Localnet in Asterisk configuration

hello guys.

i wanna ask about element “localnet” in sip.conf file that some tutorials use that element for asterisk’s configuration. is it important to be specific with the IP of my computer? if i set “localnet” with it’s default, is there some problem will come in certain case ?


It is never necessary to specify the IP of your computer. You should not even specify IP’s, only network ranges.

If you need localnet at all, it is to specify which sub-networks, other than the directly connected one, are on your side of a NAT device.

The default is not but <your IP address>/<your subnet mask>. (More correctly, I think it is nothing and the local network is always added, but it does no harm to add it explicitly.)
