Cisco VPN :: ASA 5500 / VPN Connection Looses Connectivity Even When Not Idle?
Mar 3, 2011
I recently started having trouble with my VPN clients loosing connection.I can create the conenction, work with it for a while, and then loose connectivity.Timing seems to be dependent on the activity over the connection.More activity, the conenction stops working sooner.
The cleint doesn't disconnect, I just can't access anything from the client.Disconnecting and reconnecting the client fixes the problem, temporarily depending on how much data I'm transferring.This works 90% of the time.The other 10% if I wait 30-45 minutes, and try again.. It works...with the same results...
It was originally isolated to a Win 2003 server that I was using as the client.It is now happening on my Win XP client as well.I'm using the AnyConnect client ver. 2.5.2014 with the VPN service on the UC520.Which I beleive, is similar to the ASA 5500 series VPN device.I am running ver 8.1.0 on the UC 520, and I can't remember if this started after upgrading to the new software.

I'm trying to configure ACS 5.2 so that should it loose connectivity to Active Directory it chooses the local authentication, however I can't seem to make this work.Within ACS 5.2, Access-Policies, Access Services, Default Device Admin, Identity,
I have a single rule configured for any device that matches tacacs to use the identity source of Active Directory,
If authentication failed: Reject
If user not found: Reject
If process failed: Drop
The ACS can not access Active Directory, when I debug TACACS authentication on any 65k or 2921 device I get "Received Authen status error".

Newly purchased DSC-930L connected to DIR-625. Firmware is 1.0 for DCS-930L and A1-1.09 for DIR-625.Camera works fine when connected with cable. Wireless enabled, fixed IP address.Unplug cable and camera still works fine for a while: can access the view page and view picture that does change. F5 refreshes page no problems. After a while (about 5 minutes) web page no longer reachable by browser. Reconnect cable and works fine, unplug and repeat the cycle same thing happens.Also tried: unplug ethernet cable, unplug power cable, wait 10 seconds, connect power cable, try to browse to camera - cannot reach camera.

I have an EA4500 router. It's the latest in a long line of Linksys routers I've owned and I'm pretty familiar with setting one up and making changes. But the EA4500 seems a bit more picky than previous routers. Last night I tried to enable port forwarding for ports 53, 80, and 88 for my xbox. I already had port 3074 forwarded. When I did that and applied the change, I lost all Internet connectivity. I tried cycling the power on the router with no luck. I finally got connected again by going to 192.168.1.1 and disabled those ports. The status page then said I had Internet connectivity but I really didn't at least right away. It took a couple minutes before I was actually able to to connect to the Internet again. What else should I check when it says I don't have internet connectivity?

My new RVS4000 (2.0.2.7) connects the WAN via PPoE with dynamic IP which is held at DynDNS and normally I see the RVS4000 via a router-to-router-VPN. That works fine so far, but every "some" days the router looses WAN connection (and with ist VPN). When this happens, last DynDNS-update is hours ago, so it didn`t reconnect. Looking on the routers site, the LAN is fully functional for clients that have got their DHCP-Information. New clients don`t get DHCP-Info (IP-address, DNS), both do not have internet access. The router`s WAN-summary shows, that it thinks to be "CONNECTED" but with empty WAN-IP and DNS entries. Klicking "DISCONNECT" and then "CONNECT" again solves the problem so far. The loss of connection is not the periodic break from the IPC, which is correctly identified and reconnected as configured. I wanted to trace the problem with the log, but there is also a bug. It stops logging at some time completely - neither email-log nor local log, so I never happend to be lucky to hit the point of loss of connection. Also the local log provides a first and next pages, but the next pages are always empty - not really useful.

I have a server (Windows Server 2003) that randomly looses connection with the default gateway and anything on the outside. When this happens, the server cant ping the gateway (A Juniper SSG5 firewall/router) and the gateway cant ping the server. But the server still can ping anything else on the network and everything inside the network works fine with it. The most reliable remedy is to reboot the router. Rebooting the server or resetting the network card sometimes works. I have tried both onboard network cards and a separate PCI network card on the server. There are no router log entries that correspond to the problem. This server is used as a Terminal Server for a remote office and as a file server.

Having an issue with my WLC 5500 and client connectivity. This just started today. Clients will connect for a short period of time and then drop off. WLC appears fine with the exception of a bunch of trap errors. I've rebooted the WLC but this did not clear the issue.

LAN connection gets disabled by itself on idle. Sometimes BSODs.A few days ago I tried connecting a MBlaze modem to my laptop (Windows 7 Ultimate 32 bit) to access internet. But it resulted in instant BSOD everytime.I deleted the modem software after that & didn't try to connect it again.But now, whenever I connect using my LAN broadband, connection works fine as long as I am continuously browsing something. But as soon as I stop browsing and it goes in idle mode in about 10-15 minutes, the connection gets disconnected. In the adapter properties, it shows that the driver is working properly. If I try to disable or uninstall it it doesn't give a response. The only solution to this is a forced shutdown & restart, after which it works fine untill not idle. I am not able to download anything because of this.I tried many things like reinstalling the network adapter driver, unchecking the power management feature, resetting the connection, etc. but nothing is working.

We are using the cisco sa540 router and shrew VPN to connect to our buiness network, mostly to connect to the workstations with RDP. Now we wonder if it posible that the connection will disconnect automaticly after an idle time of for example 30 minutes. And if so, how can i configure it?

Region : UnitedStates
Model : TL-WR1043ND
Hardware Version : V1
Firmware Version : 3.13.12 Build 120405 Rel.33996n
ISP : AT&T
Every 5 to 7 days my router loses connection with WAN (ISP modem) but connection over LAN is fine. It seems that 1043ND tries to connect to DSL modem from AT&T by username and password (that does not exists) instead of doing Dynamic IP. I understand that AT&T modem is of type of PPPoE but there is not a password or user id and connection must be dynamic. Page 192.168.0.1/logininfo of modem complains that I was trying to login with incorrect user id password. Every time I have to
1- connect the modem directly to my computer so the modem resets.
2- I have to reset 1043ND to factory default, reboot, and connect cables back how they were, Then go to WAN page do a release and renew to get connected to WAN again.

i have a WUSBF54G that will connect to my router just fine. Right when the device is first plugged in there aren't any problems. I can ping my router, I can ping google.com. The browsers all work correctly, etc. But after a while, maybe 30 minutes (it varies) I lose the connection to the internet. I can still ping the router. I can ping other devices on my network. But I cannot ping any websites by DNS name or by IP address and any browser I use won't display any websites. I have other wired and wireless connections on this network that don't have any problems. I even unplugged this adapter and plugged it into a different computer and had similar results. The device is relatively new (maybe a month old, but only used a few times within that month, and the use that it did get is mostly from trying to troubleshoot this issue.) Both computers I have installed the device on are running Windows 7 Ultimate. Both computers have the latest drivers installed from this site:

I have a netopia 3000 router and I have checked to see if the problem could be caused by this router but there is nothing out of the ordinary there. All of my troubleshooting has been using the Win 7 "network and sharing center" to connect. I couldn't get the linksys connection tool to work and actually, I noticed after reading this forum that the linksys wifi connection tool doesn't work with win 7 after all so I don't think using the built in win 7 wifi tools would cause the issue. Also, just to clarify, in an attempt to resolve the issue I have tried dynamically assigning an IP address for this connection and also a static IP address. Either method seemed to yield no results. It is a frustrating problem to say the least. I don't want to believe that the adaptor is faulty. As I said it is relatively new. Also, as I mentioned, when I first plug it in it will work correctly for about the first half hour or so before it will stop reaching the internet. I then have to physically unplug the device and plug it back in in order to correct the issue. I was thinking of creating some kind of script that will automatically disable the adapter every 30 minutes and then enable the adapter. I ran into another issue here though. If I disable the adaptor (either from device manager or from "Network Connections) the device will change status from "Not Connected" to "Disabled." So far so good. But then, when I go to enable the adaptor again the adaptor disappears from the list. It's as if it isn't plugged in any more. The only way to get it back is to physically unplug the device and physically plug it back in. How to "Enable" the device without it disappearing from the network adapter list.

I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.

Updated firmware was installed and settings were reviewed. Intermittently the E1500 looses its ability to connect only to our Android devices and "Cisco Connect" displays that it has lost Internet connectivity. The PC hard-wired to the E1500 and another PC connected wirelessly both work fine when this happens, despite the Cisco Connect message. The Android devices show the presence of the network, but they never "connect" - find the IP address. The problem can only be resolved by re-booting (powering off/on) the E1500. The loss of connectivity to our two Android devices and the Cisco Connect error display always are concurrent. E1500 looses connection to Android devices

Not sure where the best place to drop this question. It is a DIR-601 router. I have it configured in the virtual servers list as; internal system ip, public port/private port both 23, protocal tcp with inbound filter, allow all and schedule set to always. I have a second system with a different public port. I can connect to either one but after a short amount of idle time it appears to just drop the connection.

I upgraded my Linksys from 160n router to 4200V2 router. I configured 3 wireless Linksys webcams and they work fine. After 24hrs they i cannnot connect the via HTTP and webcames IP addresses disapear from the DHCP client table. If reboot the webcames the it works fine for next 24hrs. I did not make any modification to any settings and the setting looks just like i had on the 160N router

I've got an aol engineer visiting Thurs.to examine connection loss (since last Weds). But I'm convinced the problem is with the router. But from the tone of the aol tech questions I suspect he's already briefed his engineer to do his best to represent the problem as being either with my computer or positioning of router/filters/condition of wall-sockets - usual getouts.The talktalk router is neww, issued Feb 12, after my original router, speedtouch, started suffering idle timeouts every day.

We assign in our IPSec VPN the tunnel-address from our centralized dhcp server pools.In the profile we have two server's ip configured.In test (whireshark) we noticed that the discover always go to the first configured ip.
I do not understand and could not finf hints how the function is.
- backup server with a timeout when no answer comes from primary ?
- should ASA do simultaneous discover to all configured ip's ?
=>Problem is, that although the first server not answered in a timely manner, we noticed no discover to the second.
Here the partial CLI - Config:
++
tunnel-group AZInt07 type remote-access
tunnel-group AZInt07 general-attributes
authentication-server-group ActivPack
default-group-policy AZInt
dhcp-server 10.x.x.y
dhcp-server 10.x.y.y
[code].....

We have LMS 4.1 installed. After about 10 min of being idle, the browser becomes frozen, eventually crashing it. We applied this fix for lagging hoping it would fix the issue, however it has not. We have been tracking a problem internally where the Getting Started page hangs on login. The problem is with changes to Cisco.com access. We are actively working to get those fixed, but if this is what you're seeing the workaround is as follows:
a. Open the properties file name “gs.properties” under the path NMSROOT/MDC/tomcat/webapps/cwlms/WEB-INF/classes/com/cisco/nm/gs/ui
b. Update the field IS_DEFAULT_PAGE as “false”
c. Clear the browser cache and login-in(Daemon restart not required)

Something strange is happening to my Cisco 1941W. Every time I reboot the router i loose the running configuration of the service-module (Access Point module). The weird thing is that the router's configuration remain the same. I made sure i save the configuration by issuing the wr command on the service module console but still happens. My router's current IOS version is 15.0(1)M1 and my AP's is 12.4(21a)JA1.
I also did another test by making sure the startup-configuration was identical to the running configuration and when I reload the router still happens.

We had a lightning strike near the house and it fried my NIC card (or so I thought), also my power strip. I replace them both along with my Ethernet cables. My internet intermittently goes out, every couple of minutes. I keep getting pop ups saying "Local Are Connection has limited to no connectivity" and/or "a network cable is unplugged".

I have copied my computer's time in the router time setup under Time in the "tools" section of the router setup. After a few days of the router being up without a hard restart, it has lost 10 minutes somehow. I went to the logs and cleared them out and then looked at the entry showing that the log was cleared and looked at my computer clock and the time stamp of the log entry, and it was 10 minutes slower than my computer clock that I had originally set it from. I have a clock plugged in by the computer, and my computer always matches the clock that it plugged in, so I know it isn't my computer loosing time. What is going on here? Why does the router loose the correct time after it has been up and not unplugged or rebooted at all? I know that the router will loose the time if you unplug it, but this isn't the case here.

We have some 1242 LAPs in a two 5508 controller setup working fine. All LAP are configured to obtain address from DHCP. After first join we usually change some configs like HOSTNAME, AP GROUP, PRIMARY AND SECONDARY WLC. After a software restart or a complete power off/power on the LAPs joins the primary controller and all configuration still there. We now add a 1142 LAP and is does not retain the configuration after a power off/power on cycle, but after a software restart there is no problem. The only way to retain the config is setting the AP with a static IP address.
We use WLC 7.0.116 and we see no errors in the LAP console.

I'm trying to setup a router in my moms house. She has DSL and when the box is connected directly to her computer everything works fine. However, if I connect the router her computer reads "Limited or No Connectivity". I can connect to the router wired and wirelessly with my laptop, phone, and even her streaming media box without any problems. I ran IP config and i'm not geting a default gateway address.

I have a laptop that I usually use physically connected to my router, but sometimes I use it wirelessly when I want to lie down in bed.After using it wirelessly yesterday for about an hour,I brought it back to where I normally connect it with an ethernet cable but not I can't access the internet even with the ethernet cable plugged in! And wireless doesn't work either,I have "Limited or no Connectivity" for my LAN Connection and Wireless. I cannot afford a new computer (and I also doubt I need a new one).

I am working on development of a Windows based application which connects to a PDA like device over USB & communicates with it using RNDIS protocol. The device has a static IP in the APIPA range (169.254.2.1). When it is connected to PC, Windows allocates a dynamic APIPA IP (169.254.x.x) to the RNDIS adapter. I have confirmed that there is proper connectivity with the device (I can ping it, can access a web server on the device etc.).But the problem is that after Windows allocates the dynamic IP, a 'limited or no network connectivity' message is displayed in system tray.
Since the device & software will go out in the market, display of this message (& exclamation mark on the network tray icon) is undesirable. I know that it can be suppressed by setting property of network adapter, but would prefer a solution that would not require end users to do any settings using APIPA addresses is essential as we would like to avoid conflicts with end users' LAN addresses.
