Hi Adam, I have a similar network, but am using hardware gateways rather than NetMeeting. The problem is that the incoming leg of a call is started by GnuGK opening a TCP connection to the destination party and sending a SETUP message. The NAT won't normally pass this (nor subsequent H.245 or RTP traffic). If, for example, you set machine1 as the DMZ host on natbox1, and machine3 as the DMZ host on natbox2, you should be able to call from machine1 to machine3 and vice-versa. Depending on the type of natbox1, you can probably call also call from machine2 to machine1 and machine3. You won't be able to call machine2. If you need to have multiple endpoints behind the same NAT that can receive calls, you may be able to configure them with different call signal ports, and set the NAT to forward the various ports to the appropriate machines. However, AFAIK NetMeeting can't do this. Your other choices include running another GnuGK behind natbox1, or running one as natbox1. If that's the only location with multiple endpoints, you won't need a separate 'proxy' server. --Stewart ----- Original Message ----- From: "Adam Wendt" <adam@xxxxxxxxxxxx> To: <openh323gk-users@xxxxxxxxxxxxxxxxxxxxx> Sent: Tuesday, June 01, 2004 7:30 AM Subject: Proxying Calls Across the Internet > Ok so here's my setup > > machine1-----machine2 > | > natbox1 > | > internet------proxy (server running gnugk) > | > natbox2 > | > machine3 > > natbox1,natbox2 and proxy have public internet IP addresses. machine1 > and machine2 are on one private network behind natbox1, machine3 is on > its own private network behind natbox2.
