Draytek 2820 VPN Configuration

Posted on 2010-08-24
Last Modified: 2012-05-10
Hi, I've got a couple of 2820s spread across the internet.

I have one main site which has LAN to LAN pptp VPN configured (Dial in and Out) for all the sites. Let's call the main site Site HQ.

So it's configured from

Site HQ <--> Site A
Site HQ <--> Site B
Site HQ <--> Site C

How do I configure the routers so that traffic goes from Site C to Site A through Site HQ? And vice versa?

I was playing with the routes but it didn't work out so well.

You were on the right track - the easiest way in a network this size is with static routes. Assuming that clients at HQ can ping clients at any of the remote locations, and that the clients at the remote sites can already ping resources at HQ, you just need to set some static routes either on the Drayteks at the remote sites.

If the sites have the following example subnets:

HQ Draytek:
HQ: 192.168.0.x
SiteA: 192.168.1.x
SiteB: 192.168.2.x
SiteC: 192.168.3.x

On the Draytek at SiteA you will need the following static routes:
To route to SiteB
Destination IP Address:
Subnet Mask:
Gateway IP Address:

To route to SiteC
Destination IP Address:
Subnet Mask:
Gateway IP Address:

In order for ping to work, you also need the corresponding static routes configured at the other end (otherwise the packet will  get there, but the router at SiteB/SiteC will not know where to send the reply back to and it will look broken, even though the packet arrived at it's destination).

You'll need to change my examples to the correct Destination IP Addresses and Subnets for your network, but provided that the HQ->SiteX and SiteX->HQ routing is working correctly, all you need to do is to tell all traffic for other remote networks to go via the LAN IP of the HQ router.

Hope this helps,
