pptp secrets on rb1100

PLEASE HELP…
I use a ppp secrets (pptp and l2t) for connecting from home. I have at work rb1100 (replacing the rb750).
the configuration of them worked on the rb750. but now something is missing:
I can connect with the user name as pptp vpn to the rb1100, also I can ping my default route (192.168.0.254) but I can’t ping any static ip on the net.
why?

Did you set the arp to proxy-arp as per the instructions? I install a route in the client computer/router instead, but either work.
