What port #s does VPN use?

[gilbert.florescu]

I have a 515 PIX that's running VPN. I'm trying to connect to it from home but I can't connect due to my firewall at home. If I turn off my home firewall it works just fine...

I need to open up ports on my firewall at home but I don't know what ports I should open.

udp 500

udp 4500

ip 50

That did not work. I enabled port forwarding for UDP 500, UDP 4500, TCP and UDP 50, and GRE.

I'm using an ActionTec DSL modem.

port forwarding is not going to work, as esp is ip 50, not udp or tcp. and the same reason for gre as it is ip 47.

assuming you are running vpn client software on your laptop, you shouldn't need to implement port forwarding. all required would be to allow ipsec to pass through.
