Communicate Between 2 different networks

2016-05-15 17:58:35 - last edited 2021-08-21 06:56:07

Model : R480t+

Hardware Version :

TL-R480T+ v7.0

Firmware Version :

1.0.0 Build 20141208 Rel.36351s

ISP : FiberLink

Please help me to sort out how to communicate between 2 different networks.
i am using Load Balancer R480t+ as a internet Gateway.
Networks are
R480t+= 192.169.4.0
cisco e900 wifi router connected via r480t+ using wan and
Cisco e900 lan network= 192.169.2.0

i cannot ping 192.169.4.0 to 192.169.2.0 but 192.169.2.0 can ping to 192.169.4.0

Note: The lan connected directly through r480t+ lan ports use pppoe service while e900 thier wan ip is excluded in r480t+ pppoe services and e900 get ip through dhcp from r480t+.
I am not using any smart managed switch only R480t+ is using.

Hi ahsun, as we know the TL-R480T+ and Cisco E900 are both NAT devices. So your network can simplified as ISP---NAT1---NAT2---Clients, due to that the devices outside the NAT cannot access the devices inside the NAT INITIALLY, no wonder you can not ping 192.169.2.x from 192.169.4.x. If you need to do that for some special application, you need to use the Port Forwarding function or DMZ.
