7/9/2002 IpDrv.dll for Unreal Tournament version 436
====================================================
This is a replacement IpDrv.dll to fix the Denial of Service attack
bug described here:
http://online.securityfocus.com/archive/1/280544
It also fixes a Windows 2000+ server problem where server lag gradually
increases over time.
Both problems are caused by incorrect handling of ICMP port unreachable
messages. When a server running the replacement IpDrv.dll sees an ICMP
port unreachable message, it removes that IP/port from its list of clients
and no longer attempts any communication with that IP/port pair.
