We have PIX515 firewall with outside and inside interface.We have Cisco VPN 5000 Access VPN client in one of our machines on the inside network. We are trying to access a VPN 5000 concentrator on the outside network. What are the ports that need to be enabled in the Firewall. We have a DES license in our firewall. But the VPN 5000 server runs 3DES. Does it matter for access VPN's thru Firewall.We are not establishing LAN to LAN VPN.
