Hello everyone.

This is my network:

[FritzBox – 192.168.123.1]-----ethernet-----[Ubiquiti LBE-5AC – 192.168.123.3]-----WIRELESS_BRIDGE_5GHz-----[Ubiquiti LBE-5AC – 192.168.123.4]-----ethernet-----[TP-LINK Archer C6 – WAN=192.168.123.5 / LAN = 192.168.1.1]

The FritzBox is my main router, connected to the internet. 

TP-LINK Archer C6 is my second router connected WAN to LAN to the FritzBox router.

I have two different network as you notice from the above scheme(192.168.123.0 and 192.168.1.0).

All i want to do is to gain access to the TP-LINK network(192.168.1.0) from the FritzBox network(192.168.123.0).

I configured ip route table in the FritzBox as below:

Network = 192.168.1.0

Netmask = 255.255.255.0

Gateway = 192.168.123.5 (WAN IP of TP-LINK)

but i still don't have access.

I tried to use an old router with DDWRT firmware and the ip route works.

Is there any setting to set in the TP-LINK router ?

Thank you!
