No, particularly if they're on the same network! TTL = "Time To Live" - the number of router hops a packet can make before it's dropped (this prevents routing loops slowly accumulating packets). Your installation ought to "just work" out of the box; if you're not sure what a particular network parameter does things might start misbehaving if you change it at random. I'm not saying I don't advocate experimentation; you just might not want it on a production network. If you're interested in learning more then vol. 1 of "TCP/IP Illustrated" by (the late) WRS is well worth a look. That and continued questions here - they seem like a friendly bunch! -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287163 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk Semantic rules, OK?
