Disable RFC1644 and RFC1323 negotiation.  The pppd of your service
provider can't handle it.  From /etc/netstart:

if [ -n "$tcp_extensions" -a "x$tcp_extensions" = "xNO" ] ; then
        sysctl -w net.inet.tcp.rfc1323=0
        sysctl -w net.inet.tcp.rfc1644=0
fi

You can just set the tcp_extensions sysconfig variable appropriately.
