IP Proxy Addresses for NAT
Transparent proxies provide the benefits listed below when used with application redirection.
Application redirection is automatically enabled when a filter with the redir action is applied
on a port.
n With proxies IP addresses configured on redirected ports, the Web switch can redirect cli-
ent requests to servers located on any subnet, anywhere.
n The Web switch can perform transparent substitution for all source and destination
addresses, including destination port remapping. This provides support for comprehen-
sive, fully-transparent proxies. These proxies are transparent to the user. No additional cli-
ent configuration is needed.
The following procedure can be used for configuring proxy IP addresses:
1. Add proxy IP addresses to the redirection ports.
Each of the ports using redirection filters require proxy IP addresses to be configured. Each
proxy IP address must be unique on your network. These are configured as follows:
2. If VMA is enabled, add proxy IP addresses for all other switch ports (except port 9).
Virtual Matrix Architecture (VMA) is normally enabled on the Web switch. In addition to
enhanced resource management, this feature eliminates many of the restrictions found in ear-
lier versions of the Web OS. It does require, however, that when any switch port is configured
with an IP proxy address, all ports must be configured with IP proxy addresses. Otherwise, if
VMA is disabled, only the client port with filters need proxy IP addresses and this step can be
skipped.
