Static route error- can't ping server to client
Hi,
I need two routers to communicate by PPTP. The TP-Link router is working as server. The TP-Link network is 192.168.16.0 while the other router (other brand) is responsible for network 192.168.20.0. This network is connected to another network (192.168.180.0). So, my idea is to ping network 180 from network 16. This needs to be done through internet.
Until now I can ping network 16 from network 180 and 20, but cant ping network 180 and 20 from network 16. My suspicion is that the tp link router doesn't know the 20 and 180 network. So, I need to make a route on tp-link side. The thing is the gateway, by what I saw on internet, needs to be the gateway of remote router (network 20). But if I put this gateway an error occurs saying I need the gateway to be on the same network as the device (tp-link). What should I do to ping the network 20 and 180 from network 16?
Thank you
