Cisco WAN :: SR520-ADSL-K9 - Can't Even Connect To Router After Power Failures
Aug 6, 2012
I'am a bit newbie at using Cisco products and here is my problem : I have set up a VPN tunnel between 2 Sites (A and B) a few month ago using 2 cisco SR520-ADSL-K9. All was working fine until power failures occured on the sites B (secondary site).
What happened was that none of the ethernet ports were working, excepting during booting, I was then able to ping computers linked to ports Fastethernet0, FastEthernet1, FastEthernet2 and FastEthernet3 but after a few seconds all ports were disabled but my DSL seemed to be working.
So I took back the router home to check it. I managed (I think) to make a factory reset using a serial terminal and following the procedure described here [URL]
Since I did the reset, I thought I would be able to re-use Cisco Configuration Assistant (3.1) to re-configure the router (I am very bad at using the command lines) but I am unable to connect to the router using the supposed default IP : 92.168.75.1 (I set my computer to use 192.168.75.50 IP adress with mask 255.255.255.0). But I can't connect to the router ... even if the Ethernet ports seem to work because green light is on when plugging my cable. connect to my router using CCA ?
For more information, here is what I get when I run "show startup-config" and "show running-config" in terminal console. I guess the objective is to make the startup-config beeing the running-config, but I have no idea on how to do that ..
show startup-config
show running-config
Router#show startup-config

We've (an independent school) just bought an SR520 with a view to replacing one of our Draytek 2820s. We need to set up some site-to-site VPN with NAT and the Drayteks won't do it.
I've been trying to configure the SR520 in just the most basic fashion using CCA (3.1) and the CLI but with no success. I can't get a PPP connection with our ISP.
I've tried following the instructions in the software config pdf and also tried replicating the various 'running configs' reported in other posts in this forum to allow connection to a UK ISP, with no success. I don't know how many times I've reset the poor thing to factory defaults.
I have to say that I'm dismayed at how flaky the CCA appears to be. Many of the things I've tried with it simply don't work and often end up in it hanging. Close to useless in my view.
So instead I've tried to use the CLI which seems a lot more solid but is somewhat impenetrable and there's precious little by way of supporting explanation.

we have cisco sr520 adsl router at one of the sites. A device is connected to the LAN and needs to be communicated directly to the server with 3rd party over internet. we have a static public IP( a.b.c.d) for cisco router and want this IP redirected to the LAN IP address(192.168.1.20) of the device but locked to only 2 inbound IP address (eg.-1.2.3.4 , 5.6.7.8) .

I got myself lately Cisco SR520 router with some basic firewall functions built in. This is going to be used for my home broadband, so no need to be really super secure, as it would be for some business. I managed to configure it, however there are few things on the firewall side, which I don't understand.
This router had some default configuration in it's flash, when I bought it. There are class maps.... how it works or how to add/edit rules. Also, do I need to use class maps, or can they be replaced by ACL's to certain extend? How to add/edit class maps rules to allow certain port (eg. 3333). Pease see below part of the default config:
class-map type inspect match-any SDM-Voice-permit
match protocol sip
class-map type inspect match-any sdm-cls-icmp-access
match protocol icmp
match protocol tcp

I have a SR520W-ADSL-K9, I´m trying to setup it trough CCA, but I have some troubles. At the internet connection I mark PPoE option, enter the vci=0, vpi=35, the username, the password (like the ISP TELMEX suggest), and mark the IP Negotiated option, but I have not find the ISP service give me an IP Address and establish the connection.

I leave on one of my computers on all the time, an Acer desktop with Windows XP. I also have two laptops. I have Verizon DSL and a linksy wireless G router. When we have a power outage the Acer desk top loses it's internet connection. Trying to reconnect the connection takes hours. Even when we finally get it back we have no idea how we did it. The laptops which of course were off have no problem.

C3745-ENTSERVICESK9-M version 12.4(10b). ROM version 12.2(8r)T2.This router appears to be generating spurious fan failure alarms. The fan assembly has been changed for a new one, the engineer checked and was satisfied that in a physical functional sense the replacement fan assembly was definitely working, but we now have all 4 fans showing as failed. We are being told that the replacement unit is believed to be part of a batch of faulty fan assemblies and that it was a known Cisco issue.

I made a custom-built V1 Windows Home Server that I really would like to be able to remote access. I have tried the Netgear 3700, but it did not allow remote access. A D-Link DIR-825 does, but it, and many D-Link products, have a persistent problem of requiring a reset due to dropped connections. I have had 2 of the DIR-825's drop connections. I have been told that their QoS components cannot handle the load on them and fail, causing the drops, but I cannot corroborate that.Perhaps what I need is a router that allows "NAT loopback"? This way I can see the WHS Console verify that I can access the server from outside my network. I have tried to do so with the above routers via a 3G connection on my iPhone 4 and all except the D-Link failed to allow access to my WHS.
I should add that I am using a D-Link DSL-520B modem on ATT DSL. It is a 6MB connection from the ISP. Previously the modem was in "bridge mode" on the D-Link router. Also, contacting ATT I was told they do not block any ports. I have tried forwarding the proper ports (80, 443, 4125) for the WHS, but that has not given me remote access. I did get them by enabling UPnP on the D-Link. Is all this an issue of needing the modem on "bridge mode" in order to work properly? Any router for my needs that allows remote access (NAT loopback needed?) and also has a solid connection? Gigabit ethernet is a must have too. Otherwise I am open to options. I would like a combined router/modem unit to make things a little easier.

I have been trying to connect a new Cisco 887VA Router to the Internet using ADSL via PPPoE and have been unsuccessful. The DSL line is active and functioning correctly since the current "old" router is connected and working without any problems (the "old" DLink router is connected to an Alcatel DSL Modem). AT&T provides the ADSL service to the office. When the Cisco Router is connected it tries to negotiate a connection via PPPoE on the WAN interface but utlimately fails. The IP for the WAN interface is dynamic.
Below is the current configuration of the router.

In each case, the routers have functioned flawlessly for a period of 2 to 8 months, then suddenly begin to require daily to hourly reboots to keep the speed up, and often times fail to respond to any web activity whatsoever. Ping tests are intermittent, sometimes failing but other times succeeding while web sites remain unresponsiveFor three years I lived with two or more room mates at a time, each of us with our own computer (or 2) and all doing a lot of peer to peer downloading. I realize a router can overheat during heavy use like this, so buying new routers so regularly has seemed vaguely understandable. However it doesn't seem like that is the case in my most recent failure.I've lived alone for the past 3 months, and have owned the Belkin Play Max N600 HD since. I have NOT been P2P downloading or putting a heavy load on my router in any way (or so it seems). Yet as of about two weeks ago, it has suffered a major slowdown just like all of its predecessors. Yet my 30 mbps internet connection roars to life the moment I plug the modem directly into a computer.
My desktop remains on 24/7 but like I said before, I do not do constantdownloading/uploading. Both wired and wireless connections are effected equally, and I have always kept all my routers WPA encrypted.When websites become unresponsive on my Belkin today, it is usually after everything has been sitting idle for some time (overnight, or all day while I am at work). Speaking of work, today is a perfect exampleI remoted into my home desktop and was able to interact just fine, yet when I would launch a browser and try to load any website at all, I get absolutely nothing. I had to transfer a text document through DropBox (which also still worked) because I couldn't get Google Docs (or gmail) to load on the remote computer

I have one ADSL router that I have configured Port Forwarding on it, but the internet is very slow. I also have another 3G router and I want to use it for internet because it is much faster, but it cannot do Port Forwarding. How can I connect this two routers in one network such that ADSL router is for Port Forwarding only and 3G router is for internet only?

I have a Embarq 660 Series modem, but i wanted wifi. so i bought a belkin N300 wireless router this morning. And it won't connect to internet. I'm sure i've plug the cable in the right spot. And the EQ 660R ADSL router/modem is working. The belkin package came with a CD, and it's the setup program for the wireless router. but as it tried to form a connection, it said failed to connect to the modem. so does this means embarq 660 series isn't compatible with Belkin N300?

I bought my dad a Netgear N150 DGN1000 Wireless ADSL Router to replace his D-link router which kept dropping the wireless signal. I have established a wired connection and my ipad, iphone and his old laptop connect wirelessy to it without any problems but I just cannot work out why his laptop won't connect to the internet.It recognises the wireless signal and it says its connected and that the signal is excellent but when I try to go on the web or check emails it just won't work.I've tried deleting all his wireless networks and starting from scratch but don't know what else to tryHis PC is running windows Vista

Two of us were using power line adapters to connect to the router. We had no problems whatsoever. Then my other friend got a power line adapter and starte connecting that way too. Then pretty much both mine and his stopped working. Yet my other friend can still use his no problem.I ran and ipconfig /all and I'm noticing that its not giving me a default gateway address. I tried inputting it manually and still nothing. My windows 7 pc keeps saying it can't identify the network.I also have this problem when I try connecting my Xbox and he has the same issues with his ps3.Yet we can both connect wirelessly with no problems.The router in question is a Netgear N300+.

We had a power outage the other day, and now the wireless router cannot connect to the internet. Network Magic shows there is no connection from the device to the internet. I tried repairing it through Network Magic but it wasn't able to fix it.
My PC is directly connected to the wireless device by LAN cable. If I connect the PC directly to my DSL router I can connect to the internet, but not if I connect to the wireless router and from there to my DSL router. I tried resetting the wireless router to factory defaults and then going to [URL] and resetting up the router security settings. But Network Magic still shows the bad internet connection.
I then tried resetting the router to factory defaults again and installing it from scratch using the setup CD but that failed as well. I'm not at home right now so can't remember exactly at which point it was but I think it was either when the setup wizard tried to detect the device or install the device.This is the second time I've had to reset up my router due to power outage. Last time I was able to get it working by doing the first steps above.

I have an E1200 and if a device - such as my tablet or laptop - is left unused for a period of time - say for 4 or 5 hours - they won't reconnect to the router unless I do a power cycle/reset on the router.

My netbook keeps getting DNS Lookup Failure messages. This happens about every 20 minutes, give or take, though sometimes it can go longer before the failure. I can "solve" the problem by quickly repairing the network connection, but that's tedious. It happens only on my laptop and not on my housemate's desktop (wired connection) though he did say that it happens to him on his laptop as well. In looking around I thought the problem might be because i'm using Chrome, but it happens on Firefox and Opera as well.

I have over 20 units doing the same thing and it seems to be a software isssue but i dont see any bugs or posts on it. This is only on 2960S switches and not 2960 or 2960G units.
If i use the password reset feature to break the units into rom and then type "boot" instead of power cycling the unit, they will fail MBIST post tests. If the unit is power cycled or left to boot normally on its own, there is no issues and all post tests pass. I know MBIST is Memory Built In Self Test and was thinking maybe breaking the unit into rom disrupts those memory tests for some reason. I tried the following software and got the same results with all of the images:
122-55.SE2
122-55.SE
122-53.SE2
122-53.SE1
Logs attached are from the same switch, one with password reset procedure used and while left to boot on its own.

I have a site to site ipsec tunnel setup between an ASA5510 and a 2951 Router. The ASA 5510 is on a 10.x subnet with a few vlans behind it. There are also 7 other ASA5505 that connect to this box with ipsec.
The 2951 is on a 10.x subnet with multiple vlans behind it (10.x and 192.x subnets).
When I had ACL to allow traffic from 10.20.0.0 (ASA) to 192.168.111.0 (2951 - voice vlan) the connection comes online and is stable.
The minute I add any of the following, the connection drops off with Phase 2 errors: 10.20.0.0 to 10.1.200.0 10.20.1.0 to 10.1.1.0
I can add a second 10.20.0.0 to 192.168.10.0 with no problem at all. The issue only seems to occur when attempting to add traffic from 10 to 10 on the tunnel.

I manage a VPN 300 concentrator which has been happily working for several years without any problems. All users are part of the same group and authenticate to an RSA server. We recently moved from RSA authentication manager 6.1 to RSA authentication manager 7.1. Everthing continued working fine for several weeks, then at the beginning of this week we started getting users intermittently failing to connect to the VPN. I'm not sure if this problem relates to our new RSA server, but we have other network devices which authenticate to it with no problem so I guess the problem is with the VPN concentrator itself.
When users fail they just get a generic "Reason 427 connection terminated by peer" error message. The live event log shows "group = vpn, status = Not-in-service" when their connection fails. Other times they connect normally and no error messages are displayed. There seems to be no real pattern, sometimes your connection fails but if you keep trying you will eventually get in [however it can take many attempts over an hour or two before you succeed, or you may get in straight away with no problem].
I dont believe its a network problem, as I have run continuous pings to the concentrator and the RSA server whilst users are experiencing these problems and there are no drops.
The RSA servers authentication monitor always shows that the user has successfully authenticated, whether the users connection actually succeeds or not. I am tempted to just reboot the concentrator, but we have site-to-site VPN tunnels connected off it and I'm a little concerned that if it is faulty it may not come back up at all.
