[Asterisk-Users] secure

[Altus Syman]

I'm a bit new to this,so sorry,but,help me if I'm right
I have 2 companies ,2 asterisk servers different extensions .Both 
servers act as router,got a wan and lan IP
I configured the servers with IAX on the WAN ip so that each company can 
call each other without bracing out to the pstn!
No I want to secure the wan side!The servers are only running asterisk 
,so ,on the lan side I can close all ports and only open IAX pors(Dont 
know out of my head).Both internal networks are trusted so the wanside 
are all open.
Sorry if my terms arnt that good
This sound right
