Hi there

this is an interesting topic that I see here and a problem that I am trying to solve too.

But I was wondering if the forwarding solution will work for my case.

So I have two Asterisk boxes A and B.

A is behind a corporate NAT such that A can SSH to B, but not vice versa( "One-way SSH" ) . The UDP port 5060 of the corporate NAT is blocked off and I will not be able to have it unblocked for security reasons.

Hence, is my only choice using an SSH tunnel between A and B for the IAX connection to work? Will it work though with that "One-way SSH" factor mentioned before?

Thanks
John

Hi;

Via OpenVPN or port forwarding is known for me, but
via SSH is new for me, how I can do it and what is the
difference by SSH and OpenVPN?

Good question. I have never tried tunneling IAX over
SSH but it seems
like
it should work just like anything else.

How about a port opened up for OpenVPN. You know you
can run IAX on
any
port you wish, port 80 may work for you if you have
some extra external
IPs
not being used for HTTP. The same is true for
OpenVPN.

Thanks,

It is possible to run openVPN in TCP mode over an SSH tunnel. Don't turn
compression on on both though - I'd just switch it on the openVPN if you
have to.

You will probably find the speech is rather choppy due to the delays and
fragmentation, but I have done this.

Hi;

How can I use SSH in that senario? Is there a link
that can help to understand what I have to install and
to configure?
