I need to know what ports are needed open for vpn connections both tunnel and client.
My internet connection is threw a group that supplies internet securing and other software solutions.
They have a firewall in place (ASA I think) and I have a firewall that connects to there network.
What I need to know is that is that ports that the provider needs to open so that I can connect remotely to my network.
I have a 515 with v6.3.5 configured with isakmp, ipsec, using des encryption.
