This has been resolved. I upgraded to 1.3b18 and the phone registered as soon as m0n0wall had
finished rebooting. Don't know what is different in this release, but I am happy that all is working
as it should.

Subject: [m0n0wall] Public IP Address Setup
I needed to renumber my home network as someone here wanted to be able to
connect to a Zyxel ZyWall VPN that wanted to use 192.168.1.0 as the "remote"
network which became an issue as our local network was already
"192.168.1.0/24". I decided I would take this opportunity to get rid of NAT
all together and setup real IP addresses on all machines. I am fortunate to
have an ISP that gives IP's away for nothing, so I got hold of a /27 and set
m0n0wall is running with PPPoE and is automatically assigned a WAN address,
I have my /27 setup as the LAN address, and then a separate DHCP machine
handing out addresses. All PC's are working just fine, they can browse the
internet, VPN even works OK now.
However, I have one issue which is confusing me. I have a Polycom IP320 VOIP
phone which connects to a hosted VOIP server. I have given the phone a DHCP
exclusion, and set the necessary boot server options and the phone boots OK,
downloads the config files via FTP.
When it then tries to register via SIP, it decides to use the WAN address of
my m0n0wall and not it's LAN IP address. Note that when it's downloading
the config files via FTP, it uses it's LAN IP as expected. Obviously my WAN
IP is not expecting SIP registration packets to hit it, so it ignores them
and my phone remains unregistered.
I cannot figure out where I have gone wrong here, and it may have nothing to
do with m0n0wall at all, but it's the first place I am looking.
I have advanced outbound NAT enabled, with no rules configured. Is there
anything else I need to configure to convince this phone to ALWAYS use it's
LAN IP and not my WAN IP address ?
FYI I have been running Wireshark on the hosted VOIP server and can see that
the SIP register packet has the correct IP address in the SIP part, but in
the IP wrapper it has the WAN IP. m0n0wall 1.3b15 is in use.
Thanks for your help!
