Firewalls in FreeBSD?

Right now I have a Windows machine a FreeBSD natd/firewall then a
cable modem.
This is working for web surfing. But I've been playing a lot of games
lately and it doesn't work at all (for multiplayer/internet games).
Basically the games send/receive data on random ports, and I think
it's going out fine - but doesn't come back in.
Is this a problem with nat or because I have a stateless firewall?
I've played around with this on and off for the last while and haven't
gotten any where with it.
Do you think this would work better or at least be easier to
configure/debug if I moved to pf instead?
Do I need to run natd if I run pf?
