Re: [Config] QOS for Cisco 800 w/ Dialer interfaces using NBAR
ok just to make sure, E0 Outbound is leaving the router towards the LAN.
NBAR is always on. The ip nbar pro allows you to do sh ip nbar protocol-disvovery.
The way you have configured the class automatically states to use NBAR.
I would also suggest to create a THIN-2... here's why, Dialer outbound is leaving the rooter to the net and E0 outbound is leaving the roooter to the LAN... so I would separate their Policy |

| Yes, e0 outbound goes to the LAN behind the router, the "RDP clients". I have protocol discovery turned on for the e0 and di1 interfaces just to confirm the direction of the traffic, but it doesn't make sense to me. If an RDP client behind these 837/877's has RDP traffic coming inbound from my LNS. Shouldn't the RDP traffic go inbound on Dialer1 and outbound on Ethernet0? SNMP stats show this pattern but NBAR does not, which is why I am thinking I am doing something wrong. |

| Notice how the diealer1-rdp-input doesn't come anywhere near to matching the number of ethernet0-rdp-output.(or not at all)
