What would happen if the OpenVPN client is actually a router that forward
trafic from a network ? In that case, only the dynamic TCP MSS clamping can
work.
The same if your OpenVPN server is not the end server you communicate with.
The only case what you suggest might work is if the OpenVPN client *is* the
application client and the OpenVPN server *is* the application server. In that
case it would be enough that the tun or tap interface presents a MTU which
takes in account OpenVPN header overhead.
In my use cases, this nevers happens.
Yes, i'm using http server on vpn server and wget on vpn client.
