Hi, I've got a router Zyxel P314 with DSL an fixed IP 80.xx.xx.xx This router send all incoming PPTP on the port 1347 to a W2K VPN Server. Beetween my router and the VPN Server I would like to Install ISA. I've got 2 NIC on ISA one on the same network of my router 170.xx.xx.xx and one on my LAN 192.XX.XX.XX. How can I configure ISA to let vpn packets passing thrue ? Thanks
