I have a Cisco 877 router as an internet gateway.
I have a very low link to the internet (about 1Mbps in down) and I would like to make QoS on my 877 to prioritize my VPNs (UDP 500, ESP... or if it is more easy in entering several public ip) in telling by example :
VPNs => 80% bandwidth
Internet => 20% bandwidth
I tried to find solution on net but I'm a bit lost so if someone could help me, that would be great.
