hi, making may way through all this...internal sip registration works,(cant call yet but anyhow)... the asterisk box is obvisoulsy behind a router. im not 100% sure if i should go with port forwarding or NAT and if a or b, what additional setup is actually correct? sip_nat.conf # this is when i got the NAT -route, right? #gets all the dyndns-stuff #externip = home.mydomain.com (Enter your DynamicDNS domain name. Obviously it's just easier to get a static IP address and avoid using DynamicDNS altogether.) externhost = home.mydomain.com externrefresh = 5 (which means lookup hostname every 5 minutes to refresh ip adress) localnet = internal.network.address.0/255.255.255.0 thx -------------- next part -------------- An HTML attachment was scrubbed...
