FreeBSD-4.1.1-Stable Box-A= gateway Box-B= Apache, ircd, etc... servers I'm not able to redirect *only* http/https incoming-packets on my outside interface to a box on my local network. Below if from my /etc/rc.conf and /etc/natd.conf; - natd_enable="YES" natd_flags="-f /etc/natd.conf" natd_interface="de0" - redirect_port tcp 192.168.0.2:6667-7000 6667-7000 <-- this works fine redirect_port tcp 192.168.0.2:25 25 <-- this works fine redirect_port tcp 192.168.0.2:80 80 <-- this will *not* work redirect_port tcp 192.168.0.2:443 443 <-- this will *not* work While these redirects are in place, I have used anonymizer.com to make it seem I'm on the outside of my local network and, surf to my URL using a FQDN and alternatively my ISP assigned 'ip'. I then view my ipfw logs on box-A with; tail -f /var/log/security which shows the following; Dec 23 20:48:55 Box-A /kernel: ipfw: 5100 Count TCP 216.34.244.18:32176 my.external.ip:80 in via de0 - I now do a tcpdump -i de0 (while anonymizer.com tries to surf as described above) results show below; 21:03:36.298039 bellatrix.anonymizer.com.2783 > my.external.ip.http: S 276149746:276149746(0) win 32120 <mss 1460,sackOK,timestamp 1419389851 0,nop,wscale 0> (DF) My take from this is, the gateway is seeing the packets. At the same time on box-B, I am doing tail -f /var/log/security and i see nothing hitting the apache servers ports. I have tried using other ports in place of 80 and 443, but, the redirects to my *known* working Apache does not happen. assistance needed.
