Re: Access list

The IP protocols necessary to forward through a Firewall for VPN traffic are:

47 GRE

50 ESP

51 AH

The UDP/TCP Ports necessary to forward through a Firewall are:

UDP 500 ISAKMP

TCP 80 (HTTP)

To allow mail and browsing through network neighborhood, allow these ports:

TCP 25

UDP 137

UDP 138

UDP 139
