pfSense - Traffic to subnet not being routed by static route
Solution 1:
If you can access (ping) the management IP from the pfsense but not the computer segment, it would be easiest to add a hybrid NAT option to pfsense with something like this: (switch GUEST for Opt1Phone), it's likely the device you're trying to access doesn't have a return route.
You do not need a static route for directly connected networks.
