First: I can ping just about any address I care to. DNS is working, because hostnames are converted to IP's Any machine behind the firewall can telnet/rlogin/etc just fine. My firewall directives are very close to those found at: http://www.mostgraveconcern.com/freebsd/sheet.cgi?ipfw Now, the problem is that I can telnet/rlogin to some sites, others I can not. In particular, I can't telnet/rlogin into my ISP (access. realtime.net) from my firewall machine, nor can it access the SETI web host to send/acquire work units. On the other hand, it has no problem with another ISP (io.com) and www.freebsd.org. Anybody want to hazard why I can't rlogin/telnet to any sites? About the only clue I have is that I get ACK packets from machines/ sites I can connect to, none from machines/sites that time out.
