[asterisk-users] Security - Using Linksys PAP2T from outside with a dynamic IP is there anyway to block all other traffic but those of the PAP2T?

[bruce bruce]

Hi,

Can you please explain the DynDNS part. How would I put that in my Asterisk
server as an identified party? Usually it comes to me with IP address
(dynamic). Or do add something like this in sip_nat.conf:

externip=mybox.dyndns.org
localnet=192.168.0.0/255.255.255.0

???

Thansk again,
