I tried both of those and got the same result, ping: sendto: No route=20 to host. I examined my dmesg output a little closer and noticed: IP Filter: v3.4.35 initialized. Default =3D block all, Logging =3D = enabled This means that my assumption of disabling IPF by removing all of the=20 comments tertainin to it and IPNat from /etc/rc.conf were wrong because=20= it it compiled statically. This means that there is no way to turn it=20= off, right? So I reloaded my old /etc.rc.conf with the somments to turn on IPF and=20= IPNat, and point to their rules files. The previous computer this HD was installed on had two NICs sis0 and=20 sis1. sis0 was connected to the WAN, so I just changed sis0 in all the=20 comments to dc0. I made sure there was a statement that allowed ICMP=20 statements thru. I restarted, and things stayed the same, so I went back to=20 /etc/ipf.rules and changed all instances of sis1 to dc0, also maing=20 sure the ICMP statement was there. I restarted again and, once again ,no progress. Since the previous=20 machine had two interfaces this is most likely the issue since nat is=20 messing things up. I have to get moving forward with this project so I am simply=20 downloading the new 6.0 release. This should solve the problem.
