In the CHAP-Secrets section, enter a list of username/password combinations in the following file format:Īlso, note that the root username/password is also allowed to connect via PPTP. In the Client IP(s) section, enter a range of one or more IP addresses that do not overlap with the DHCP address range. In the PPTP section, enter the LAN address of your router (probably 192.168.1.1). Now that we have enabled the PPTP server, we must configure it.ģ) Click on Administration, Services. The complete steps follow.ġ) Install the most recent version of the dd-wrt firmware for your router.Ģ) Click on Administration, Services. The easiest way to do this is to create a startup script that overwrites the default PPTP config. Instead of disabling encryption altogether, we need to change DD-WRT's PPTP config to force encryption. The problem is that OS X's pppd will fail on encryption negotiation unless the server requires encryption. DD-WRT's default PPTP config enables encryption but does not force it.

We used Mac OS X Tiger 10.4.6 and a Linksys WRT54GL running DD-WRT v23 SP1, but these steps should work with any router running DD-WRT.įollowing the guides we've found will result in Internet Connect aborting with the error, 'Could not negotiate a connection with the remote PPP server'. So we couldn't find any documentation on getting a Mac OS X VPN client to connect to our Linksys router using PPTP, so we thought we'd post a short guide.
