Xlite on external not register on DMZ?

I have install asterisknow behind NAT, but I make DMZ to asterisk address, so I can browse GUI from remote, but the X-lite not see my the asterisk server? I try also to make DMZ on client, but is not help, how I can find out what the problem?

Did you try sip debugging and seeing if anything is coming in ? Try forwarding the ports and see what happens.

Now after I replace the router on server side and make DMZ to asterisk, the all work fine. brobably somthing stuck on the old router.

I have a small little gray hair called NAT. I got it from… NAT issues !!!

Glad that you were able to resolve your issues.
