[asterisk-users] several behind NAT

[Todd- Asterisk]

Just to report back in, the advice of the list was to not worry about  
it- they should work well.  I took a DSL modem with a router on it  
and connected both phones (Grandstream GXP2k and 101)- they did not  
work.  I found that I had to program in a STUN server.  I also has to  
set it to use a random port instead of the default- a pre-defined  
port (else only 1 phone would ring regardless of extension).  Now  
they both work well.  Does anyone see a problem with this setup?   
Should I use my own STUN server? or can I continue with stun.fwdnet.net?

Also, where can I get information on provisioning?  These phones will  
be out of my hands soon and I'd like to be able to update the  
configs.  I saw a few utilities for generating the configs, but I'd  
like more specific info - I don't mind editing files by hand but want  
to know how it works. Does anyone have some resources?

thanks for all the help- this is a great list.
