VPNs and Firewalls

Can someone just specify what considerations are required when tunnelling a VPN through a firewall? Such as IKE requiring UDP 500 and so on....? I am facing differing problems with VPN clients in NATing and connectivity...Thank you for your help.

Re: VPNs and Firewalls

Protocols 50 and 51 for ESP and AH and UDP port 500 for IKE. Also, AH seems to have problems with NAT.
