Description

The calls to JoinMulticastGroup and LeaveMulticastGroup on FSocket do not allow for the interface address to be passed in, only the the group address. The interface address is currently hard-coded to INADDR_ANY, which may not select the correct interface in a multiple adapter setup.

Have Comments or More Details?
