Cisco VPN :: ASA 5510 - Client Connections Getting Dropped

Mar 30, 2011

I have some remote locations that connect to my ASA 5510 cluster (Aktive/Passive) using the Cisco VPN Client, from which the connection gets disconnected at random intervals (could be 5 minutes, but sometimes after 15 minutes). However, some other remote locations do not have this problem. All locations have the same VPN client configuration (distrubited by pcf file).

I already disabled isakmp keepalive on the ASA but this did not work. If I read it correctly, the Cisco vpn client logging shows that the ASA initiates the ending of the connection.

Cisco VPN :: IPSec Client Connection Through ASA 5510?

Mar 28, 2013

I've got random connection issue when I try to connect to a VPN gateway through an ASA 5510 (IPSEC client ->ASA 5510->VPN Gateway).
 
When the tunnel is coming up, those two lines appears in the captured traffic on the internal interface :
 
<private internal IP>.500          > <destination IP>.500:  udp 541
<public external IP>.500 > <destination IP>.500:  udp 541
 
When it's not coming up, the port nuimber for the public IP is not 500
 
(private internal IP).500  >  (destination IP).500:  udp 541
(public external IP).442 >  (destination IP).500:  udp 541
 
I don't understand why sometimes the port for the public external IP is 500 and sometimes not.

I have configured anyconnect for phone at ASA 5510. Phone can connect to Corporate network through VPN from outside without any problem.

Dec 5, 2012

Our Cisco ASA 5510 running 8.4(4)1 just started dropping packets and our AnyConnect clients are seeing horrible performance.  The system is extremely slow compared to just a couple days ago.Nothing has changed on the system.  I can post the configs if needed.

I have done a "sho vpn-sessiondb detail svc" and I can see the dropped packets of the individual users, but cannot see why the packets are still dropping.how I can correct this and restore speeds?

Dropped Internet Connection After 5-10 Minutes?

Feb 23, 2011

I have a Dell Latitude d810 laptop that has XP Professional and an Intel PRO/Wireless 2200BG driver. It has been working fine for nearly 3 years. Recently I changed it from a domain to a workgroup and now the internet connection drops after about 5 - 10 minutes.When I say "drops", I am referring to the browser can no longer display the webpage. The internet connection still shows to be "Excellent". I even tried pinging www.google.com and it can still ping the website but the browser just stops working. I have tried Firefox and IE.I updated the DNS to use the default primary DNS suffix. The only way to get the browser to re-establish a connection is by rebooting the laptop.[CODE]

Cisco Firewall :: ASA 5520 - ESMTP Connection Dropped

May 30, 2013

We are working with an ASA 5520 and it seems there is an issue with some email messages sent throught it. When there are many recipients in the emails the email messages are not sent, and I have revised the server an the only thing I see is connecting dropped. When I went to see ASA log and see this log report: ESMTP Classification: Dropped connection for ESMTP Request from 'interface': servername/portnumber to outside: IP address/25; matched Class 2: cmd RCPT count gt 100 tcp flow from interface:servername/portnumber to outside: IP address/25 terminated by inspection engine, reason - inspector disconnected, dropped packet. So I think there should be an inspection of ESMTP packets and if they detect an email message sent to over 100 addresses, then the packet is dropped, am I right? if so, what should I do to let those email messages be sent?

IBM Desktop / Network Connection Dropped Several Times A Day

May 20, 2011

The computer in question is one of 30 computers in the same office that is not currently experiencing this same thing. All connected though the same switch, patch panel, etc. Testing has proven that the switch and line is fine.We have a server set up for all of the multifunction printers on property and we simply map the printers through this unit.We have an exchange server for email.File server... for... files. Okay, here is the situation. This IBM desktop will be connected to everything, able to print, email, connect to files, etc etc.Then, or so it seem, will just lose its connection. no email printing etc. She is asked to put in her network credentials again. and usually this works. (it seems that the network dropping out may take up to 3 minuets to fully restore and she tries to put in her credentials too soon).After each event she is able to restart her computer or type in her credentials and get back to work.. after mapping the printer again.

Sonicwall Router - Every 1 Minute The TCP Connection Is Dropped?

Sep 1, 2011

we got a Sonicwall router and we have been having stability issues. Every 1 minute the TCP connectio is dropped as well as UDP packets. This router is connected to a T1 connection and its requesting a DHCP lease every couple minutes as well. We originally had two WAN connections, and we have disabled the second one because someone thought it was that, but obviously it has to do with the internal network. This is a dual WAN router.

ISP - Comcast Cable Internet Modem model SMCD3GNV wired/wireless combo (2 pcs connected 1 wired 1 wireless)When the connection is online, the speeds are fine- the issue is the 2-3 times a day when the connection drops off. The error that we are getting is "cannot connect with primary dns server" however in our attempts to restore the connection we have: [code] is there some issues in the area that we are not aware of? being that the signal levels are within range what do you think the problem resides in? FYI, both connections, the wired and wireless connections both have connectivity issues equally.

Windows Vista - Wireless Connection Dropped Frequently?

Mar 21, 2012

My computer is one that I built with windows vista, and for the wireless connection I am using a USB adaptor. I am not too sure what other info I need to put here.My connection used to drop frequently (around every 5 min) and I would have really slow speeds (10ish kb/s). Recently, for some unknown reason, the dropping has stopped, but now I am getting speeds of around 9-15 kb/s.

The thing that has me COMPLETELY stumped is when I plug my laptop into the router, the wireless speed on my PC speeds up to, according to speedtest.net, 5.8 Mbps. If I unplug the laptop from the router,the speed on my PC slows down to .25 Mbps, yes - POINT .25 Mbps.I have attached the tester .

D-Link DIR-655 :: Internet Connection Being Dropped And Random Reboots

Mar 30, 2011

I've been having a number of issues with performance on my DIR-655 with streaming media, internet connection being dropped and random reboots. Over the last couple of weeks it has been getting worse, to the point where I'm about to act out the printer scene from Office Space but with my DIR-655!  It has been rebooting, completely killing WiFi networks and Internet Connection, almost every 20 minutes when I'm watching DivX over the network. The relevent information about my network is as follows:

-Hardware:
-D-Link DIR-655
-Hardware Version: A3 (US) , Firmware Version: 1.34NA

As an experiment I reconfigured the DSL-380T into PPPOE mode and set the DIR-655 into DHCP Client.  This was over 2 hrs ago.  So far - no random reboots, no jittering on the Media Center Extender playing videos, no internet drop outs..It seems to me that the DIR-655 doesn't cope well when it has to do the PPPOE network protocol as well as the routing, WiFi and other basic functionality that it should be able to cope with.I'll leave it running as it now is and report back later, but from the dramatic change in behavior I'm hoping that I've finally cracked my perf issues with the DIR-655.

Dell :: Latitude E6510 - DW1520 / Wireless Connection Being Dropped All The Time?

Oct 28, 2012

I have a Dell Latitude E6510 with a DW1520 Wireless-N WLAN half-mini card.  I used to have a D-Link router which broke down so I purchased a new router which is a Linksys E2500.  I changed the configuration on my laptop to use WPA instead of WEP.  My router is configured with fixed channels (not auto).  My internet connection is continuously being dropped and I have to re-logon to everything (very annoying with vpn tunnels).  All my other desktops/laptops in the house work without problems.

D-Link DIR-601 :: Website Filter / Access Control Causes Dropped Connection For Non-blocked Sites

May 4, 2011

I'm trying to set up a website filter on my DIR-601.  I created a policy for 2 MAC addresses, with a schedule from 10AM-6PM, selected "Block some websites", and disabled logging.  Under website filter, I added some entries, and selected "DENY computers access to ONLY these sites".  When the policy is enabled, and I try to access one of the blocked websites, it gets blocked correctly ("The URL access was denied by administrator.")  However, for all other websites, I get "server unexpectedly dropped the connection" errors, eg "Safari can�t open the page [URL] because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again." or in Chrome "No data received.  Unable to load the webpage because the server sent no data."  This happens with ALL non-blocked websites.   I'm using hardware version A1, firmware version 1.01NA.

Linksys Wireless Router :: E4200 Connection Speed Dropped From 2megs / Sec To 100k / Sec

Jul 1, 2011

I got several issues with the E4200.First of all, my connection speed dropped from 2megs/sec to 100k/sec with that router. Flashing it with the lastest firmware worked but still, I don't get all my speed as I has with my WPG54GS (with DD-WRT).Second, speed is really unstable, like if it was working by burst of data.Third, I got a gigabit port on my computer, plugged in the router and still, I can't make more than 10megs/sec WIRED (!) between my computers. I desactivate the ipv6 from my network card but still, no luck.

Linksys Cable / DSL :: WAG160N Modem Just Dropped Wireless Connection Constantly In Various Time Period

Sep 28, 2012

I've bought a "WAG160N v1.0 Annex A" almost 2 years ago. I never used it's wireless feature untill we moved our house. Now it's like 4 month I'm using its wifi feature and I've got to admit I'm really frustrated by its functionality!
 
For months the modem just dropped wireless connection constantly in various time periods. Somtimes it went like 2 days without any problem but some other times I had to change channel every 15 minutes for it to get back working. And yes it didn't get fix until I changed the channel, otherwise clients had to wait several hours for a 50/50 chance of reconnection. Now It's two days the changing channel trick no longer works. I tried all channels and even put my notebook next to the modem but no luck. The notebook sometimes connnects to the access point but disconnects after a few seconds. Somtimes it doesnt even detect the SSID of my WAG160N modem. Some friends suggested that the wireless hardware of my modem is broken and no longer works but I'm eager to know if it is broken why is it still broadcasting and sending signal.
 
I've tried everything from upgrading and downgrading firmware to turning on and off the modem several times and changes modem position. And even tried the G-only 20MHz mode.We are at a very crowdy place. Using inSSIDer I could pick about 15 other access points. Only few of them are using Wireless-N, most of them are using Wireless-G.This is the inSSIDer diagram of my WAG160N modem from a client: [code]

Cisco VPN :: Can't Ping Anything From Client - ASA 5510

Nov 15, 2011

I have a VPN client running on a laptop connected a DSL circuit. The VPN client is configured correctly for an external address on another firewall, this external firewall passes through ISAKMP / IPSEC to an ASA where it terminates. The client authenticates and gets an address from the client pool (VPNCLIENTS – 10.2.16.x / 24) and the tunnel completes with no problems. From the internal ASA I can ping any internal network behind the 10.0.3.240 interface (INSIDE) and I have a route on the inside network to get to the 10.2.16/0 clients to point to this address (10.0.3.240). All good so far.
 
Now the problems begin. I cant ping anything from the VPN clients (10.2.16.0) network to anywhere, I cant ping any interface on the ASA or any internal network. I also cant ping the client from the ASA and therefore not from the internal network either. This configuration is bare bones configuration so I don’t even have the NAT exception rules added. Network diagram attached too.
 
interface Ethernet0/0
