Hi,

Good day,

We are trying to establish connection between two different networks.
For this we are using three TP Link TL WDR3500 routers.

TP Link Router 1:
=============

DHCP server is enabled in this and from this routers LAN side the other routers (also TP Link TL WDR3500) WAN side is connected.
The DHCP server network range is : 192.168.11.0/24

TP Link Router 2:
=============

As said above to this routers WAN port TP Link Router 1 is connected.This routers WAN is getting IP in the range 192.168.11.0/24.
DHCP server is enabled on this router which provides IP in the range of 192.168.20.0/24.
FYI, our devices are getting IP in this range.

TP Link Router 3:
=============

As said above to this routers WAN port TP Link Router 1 is connected.This routers WAN is getting IP in the range 192.168.11.0/24.
DHCP server is enabled on this router which provides IP in the range of 192.168.30.0/24.
FYI, our devices are getting IP in this range.

The devices in the range of 192.168.20.0/24 is not able to reach the devices in the range of 192.168.30.0/24.

Thanks

What are you trying to fulfill?
If you want devices connecting to Router 2 and Router 3 can communicate with each other, they should be in the same subnet.
Now they are in different networks and it is normal that they cannot reach each other.

As @M Diamond said, it is normal.

But you can try the following, I know some routers allow routing in this way.

#On router2 (Assume its WAN IP is 192.168.11.100, LAN is 192.168.20.x)
Go to Advance routing to create a static route, destination is 192.168.30.0, Mask 255.255.255.0, gateway is router 3's WAN IP address(192.168.11.200).

#On router3 (Assume its WAN IP is 192.168.11.200, LAN is 192.168.30.x)
Go to Advance routing to create a static route, destination is 192.168.20.0, Mask 255.255.255.0, gateway is router 3's WAN IP address(192.168.11.100).
