Hi, I'm currently trying to use a local instance of freeswitch as a test/dev environment for embedding voice & video in an application. It's version 1.5.12b 32bit running on windows 7. The trouble is, nothing I do seems to prevent it from opening access to the outside world, so I'm ending up with loads of attempts to register from 192.111.153.106. My config is currently in a hacked/broken state such that they can't authenticate (and I've changed the passwords anyway), but it's a damn nuisance. I've tried adding -nonat and -nonat -nonatmap to the startup parameters. I've commented out the <param name="ext-rtp-ip" value="auto-nat"/> <param name="ext-sip-ip" value="auto-nat"/> values in both external and interal sip profiles (and renamed the external one to a non xml extension so it doesn't get read). I've also tried setting those parameters to invalid values. I've searched over and over and dug through documentation. Nothing seems to work, this external connection still keeps trying to authenticate with various extension numbers. Please, am I missing something obvious here or something? It seems strange that it would be so difficult to lock the thing down for testing. thanks, Charles.
