FYI:RFC6598 for Carrier Grade NAT(CGN)/Large-scale NAT(LSN)

1. Brekeke Product Name and Version:
Brekeke SIP Server ver 3.3

It seems some carriers are using 100.64.0.0/10 for their NAT.
http://en.wikipedia.org/wiki/Carrier-grade_NAT
http://tools.ietf.org/rfc/rfc6598.txt

Since 100.64.0.0/10 is not private IP address (RFC1918), Brekeke SIP Server doesn't enable NAT-traversal and RTP-relay automatically even if SIP client is behind NAT.

For handling Shared Address Space 100.64.0.0/10 (RFC6598) with Brekeke SIP Server, set the following line in the [Configuration]->[Advanced] page.

net.internal-addr.pattern = ^100.6[4-9]|^100.[7-9][0-9]|^100.1[0-1][0-9]|^100.12[0-7]

FYI:

Brekeke SIP Server version 3.4 and later support RFC6598 without any additional settings.
