Configuring service groups on the WCCP device
WCCP uses service groups to specify the traffic that is redirected to Content Gateway (and other devices).
- A service group can intercept one or more protocols on one or more ports.
- Service groups are assigned a unique integer identifier (ID) from 0 to 255.
- Service groups IDs are user defined; they do not have a default port or traffic type.
The following table illustrates a set of service group definitions that are often found in networks. If you are configuring for IP spoofing, see the table in Content Gateway IP spoofing for common reverse service group IDs.
Service ID | Port | Traffic Type |
---|---|---|
0 | 80 | HTTP |
5 | 21 | FTP |
70 | 443 | HTTPS (when HTTPS support is enabled) |
Service groups must be configured on the router and in Content Gateway.
The best practice is to configure the routers first and Content Gateway second.
Follow the instructions in your router documentation for specifics, but in general:
