Do I need iRule to redirect outbound traffic

Hi GIP,

You could create a new pool containing the network device for ISP2 and then use a rule on your wildcard virtual server to do this.

Here's an example that should get you started:

when CLIENT_ACCEPTED {
   if {[IP::addr "[IP::client_addr]/24" equals "10.20.30.0"]} { 
      pool isp2_pool
   }
   else {
      pool default_gateway_pool
   }
}

Try checking the wiki for details on the IP::addr command for comparing IP's and/or subnets (Click here)
