pptp l2tp openvpn

hi

i wanted to have manage bandwidth on all type of vpn and i dont need to see content of vpn

for pptp, i found to have manage on 1723 tcp port.

for l2tp, on mangle , i found protocol, that have some kind of ipsec and GRE. another problem for this way is in every mangle you can put only 1 protocol, does it possible to put more than 1 protocol in 1 mangle rule?

for openvpn i found nothing.

can anybody help me for openvpn, and also say me the ways that i choose for pptp and l2tp are good or not, and if have better offer such as layer7 script, please say me.

thanks

For OpenVPN you specify port, which is used for tunnel 443 is by default,

/interface ovpn-server server print 
                     enabled: no
                        port: 443

thanks alot

can you please guide me more for pptp to write mangle configure on that and also for protocol for l2tp?

thanks
