At present, I'm using FreeBSD 4.10-Stable and ipfw (not ipfw2) For example, if rc.conf had just the bare minimum: firewall_enable="YES" firewall_type="OPEN" natd_enable="YES" what would a STUN client on a private subnet see ipfw/nat as, a Full Cone, Restricted Cone, Port Restricted Cone or Symmetric NAT? I've tried with a few stun clients myself, but get conflicting results. I'm interested in what ipfw/nat is meant to be? Thanks, MikeC
