[Asterisk-Users] SMC and Grandstream

[Didelot Loic]

After 3 days of chat and many hours of GOOGLE I finaly disturb you to
get some help.

I have an SMC7404WBRA NAT-Boradband router and a Grandstream
Budgettone100. I did the latest firmware upgrades.

I can register and phone using fwd, sipgate and of course my * if I put
the phones-ip on the only DMZ I have on the router.

But Im not even able to register with my * when the phone is not on the
DMZ. I tried Portworwarding - Stun etc....  but nothing works.

Maybe I could get some help here.

Thanks in advance,
Didelot loic.
