The iRule 'forward' command does not result in connections being routed to the proper destination if the virtual server has an attached pool.


Connections are routed to pool member instead of destination determined by network routes.


Virtual server with: - Pool. - iRule that issues 'forward' commands.


Remove pool assigned to virtual server and select the pool using an iRule with a 'pool' command when 'forward' command is not issued.
