[CoLoCo] changing subnet mask

[Jim Hutchinson]

I put a second router on my network because I'm having problem with the
first (seems broadcom adapters don't want to connect - it's running a new
dd-wrt and I'm thinking that is part of the issue). Anyway, the first router
is on 192.168.1.1 and hands out DHCP on 192.168.1.100-150. The second router
is on 192.168.2.1 and hands out DHCP on 192.168.2.200-250. My main desktop
is connected to router 1 and cannot "see" router 2. In order to admin router
2 I have to direct connect another computer. I'd like to be able to see it
from my desktop. I'm guessing I need to change the subnet mask of router 1
so that it can see devices on the .2.x network. However, I'm not sure how to
do or what the ramifications might be.

So far, my googling is telling me that unless all devices on both networks
have their subnet changed to whatever the new subnet is I'm asking for
problems. Is this true? Is there no way to just make computers connected to
router 1 see router 2? Also, what is the proper subnet mask to do this? I
found one suggestion of 255.255.252.0 and it said that would show everything
from 192.168.0.1 to 192.168.3.255 (I think). Not really what I want but I
guess it would work.

Can anyone verify if that is okay and what I might be risking/breaking by
changing?

Thanks.
