My OpenWrt router is running on 192.168.10.0/24
I have another network 192.168.12.0/24
From each network I can reach any ip address in both direction except my OpenWrt router(192.168.10.2)
My OpenWrt routers address (192.168.10.2) can only be reached from and communicate with devices on the same LAN subnet 192.168.10.0/24
I have tried different things such as network alias, adding the address to 192.168.12.2/24 to the LAN interface but I'm not able to make my OpenWrt router(192.168.10.2) visible for LAN subnet 192.168.12.0/24.
I have tried adding an alias and the other subnet to the LAN interface and more, but without luck.
Could someone please share what I need to to?
Thank you in advanced for any guidance and support
What is the purpose of the second router in your network? OpenWrt can actually run multiple subnets which means you can potentially eliminate one of the routers entirely.
Importantly, does the first router support static routes (if OpenWrt, the answer is yes)?
My second network 192.168.12.0/24 is my VPN tunnel network runnig OPNsense.
Eveything is working as expected in both networks in both directions except for the OpenWrt router.
OpenWrt router 192.168.10.2 can't see hosts on 192.168.12.0/24 and wise versa.
I noticed that all clients without a firewall on the LAN network 192.168.10.0/24 were reachable out box after setting up the VPN tunnel network 192.168.12.0/24 where as for windows clients I nedded modify firewall rules allowing traffic from 192.168.12.0/24
Since OpenWrt has a firewall I suppose I need to somehow configure it to allow traffic from the network 192.168.12.0/24.
I have now noticed that on my OpenWRT LAN interface, that has a static IP, I had not in "Interfaces > Advanced settings" enabled the "Use default gateway" option
This was not relevant in my former setup.
Now it's all logically working as expected.
