Please help: Cisco 831 blocks Nortel VPN client

Unanswered Question
Feb 21st, 2007

Hi Guys,

Hope someone can help me with this issue:

Our main Cisco tech is on vacation, and unreachable at the moment. So here it goes:

There is one desktop in the office with Nortel Contitivity client. User used to access some site via Nortel VPN, router had been swapped with another one and now user has no luck connecting, receiving something like: "VPN client terminated connection...."

Thing is that problem was with old router also, and Cisco tech fixed it pretty fast. I believe that UDP, ESP and AH have to be allowed. Ports UDP 500, TCP 50;51.

There is no outbound access list, only extended inbound,

So, after I unsuccessfully tried to allow port by port, I tried to open access up completely with entries to named extended access list:

Permit tcp any any

Permit ip any any

I put these entries at the top of access-list,

That did not help...?

I am not very experienced and certainly will appreciate any advise.

Thanks,

Alex

I have this problem too.

Are you using any external DHCP sever ,if so try to increase the time for getting the ip address. Coud you capture teh log files of the failed connection.
