IPv6 support for TCP Port Mapper

by Vitaly, Friday, June 26th, 2015

TCP Port Mapper 1.70 released.

Now IPv6 addresses can be used in all settings: ListenIP, MapToHost, MapArray, MapFromFile, MapFromUrl etc.

It is preferred to enter IPv6 addresses, enclosed in square brackets. That allows to extract the Port from the IPv6:Port.
Example of the IPv6 address: [2001:4860:4860::8888].

If the ListenIP setting is not specified (or ListenIP=ANY) you can set SrvIPv6=Yes.
That allows to force listening incoming IPv6 connections.

If the both IPv4 and IPv6 addresses are exist for the destination host, TCP Port Mapper will use IPv4 address. To force using IPv6 address you can set: CntIPv6=Yes.
