View 2 RepliesI have an ASA 5520 for my firewall. (ver 8.0(4))I have an external hyperlink that works from dsl at home but not from behind my corperate firewall.When I filter my real-time log viewer for this destination address I see the build up and immediate teardown of the session.The log indicates the teardown was initiated from inside.The informational alerts are
Built outbound TCP connection 726440542 for outside:201.116.168.172/6666 to inside:172.16.x.x/3586 (65.204.x.x/52001)
Teardown TCP connection 726440542 for outside:201.116.168.172/6666 to inside:172.16.x.x/3586 duration 0:00:00 bytes 77 TCP Reset-I
Reset-I means that something (the firewall or my pc which is the source) is telling the firewall to end the session.
I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.
I've got a remote site which is connected to the headquarters via VPN site to site IP Sec tunnel. When I am in my office I have no problem to reach the remote network, but, when I try to connect to the remote network via VPN client, I can't reach it.in the remote office I've hot a Router 3800 (Cisco IOS Software, 3800 Software (C3845-DVENTERPRISEK9-M), Version 12.4(13c), RELEASE SOFTWARE (fc2)) in the headquarters I've got an ASA 5520 Version 8.0(3) I've chequed access-list, and network objects and it seems everythink ok.

Per PCI & company policy all VPN users have a 12 hour session limit. They will disconnected after 12 hours regardless of use. Is there any way to send a message prior to the 12 hour limit to warn the users that they will be disconnected in x minutes? I'm running SSL VPN on a ASA 5520 ver 8.4(1)
View 1 Replies View RelatedI have a problem on a Cisco ASA5520 version 8.2(5). A customer has set up a syslog to keep tracks of tcp sessions made by vpn users. On the syslog we filter %ASA-6-302013 and %ASA-6-302014 log messages, respectively: Built inbound TCP connection and Teardown TCP connection. When the connection is made by a vpn user, at the end of the log line you see the vpn username which should be the same in both the messages for the same connection. I have verified that when a user, let's say UserA, disconnects from the vpn, their tcp sessions are not properly closed; if another user, let's say UserB, establish a VPN immeditaely after and gets the same IP address previously assigned to UserA, the log sessions are recored with UserA in the %ASA-6-302013 message and UserB in the %ASA-6-302014 message. I presume this is due to the fact the tcp sessions are not tore down when the first user disconnects and it looks like a bug to me but I didn't find it referenced anywhere. Is there a way to have all tcp session tore down when a user disconnects the VPN connection?
View 2 Replies View Relatedi have user connected to office using Cisco vpn client , Cisco asa 5520 acts as vpn gateway, frequently the users got disconnected from the server while the VPN still established and not disconnected!
what is the cause of the issue , where the fault is located ? how to start the troubleshooting to figure out the issue?
I recently faced an issue at work. Clients want to make ipsec site-to-site vpn redundant. I have 2-asa-5520 working in a stack. Is it possible to configure site-to-site vpn in a redundant mode, like first peer ip address is x.x.x.x and secondary is y.y.y.y (backup) ?
View 1 Replies View RelatedHere's the current scenario:
[LAN] <---> ASA 5520 <---> Cisco 2911 <---> [Internet] <---> Server A
|
|
[DMZ]
Whenever I access a website running in "server A" (only HTTP traffic) everything works fine. The problem is that when I try to access a different service on the same server but listening on port 2000/tcp I get the TCP Reset-O message on the ASA and the workstation's browser says that "Internet Explorer cannot display the webpage".
A weird thing: if I access this service from a machine on the DMZ, it works fine. From the LAN (Inside) it does not work. The main difference is that from the LAN to OUTSIDE the ASA does NAT. From the DMZ to OUTSIDE it's just routed. I did another test from the LAN and the captured traffic is attached. I've been messing around with protocol inspects and firewall + NAT rules on the ASA but no luck at all.
I've been tracking a conversation on my firewall. I have an inside device that is trying to communicate to a server outside to send data. The conversation is suppose to be all 443. I see that there is a TCP connection made and a dynamic NAT that translates my inside device to the public IP, and appears to change the port to 65415. The problem I'm having is that the conversation ends with reset-O, and I'm wondering if that port has something to do with it, or if it's just that their server is resetting the connection because of an issue they are having? The vendor says no firewall rules are needed for this device to communicate with their server.

View 5 Replies View RelatedI have Any Connect (ver 3.1.01065) configured on Cisco router 891. VPN is working fine from the desktop, but I also need the ability to establish a VPN connection through a RDP connection (i.e. I'm using RDP to connect to a PC which has AnyConnect installed on, then trying to establish a VPN connection). OS Windows 7 SP1 x86.I've read about changing some settings in profile file (changed the <WindowsVPNEstablishment> option to "AllowRemoteUsers". Then applied the profile to the relevant Group Policy. Connected VPN from the PC (not through RDP), so that it downloads the new profile, and then disconnected again.): url...
But this make sense to the cisco asa... I have a cisco router on the ios 15.1. I've checked the XML file on the local PC to confirm the profile has been downloaded and is has, and I can't see the AllowRemoteUsers option.So I still can't start VPN through an RDP connection. (Error is "VPN establishment capability from a remote desktop is disabled. A VPN connection will not be established".)This also happened with the previous version of AnyConnect (2.5.xxxx).The PC's local routing tables look fine, and I can't see any conflicts that would cause the RDP session to drop.In the main window of Cisco anyconnect secure mobility client Ive noticed label: Web Authentication required.

View 1 Replies View RelatedI have configured my Cisco 881 and finally got past the "Cannot see my network" with IPSec VPN issue.I have a usecase where I need to access the gateway from the VPN Session.When I connect to the VPN using Cisco VPN Client 4.8x, I do not get back a Default Gateway on the VPN Adapter. When I try to ping my LAN Gateway IP (10.20.30.1) it does not respond and I cannot access it with any other tools.I am pretty sure this is a very ACL issue and it makes sense to hide the gateway by default but the big question is how do I configure my router to see the Gateway and be able to access it from the VPN session?

What command sequence disconnects you from a TS session? My setup is as followsr1 > TS > 2009-2621XM 2010-3825-R1 2011-3825-R2I can connect from the TS to any of the devices. The issue is that I am telnet'd to r1 and from there telnet'd to the TS. So when I type "Crtl+Shft+6, x" I go directly back to r1 and not the TS. Furthermore if I resume the session on r1 the TS is still connected to whatever session I was in prior to disconnecting. I've experimented with the disconnect and escape characters but I'm at a loss what it is that changes this.
