Simply run a CAT5 cable from any of the LAN ports on the Home Hub to WAN2 on the Draytek 2820.

From the Draytek 2820 go to WAN and enable WAN2 as an ethernet (I think) port. WAN2 will get an IP from the Home Hub in the same way as WAN1 gets an IP from ISP.

From the Draytek you can configure Load Balancing Rules which means that any computer on the Draytek network will be able to browse the internet on WAN1 (Zen) or WAN2 (BT) depending on the rules you set.

Dont forget that these two routers are seperate networks and if you have wireless enabled on the BT Home Hub then wireless traffic will ALWAYS go down the BT route. If you have wireless on the Draytek network either wireless access point or built into the Draytek router then Load Balancing will still apply.

Thanks
Sorted it by using static ip address from the BThome hub DCHP and its actual address as the gateway. Dynamic ip sent the 2820 in an endless reboot cycle.

Would love to have some help on configuring Load Balancing Rules and what they mean( point me to where I can read about them on the 2820).

Have a look at the user manual on the Draytek website - http://www.draytek.co.uk/support/userguides/Vigor2820%20User%20Guide%20V3.0.zip

Load Balancing is quite simple if you think about it logically.

On the 2820 you have 20 rules available to you. Each rule can apply to:
A protocol on a WAN port
and be filtered by the Internal IP of the workstation (or range of IP's), the destination IP (or range of IP's) and/or the destination port.

For Example,
Rule 1
Protocol: TCP
Port:WAN1 (with Failover)
Src IP Start: 192.168.0.1 (assuming a 192.168.0.x IP range)
Src IP End: 192.168.x.100
Dest IP Start:
Dest IP End:
Dest Port Start: 25
Dest Port End: 25

Rule 2
Protocol: TCP
Port:WAN2 (with Failover)
Src IP Start: 192.168.0.101 (assuming a 192.168.0.x IP range)
Src IP End: 192.168.0.254
Dest IP Start:
Dest IP End:
Dest Port Start: 25
Dest Port End: 25

With those two rules that would send any Port 25 traffic (SMTP) via WAN1 if the workstation IP was between 192.168.0.1 and 192.168.0.100 or WAN2 if the workstation IP was between 192.168.0.101 and 192.168.0.254. The "With Failover" means that if that WAN port is down (i.e. not connected for some reason) then by default if will use the other WAN port.

As a second example if you wanted all web traffic from ANY workstation to www.draytek.co.uk to go out on WAN1 but all other web traffic to use WAN2:

Rule 1
Protocol: TCP
Port:WAN1 (with Failover)
Src IP Start:
Src IP End:
Dest IP Start: 82.165.104.233 (which is the IP of www.draytek.co.uk)
Dest IP End: 82.165.104.233
Dest Port Start:
Dest Port End:

Rule 2
Protocol: TCP
Port:WAN2 (with Failover)
Src IP Start:
Src IP End:
Dest IP Start:
Dest IP End:
Dest Port Start:
Dest Port End:

I think (but you will need to check) that Rules are assessed from 1 through to 20 (in that order) so in that second example if you swap Rule 1 and 2 around so that Rule 2 was first then all web traffic would always go out via WAN2 as the condition (or Rule) has been satisfied.

Remember Load Balancing is based on Destination IP not name based so DNS has already happened when filtering. As a result rather than using WAN1 (or WAN2) ISP's DNS Servers think about putting in OpenDNS servers or a public non-ISP DNS Server (Google have Public DNS now).

Hope that helps....

Thanks

Set the 2800 ADSL to Ethernet pass through mode (bridge mode) and connect it to the WAN2 port of 2820. The 2800 will synch with DSL and behave just like the 120 ADSL modem and pass all control for broadband routing to 2820. You can still have its IP address in the same local subnet. Your default gateway would be the local IP address of 2820.
