These lines right here indicate that it detected the addresses you 
defined and would be using them.

That is much of the reason for serverpool.cpp's existence, to restrict 
MythTV's unprotected server ports from listening on "unsafe" addresses. 
Generally the autoconfigured IP addresses never get routed to the 
internet, and anything listening on them would only be accessible 
through the local network.

The option in mythtv-setup is only available in 0.26 and later. Current 
versions of 0.25 will obey the setting, but it is not configurable 
through the GUI. Either update to 0.26, or disable it manually in the 
database.

INSERT INTO settings (value, data, hostname) VALUES ('AllowLinkLocal', 
0, <your hostname>);
