That's fine for > theory. It works okay in practice, too. You are correct about misconfigured networks. In my experience, the only reason to ever reduce the MTU is to work around a problem discovered in someone else's network (not my local segment). Fixing the problem by getting someone else to fix their network is generally too hard. If MTU == MRU was forced behavior, the viability of this workaround would be removed, one less tool in the toolbag, so to speak. - -- David DeSimone == Network Admin == fox@verio.net "It took me fifteen years to discover that I had no talent for writing, but I couldn't give it up because by that time I was too famous. -- Robert Benchley -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGojYwFSrKRjX5eCoRAipgAJkBV6/IhmR8M+0o/bHviMFEvrfovQCcDP3w FoLZrDFkw5bJKqIwiLaW62E= =0KSA -----END PGP SIGNATURE-----
