We have a Concentrator 3005. The tunnels are from 2 Client 3002's. All systems but 3 can be seen on the concentrator side, it is some kind of IPSec issue, because a PPTP VPN can see everything with no problem. Please help if you can.
This document shows the matrix support for which versions of Cisco VPN Clients, VPN Concentrators, Cisco IOS? Software, and the PIX Firewall support IPsec/Point-to-Point Tunneling Protocol (PPTP).
