Since 192.168.1.x subnet is on the inside of the network, your FBSD box
will never route a request for an IP on that network outbound by
default.

I may be shown up here, but you will probably be best changing your
internal network to another subnet 192.168.0.x perhaps, and then your
FBSD router should pass toward the Internet a request for 192.168.1.100,
and hopefully the comcast modem will catch it.
