Dual-routers causing issues.

[odrusso]

Hi,

I have 2 routers in my 'house' (One in my house, and one in my sleep out), and they seem to be causing some 'issues'.

My network setup is as follows (Paint FTW):

 

So the issue in question, is that I am unable to access anything from 'across the border' on the "Wifi #1" for some reason. On my server I have Plex and basic Windows 8 Share NAS running, and the only way I have found to get this to work is to port forward the IP & port of plex, the connect via my external IP. This unfortunately doesn't work for the Windows Drive Shares. Any questions about my setup, please ask

 

Thanks.

Make sure that only one router is setup as a router and the other one is set to Access Point (AP) mode, because you don't want it to do anything else (like hand out IPs etc). 

 

Also, over WiFi, can you try this command

ping <ip of server>

Of course, substitute it with the IP of the server. Do you get a response back or some type of "host unreachable" error?

enable UPnP on the inside router and disable its firewall. Then make sure the one on the outside has a good firewall. You will also have to put both routers DHCP server's to assign different ip-spaces withen the same sub-net.

 

An easier method than that, is to do everything on a single network. You can follow these steps:

 

1: Assign the outside router the address 192.168.1.1

2: Assign the inside router the address 192.168.1.2

3: Disable the DHCP server on the inside router, and link the two via LAN ports (dont use any WAN ports, or this wont work)

4: Set DHCP on the outside router to assign IP's to 192.168.1.3-192.168.1.254

 

This is what i do to setup new wireless access points using old wireless routers. I basically turn them into a gateway, and let the main router handle the rest.
