Change the first ms-dns to 172.16.0.23, it will be OK.

echo "ms-dns 208.67.222.222" >> /etc/ppp/options.pptpd

echo "ms-dns 8.8.8.8" >> /etc/ppp/options.pptpd

echo "ms-dns 172.16.0.23" >> /etc/ppp/options.pptpd
echo "ms-dns 8.8.8.8" >> /etc/ppp/options.pptpd

For x86_64 platform. there will be "pptpd: unrecognized service" error message.
Replace the pptpd package with pptpd-1.3.4-2.el6.x86_64.rpm, will resolve it.

wget http://yinhm.github.com/downloads/pptpd-1.3.4-1.amzn1.src.rpm

wget http://poptop.sourceforge.net/yum/stable/rhel6Server/x86_64/pptpd-1.3.4-2.el6.x86_64.rpm

rpmbuild --rebuild pptpd-1.3.4-1.amzn1.src.rpm

rpm -i ../rpmbuild/RPMS/i386/pptpd-1.3.4-1.*.i386.rpm

rpm -ivh pptpd-1.3.4-2.el6.x86_64.rpm
