Is there any way we can change the TCP MSS size on the Juniper SA series appliances ?
Currently, I only see an option to change the MTU size, but there seems to be no way to tweak the MSS size, from the GUI.
Yes, even I don't see any option in GUI. By the way, why you want to change the MSS size?
no, this cannot be changed.
I have some weird performance problem when using ipsec tunnels, so it had been interesting to modify this value. But there is still no way to do it?
