Disable tcp 1723 and 10000 on Concentrator?

Hello,

Where di I need to go on the Concentrator to disable tcp 1723 and 10000?

We don't require these to be open and our pen test shows these as being open.

Thanks

Disable tcp 1723 and 10000 on Concentrator?

To disable TCP/1723 (PPTP):

http://www.cisco.com/en/US/docs/security/vpn3000/vpn3000_47/configuration/guide/tunnel.html#wp1008446

To disable TCP/10000 (IPSec over TCP/10000):

Configuration | Tunneling and Security | IPSec | NAT Transparency | untick IPSec over TCP

Hope that helps.
