Did this really apply to all operating systems and all versions of Linux? We had a discussion about it when the IPv6 support was added, but I don't remember all the details - but something with the mapping was O/S and sysctl dependent.

> When udpbindaddr=:: is set Asterisk accepts IPv4 and IPv6 clients both stored in a struct sockaddr_in6 with AF_INET6 family type. Current NAT code for IPv4 checks if the socket type is AF_INET6 and thus fails to handle IPv4 mapped addresses properly. The patch adds an additional check for this case allowing IPv4 clients to be handled by NAT even when IPv6 is enabled.
