[asterisk-users] asterisk-users Digest, Vol 54, Issue 107

[bilal ghayyad]

Sorry, but does that mean if I disable the iptable still I have to do something else? I am talking about Fedora.

Also, do I have to give the extern ip to be my DSL router public IP? What it if is dynamic, so I have to put the ddns name?

Regards
Bilal
