[Asterisk-Users] Asterisk SIP between two networks

[Sergio Serrano]

Hi all,
	I have next configuration:

		SIP Provider<--------------->ADSL router<---localnet
192.168.20.0--->ASTERISK<---localnet 172.24.240.0--->softphones

		first localnet 192.168.20.0
		second localnet 172.28.240.0
	in second localnet we have softphone and the first localnet is
connected to ADSL router to connect to our SIP provider.

The problem is the next:
	if I put in [general] section in sip.conf, bindaddr=0.0.0.0, I
can't register in my SIP provider. If I put 192.168.20.10 in bindaddr I
can register in my SIP provider but softphones can't register into
asterisk.
I 'm using asterisk RC1. 
	
	Any idea?
