Hey to all

 

I have issue with TP link MR6400. 

Setup:

I have two networks. Network A has 192.168.1.0/24, network B 172.17.38.32/29. Network A has TP link that is default gateway for that network, one computer and one more router that separates network A and network B. (like in picture) Computer in network B cant ping computer in network A but can ping TP link. Computer in network A can ping computer in network B. Can some1 explain why is this happening? Does TP link has some firewall protections?

The reason for this behaviour could be the switch between MR6400 and PC0 or the PC0 itself (its firewall settings).

If you can ping MR6400 from PC1, there's no reason you can't ping the PC0, since it's in the same subnet as MR6400 (192.168.1.0/24).

You can start troubleshooting by connecting PC0 directly to the MR6400 to exclude the switch issue possibility.
