New toy arrived at the office two days ago, shiny Vigor 3900. I have managed to get it to replicate the basic setup I had at head office for the 2820 it is replacing, but I am struggling to get to grips with two of the new advanced features I wanted to use.

1. SSL VPN: I have set up a user in User Management - User Profile as so:



I have then enabled the SSL Tunnel Service in Remote Access Control and the HTTPS access to the router. At a remote location I can login to the router and use my password, however there is not an option for running an SSL Tunnel, only for SSL Web Proxy and SSL Application. The menus are completely different to those shown in the Draytek guide here below, so I don't know whether I am missing anything:

2. VPN Tunneling: I am very keen to try to set up a 3 line load balanced VPN tunnel at head office for the 10 remote branches to connect too. I have found this guide:

http://www.draytek.com/index.php?option=com_k2&view=item&id=2021:faq-article-2021&Itemid=293&lang=en

However that assumes both ends can handle GRE. In our setup the branches all only have Draytek 2820's with a single WAN (though we are in the process of upgrading them to dual WAN).

If I was to set up the Server end as per that guide and just set up the 2-3 seperate VPN's as standard on the 2820 would that achieve what I need or would it cause issues?
