I have a several user in net-group, suppose 192.168.2.2 through 192.168.2.15

Is there any possibility to make using of web-proxy compulsory only for concrete user - examp: only 192.168.2.4 and 192.168.2.11 must pass through proxy to access internet, all other user must have direct access through router.

thank you in advance

Yes, you can limit as ip. just go to the ip - web proxy. go to the tab access and define which source addr u want to limit and the others are limit to cache.

The rule is :
1. limit the source addr , ex:2.4 and 2.11 -- allow
2. the net, ex 192.168.2.0/24 -- deny


Thx,
