Free-Metric with Basic FWLB
This example uses the basic FWLB network as illustrated in
Figure 113 - Basic FWLB Network, page
Figure 113: Basic FWLB Network
To configure free-metric FWLB in a basic network
1. On the clean-side Alteon, enable RTS on the ports attached to the firewalls (Ports 2 and 3).
Enable filter and server processing on ports 2 and 3 so that the responses from the real server
are looked-up in the session table.
2. On the clean-side Alteon, remove the redirection filter from the ports attached to the real
servers (Ports 4 and 5), but ensure that filter processing is enabled.
The redirection filter is removed so that the return packet traverses through the same firewall. If
the firewalls synchronize their states, then it is not required to remove the redirection filter.
Filter processing is enabled to make use of the RTS-created sessions.
Use the hash metric if the session is from an FTP or RTSP servers.
3. On the dirty-side Alteon, set the FWLB metric.
>> # /cfg/slb/port 2/rts enable
>> # /cfg/slb/port 3/rts enable
>> # /cfg/slb/port 4/rem 2048
>> # filt ena
>> # /cfg/slb/port 5/rem 2048
>> # filt ena
>> # /cfg/slb/group 1
>> # metric <metric type>
