Re: Cannot connect to static IP computer
said by officederamo:Ugh oh. The SIP product is deployed from a separate cable modem and SIP proxy box (commonly referred to as a Back-to-back user agent). How is your IP-PBX connected to that B2B box?
The splitter is just where the electrician did the wiring so that we can access both WAN and LAN's. Splitter is probably the wrong term but I don't the technical term.
The IP's after about 7 hours have reverted to not responding. The last hop before the static IP is 220.127.116.11.
I am also an Optimum SIP truck customer and my network consultant is asking that dept for help too. We'll see what happens.
Under NO circumstances should you use a SHARED ethernet segment (= switch) between the LAN side of the DPQ3925 static-IP router and the LAN side of the IP-PBX/B2B-box, or even the LAN side behind your NAT router: You MUST keep that traffic truly separate+private - the risk of conflicting IP spaces and host IPs (between what your NAT'd network uses and what the IP-PBX and possibly your VOIP phones use) is just too great: This is beyond your skill level.
I am highly suspicious about your statements that "whatsmyip" (do you mean »www.whatsmyip.org/ ?) is showing you different IP addresses from the same machine at different times - at ALL times should it show you the same IP out of your pool of 5 statics. If it doesn't, your machines are clearly changing networks (more than one DHCP server in the same ethernet L2 space!), and you have some shared ethernet (layer-2!) connecting something improperly. However: I can't think of a scenario that would make whatsmyip to display anything but a publicly routed IP, ever - it should never ever be capable of displaying private RFC1918 addresses (192.168.x.x among others).
