NimbostratusNeed help with Load Balancing iRule
Hi all, i have been working on this iRule to load balance traffic based on source ip addresses. Basically i wish to balance source traffic by throwing them to 2 of the proxy servers based on source ip addresses. i have came up with something listed below:
when CLIENT_ACCEPTED {
if { [IP::addr 10.0.0.1/32 equals 10.0.0.0/24] } {
pool Cache_Pool_HTTP member 5.5.5.5 80
}
else {
pool Cache_Pool_HTTP member 5.5.5.6 80
}
}
please advise if i am missing anything out here?

Hi Daniel,
If you change the IP::addr command to check the client IP address it should work fine to check if the client IP is in the 10.0.0.0/24 network:
if { [IP::addr [IP::client_addr] equals 10.0.0.0/24] } {
Aaron- hoolioOr are you trying to alternate between the two pool members based on the last octet of the client IP? If so, this might be relevant:

Check if client IP address is odd or even
if { [IP::addr [IP::client_addr] equals 0.0.0.0/1] } {
