so from researching on the net it seems that, it is either the "ACCESS LIST" or the CRYPTO MAP
i am not sure. Plus i am not too familiar with the CLi.

i can reach the router and login thru SSH from the outside.

Please assist, thanks in advance.

Firewall must be configured to permit UDP ports 500 and 62515 whcih are
required for cisco vpn client.

also The message means what it says - your client cannot connect to the remote site.
Has it ever worked?
If not, then you need to look at the router or firewall that is protecting the branch office from the Internet to ensure that it has VPN pass through capabilities.
If you are using a PIX to protect the branch office then there is a command that needs to be entered in to the PIX to allow VPN pass through.

Hope this help


In my first post I assumed in your ACL 104 that X.X.X.x was the source IP address was for the VPN client.  If that is not the case and X.X.X.X is the source address for the site-to-site IPSEC remote end the you need to open up the ACL.

access-list 104 permit udp host X.X.X.X host eq isakmp
access-list 104 permit udp host X.X.X.X host eq non500-isakmp
access-list 104 permit esp host X.X.X.X host

You need to make sure you allow both the site-to-site in the ACL 104 and the remote access VPN clients.  Typically you will need to change to this to a source of any as the remote access VPN clients could be anywhere.  You might also need to add UDP port 10000 to the ACL if you configured your Cisco VPN client to encapsulate IPSEC in UDP.  Port 10000 is the default port for this.  

I am assuming when Vikrant mentions port 62515, etc he is talking about ensuring that the if the PC with the Cisco VPN client on it has a "personal firewall" installed to ensure that these ports are allowed to talk to itself.  This should be an issue with the MS built-in firewalls but could possibly be an issue with some 3rd party products.

You should also investigate using ISAKMP profiles as I stated in my last post.  When you start having mulitple type of IPSEC VPNs on a IOS router it can get confused about what to connect to what.

hello thank you for responding. I m very sorry with such late reply as i has to go out of town for family emergency.

the issue has been resolved with removing the old vpn settings and starting fresh with 2 new policies as suggested by norgetek.

Thank you both of you for responding and taking the time out to help.
