Remarks

This packet is sent to establish that the client supports UDP. In particular, when the client is using a non-standard port (e.g. not port 6112), this message is used to tell the server where it should send PKT_CONNTEST2 messages.

  • UDP Value is received from Battle.net in UINT32 3 of SID_AUTH_INFO, or UINT32 1 of SID_LOGONCHALLENGEEX.

This message should be sent in response to either SID_LOGONCHALLENGEEX or SID_AUTH_INFO.
