Most PPPoE systems use a MTU of 1492, which would be the proper setup. PPP is compressed from IP and your adding far more overhead with IPSec that is encrypted. The combination will cause a very large overhead on any VPN traffic, I would suggest use of possibly a P2 while using both if there is much traffic on a VPN. I think several people did some testing on PPPoE connections and found that it "ideally" took a p-166 to achieve maximum bandwidth potential without the Ipsec overhead. You wouldn't see this load under a non-pppoe connection running ipsec, which verifies your experience with your other VPN nodes.
