Cisco VPN client & Terminal Server

ldoyle — Fri, 21 Feb 2020 06:29:41 GMT

Have a customer who is connecting a remote office to a central office. Each remote office user has Cisco Secure VPN Client. Remote office is connected to Intenet with 827.

Each user in the remote office can make a VPN connection just fine through the 827; however, they cannot simultaneously use terminal server client.

I suspect PAT is involved, but not sure how to configure the 827 to allow multiple VPN/TS connections.

Thanks in advance.

Hi doyle,

What is the VPN head end device? If it is VPN3K , IOS, or VPN5K, you should be able to use NAT Transparency to be able to overcome the PAT problem

Thanks for the reply, jazib.

On the Cisco Secure VPN clients, they're using transparent tunneling with IPSec over UDP. I am told the head end is a 3000.

Is there something I need to do to the 827 to use NAT transparency? The 827 is running IOS 12.2(4)YA3....I fear it neds an upgrade.
