I'm running 2.4.22 now and have a NAT behind my firewall as well as IPv6 happily run through unixcore.com. I upgraded to 2.4.22-bk2 last night to fix an odd problem where I can't ssh-6 to one host. All of a sudden it all works within the nat but nothing behind the firewall can get out from behind to the real work though the firewall still can. Recompiled trying 2.4.23-pre1 and I get the exact same behavior. All 3 use the same .config file. The only noticable change I can see is a bunch of messages: Aug 27 22:09:10 wally kernel: MASQUERADE: No route: Rusty's brain broke! Aug 27 22:09:16 wally kernel: MASQUERADE: No route: Rusty's brain broke! Aug 27 22:09:16 wally kernel: MASQUERADE: No route: Rusty's brain broke! As soon as I reverted to 2.4.22 everything works great again. Attaching my .config. Please contact me directly if you need any additional testing done.
