Hi, I have RVS4000 configured to listen to multiple IP on WAN side.For this to work my config is like this: WAN WAN holds the "routing" segment 188.8.131.52/31 of my public IP subnet WAN IP static: 184.108.40.206 WAN gateway: 220.127.116.11 LAN Lan holds the first IP of my public IP subnet 18.104.22.168/28 LAN IP static: 22.214.171.124 LAN subnet: 255.255.255.240 Everything else under LAN settings is empty. Advanced Routing Here I have: Operation Mode: ROUTER RIP: ENABLED RIP Send Packet Version: RIPv2 RIP Rcvd Packet Version: RIPv2 So, practically I have LAN side configured with public IP and no NAT between WAN and LAN side. PROBLEM here is "single Port Forwarding", for example: 1.) I have 2 mail servers behing RVS4000, so I want to open port 25 on 2 IP addresses...but I can't! Cisco says, that 2 rules of port forwarding are the same and does not accept one of them. Any idea? 2.) Some single port forwarding rules simply do not work?! Straight forwarding a port xx to xx works, but from port xx to YY does not...or it does, until I add another rule. Meaning, that if at some moment all port forwardings work, they may NOT work after I add another rule. Any idea....except of buying at least 800 series?
