3. Enable filter on server port 1.
Filter is enabled on port 1, because you want Alteon to look up the session table for the
transparent load balancing entry.
4. Enable server processing on port 1.
5. Configure an allow filter for health checks to occur.
If you have enabled link load balancing filter and server processing on the same port, then an
allow filter must be configured for health checks. The allow filter is activated before the link load
balancing filter, so that the health check traffic does not get redirected to the WAN links.
For more information on health checking, see
Health Checks for Real Servers, page 176
.
6. Add the allow filter 50 to port 1.
Note:
If you are using two Alteons for redundancy, then must add allow filters for VRRP before the
redirection filter. For more information on VRRP, see
