Hi, One of my nodes (2482) sits behind an ADSL connection with a dynamic IP address (changes any time the router is re-started etc). For a while, all was well, and it appeared on the status pages on the website. Following a few network upsets (i.e. renewed IP addresses)- but no configuration changes - the node no longer appears in the list. I modified the "statpost_program" line in rpt.conf to direct output to a file, rather than /dev/null. The resulting file contains this one-liner: Error! Not Authorized from IP 80.65.243.181 The IP given is the correct public IP that my ADSL router currently has assigned to it. As far as I can tell, the "register" entry in iax.conf is correct - I certainly never changed it after it was initially working. Any Ideas?? Thanks David Osborn - GD4HOZ
