When giving out an ip address range for pptp connections, you could
specify a separate subnet and create rules for that.

$FW -A FORWARD -i ppp+ -s $PPTP_NET -j ACCEPT/REJECT/WHATEVER

and for your pppoe connection use ! $PPTP_NET ...

$FW -A FORWARD -i ppp+ -s ! $PPTP_NET -j ACCEPT/REJECT/WHATEVER
