The bind() call was added to support multiple IPs on a single Netrek server, and it wasn't in the code I wrote originally. The metaserver notes the IP address that the packet came from (in your case, the NAT external interface IP) and the name that is in the host name field (which comes from your server's .metaservers file). The relevant code is scan.c uread(). I don't believe the metaserver checks the IP address against the host name provided; it uses the IP address to merge further updates from the same server. The host name is what is sent out to a client request, either by TCP or UDP. The IP address is not sent. This is so that the server owner has full control over where clients are directed. The relevant code is disp_udp.c display_udp(). -- James Cameron mailto:quozl at us.netrek.org http://quozl.netrek.org/ _______________________________________________ vanilla-metaserver mailing list vanilla-metaserver at lists.real-time.com https://mailman.real-time.com/mailman/listinfo/vanilla-metaserver
