My ER-3 is setup as follows:
eth0 - 192.168.1.0/24 - LAN
eth1 - 192.168.2.0/24 - GUEST LAN
eth2 - WAN
My WAN cable router comes with it's own built in WIFI and DHCP server. It also happens to be in a location in the house where we don't get good wifi reception from the main APs so it is handy for that. It is also where I have my HDHomerun interface connected (it takes in coax from an HD OTA antenna and then makes that live TV streamable over the network to any device.
The problem I've run into is that the WAN is on a different subnet and I can't get the two to communicate. I have the WAN DHCP configured to use the 10.0.1.0/24 range and I've assigned a static IP of 10.0.1.177 to the HDHomerun device.
So 3 questions:
- How do I go about making the WAN 10.0.1.0/24 range available to my eth0? Is that a rule on eth2 somehow? Right now eth2 interface address is set to dhcp, do I need to change that?
- If not 1 than is there someway to NAT that 10.0.1.0/24 subnet to make it work?
- Finally, I don't want eth1 to have access to any of these WAN IPs with the exception of that 10.0.1.177 IP so that it can stream the TV signal. So after figuring out the first part I'd need to figure this out.
Sorry if these are dumb questions, I'm pretty clueless when it gets into anything beyond the simplest of networking. Much thanks for your time.
