I keep forgetting that, thanks!

So to recap in a single post:

In sip.conf

[general]
port=5060
; other stuff

externip=your.ip.addr.here
localnet=192.168.0.0/255.255.255.0
nat = yes

; further down in friend defs
; a SIP phone
[2000]
type=friend
;
nat=yes
canreinvite=no

Forward from router all WAN request on these ports to asterisk local ip address
Port 5060 
Ports 10000-10100

anything else you need, such as ssh, http, IAX2...
