The default is not a restriction, but meant for good performance: it is 9216, which is the maximum MTU for any supported network interface. If you use something bigger, you get way worse performance (up to and including 0 bits per second) if the network is a bit busy, drops some packets, etc. Segher _______________________________________________ cfarm-users mailing list cfarm-users@lists.tetaneutral.net https://lists.tetaneutral.net/listinfo/cfarm-users
