I have l2tp server (rb450g v4.1), and client (rb400 v3.30).
I have configured l2tp with bridge. Strange thing is that when i get 2.5+2 mbit trafic passing tunnel, procesor ussage is 100% on both ends. Bur i can run bandwidth test 40 megs full duplex and it works fine, but cpu again is 100%. Can there be possibility that cpu is showing wrong?
And how can i optimize l2tp? Any tips?
