crypto boost-tcp: how to use it

With ZLD 5.10 some "boost" of IPsec VPN was delivered to device which had it. So no USG40, USG40W, USG60, USG60W currently, but for USG20-VPN and USG20W-VPN.

How to sensefully use it?
  • Is it useful enable it on only one endpoint if the other one is not capable? Example: USG40 on client side, USG20-VPN on the server side, enable it only on server side could be useful?
  • Is it useful enable it the device is an L2TP server for roadwarriors connections?
Thanks for your time.

    It looks only supprot in 5.10 firmware. The other models without 5.10 version.
    In Site-to-Site scenario, of cause it has to apply in both of devices.
    This command should works in all of VPN tunnel.(Not only site to site VPN)

    Thanks @CHS, i had the same impression. But I'd love a statement from Zyxel representatives.
