Hello,
I'm considering testing the Vonage service, with my FreeBSD-4.10 system (maybe 5 or 6). I wonder if anyone here has a configuration they can share, or if there are any pages out there that detail the proper (and secure) setup.
i'm using lingo (www.lingo.com) - very similar to vonage. i use freebsd 4.10 as my firewall/nat/wireless access point/etc. the lingo box in behind freebsd box. it gets its ip (local) via dhcp and then talks to the lingo servers (via nat). it seems both providers are using sip, so i did not have to open anything on my nat/firewall, because the lingo box initiates the connection from the inside.
I can understand how you can do outgoing calls behind a NAT firewall, because you initiate the connection. But can you receive *incoming* calls? Or are you always "connected" to the VOIP provider, and thus your firewall/reverse-nat is always open/setup?
Thanks, Gary
