.  Is there a good piece of Enterprise level software that one could use to help get a clearer picture of where the issue occurs?

What kind of architectural questions should we be presenting to our ISP?   To our hosted provider?

1.  Is your VPN Server over-utilized?

Hello;

Am facing an issue where my Cisco ASR 1002-X keeps rebooting itself at random time. When i run the show version, i can see the reason for reload is: critical process fault, fman_fp_image, fp_0_0, rc=139

On my syslog server, i keep getting this error: %IOSXE-3-PLATFORM: SIP0: cpp_cp: QFP:0.0 Thread:171 TS:00000041045846946120 %IPSEC-3-HMAC_ERROR: IPSec SA receives HMAC error,

 I dont know if that could be the reason of my router reload or if it's an IOS bug, am running asr1002x-universalk9.03.16.04b.S.155-3.S4b-ext.SPA.bin.

 
Your help will be highly appreciated.

Hi,

Any chance someone come accross PBR and acess list conflict on 1841/1941 router configuration.

We have access list to allow specific IP addresses on 1 subnet browse Internet.

For some (1 specific at the moment we've created Policy Based Routing to route all it's traffic via different gateway on another router.

It's only working if I do not have allow Internet access list applied to that LAN interface.

Hoping for some ideas.

Thanks

We have (2) DAP-2553 DLink access points installed at opposite ends of a very large building.  Both have the same SSID, Security Settings, Password, etc.

Our laptops connect easily to our network via either one of these access points.  However, as the laptop moves and begins to lose it's signal from one of these access points, I would expect the other access point to provide seamless auto-connectivity to the device.  Instead the device simply drops its connection.

Am I missing something in the initial configuration of the access point?

DLink tech support has been terrible.  Their solution is for me to purchase 2 new access points along with a controller.  This would be a last resort due to expense.

Please advise.

I need to change a company's WIFI password.  They are using the Ubiquiti Unifi.  I am not the one who set it up, nor is the company who set it up still around.

When I run the Discover program, it locates the device, showing a particular user name and password.  When I click "manage" I get "The device is already managed.  Please reset the device to factory before perform L3 operation."

All I want to do is change the wifi password.  Seems inexplicably difficult, or complicated.  Anyone have experience with this device?

for example check the nodes about flapping,down , restarting reasons etc
