Hi Stewart, True, I can forward the required ports but doesn't that mean I can only forward to one IP address inside the NAT? The product I have seen did not publish any documentation (proprietary, I guess), but I have seen it work, running on H323, without any config changes on a Linksys router. It was almost plug and play, provided the EP has been pre-configured with the E.164 and the outside GK info. Just a thought. -----Original Message----- From: openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx [mailto:openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Stewart Nelson Sent: Wednesday, November 10, 2004 12:08 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: GK for Behind-of-Linksys Router Endpoints Hi Fernando, > I have noticed that if I have an endpoint connected to a Linksys router, or > some other dumb router, I need to DMZ the EP. Not quite true, you just need to forward the required ports. > What happens then if I have multiple endpoints behind a single dumb router? If the endpoints can use different signaling and media ports, no problem. For example, the ATA-186 looks like two independent endpoints and works fine. However, this is an administrative hassle if you have many endpoints on different private addresses. > Not sure how other developers did it, but I saw a product that allows > multiple endpoints behind the dumb router, without any "special" config > changes on the router, register to an outside GK, receive inbound calls from > the PSTN, and make outbound calls to the PSTN. > Is this possible with GNUGK? You can run gnugk behind the NAT and have many local endpoints register to it. However, you still need the NAT to forward required ports to gnugk. I can't see how the product you describe could work with a "generic" outside GK; I'd appreciate a link to the documentation. Also, I suspect that the outside GK would have to proxy everything, which is a performance problem in many cases. While it is often useful to put an endpoint behind a NAT over which you have no control, e.g. in a hotel, it is hard for me to imagine a situation where you install multiple endpoints, yet are not granted the right to have some ports forwarded. Could you please give some more details about your application? If you are just trying to provide PSTN access to multiple users at a site, similar to Vonage, Packet8, Broadvoice, etc., IMHO you should use SIP, just like those providers do. --Stewart ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________________ List: Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Homepage: http://www.gnugk.org/ ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________________ List: Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Homepage: http://www.gnugk.org/
