Hi List, Until recently, I've been running an Asterisk server behind an MS ISA 2004 firewall. In general, this has worked fine - I've been able to connect to my SIP provider to make/receive calls (sipgate.co.uk in the UK and callcentric.com in the US), and DHADI runs the one traditional analogue line I have here.
Then, the ISA server went pop, for the umpteenth time. Rather than replace it with yet another flaky second hand Dell server, I've put a spangly new 64-bit HP server in, which needs a 64-bit OS, hence Linux Mint. And, because I'm not entirely sure how well (if at all) ISA Server would work in a VMPlayer, I decided to use Linux's approach to firewalls, aka IPtables, using the GUI program fwbuilder. I finally got most of my network going through iptables/fwbuilder, but I cannot for the life of me make Asterisk talk SIP to the outside world. All attempts to register with sipgate fail. Callcentric appears to register OK, but attempting to make a call and it throws a critical packet not received error & aborts. I have (I think) port forwarded 5060 UDP, 5060 TCP and 10000-20000 UDP to the Asterisk box, as well as IAX2. IAX2 works just fine, I have an external phone connected in using it. Has anyone used fwbuilder to create the rules required to let an Asterisk server make & receive calls via SIP? Thanks in advance, Ade. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
