issues, is to add "ip tcp adjust-mss blah" if cisco kit on a 'central-ish'

the MSS option in the TCP packet to force both ends of the conversation to use
lower size packets. Thereby negating the deal to modify MTU on kit you may/may
not manage inbetween.</FONT></SPAN></DIV>

so, please contact me off-list – As far as I’m concerned, M2’s response of ‘get
your customers to change the MTU on their routers down to 1400’ really isn’t
acceptable and this apparently has been on-going since Thursday. (SSL
based websites in particular, banking websites – we’ve had reports of clients
unable to access/successfully log in to almost every major bank in Australia so
far)<o:p></o:p></SPAN></P>
