VPN trouble

[Wilko70]

I have set up a Draytek 2200x router at my office to enable initially myself and later others to work from home.
I have at home DSLline connected to Arescom NetDESL 1000 (came with the subscription) which is hooked up to a linksys WRT 54G wireless router. Seems complex but added the wireless bit so I could sit anywhere in the house and work.
Current situation:
- can ping the public ip address of the dratek, can also manage it remotely via browser
- CANNOT connect via DSL get an error 800 ?
- via regular anolog connection I could connect with my laptop.

I think the problem lies somewhere in the Arescom and Linksys set up. Can anybody suggest a possible solution?

Error 800: Unable to establish the VPN connection. The VPN server may be un-reachable, or security parameters may not be configured properly for this connection.

Resolutions:
1) if you have firewall, open TCP Port 1723, IP Protocol 47 (GRE).
2) make sure you can reach the VPN server by using ping. Sometimes, poor connection can cause this issue too.
3) You may need to updated firmware on a router or firewall if other OS (win9x/nt/me/w2k) works except XP.
4) The VPN server may not be able to get IP from DHCP for the VPN client. So, you may want to re-configure VPN host networking settings. For XP pro VPN host, go to the Properties of the VPN>Network, check Specify TCP/IP address and Allow calling computer to specify its own IP address, and uncheck Assign TCP/IP addresses automatically using DHCP.
