(es) As mentioned earlier, UDP broadcasts are not forwarded across interfaces. To resolve this problem we can use a PERL script found here. This script requires NetPacket::IP, NetPacket::UDP and a modified version of the Net::Divert module which can be found here until the author integrates these changes into the official distribution. The script listens for packets on a specified port and upon receiving them, rewrites the destination field in the packet's header and then sends a copy to all of the hosts in a list. To figure out what IP to add to the list of recipients, we have to find out what IP the game uses to announce itself. Since this is what we did when setting up routing, we can just refer to that data. Note that all players should be added in this file independent of whether they needed static routes or not. In addition to executing the script, we also have to add ipfw rules to forward broadcasts that we receive from the VPN clients to our script.
