Re: Can anything be done about jitter and packet loss
 

the windows route command.

My physical setup was something like this.

VM modem connected to dir615, dir615 connected to a gigabit switch (is a router but on my lan functions as a switch), adsl router connected to that same gigabit switch. cable from that gigabit switch to pc.

Configuration wise, its probably important to have both adsl and cable routers on the same subnet.

Then windows you configure one of them as your default gateway, pick one or the other. You can then add another gateway in the advanced tcp/ip config and set it a metric, the default metric is 10, a lower number is higher priority and a higher number is lower priority, so if you add a 2nd with metric 20 then the default gateway will be used unless it goes down.

Now you can do things like toggle the metric of the 2nd gateway to change the effective default gateway however what makes it much better is the route command. You can eg. set a route to 8.8.8.8 on the 2nd gateway with a metric value of 5 and that would route all google dns requests over that gateway whilst all other stuff still goes to the other gateway.

Thanks Chrys. I'll think that through.

Far as changing it on Windows is concerned you could script it so it's as easy as clicking a shortcut.

On the other hand, that obviously only takes effect on the local machine - in my case the router itself has a script to do a similar thing but as it's on the router it applies to all machines on the network (which may or may not be what you want).

Better route would of been to use a dual wan VPN firewall device

Then your network load balances between the 2 connections and if 1 falls over it switches to 2nd for 0 downtime

In theory when infinity get 80meg out the door and vm upgrade to 120mbit you should be able to get a load balanced download speed of 200mbit

Far more efficient way of using both connections simultaneously than switching between the 2 manually.

Seeming as you are paying for both may as well use both at the same time

thats ok if you happy with automation, it depends if you want automated balancing or control.

Re: Can anything be done about jitter and packet loss
 

Other than the Draytek 3900, doe you know which other routers do dual WAN trunking?

And thanks everyone for the advice I'm getting.

Re: Can anything be done about jitter and packet loss
 

The Mikrotik RouterBoards can be configured to handle dual WANs. This configuration example may suit your purposes, it routes traffic based on the LAN IP address allowing you to specify which gateway traffic from any given LAN client will be sent to:

Load Balancing over Multiple Gateways

You can also use a similar approach to route traffic according to type:

Per-Traffic Load Balancing

You can also round-robin with user sessions:

NTH load balancing with masquerade

Looks like these could all be augmented to failover automatically in case of an outage with scripting:

Improved Netwatch

An alternative would be pfSense on a PC Engines ALIX which should be good for +90Mb/s throughput.

Openwrt?
