MTU - After some information
Just a quick query regarding MTU size. Our new site is due to go live in a few weeks, and we've setup a S2S VPN Connection. The new site is due to have Sun Ray terminals connecting back to the main site into a Sun Ray Server and ESX Server.
We've tested the Sun Rays at home, now obviously our internet connections at home aren't that great, so we've been following advise on setting MTU limits to what the WAN link can handle.
Currently 1391 is a safe MTU and no fragmentation on the packet, obviously the new site will have a similar MTU.
If we set both VPN Routers at a MTU transmit max of say 1300, what happens to our current infrastructure that still runs at 1500 MTU. All our local machines, servers all have a default of 1500.
Anyone have suggestions or ideas or a decent explaination?
