[BUGS] firewalls

[Glenn]

Hi,
at home I have a DSLG604 ADSL router with built in fire wall. The fire wall is configured to allow all traffic out and no traffic in. 
My workstation (FBSD 6.2) does not run a firewall and I'm wondering if I should.

Other machines on the network run Windows and have a firewall enabled so I
guess I'm feeling a bit "naked".

Do I really need one and if yes would pf be a good choice?

Glenno,
Sydney.
