NimbostratusIrule for restricting selected ips for NOT USING TLSV1 and 1.1
Hello All,
I have requirement of use an iRules in F5 to enable TLS V1.0 and 1.1 only for Selected IP addresses or IP ranges. and enable only TLS 1.2 for all remaining .
I have tried the irule below...
matchclass ...
Note: matchclass has been deprecated in v10 in favor of the new commands. The class command offers better functionality and performance than matchclass.
Inserting the appropriate class command into this iRule would look something like this:
when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals TLSV1.0_1.1_Enable ]} { SSL::profile example_profile_enable_weak_TLS } else { SSL::profile example_profile_disable_weak_TLS } }

NimbostratusLooks like the syntax may be slightly off. Try this:
{ if { [matchclass [IP::client_addr] contains TLSV1.0_1.1_Disable ]}Check the following solution article for examples on referencing data groups in IRules:
vvskaladhar_488Thanks you so much for the help on this. i am able to add the irule as below and waiting for the confirmation form the client to say ready for testing. below is the irule by taging to the vip kaladhar.abc.com.
when CLIENT_ACCEPTED {
if { [matchclass [IP::client_addr] contains TLSV1.0_1.1_Disable ]} {
SSL::profile kaladhar.abc.com_TLS_Disable} else {
SSL::profile kaladhar.abc.com}
