Summary:                    [patch] sip_nat_settings - script to generate
externip and localnet
Description: 
If an Asterisk system is behind NAT, SIP calls outside will usually have no
audio unless externip and localnet are set.

In most cases (a single network interface) it is possible to give a sane
value for localnet. figuring out externip cannot be done locally. I simply
ended up asking http://whatismyip.org/ (and big thanks to whoever set it
up). 

Naturally those are sane defaults only if I know in advance that the
system is behind NAT.

I used it with asterisk 1.4 on several occasions. AFAIK it is still needed
(and with the same ocnfiguration directives) in trunk.

Example output:

externip = 62.90.10.53
localnet = 192.168.0.255/255.255.255.0
