Create IP type LTM data-group. Define allowed IP/subnet values, and add optional descriptions. You can find data-group creation page at
. Example of an IP type data-group in CLI/TEXT format:Local Traffic - iRules - Data-group List
ltm data-group internal datagroup_allowed_ip { records { 100.20.20.0/32 { } 199.20.20.128/25 { } } type ip }
Create an iRule that checks for matches against entries in datagroup_allowed_ip
when CLIENT_ACCEPTED { if { [class match [IP::client_addr] eq "datagroup_allowed_ip" ] }{ Traffic is allowed. Client IP match found in datagroup_allowed_ip return } else { Traffic is dropped. Client IP match not found in datagroup_allowed_ip drop } }
