I have one server (SBS2000) with ISA (integrated mode). My server have two NIC. One for LAN and one to ADSL Router. I have more public IP address. The router NAT public address. The NIC on the server have more IP (10.1.1.3, 10.1.1.4, etc) but no one can ping me. Only NIC primary address (10.1.1.2) pinging trough public address. I have tryed configuration: 1) add incoming web request IP 2) Enable IP Routing 3) Add packet filter ICM Ping query for the address but don't work. Please HELP ME! Corrado
