Hello, we are deploying Cisco 871 routers to our customers, we do a simple IPSEC point to point VPN connection. We want to ensure the VoIP traffic is granted over the data traffic.
I did this config but I don't know if I'm doing it right, because I think you have to do an special configuration to make QoS work under IPSEC VPN.
Code:
policy-map policy1
class voice
priority percent 75
class default-traffic
bandwidth percent 25
random-detect
--------------------------------
interface Vlan1
ip address 192.169.15.100 255.255.255.0
no ip redirects
no ip proxy-arp
ip nat inside
ip virtual-reassembly
Is it right ?

Hi,
There are some questions left before one can tell, if your config is right. I can tell right away that it is not copmplete, but some parts are missing.
First, how did you define the classes "voice" and "default-traffic"? Could you provide the "class-map" commands configured? Unless the class-maps describe traffic properly your policy will not work as expected.
Second, where do you apply the QoS policy? In order to apply the policy you must configure "service-policy output policy1" at the interface, which might be congested.
Third, what is your network situation, i.e. how are the routers connetced to the LAN and to the internet? Which LAN switch are you using? Did you configure QoS there?
So in brief, the configuration excerpt you posted is not doing any QoS, nor is it complete. Could you please provide the rest of the configuration and also a bit more info on your setup? Then we can assist you effectively.
Regards,
Martin

You need to post the complete configurations. You can find some good examples on this page:
