Hi
Also I have not changed default gateway on PC (200) from the router address (193)If I change it to (221) the pfsense address then I lose internet access
Should the default gateway for lan side pc's be the wan address on pfsense or the ip address of the router?
If you want the LAN side PCs to connect to the pfSense web GUI then their default gateway needs to know how to get to the pfSense LAN address. When a LAN side PC attempts to connect to the pfSense web GUI at 192.168.1.1 it will see the destination is in a different subnet so will send it to the gateway. Does the gateway know where to send it next? I suspect the router (193) doesn't.
If the LAN side PCs run Windows, the commands ping and tracert can be helpful investigating these sort of problems. The equivalents on many Unix systems are ping and traceroute.
As to what the default router should be I'll leave that to someone else because I don't have experience or knowledge of how bridge mode works.
