My mission is to get one * box to dial another * box' extensions. I have set this up previously without any issues by making a simple IAX trunk/extension pair on the two boxes and create a dial plan with a prefix like 9|XXX to select an extension on the other box.
My problem is that I now have to do this with extremely restrictive firewalls thrown into the mix - firewalls I have no control over. Basically, the setup is: *1 <---> FW1 <---> (Internet) <---> FW2 <---> FW3 <---> *2 I have control over firewall 1 and 3, but not 2. Using port forwarding (4569 UDP) on FW1, I have been able to make calls from *2 to *1. My problem lies with making calls the other way, as I have no way of port forwarding on FW2. My initial thought was to set up a reverse SSH tunnel from *2 to *1, which would have worked fine if SSH would tunnel UDP (latency is a different matter altogether). I found a software called Zebedee (http://www.winton.org.uk/zebedee/) which claims to do UDP tunneling, and is able to do it "in reverse", but I can't for the life of me get it to work. Before I try further with Zebedee, I thought it wise to ask the * community if there is a standard solution in this particular case, or perhaps if I'm attempting the impossible. Any input is greatly appreciated. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
