Cisco VPN :: VPN From 877 Router To Draytek 2600

I have a cisco 877 router connected to our adsl broadband at our head office. I have managed to set this up with Nat and DHCP all working to let multiple users access the internet through our single static ip supplied by the ISP lets say the ip is 1.2.3.4.Our internal network is 192.168.1.0 255.255. 255. 0.I have a draytek vigor 2600 at a branch office set up the same with a static ip addresss supplied by the ISP lets say the ip is 5.6.7.8.The internal network is 192.168.4.0 255.255.255.0
 
I am trying to set up a VPN between the head office and branch office so the branch office users can connect to our internal server(lets say ip is 192.168.1.2) to receive group policies,access files and also telnet into our database server(lets say ip is 192.168.1.3).I have attached a sort of running config that i have pieced together from bits i have read on this site and others. I have tried these settings and other permutations of these settings but i cant seem to establish a tunnel even though when i show int tunnel0 on the router it says tunnel is up and line protocol is up, if i show ip route it shows that there is an ip address for the tunnel and that is about it(No vpn light on).
 
If it makes sense and that I have entered the right information? I have highlighted the parts i am not sure about in red(Quite a bit and obviously not the exact settings but what i think it should be). Once all the settings are correct on the cisco will it automatically establish the vpn or do i have to dial it from the draytek.
