Allow traffic between subnets
I have 2 interfaces (LAN and OPT1.) LAN is 192.168.1.0/24. OPT1 is 192.168.2.0.24. In firewall rules I allowed traffic from both subnets on both interfaces. Firewall logs show traffic is allowed, but communications still fail. How do I set up routing to allow, for example, 192.168.1.10 to talk to 192.168.2.10?
There is no special requirement, you only need the correct firewall rules in place. The default LAN to any rule should allow access to opt1 from LAN without changing anything.
How are you testing? What rules do you have in place?
I run the same setup with the same address space and there is nothing you need to do other than allow in firewall
What are you rules on your opt1 interface. You do have devices on the opt1 network pointing to the pfsense opt1 IP as their gateway, these would be really the only requirements.
OPT1 interface is a separate VLAN. Could that make a difference?
If you creating vlans then yes could be causing you your problems
Why do you need a vlan if your interface is on different segment, do you need to tag it for some reason.. Is it connected to a switch port in trunk mode?
What exactly are you wanting to accomplish? You have 2 network segments - why do you need vlan?
Is your LAN interface also a VLAN?
OPT1 is connected to an access point that tags traffic based on SSID. One SSID is guest network that only needs access to WAN (VLAN 50.) The other is should really be a bridge to LAN, but my understanding is that bridge with LAN is out of the question because of VLAN so I figured pfSense can just route between subnets if I set it up as a completely different interface.
You should be able to bridge LAN to another interface no problems even if that interface is the parent of another vlan.
So you have 3 NICs in your pfSense box?
Maybe time for some screenshots of your setup.
Here's the layout:
WAN (BGE0) - Public IP
LAN (BGE1) -192.168.1.0/24
WiFI (BCE0) - 192.168.2.0/24
WiFi Guest (BCE0/VLAN50) - 192.168.3.0/24
I didn't want to mix tagged and untagged traffic, but I can't figure out a better way to do this without a managed switch and that won't arrive for some time.
I attached screenshot of firewall rules for LAN and WiFi interfaces.

Well that all looks ok. How are you testing this?
Are your wireless clients correctly receiving IP info from pfSense via dhcp?
You can probably put both ssids on a vlan so you aren't mixing tagged and untagged traffic but I'd wait to get this working first.
I wasn't testing correctly. Communication does work. Thanks to everyone for help.
