RFC879> HOSTS MUST NOT SEND DATAGRAMS LARGER THAN 576 OCTETS UNLESS THEY RFC879> HAVE SPECIFIC KNOWLEDGE THAT THE DESTINATION HOST IS PREPARED TO RFC879> ACCEPT LARGER DATAGRAMS. RFC879> RFC879> This is a long established rule. http://www.ietf.org/rfc/rfc0879.txt?number=879 I agree, the best MTU is the largest possible without fragmentation, which depends on your ISP and all other routers between yourself and the other host. For example, between my PC at work and www.mit.edu it is 1500. My answer to your original email was saying that a lot of dialup ISPs have a max MTU of 576 and maybe some DSL connections as well. Anyway, here is some interesting info about finding your personal max MTU: http://www.internetweekly.org/llarrow/mtumss.html http://members.tripod.com/~EasyMTU/easymtu/findmtu.html and some related tweaking info about Receive Window size for the curious among you. http://www.dslreports.com/tweaks/RWIN Ben _______________________________________________ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:[EMAIL PROTECTED]
