Did you actually create a bridge device on the Pritunl host?

It isn’t recommended to use bridged mode. It is most likely not the correct configuration for the use case. No online cloud providers support a bridged network. The virtual VPN network should be routed instead by removing NAT from the local network route and adding the virtual network to the local network routers routing table.
