We can't reach the public IP addresses on our in-house server (host unreachable) from our NAT clients, but the rest of the Web and our internal networking is fine.
Here's our topology:
Server NIC #1: 192.168.0.7/255.255.255.0 <---> Hub
Server NIC #2: 220.127.116.11 - 37/255.255.255.0 <---> Hub
Cisco 675 DSL Router Ethernet: 192.168.0.1 <---> Hub
Cisco 675 DSL Router WAN: 18.104.22.168(Gateway)/255.255.255.248
Clients: 192.168.0.10/255.255.255.0 (DHCP on router) <--> Hub
The public addresses are hosted on our server and are also shared via NAT.
I tried setting up routes for each public IP to a private IP, but my servers became unreachable.
(I have yet to find a Cisco 675 NAT configuration that works for blocks of multiple IPs that also need static routes.)
I have two NICs so that I don't have file and print sharing on my public IPs and I can do port filtering at the NIC.
Why would the public IPs that I'm hosting be unreachable by my clients? Is there a simple fix?
