This is driving me bonkers!

Theres a draytek router in work and I have one at home. I've set up a PPTP profile and I know it works because I asked a local IT dude to check it is working. Unfortunately, I can't get hold of him at the moment.

He managed to get it working no problem. Me on the other hand, just keep getting error 800: Unable to connect.

I'm 95% sure the router at work as a working profile. I just can't access it from home.

All help appreciated.
 
Are you trying to get the 2 routers VPN'd together?? If so, have you checked to see if you can do a regular VPN session from your machine into work?
 
Try re-creating your VPN profile on the work router, to make sure the password etc is correct. If you want Gateway to Gateway, you need to make sure the configuration is mirrored on both routers (the encryption etc) and only thing that is different, is the IP of the peer.

I did find this on the Draytek website, but I dont know how old it is, so it may still work.

I set the profile up on the router and then from home just used Windows7 VPN connection wizard to connect. Just get unable to connect message.

Does it matter that I've got static IPs at work and at my home? Will that make a difference?

I do all that in the link and get the same result.

I'm trying to set up VPNs for all our work locations so I can have NAS boxes at each location and have them replicated with our file server in the office. I've been told I can do this via VPN.

Some ISPs block PPTP traffic, have you checked for that?

I didn't know that. Although because the IT guy I asked for advice was able to log in from his home makes me think it probably isn't that.

I'm on the same ISP as my work (eclipse)

One quick question - when Windows asks me for the address - I do put in the static IP address yes?

You put in the WAN address of the router, so yes, if thats what you mean.
 
Ah, well that is what I'm doing.

Would it make a difference that my home router also has a static IP?

Its so frustrating because most people I know with Draytek routers find all this VPN malark easy.
 
I think I know what I'm doing wrong.

Don't both LANs have to have different internal addresses? Like one place having 1.1 at the end and another having 2.1 at the end?

Both routers being draytek they both end 1.1

You could give it a go and it would make things more simple as you wouldnt have to worry about duplicate IP addresses.

Probably. With the IPSec site-to-site VPNs I have running you definately need to have different address ranges at each site.
 
You would need to have a different internal ip address subnet. So if you work uses 192.168.1.0/24 you will need to be on a different subnet.

The issue is your router is seeing traffic destined for the same subnet and not passing it down the tunnel.

We had the same sort of issue with some staff so we changed the subnet and it worked fine.
 
It was the IP addresses.

Both routers are Draytek so they default to 192.168.1.1

Changed one to 2.1 and it worked first time.
