Hi,
I have been in IT industry since 15+ years now have been part of many network and VoIP deployments,
have been using DD-wrt since 2007 to deploy wrt54g routers instead of expansive cisco routers to save money for small clients who needs BGP to be configured,
kindly let me know when can we have some chat and fix the issue you are having.
to set it up you would need to have an internal web server to authenticate the request form the users.
regards,
