How to make communicating with each other clients on different subnet ?

« on: March 13, 2021, 02:35:05 pm »

I need a client on subnet 192.168.0.1/24 (LAN) being able to ping another client which is on subnet 192.168.10.1/24 (LAN2) - and viceversa.

LAN and LAN2 are on two different physical Ethernet ports of the OPNsense router.

I'm playing with Firewall --> NAT --> Outbound, but no luck s far

Can someone help, please?

Tia.

Just add a LAN rule inbound on the LANs in question allowing traffic from the other LANs

So add a rule on for subnet 192.168.10. to allow traffic from the specific address on the 192.168.0 subnet. i.e if the client is 192.168.0.23, add a rule for that client. Better still make an alias for it and just use the alias.
