I have this situation where the source IPs change on a wireless mesh. I want fair nat. I found the fairnat script and have been reading the lartc howto, but am not sure how to proceed. (fairnat at http://www.metamorpher.de/fairnat/) I want everyone to burst to (almost, a specified percentage like 90%) full, but when all IPs are on, to share fairly irrespective of number of connections. The IPs change dynamically. If the user doesn't know why their P2P or download manager is slowing them down, their problem. They can run whatever they want. I just don't want one user to flood out the rest, and there should be a little spare so it doesn't take time to correct for light users. Oh, and upload limiting (also fairly) for the lot would be good, as this rate is limited, e.g. 512 down and 128 up. And it is running on freifunk on a Linksys WRT 54 GL, so performance might be an issue on the 200Mhz processor. At the moment freifunk comes with ingress (by internal destination IP) limiting quite nicely. The number of clients is expected to be 0 to 64. I can deal with large numbers of clients later, if it ever happens. cheers, Jan -- .~. /V\ Jan Groenewald /( )\ www.aims.ac.za ^^-^^ _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
