I'm attempting to set up an Asterisk server with clients as follows: SIP Client 1 (HT 286) === NAT ===> ===> Internet ===> ===> NAT === * Server === SIP Client (HT 286) 2 The crux of the matter is this: I have a client behind a NAT trying to connect to an * behind a NAT. I'm looking for suggestions on how best to tackle the problem. Although I'd prefer to have Client 1 connect directly to my * server, it's acceptable for Client 1 to connect to another service (FWD, etc.) and have my * server register with the service as well if necessary. I have the option of disabling NAT or putting some equipment into a DMZ. Can you offer some suggestions for what my network topology should look like to get Client 1 connected to my * server? Thanks, Richard
