Connecting two LAN's across the Internet

Ok,  I have two offices geographically separate both with fibre broadband connections.

Office 1 has an internal network of, Router internal IP is
Office 2 has an internal network of, Router internal IP is
Both routers are Draytek 2830's

I want to setup a link between the two offices so that staff can access files between the two.

What is the best way to achieve this and how do I actually do it.  I'd rather not break my routers as I tinker about trying to get it right.

Thanks in advance.

What you are describing there is  a VPN. (Virtual private network)

I am not familiar with this particular device, however the spec online say it supports LAN-LAN VPN, so it should be possible.
The folowing article gives you a step by step guide on how to configure a lan 2 lan connection.

It would be a best practice to try this on another device, so that you know the steps before you do it on a production enviroment.

Before you do these test also make sure you have a backup of the configuration, so that you can go back fast and easy:  

to backup:
1Logon to Router Web Configurator page, choose System Maintenance >> Configuration Backup.
2. Click the Backup button.

to restore:
1. Logon to Router Web Configurator page, choose System Maintenance >> Configuration Backup.
2. Click Browse button, choose the config file that you'd like to restore then click the Restore button.
