Trebam pomoc oko podesavanja QoS na Cisco ASA 5505. Imam Cisco ASA5505 koja radi kao Cisco Easy VPN client (mod network extension). Link ka ISP-u je 6/6 Mbps. Htio bih da kontrolisem raspodjelu bandwitha u oba smjera (download/upload) na nacin da ogranicim ne-vpn saobracaj na maksimalno 1 Mbps (upload 1Mbit i download 1 Mbit) a da VPN saobracaj zauzme ostalih 5Mbit-a bandwidth-a. Naravno, ukoliko nema ne-vpn saobracaja vpn saobracaj bi trebalo da ima na raspolaganju cjelokupan bandwidth. Napravio sam konfiguraciju u kojoj sam koristio traffic policing (koristio sam policing je nemam ideju kako bi sa trafic shapingom mogao regulisati download i upload zasebno) i postavio vrijednosti na koje bih da ogranicim saobracaj. Problem se javlja jer je sav saobracaj ogranicen na 1Mbit sto ce reci da nisam dobro klasifikovao VPN saobracaj (ili bar ja tako mislim). Za klasifikaciju VPN saobracaja sam koristio access liste jer zbog Easy VPN-a ne mogu koristiti komandu match tunnel-group. U prilogu je konfiguracija ASE pa ako neko ima ideju ili ako vidi gdje grijesim neka napise.
Jos da dodam, a mozda moze biti korisno da se koristi AES256 enkripcija, IPSec protocol (esp)...
