I'm not a pfSense expert... is that semicolon a comment symbol, or
are those two commands?

It makes some sense to me... the 10.10.10.0 network really only exists
for Client C, until you add routes to pass traffic over the VPN as well.
Just for safety's sake, I'd test to see what other machines I could reach
on the 10.10.10.0 network, from server B. If Client C has forwarding
turned off, then you're probably ok. Otherwise, you might be exposing
more than you realize. And same for machines on 10.10.10.0 reaching
server B. If you add a route on Client D to pass all 192.168.150.0
traffic to Client C, can Client D get to Server B?
