Bandwidth Control to Specific Internet Sites

[mark_f1man]

Is it possible to setup a bandwidth restriction to specific internet sites?
eg. thinking of sites such as Youtube, Facebook, Twitter etc

I tried to setup an example with
- scheduling set to first matching rule
- a restriction of 512kb/s
- a rule set with source = any
- destination = (for example) 60.234.81.0, 255.255.255.0 (appears to be youtube caching)
- port = any
- protocol = all
- control max tcp window = checked
- apply to induced traffic = checked
- apply to traffic to/from the local machine = checked

This seemed to work to a fashion with NAT traffic, although I wasn't get anywhere near the restricted speed. And didn't appear to work with proxy traffic. I checked using the youtube speed info screen which shows your "streaming speed"

1. Should this work with both NAT and Proxy traffic?
2. Are the above settings optimal or should I change some of them?

In the bandwidth control rule that you set up for this, under the Source / Destination tab, is "Rule is bi-directional" checked?

[mark_f1man]

Yes sorry ommitted those details

- rule is bi-directional (Source <-> Destination) = checked
- Allow different restriction to be applied for reverse traffic = unchecked
- Wingate version 6.6.4
- No plug-ins
- intercept connections made via ENS... = checked on standard services

edit:
- Windows Server 2003
- single NIC

1. Should this work with both NAT and Proxy traffic?

Bandwidth Control works in the ENS driver, and I notice that when a client computer has been manually configured to use the proxy server, it bypasses the ENS driver (a NAT connection isn't made to youtube by the client) and bandwidth control doesn't get applied.

If you're able to, setup the WWW Proxy to intercept port 80 from the ENS driver, and then remove the proxy config from the clients. This will make the clients try to connect to youtube (or whatever other service you want to control) through NAT, but the connection will be redirected through the proxy anyway. The important thing here is that the connection does go through the ENS driver where bandwidth control can work it's magic.

2. Are the above settings optimal or should I change some of them?

They look fine to me. If bandwidth control worked like you expected when using NAT, then it should still work through an intercepted proxy.
