Depending on the configuration I got different "Q931d Could not open/connect socket at a.b.c.d:e" errors. In my setup, I had a machine with two interface addresses plus one loopback address. What I wanted to achive is simply to accepting calls coming from the one interface (but directed to the loopback address) and to proxy them over the other interface -- kind of what a Cisco "Router" does. > The best place to start is the simplest.

Today it works with or without those settings ... Oh how I love those non-reproducible problems :-( What worked even yesterday was setting the "Bind" address to the Loopback address, while not setting the "Home" parameter. Which leads to the question what differences there are between "Home", "Bind" and "Network Interfaces" and how they interact. My understanding is as follows: Home: Listen and accept calls from there. Bind: Use this as source address for outgoing connections. > [Proxy] > ;;InternalNetwork=171.42.0.0/16 I used "InternalNetwork" and "ProxyAlways". > Gatekeeper(GNU) Version(2.3.2) Dito, from recent Debian testing package. > schematic setup: http://pastebin.com/0ektd8nE Just add a well-known loopback address and it will be the same as mine. RAS was not used. So as I mentioned already it works like a ipv4 dial-peering Cisco "router". Regards David -- David Dahlberg <david.dahlberg@xxxxxxxxxxxxxxxxxx> Fraunhofer FKIE, Dept.
