Cisco VPN :: 1841 / VPN Site-to-site With Zone Based Firewall

Jan 28, 2013

The problem I am having is very strange and I have tried to upgrade the IOS on the 1841 to solve the problem but no luck.  The issue is when I enable Zone Based firewall security on of the 1841 routers two VPN site-to-site tunnels stops working.  If I turn off CEF (no ip cef) then the traffic for both tunnels works.  Someone told me that the Zone Based firewall must have a match for the VPN traffic and I created that with ACL 160 and 161 but it did not solve the problem.
Current IOS is below.

Cisco VPN :: 1841 / 1811 - Site To Site VPN Is Up But No Traffic Gets Through?

Jul 28, 2012

Using the Cisco Configuration Professional software I have created a site to site VPN connection (between a cisco 1841 and 1811).The tunnel appears to be up as far as the routers are concerned, but I am unable to ping anything on the remote networks. I thought route maps may have had something to do with this but I cant see what is worng with them.Just so you know, the 1841 device already has a functioning VPN tunnel to another site. The peers I am concerned about are 141.0.59.x and 109.238.78.x.

Cisco VPN :: Is ICMP Required For Site-to-site VPN 1841

Jul 24, 2012

I am in the process of setting up a site to site VPN connection with a Cisco 1841 with the AIM-VPN-SSL-1 module and an NEC IX2015. We are using a GRE tunnel with IPSec.The problem we are having is the NEC router will not repsond to ICMP packets (and there isn't a way to make it respond). Will this cause any problems with the tunnel?

Cisco VPN :: 1841 / Site To Site Vpn Not Working?

Apr 24, 2012

i have 2 routers both 1841's and am trying to get a simple static vpn up and running. Now One router is at our main location (ill call it router a) and the remote location (ill call it router b). Both have internet connectivity that works, can ping router a from b and b to a. Now on router b side when i run show crypto isakmp sa on router b i get the following:
SBOneonta#show crypto isakmp sa
dst             src             state          conn-id status    MM_NO_STATE          0 ACTIVE (deleted)    MM_NO_STATE          0 ACTIVE (deleted)    MM_NO_STATE          0 ACTIVE (deleted)

i72.43.229.138 is the router and the other ip is i have no idea! its no where in the config, but that shows me this router is trying to do something. Now on router a when i run the same command i get this:
show crypto isakmp sa
dst             src             state          conn-id slot status
a whole lot of nothing! now i have been working on this for a few days now and i cant understand why i cant get this simple vpn tunnel to work! I have debuging on both routers, router a shows nothing period for vpn traffic, router b shows a connection from the which again i have no idea who or where this ip is and its not in the config any where.

Cisco VPN :: Site To Site And Remote VPN Possible With 1841?

Oct 18, 2011

I have an 1841 that I set up to do site to site VPN between my company's network and an external network.  This has a backup connection point.  All works well including automatically failing over to the backup site.
We also want to be able to VPN remotely to our company's network using the same 1841.I have tried many different ways to configure this, but the best I had resulted in an external VPN request taking down the site-to-site link.
Is this possible? Our internet connection is through an ADSL router set up with pasthrough, then into the Cisco 1841 which does the dialer PPPOE authentication.

How many site-to-site VPN can we establish in Cisco router 1841. When we start 1841 we get the message that VPN Module 1. What is the meaning of it, does it mean that we can establish only one VPN. How about the limitation of GRE VPN Tunnel.

Cisco VPN :: 5505 Connection To Mapped File Shared Dropping On A Site-to-Site VPN

Nov 27, 2011

We've just deployed a site-to-site VPN using a 5505 ASA on the client's site and a checkpoint Nokia FW on our site. Everything seems to be fine except that the user's connections to their file shares seem to be intermittently dropping. One minute the connection to the shares is there, next thing it's lost. There is no logic to it because no two users are experiencing issues at the same time, as a matter of fact even on the same PC where a user has access to 3 shares on 3 different servers, one could be showing as connected whereas the other two be dropping. [code]
As you can see the Duplex and Speed are set to auto, I've rectified this since then and I'm keeping a close eye on the output errors, and collisions. However, I'm afraid that this did not rectify the issue and the users are still experiencing intermittent connection dropping to their file shares over the VPN!
