Question

Almost got VPN to work, but Auth failing?

Hi,

I almost got VPN to work, but I have one last error. Here is, what I did so far:

1.) Configured VPN via Server app

2.) Enabled PPTP like described in Apple support doc

3.) VPN Server is reachable within my home network

4.) VPN Server is reachable from outside my home network

I'd be more than happy if anyone could provide me with some hints on how to fix either of the following two errors

When I try to connect via L2TP (From in- or outside the network), I get the following error:

Aug 29 22:42:17 server racoon[164]: Connecting.

However, when I try to connect via PPTP (no matter if from in- or outside my network), I see the following error:

Aug 29 22:27:18 server pppd[16843]: The remote system is required to authenticate itself

Aug 29 22:27:18 server pppd[16843]: but I couldn't find any suitable secret (password) for it to use to do so.

Aug 29 22:27:18 server vpnd[16413]: --> Client with address = 192.168.1.226 has hungup

I have not yet tried the VPN server in Lion, but I would normally associate IKE traffic with L2TP style VPN connections and not PPTP connections. This might indicate the remote client is trying to make an L2TP connection and you have not yet setup that properly with the same shared secret password at both ends (this different the actual users login password).

Or of course you can correct the remote client and set it to use PPTP.

Talke a look at your router.. check to make sure it can pass GRE, and make sure your fiirewall isn't blocking it.
