Yes, I see the same server-side BCP failure over PPTP. Client-side BCP OK on 6.13, but server-side BCP did not work at 6.13 and required to be down-graded to 6.12.on the L2TP-Server side the packets are not bridged anymore. Downgrade to 6.12 fixed it.
Will this update include a fix for Ticket#2011122766000641, concerning packet loss if PPP packets arrive out of order?What's new in 6.8rc1 (2014-Jan-02 09:46):
*) improved speed of PPP, PPPoE, PPTP & L2TP on multicore routers
