Model: TL-WR902AC  
Hardware Version: V3
Firmware Version: 0.9.1 0.3 v0089.0 191018

Hello,

installed the new travel router, set up router mode, set up static ip and found out that I can reach out the devices on the other subnet(192.168.1.0) with the devices connected on the wireless network(192.168.3.0) but, on the other hand, the same thing cannot be done if I try to reach from 192.168.1.0 to 192.168.3.0.

the 920AC can be detected by Advanced Ip Scanner, but doesn't respond to ICMP on cmd.

Tried to do some static routing on the main router but didn't work(as below):

Someone knows how to solve?

Thanks in advance.

@Steven_Ji 

 

May I know the network layout? Is this 192.168.1.0 the WAN subnet of the WR902AC? If you want to access the WR902AC LAN from WAN, you need to open the corresponding ports for the specific IP address on the WR902AC network to allow that. You can refer to this guide to open the ports:

Thank you fo replying. Yes, the 192.168.1.0 is the WAN of the nano router. Can I somehow open all ports for all the devices on 192.168.3.0 without opening them one at a time?

Update:

After hours of looking around I found "SPI firewall" in "Security" and "basic security" section, disabling it allowed me to lower the firewall and allow all packets on all ports toward all devices(except for the 192.168.3.1, why?).
