Bought a Draytek Vigor 2820 to take advantage of its ability to accept two ADSL connections and Load-Balance between the two. Additionally, if one ADSL line went down, the 2820 provide seemless failover to the other ADSL service without me having to run around and change network settings or adjust any DHCP servers.  

But I couldn’t get the 2820 to work with the second ADSL connection – where you plug your second router into the front of the 2820!  

Turns out that if you disabled DHCP on that second router then it does not work at all well. I disabled mine because I have other DHCP servers that dole stuff out.  

The ‘fix’ then is to enable DHCP on that second router – set it to give out just one IP address. Then the 2820 will gratefully accept the IP address it’s given and then WAN2 starts to work!

The 2820 works very well, by the way. I was playing a video off the BBC news website and then I pulled my ‘active’ ADSL cable from the socket. There was then just a brief hiccup and then the video continued to play!
