VPN Howto: Linksys + DD-WRT + PPTP + Mac OS X Client
The PPTP Server is now configured. However, we need to create a startup script to overwrite one of the PPTP config files.
3) Click on
Administration,
Diagnostics. In the
Commands text area, paste the following script:
echo 'lock' > /tmp/pptpd/options.pptpd
echo 'name *' >> /tmp/pptpd/options.pptpd
echo 'proxyarp' >> /tmp/pptpd/options.pptpd
echo 'ipcp-accept-local' >> /tmp/pptpd/options.pptpd
echo 'ipcp-accept-remote' >> /tmp/pptpd/options.pptpd
echo 'lcp-echo-failure 3' >> /tmp/pptpd/options.pptpd
echo 'lcp-echo-interval 5' >> /tmp/pptpd/options.pptpd
echo 'deflate 0' >> /tmp/pptpd/options.pptpd
echo 'auth' >> /tmp/pptpd/options.pptpd
echo '-chap' >> /tmp/pptpd/options.pptpd
echo '-mschap' >> /tmp/pptpd/options.pptpd
echo '+mschap-v2' >> /tmp/pptpd/options.pptpd
echo 'mppe required' >> /tmp/pptpd/options.pptpd #this line forces encryption and fixes OS X
echo 'mppe stateless' >> /tmp/pptpd/options.pptpd
echo 'mppc' >> /tmp/pptpd/options.pptpd
echo 'ms-ignore-domain' >> /tmp/pptpd/options.pptpd
echo 'chap-secrets /tmp/pptpd/chap-secrets' >> /tmp/pptpd/options.pptpd
echo 'ip-up-script /tmp/pptpd/ip-up' >> /tmp/pptpd/options.pptpd
echo 'ip-down-script /tmp/pptpd/ip-down' >> /tmp/pptpd/options.pptpd
echo 'ms-dns 192.168.1.1' >> /tmp/pptpd/options.pptpd #enter your router's ip here
echo 'mtu 1450' >> /tmp/pptpd/options.pptpd
echo 'mru 1450' >> /tmp/pptpd/options.pptpd
Make sure to replace "192.168.1.1" with your the LAN IP of your router, if it's different. Click
Save Startup. The router is configured, let's setup the VPN connection in OS X.
