Hey everyone,
I am thoroughly impressed with EQEmu, I think its great.  I started looking into running my own server on the lan here at home and finally got everything working (except for the patch process 

).  It's really easy to use, once I got it all figured out.  Downloading everything and patching EQ over my 56k was a bit tiresome, but everything else was awesome.
Anyway, I noticed some people had posted on the boards saying they were having trouble finding their external IP, especially if they're behind a firewall or router.  There's a great little program for that, called Follow-Me IP.  Runs in the system tray and reports your IP.  You can find out what your IP is just by double-clicking on the icon in the system tray, and it reports accurately even from behind a firewall or router.  here's a link 
fmip.org.
Hope that helps.
