Cisco VPNClient's TCP port number

Our mobile users is at a client location and the VPN client work fine until the client put in a firewall and have many restriction on the Internet traffic. The network admin now want to know exact tcp port the CiscoVPN client use so he can allow it through his firewall.

My question is the VPN client said default is UDP and the TCP port if use need to match with the VPN server. Is it correct to say the VPN server will use the port 10000 as default port? and how do we config the server to use another TCP port number

Thanks,

BD

Re: Cisco VPNClient's TCP port number

Hi,

TCP port is configurable under ,configuration->tunneling protocol->Nat Transparency, and you can configure upto 10 ports for that(separated by commas).

10,000 is default.

Thx
