No,
it's a standard ADSL router. I've reset the router to it's default
settings so it only does NAT, without DMZ, without any port being
forwarded.
I've tried again with port 5060 -> same problem
Tried with port 5070 -> everything works fine..
just out of curiousity, is there a logical explanation for this?
thanks,
Bart
