Behind NAT
 Behind NAT: If your EZLoop® IP-PBX Enterprise SIP Server is behind NAT, we
strongly suggest u to enable Behind NAT to avoid some unexpected issue, such as
“one way voice”.
 External IP: If you input External IP, EZLoop® IP-PBX Enterprise SIP Server will take
that IP address as its argument. If EZLoop® IP-PBX Enterprise SIP Server is behind
NAT, the SIP header will normally use the private IP address assigned to the server.
The remote device will not know how to route back to this address; thus, it must be
replaced with a valid, routable address.
 External Host: External Host takes a fully qualified domain name as its argument. If
EZLoop® IP-PBX Enterprise SIP Server is behind NAT, the SIP header will normally
use the private IP address assigned to the server. If you set this option, EZLoop® IP-
PBX Enterprise SIP Server will perform periodic DNS lookups on the hostname and
replace the private IP address with the IP address returned from the DNS lookup.
Note:
•
You should not set both of External IP and External Host together; otherwise
there will be some unexpected problems appeared. That means you can only
chose one for External IP or External Host for “Behind NAT”
 Local Net: Local Net is used to tell EZLoop® IP-PBX Enterprise SIP Server which IP
addresses are considered local. If one of caller or callee is not under Local Net,
EZLoop® IP-PBX Enterprise SIP Server will set the address in the SIP header that
can be translated to that specified by External IP or the IP address can be looked up
with External Host. The format will be IP/ Subnet Mask. Example: 192.168.1.0/
255.255.255.0
