VPN PPTP Connects but doesn't work

I used to use the built in PPTP VPN connection in the regular Leopard to connect to my employer just fine. It allowed access to the exchange server, intranet web pages, and file servers. Now with the same connection settings I can connect and authenticate just fine but it's as if none of the network requests are going through the VPN. None of the addresses resolve, for file servers, web servers or exchange. I even tried IP addresses and they weren't found either. Watching the VPN traffic meters in the control panel revealed no activity even though various network request were being made.

I tried manually adding DNS info into the VPN settings to no avail. I deleted all DNS info and let it populate itself and no luck. I have an old G5 sitting here with regular Leopard and the VPN connection works just fine.

I've tried deleting the VPN and re-adding and that didn't work either.

This is making me really nervous... I NEED my VPN. Please help 😟

Hi folks,

I have the same trouble. But I could overcome for a single time using:

Deleting of the /Library/Preferences/SystemConfiguration folder.
Restart
Konfigure VPN PPTP including "use VPN for whole Internet access"
Pushing VPN (PPTP) configuration to the top of the list.
Activation of internet sharing for a short time.

Sorry, but I can not tell, what was the real helping act.

Afterwards following tries did not succeed as before.

As far as "Konsole" tells, the CHAP results in success, but following CCP exchange fails by "rcvd [LCP TermReq id=0x1].

I had the same issue with out company Exchange VPN server.

I could connect VPN, but no traffic went through.

The issue got fixed when I turned on Internet sharing and then then turned it off. After that the traffic started to route the right way.

I had the same issue. Disabling internet connection sharing fixed it!
