Since my network a AT&T Home Base 4G LTE wireless router is behind a NAT connection finding a solution was very difficult for me.

Finally I found a workaround.. Added two files: rpt_extnodes and astdb to /var/lib/asterisk/  from a Debian DIAL node that was connecting to all HUBs or nodes throughout the allstar system.

Now my ASL v 1.0.1  node is connecting fine...

Thanks all for your sugestions.
