Hello!!!
First, yes I know it's an obsolete device.
Second, I am trying to setup a home lab using 3 Routers/Switches (Residential Gateways, you know what I mean).
I have a problem, which is that I want to have two separate networks conected with the DPC2325 Gateway, but I am not being able to do it and there's a page in the GUI which I am unable to access, it's labeled as "Advanced" (the one at the right) and it has different credentials, which I haven't been able to find in the internet or manuals.
The main problem I have is that I can manage to make a PC in it's network connect to the network on the other Router, I can do the inverse (from the other network to the Cisco one). Personally I think it's a Gateway problem (it's not configured, I can only do it in WAN settings which obviously doesn't work).
