3DES and MTU size

What should I adjust my MTU size when using 3DES and on what interface?

Thank you,

Re: 3DES and MTU size

Normally, there should be no need to adjust your MTU. The system that is responsible for encapsulating data into IPsec will fragment the data as needed.

The maximum IP mtu size for data that's encapsulated in IPsec is 1500 - (18 + 20 + 8) = 1454 bytes.

When using application that require DF, you must not exceed this value.

Regards,

Leo
