Using CM 1200, Four WAN IP Addresses, Router configuration for each WAN IP?
I have an ISP with four WAN IPs. I have a CM1200 to deploy each IP. I have two RAX30 routers to seek to have an external IP go to an internal LAN IP address. The first router, with IP of 10.1.1.1, th...
I do indeed have 4 IP's. This configuration looks like it would work, however, what are the appropriate Subnet maskes? 255.255.0.0? And how do I get to the appropriate LAN devices?
We have to share LAN servers. We are a small consulting business. Servers can have multiple addresses, but what gateway IP do I use on the servers?
We used to have ways to create static routes to other networks, but I don't see that in the documentation and I am not network literate, but able to follow directions.
I thought the CM 1200 documentation would show.
Use default SNM, 255.255.255.0
Gateway IP would be same as IP addresses of the router as I suggested for each.
The CM modem is just that, a modem only, no routing here. Any static routes would be made on the wifi routers themselves. I'm not experienced in those features so you may need to see help for static routes online.
Ok. I have done enough to know that configuration, would work. 192.168.nn.1, where nn is 1,2,3,4 and each with the 255.255.255.0 subnetmask.
The port forwarding would be straightforward it I had four servers.
I have two and they intertwine. One web server and one sql server.
And it doesn't appear that I can share the DMZ between the routers, which was my original intention and have the servers to be in the DMZ. This may be possible, but I am having some trouble setting up the DMZ.
I have network connections and switches and I have tried to use those to assist the connectivity. I can see, ping and connect devices only it on a single network.

No you can't use DMZ on each router to interface between them. The DMZ is only for putting something on the LAN side to the WAN side that by bypasses the firewall for this one item in the DMZ only. Remember each WAN IP and router connected to it is it's own separate network and WAN IP address from the ISP.

Correct.
