Hi Michal, What I have seen was this "proprietary" GK and all that was needed by the endpoints was broadband connection. The EPs can be public or private. And it allows multiple EPs behind a single Linksys router. -----Original Message----- From: openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx [mailto:openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Zygmuntowicz Michal Sent: Wednesday, November 10, 2004 12:23 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: GK for Behind-of-Linksys Router Endpoints One side note: You don't have to forward any ports if you have a child GnuGk gatekeeper behind NAT and its parent is also GnuGk. The child must be running in a proxy mode, the parent should have at least ProxyForNAT=1 set. ----- Original Message ----- From: "Stewart Nelson" <sn@xxxxxxxxxxx> Sent: Tuesday, November 09, 2004 5:08 PM > 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.
