Application Redirection
Document ID: RDWR-ALOS-V2900_AG1302 465
3. Configure the application redirection filters. Once proxy IP addresses are established, configure
each application redirection filter (Filter 2 in this example) with the real server TCP or UDP port
to which redirected traffic will be sent. In this case, the requests are mapped to a different
destination port (8080). You must also enable proxies on the real servers:
Note: This configuration is not limited to the HTTP (Web) service. Other TCP/IP services can be
configured in a similar fashion. For example, if this had been a DNS redirect, rport would be sent
to well-known port 53 (or the service port you want to remap to). For a list of other well-known
services and ports, see the Well-Known Application Ports, page 175
.
4. Apply and save your changes.
5. Check server statistics to verify that traffic has been redirected based on filtering criteria.
Excluding Non-Cacheable Sites
Some sites provide content that is not well suited for redirection to cache servers. Such sites might
provide browser-based games or applications that keep real-time session information or
authenticate by client IP address.
To prevent such sites from being redirected to cache servers, create a filter that allows this specific
traffic to pass normally through Alteon. This filter must have a higher precedence (a lower filter
number) than the application redirection filter.
For example, if you want to prevent a popular Web-based game site on subnet 200.10.10.* from
being redirected, you could add the following to the previous example configuration:
>> # /cfg/slb/filt 2
(Select the menu for Filter 2)
>> Filter 2# rport 8080
(Set proxy redirection port)
>> Filter 2# /cfg/slb/real 1/adv/proxy enable
(Enable proxy on real servers)
>> Real server 1# /cfg/slb/real 2/adv/proxy
enable
(Enable proxy on real servers)
>> Real server 2# /cfg/slb/real 3/adv/proxy
enable
(Enable proxy on real servers)
>> # /info/slb/group <group number> /filter <filter number>
>> # /cfg/slb/filt 1
(Select the menu for Filter 1)
>> Filter 1# dip 200.10.10.0
(To the site's destination IP address)
>> Filter 1# dmask 255.255.255.0
(For entire subnet range)
>> Filter 1# sip any
(From any source IP address)
>> Filter 1# proto tcp
(For TCP traffic)
>> Filter 1# dport http
(To an HTTP destination port)
>> Filter 1# sport any
(From any source port)
>> Filter 1# action allow
(Allow matching traffic to pass)
>> Filter 1# ena
(Enable the filter)
>> Filter 1# /cfg/slb/port 5
(Select SLB Port 5)
>> SLB port 5# add 1
(Add the filter to Port 5)
