Speedfusion and differing MTUs

Just a quick question for the experts out there. T-Mobile offers me a 1500 MTU while AT&T gives me 1430. When using speedfusion, is it best to lower them both to 1430 or leave them mismatched?

You can leave them mismatched. SpeedFusion tunnel will do MSS clamping for TCP connection using the smallest MTU size across all the WANs.


Thank you!!! For both the answer and writing a great product!
