[Serusers] Grandstream 486 using NAT/Stun talking to Ser

[Sean Lowry]

Hi all,

i had the issue yesterday were the grandstream wouldn't register with ser
using auth digest. 
i've updated the firmware on the grandstream and it still wont register
using auth digest in nat mode but when i use non nat it registers just fine.

could this be an issue with the Stun which grandstream use to do nat??

has anyone had any problems like this.

Sean
