Got a problem where we use a Cisco VPN Concentrator 3015 serries.
Peeople are fine using it for remote access. But we found a problem today at a client site. We have 2 users connecting through an ADSL 4 port router and once logs on OK , but when the other logs in it logs the other person off.
Looking at the config on the VPN Conc. under-
TUNNELLING AND SECURITY
It has port 10000 as the TCP port, but none of the checkboxes are checked for IPSEC over TCP and IPSEC over NAT-T
PAT is being used.
Is there a quick fix for this. When connecting on 2 separate ADSL lines it works fine. So I am not sure if it is the Router or the Config of the Concentrator
Any help welcome
