I've upgraded freebsd from 7.0 to 7.3 and all was good until I tryed to configure gre interface and use ipfw fwd. I'm actually does not know what was the point of failure in my configuration. I got freebsd 7.0, next i made csup and: make buildworld && make kernel KERNCONF=MYKERNEL reboot to single user mode mergemaster -p make installworld make delete-old make delete-old-libs mergemaster -iF reboot And made some test to check that 7.3 works well. It worked about one week and then I made some configuration changes: added gre interface and 2 aliases: # cat /etc/rc.conf |grep ifconfig_xl0="inet 192.168.0.10 netmask 255.255.255.0" ifconfig_xl0_alias0="192.168.0.11 netmask 255.255.255.255" ifconfig_xl0_alias1="192.168.0.12 netmask 255.255.255.255" cloned_interfaces="gre0" ifconfig_gre0="inet 192.168.250.6 192.168.250.5 tunnel 192.168.0.12 192.168.200.15 netmask 255.255.255.252 link1 up" and # cat /etc/rc.local #!/bin/sh ipfw add fwd 192.168.250.5 icmp from 192.168.0.11 to any out via xl0 ipfw add fwd 192.168.250.5 tcp from 192.168.0.11 443 to any out via xl0 ipfw add allow ip from any to any # ifconfig gre0 gre0: flags=b050 metric 0 mtu 1476 tunnel inet 192.168.0.12 --> 192.168.200.15 inet 192.168.250.6 --> 192.168.250.5 netmask 0xfffffffc I shutted down gre interface to prevent requests via gre to buggy IP. The main idea of such configurations was: fwd all connections to https to 192.168.0.1 via gre interface. And also I made apache configurations to make it listen on 192.168.0.11 too. And make some tests: ping 192.168.0.11 - was fine, goes via gre. Telnet to 192.168.0.11 443 was fine too. Then I tryed to make browser https connection to 192.168.0.11. Apache showed me certificate warning and I accepted, then in browser nothing happened, it was trying to open page. But server got kernel panic at that moment. At first time I thought that it was some power failure, I tryed 2 more times and got same behaviour. So https works without kernel panic via 192.168.0.10 address but kernel panics when I try do https via 192.168.0.11 address that source-forwarded via gre.
