| Configuring the WSM using Device Manager |
The following table describes the types of URL-based Network Address Translation supported by WCR. For more information about NAT options, see Layer 4 Switching Filters--Filters fields.
No NAT
Traffic is redirected to the Web cache with the destination MAC address replaced by the MAC address of the cache. The destination IP address remains unchanged, and no modifications are made to the IP address or the MAC address of the source or origin server. This works well for transparent cache servers, which process traffic destined to their MAC address but with the IP address of some other device. For No NAT, choose Disabled in the Client Proxy field of the Filter dialog box.
Half NAT
The destination IP address is replaced by the IP address of the Web cache, and the destination MAC address is replaced by the MAC address of the Web cache. Both the IP address and the MAC address of the source remain unchanged. This is the type most commonly used. For Half NAT, choose Enabled in the Client Proxy field of the Filter dialog box.
Full NAT
The source IP address and the source MAC address are replaced by the IP address and MAC address of the Web cache. This method works well for proxy cache servers. For Full NAT, choose Enabled in the Client Proxy field of the Filter dialog box, and configure filtering on the SLB port.
