how to run a bash script in irule (with a parameter to that bash script)?

However, how to launch that BASH script from the irule (and transfer the [TCP::local_port clientside] to that BASH script)?

is action on log (generating log using irule and then executing script using alertd) or icall usable?

by the way, why do you need to create a new virtual server? the irule should already be able to control traffic, shouldn't it?
