Let me try to explain how my setup is so theres no confusion. My main router is a E3000 running Tomato. It is directly connected to the cable modem and serving the internet for the entire house and its various devices.
I also have an E2000 that I also put Tomato on and configured it to be a Wireless Ethernet Bridge on N only on the 5ghz band. I had to use this bridge for a workstation that is setup in another room (my wifes home office desk). See my wife and I both work from home and she wasnt getting my office so we set hers up in another room. But that room didnt have a hardwired LAN so couldnt connect all the devices. In her desk area there is a VoIP Polycom phone, Network Printer, her Laptop. So basically when she docks the laptop all 3 of these devices would be using the E2000 to Wireless Bridge to the E3000.
Now currently I have just the Polycom VoIP phone hooked upto the E2000. The E2000 has an IP address itself of 192.168.0.10 (My E3000 is 192.168.0.1 which I forgot to mention). Now when the VoIP phone registers it works fine. But I noticed on the E3000 devices list I see two IP address that are the same. One which belongs to the Polycom VoIP and the other that is also listed for the E2000. Screenshot below.
First I guess I want to ask is there a problem in this setup? I not exactly a hardcore network guy, more like intermediate. Once I start put say the laptop on it and it gets it own IP, it also has the same duplicated one pointing to the E2000 (on the screenshot the E2000 MAC is the one that starts with C0:C1:C0). So basically each device that connects (via hardwire) to the E2000 to Wireless Bridge to the E3000 seems to get this duplicate IP address of the E2000 as well.
If this is a problem, whats the way to fix this? How do I get it now to show this 2nd IP of the E2000 for each legitimate device that is connected?
