iRules and source IPs - GTM

You can make use of netmasks or netmask shorthand notations in your address comparisons.

Something like this should work

if {[IP::addr [IP::remote_addr]/24 equals "172.19.10.0"]} {
  LB:reselect snat none
}

This will compare the address in IP::remote_addr to see if it is in the 172.19.10.* network.

If you want to do something like "if addr greater than addr1 and less than addr2) then you'll probably have to do the math to convert the ip address to it's number equivalent and then do the math comparisons.
