Does anyone know what/if any routers support a block of multiple public IP addresses? Is this possible to do WITHOUT using 1 to 1 NAT? Basically I want to be able to forward any public IP:Port to any local IP:Port
public -> local
188.8.131.52:100 -> 192.168.1.5:100
184.108.40.206:101 -> 192.168.1.6:101
220.127.116.11:100 -> 192.168.1.7:100
18.104.22.168:102 -> 192.168.1.5:102
I have a Cisco RV180W but its awful and horribly buggy. The only way I can get it to recognize multiple public IPs is via 1 to 1 Nat, port forwarding was broken in general until a recent firmware release and even the most recent firmware has glaring bugs regarding firewall access rules noted in the "Known Issues" of the release notes.
I'd just like to replace the router, but with limited networking knowledge I'm finding it difficult to figure out what/if this configuration is supported.
