I can't reach devices from my subnet

[Shorosky]

Hello:
I configured my router (TP-Link 1043 ND) as routed client according to this section:
https://openwrt.org/docs/guide-user/network/routedclient

My configuration is:

(Subnet 192.168.2.1)Router TP-Link (main net 192.168.1.90) ---------WiFi----- main router (net 192.168.1.x)

But I can't reach the main network from my subnet.
If I try to do:

PC(subnet:192.168.2.x) -----------------------SSH----------------->(main net:192.168.1.x)Device

It doesn't work.
However, if I do:

PC(subnet:192.168.2.x) -------SSH----> Router TP-Link --------SSH---------->(main net:192.168.1.x)Device

I can reach the device using TP-Link CPU as a middle platform.
It seems, something is blocking the access from the subnet to the main net.
I have deactivate masquerading for 192.168.1.x net and firewall Accepts blocks from Subnet to net, and from net to subnet.

It's becoming me crazy.

Thank you.

Add route to subnet 192.168.2.0/24 via host 192.168.1.90 on your main router.

Sorry, it didn't work:

I still doing ping from TP-Link router to main router, but from my PC.
What am I doing wrong?

Thank you, vgaetera.

uci delete firewall.zone[1].masq_dest
uci commit firewall
service firewall restart

After that you should be able to access 192.168.1.0/24 from 192.168.2.0/24.

uci delete firewall.zone[1].masq
uci commit firewall
service firewall restart

This should help to access 192.168.2.0/24 from 192.168.1.0/24.
But the condition is upper level router allows LAN-LAN forwarding and has correct route to 192.168.2.0/24.

Also make sure destination host firewall allows traffic outside of LocalSubnet scope.
Usually that's a Windows specific issue.

Thank you, thank you a lot!!
It worked!!
I have to say, that trying it, at first it didn't work and I changed the netmask of my computer from 16 to 24.

I really thank you.
Best regards.
