Yes. In fact, that's my real problem.
When I try to connect to my SIP proxy (Asterisk) from internet, I come from 
ppp0 address.
However, Asterisk decides to reply with ppp1 address sometimes. And then I can 
not register, because my sip client does not accept the reply from ppp1 address.

Even if the connection was from the net and entered on ppp0?

Try ensuring the following two modules are disabled.  For me if they are 
enabled, it breaks SIP.  I see I have this disabled on both the firewall 
machine and the asterisk machine (CentOS5, 2.6.18-348.18.1.el5 kernel)

 

# grep sip /etc/modprobe.d/blacklist.conf

install ip_nat_sip /bin/false

install ip_conntrack_sip /bin/false

 

 

Does that really help about my problem ?

I don’t see them in my “lsmod” output. So they are already disabled ??
