VPN Ports needed for NAT

[GNiessen]

What ports do I need to setup in NAT to use VPN with my Cisco 678 router? I have three computers, but only need the VPN to work with one. I have already setup ports for other apps like NetMeeting and Game Voice.

But I can't seem to find out what VPN needs.

What kind of security protocol are you using? IPSec, PPTP, etc.

Microsoft VPN (PPTP) uses ports 1723 and 47. IPsec is vendor specific but will be documented in the VPN user install guide.

The security is IPSec. And is for a Cisco 3000 on the companies side. I already tried opening all ports with out success.
