I've tried to "analyze" the packet and it looks valid to me. Since I am a complete noob at it right now I might have failed. However here are my results:

Flags: D0 => MSG_APPENDED_ACKS|MSG_RELIABLE|MSG_ZEROCODED
Sequence: 00 00 04 0B => 1035
Extra: 00
PacketID: FF FF 00 D8 => ParcelAccessListReply/Low
DataBlock

UInt32 Flags: 01 00 00 00 => 1
Int32 LocalID: E2 01 00 00 => 482
