How to config PBR

Hi Sumanta, I changed it a bit and added comments:

rule pbr-rule {
when CLIENT_ACCEPTED {
    log local0. "PBR iRule starting"
     client IP is from subnet_bypass and will be forwarded via pool_hop_1
    if {[class match -- [IP::client_addr] equals subnet_bypass]} {
         if pool_hop_1 has no members, connections will be forwarded according to routing table
        if { [active_members pool_hop_1] < 1 } { 
            log local0. "No active pool members so will forward to next-hop"
            forward
         if pool_hop_1 has available members, connections will be forwarded via pool_hop_1
        } else {
            pool pool_hop_1
        }
     client IP is from subnet_permit and will be forwarded via WHTTP_Transparent
    } elseif {[class match -- [IP::client_addr] equals subnet_permit]} {
        pool WHTTP_Transparent
        log local0. "PBR successful"
    }
}
}

Thanks, Stephan
