It appears that the Clientless VPN (SSL) function completely ignores the mtu setting that is applied to the inside and outside interfaces.
mtu inside 1300
mtu outside 1300
I have verified that this is true with ver 7.2(4) and 8.0(3) using packet captures at the client side of the session.
I have confirmed that if the Clientless VPN (SSL) function would adhere to this setting, all of the problems that our users are experiencing when accessing OWA remotely would go away.
I've verified this by manually setting the MTU size on the workstation. When it is 1300, everthing works fine.
Can anyone explain why the Clientless VPN (SSL) function will not adhere to this setting?
