    if { [IP::addr [IP::client_addr] equals 10.10.10.0/24] }
  • string multiple comparisons using elseif

Thanks Amy. Is Data Group option available in GTM? just realized that end servers are spread across in 2 different data centers, so i would need to configure wide IP list and assign LTMs VIP as virtual servers. In this case, I would require an Irule in GTM to filter the source traffic?? will this work??
