PPTP Server

Hello all,
I currently have a PPTP server setup on one of my Mikrotiks. This is how I get into all of my network devices from home. I have recently setup a load balance box for a customer and connected it to the mikrotik. This box has a /30 ip address that resides on the Mikrotik. I am trying to remotely manage this box but I cannot ping it from my cpu. I can ping the first ip address of the /30. That is on the bridge int, but I cannot ping the second ip adress. I cannot even ping it from the Mikrotik. I was just wandering if there were any rules needed to setup to all my connection. Thanks
