Hi there,

I am a little new to this so I have probably missed an obvious trick some where along the lines.

I have followed the instructions at both
http://www.draytek.co.uk/support/vpn_setup2.html
and
http://www.zimbio.com/Virtual+private+networks/articles/03uv5xjtsw5/Setting+up+PPTP+VPN+between+Draytek+2820+Router

I have all the remote access control methods enabled
PPP General setup is untouched
IPSec is untouched
Remote Dial-In User has my single user added

However when trying to establish this VPN connection from either inside my network or connected to my mobile 3G modem I get an error from Mac OS saying the 'PPTP-VPN server did not respond'

As well as trying to connect to my IP address I have tried establishing a VPN connection from inside my network with the internal address of my router and I get the same results. I have spoken to my ISP and they say there is nothing they are doing to block the VPN.

Is there a firewall rule I need to apply to open ports related to VPN?

MacBookPro - Snow Leopard 10.6.3
Draytek Vigor 2820n 3.3.3_232201

I'm a bit confused why you are trying to connect to your VPN internally. That just won't work.

I have the same set-up. MacBook pro to Vigor 2820. I have set-up a simple PPP connection and it works ok, connecting on my iPhone or via my 3G dongle on my MacBook - but obviously only externally.

Do you have a static IP address or are you using DDNS?

The internal attempt was me clutching at straws.

I have a static IP Address pinging doesn't responde due to my firewall. However with the use of Zenmap http://nmap.org/zenmap/ I can see that it is my router and what ports are open.

Surly it's not that difficult is it?

First thing I would do is temporarily un-tick "Disable PING from the Internet" on the router management page and double check you can ping it directly.

Put it back on afterwards.

Ok I so with PING from the Internet enabled I can successfully ping my router from my mobile connection. I can also log into the router from the mobile connection. So I can confirm that my IP address is good.

Are there any ports that I need to open to enable VPN?

Am I right to be attempting to my external IP address without any port number?

Thanks for your help.

So I've got it all working what I've done is,

Added opened TCP/UDP on Port 1723
Added Protocol: 47
To the Data Filters (Firewall rules)

And importantly then re-booted the router and all is now working well

Could the opening of port pleased be added to the how to VPN work?
