[Asterisk-Users] FWD<->NAT<->*

[Joseph]

I found this configuration file on Wiki for FWD behind firewall

; SIP Configuration for Asterisk
;

[general]
disallow=all
allow=ulaw
port=5060			; Port to bind to
bindaddr=0.0.0.0		; Address to bind SIP channel to
externip=xxx.xxx.xxx.xxx
localnet=172.16.1.0
localmask=255.255.255.0
context=inbound-sip		; Default context for incoming calls
maxexpirey=180
defaultexpirey=160
tos=reliability
srvlookup=yes
register => FWD#:secret at fwd.pulver.com/FWD#


bindaddr=0.0.0.0  - is this the address of my asterisk server
externip=xxx.xxx.xxx.xxx  - this is my external IP before firewall isn't it?

When I try to register, I get: sip_reg_timeout: Registration for ...

What am I missing?
