If you have used the FWD Assistant, it will have configured your
Asterisk server to use FWD through IAX, not SIP. Since you seem to be
behind NAT and a firewall, using IAX is a good idea anyway. IAX is NAT
friendly, SIP is not.

As far as your X-Lite connecting to Asterisk goes, I presume X-Lite
and Asterisk are running on different Macs, is that correct?

If so, you need to find out if that wireless bridge you're talking
about uses NAT between your X-Lite Mac and your Asterisk Mac. SIP
doesn't work well with NAT and that is probably the reason why you
can't get through to your Asterisk Mac. You could download iaxComm (an
IAX softphone - link on the MacOSX page of the Wiki at
www.voip-info.org) and again use IAX instead of SIP.

In any event, if you want to use Asterisk as a "VoIP Hub" instead of
connecting to FWD directly from your softphone, then the chain would
be like this ...

[softphone]---internal extension--->[asterisk]---FWD number--->[FWD]

Wherever there is NAT between two points in the chain, you are saving
yourself a lot of trouble if you use IAX instead of SIP for that
particular connection, but you don't necessarily have to use the same
protocol all the way. Asterisk can translate between SIP and IAX for
you.
