Big-IP HA issue accessing management UI from a routed subnet

Firstly, you shouldn't manage the bigip's via the selfip's. You should be managing via the management interface IP's. That's what they're for.

Second. To start to find out why one doesn't respond, use tcpdump to verify whether it's the packets TO bigip that get lost, or packets from bigip back to the management station. That's probably the first step I'd perform to work out where things are going wrong.
