Hello, I'd like to have my Asterisk server available to IAX softphones and hardphones with dynamic IP on Internet. For some obvious security reasons I'd like to configure a firewall to avoid people to hack the Asterisk server and use it to have free communications. I'm sure it is a popular question, but I haven't found anything about that online. Thanks for your help, Benoit -- Benoit Merouze Network Software Developer - IPercom benoit.merouze@ipercom.com
