How do I route between interfaces in PFsense?
Firewall rules are correct. Probably a host firewall, or wrong subnet mask on a host, or missing/wrong default gateway.

I have a PFsense router which divides a single WAN connection into three NAT networks on three interfaces: LAN, OPT1 and OPT2. This allows me to segregate my network so that computers on the OPT1 and OPT2 networks can't reach servers on the LAN network. This is working fine.
There is a single server on the LAN network which I want to allow computers on the OPT2 network to connect to via readonly NFS. I have added firewall rules allowing traffic from the OPT2 network to the IP of the server on the LAN, but yet I still cannot connect.
How do I route between two interfaces in PFsense?
EDIT: Here's screen captures of my rules. I'm trying to allow computers on the FOREST interface (
172.16.1.0/24
) to access mission (192.168.1.107
) over SSH. I used SSH because I know it's port 22 and I canssh -v
and see if it connects or not. It does not:-

Admin over 7 yearsHmm. The order of the rules matters, the tip rules are processed first. You may want to re-order your rules.

Admin over 3 yearsSame issue here. Rules are "correct" and can't even ping across the subnets... There has to be some other configuration step, because this "just doesn't work"

Josh over 12 yearsThe host has no firewall... All machines can contact internet servers just fine so I doubt it's a missing/wrong gateway. It could possibly be a subnet mask issue, but I am pretty sure that the subnet masks were all set correctly...
