Hi,

triyng to get  Grandstream GXP 2000 to work externally with my asterisk system. Looking at IP tables logs I can see my IP coming into the system on port 5060. My grandstream shows detected NAT type is port restricted cone when I specify my stun server.

sip_nat_conf is as below:

externip=81.136.41.51
localnet=192.168.1.0/255.255.255.0
nat=yes


Asterisk NOW version 1.7.1 and Grandstream is on latest firmware. To note I have had this extension working as a remote extension with 3CX with no issues so my firwall at home is ok.

on firewall at asterisk side, open these ports pointing to Asterisk server.

SIP: UDP 5060
RTP: 10000-20000

BTW: pls hide your Asterisk IP on the post, since this is not recommended for security.
