Yet Another Long Night

Posted Wednesday, May 31st, 2006 9:31:00 am
I hate it when I get momentum to work on something after midnight.

So I took a look at Reborn's ipfw/natd problem today. I actually tried to use pf, but I couldn't get anywhere with it, so I started to try to resolve the existing problem. I did succeed in getting the DNS working, although that was more of a problem with dnscache not able to listen on multiple addresses than with ipfw/natd. One problem solved.

The other problem had me baffled, though. I had absolutely no ability to VNC into my internal network from outside, where I had before I "upgraded" to FreeBSD 6.1. This is because I lost all of the configuration files when I went to upgrade.

Anyway, just tonight I figured out my problem. Basically, a remote machine will send a request to Reborn on a port that it is to forward. It does this fine, and the machine it is forwarded to processes the request fine, returning it to Reborn. The problem is when Reborn sends the response back out, it is sending it from the wrong address, namely the local ten-dotted address.

And I have absolutely no idea how to fix it.

But at least I know what the problem is now. Hopefully I'll have one of my Linux techie friends know what's wrong with my configuration and be able to fix that.

But for the love of Chick-Fil-A sweet tea, it's 4:30 in the morning, and I have a meeting in 5 hours. The curse computers put on us these days.
