[Asterisk-Users] SIP registration behind Linksys WRT54G

[Mojo-Jojo]

I have a whole Asterisk server behind a wtr54gs. We have SPA-2000's 
registering from the Internet into it with no problems.

Actually, we don't have it at the moment but did for several months.

Not sure if this helps any or just adds to the confusion.
