VPN connection issue; no data passing after connection

Hello,

Our company has Cisco 3030 VPN Concentrator's which have been in place
for about 2 years now. The issue we are running into is if any user
is NOT behind a NAT device they will be able to connect but will not
be able to receive any traffic through the Concentrator. This only
happens if they connect via the Ethernet 2 (External) interface. They
can make a successful connection and pass data through when connecting
via the Concentrator's Public interface (Internet). We have a TAC
case opened with Cisco but they haven't come back with anything yet.
Anyone out there having this type of issue or have any advice on what
to verify/check on the Concentrator as well as the client's config.

Thanks,

Brian

This isn't for internal folks connecting to your own vpn concentrator
is it? Sounds like a familiar problem that requires some special
configurations if this is the case (related to routing back to the
internal network through the public interface). If its strictly
external users, then not really sure.

You could always ask your users to Drive Golf Carts to the buildings
they are trying to connect to. This would cut down on network
bandwidth as well as erase your need for a VPN Concentrator?
