iRule to forward traffic depending on specific IP to original pool when holding pool enabled.

your scenario is strange....

holding pool with 2 members --> default pool holding pool with 1 members --> holding pool

most of customer want to disable holding pool if less than 2 members are up.

I never used

ne

when CLIENT_ACCEPTED {
    set default_pool [LB::server pool]
    set holding_pool Holding_$default_pool
    if { ([active_members $holding_pool] >= 2) && !([class match [IP::remote_addr] equals Internal_ip]) } {  
        pool $default_pool
    } else {
        pool $holding_pool
    }
}
