Remote phones connecting in

Is it possible to connect a remote phone that would be located in a home office to connect to the Asterisk system without a hardward firewall. I know I can do it with a hardware based VPN tunnel, but that is not a great option for me. I want to do this without opening a bunch of ports on the server in the office. Any ideas?


This means you already have a firewall in place so your question does not make sense. And its a hard question to help answer if you don’t give more details about your network config.

Try just leaving port 5060 open on your firewall, make sure this is forwarded to your server if its not on public ip, and see what happens.
