Draytek Router help

[skookum]

Hi,

Just wondering if anyone has any ideas to whether the following can be done.

We have two routers a Draytek 2930 connected to a Cisco 800 running a 30 mb leased line. As a back up we also have a 90mb FTTC running on a Draytek 2830.

The Draytek 2930 runs all our operations stuff, cloud software and VOIP phone system both wired and wireless. The Draytek 2830 runs redundant only supplying wireless connection for staff to use.

In the event of a leased line outage I manually unplug the 2930 from the switch and plug in the 2830. Ideally I would like to join the two routers together.

To be honest I find the 2930 dashboard a bit bewildering. Obviously they would have to have different IP addresses and DHCP turned off on one or the range changed.

I also do not want to use load balance, I only want to use the FTTC if the leased line is down.

Can it be done?

Surely you have an FTTC modem connected to the 2830, so plug that into WAN2 on the 2930. Then throw the 2830 into a corner.

I like your thinking. However it is a 24/7 365 day a year company. The call centre must be operational throughout this time. Hence why I have kept two routers to cover the possibility of one failing. I also keep a spare POE switch in stock. Any downtime we have to cover with remote workers. Being a small company of less than 20 employees my budget is extremely small, well more like a pub whip round so I am having to use equipment available to me.

Previously I had a problem with Failover. The setup before our VoiP was installed was 90mb FTTC and a back up ADSL 30mb on the Draytek 2830. Our servers are located at Amazon and some DNS or routing problem occurred. The internet was connected but it couldn't connect to anything Amazon rendering the failover useless as the connection was not cut.

I suspect this is a highly rare thing to happen but I have been asked to find a solution just in case it ever happens again.
