I'm thinking of subscribing to CallVantage. From what I read, one\nthing that concerns me is their D-Link telephone adapter looks like it\nhas to be installed between my cable modem and router.\n\nMy concern's are:\n\nI have a web server on my network using a dynamic DNS service\n(DNS2GO). Its local IP is the one entered into my router that "pokes\nthrough it (DMZ)." It's used for development, and not really used\nmuch to serve pages over the internet, but from my understanding, when\nI want someone to browse something on my webserver, I'll need to\nremove the telephone access device each time and plug the router back\ninto the cable modem. Otherwise the router will only know about the\nlocal IP being fed to it by telephone adapter.\n\nI sometimes also use a service called RealVNC for remote accessing my\nnetwork. The same problem will happen here too. NetMeeting the same,\nalthough I don't really use that service.\n\nSo I need suggestions on what to do, configuring my router (a Linksys)\nand telephone adapter.
