Hi, Newbie here. I got a XP Home SP2 with DI-624C router (DSL_PPPoE) and Sygate Pro. Here are my current rules but I would appreciate your suggestions on rules such that both firewalls work together. Thanks in advance. Router: Disable WAN ping. Other than this, firewall is not yet enabled. If I were to enable the hardware firewall, its top rule would block all incoming connections from WAN to LAN. I am concerned that this would interfere with Sygate rules below so I leave NAT fw inactivated for now. Any suggestions? Sygate: 1) Allow incoming/outgoing ICMP types 0,8 2) Allow incoming/outgoing traffic from/to all hosts on UDP remote ports 68,137 to/from UDP local ports 67,137 3) Trust IP of ISP: allow incoming/outgoing traffic to/from all ports on IP protocol type 69 - 206 4) Applications: allow ISP mail servers and Firefox, etc.
