Bandwidth.com SIP Trunking
I have signed up to test one of their SIP trunks for 30 days. They are telling me the IP has to be public and cannot be natted. I have a public IP on my Cisco Firewall but I am using NAT which I would think most others are as well. Seems to be an issue (to me) hanging the TrixBox out on a public IP ? What have you guys done to resolve this issue ? I know several people here use Bandwdith.com and I have read good things about their service. I know I can change the server but I also have other SIP trunks that work fine via a natted firewall. Any input would be appreciated very much.

We run many trix boxes behind a PIX. I am still using conduits however the same would apply to access lists.
This is from my own office PIX (6.2)
Value1PIX# show conduit | include maitrix conduit permit tcp host maitrix eq 5060 any (hitcnt=0) conduit permit udp host maitrix eq 5060 any (hitcnt=0) conduit permit tcp host maitrix eq 4569 any (hitcnt=0) conduit permit udp host maitrix range 10000 20000 any (hitcnt=1) conduit permit icmp host maitrix any (hitcnt=0) conduit permit udp host maitrix eq 4569 any (hitcnt=2) Value1PIX#
4569 is for AIX so you can ignore that.
Before you comment on the absurdly low hit counters (even I am impressed) this system is using IAX trunking. This config is for SIP and IAX.

Thanks for the replies guys. I told them to move forward with the setup they "warned" me again it might have only 1 way audio so I will see how it goes once they notify me its ready. I will assume I can get it working based on your experince with them.
