Here is the my config to allow X-Lite outside network to connect asterisk server behind NAT:

sip.conf

externip = external_ip

[xlite]
;Turn off silence suppression in X-Lite ("Transmit Silence"=YES)!
;Note that Xlite sends NAT keep-alive packets, so qualify=yes is not needed
type=friend
regexten=401 ; When they register, create extension 401
username=xlite
secret=password
context=default
callerid="Vincent Li" <401>
host=dynamic
nat=no ; X-Lite is behind a NAT router
canreinvite=yes ; Typically set to NO if behind NAT
disallow=all
allow=ulaw
allow=gsm ; GSM consumes far less bandwidth than ulaw
mailbox=401@default

Then port forwarding sip controling 5060 and rtp port range 8000-20000 from my linksys router to my internal asterisk server

So the NSLU2 is flashed with unslung linux firmware, I followed the http://www.nslu2-linux.org/wiki/Unslung/Asterisk and http://www.nslu2-linux.org/wiki/Unslung ... ionForSlug to initally set up my first open source asterisk pbx system. I tried the softphone xlite from my powerbook to ibook labtop, it did not work at the network of my working place (UBC), but it does work at home network. here is a snap shot of my NSLU2 asterisk pbx box with two xlite on two mac laptops:
