VPN Fragmentation MTU size

[w33mhz]

I have been tring to deal with some issues with my vpn going down, and I believe it has to do with it getting fragmented. So I lowered my mtu size on the remote asa to 1400, which seemed to be an acceptable value from testing. I was wondering should I set the mtu to 1400 as well on my local ASA?

Remote ASA 5505
IOS 8.4(2)8

Local ASA 5520
IOS 8.4(1)

Windows Haiku:

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

No, you shouldn't have to. They will negotiate 1400 or lower for MTU size since that is the maximum the remote ASA can transmit.
