Hi,

I have a very poor Virgin Media connection. The bandwidth is fantastic, but the latency is erratic and has peaked at 1000ms.

I've placed an order with gamingbroadband.com* to have my BT line reconnected and I would like to use that as a dedicated gaming connection. It's a 30 day rolling contract, so I thought I'd give it a go and see how they work out. If I manage to break my Virgin contract due to the poor connection, not being fit for purpose, I may use the new connection as my main broadband.

I have an old BT Openreach FTTC modem and I'd like to achieve the following:
  • Connect Asus router to both the Virgin 'modem' and BT Openreach modem.
  • Route all of my gaming PC's traffic via the BT Openreach modem.
  • All other traffic via the Virgin modem.
  • I have a single patch cable from the Asus router to my home office.
    • This connects to a Netgear managed switch.
      • Gaming PC
      • Aruba work VPN device
      • Home server
Is this possible?
  • Could it be achieved using static routes or would I need to use the Dual WAN function?
  • Does the Dual WAN function work?
  • How would I configure the 'Load Balancing' for this requirement?

I haven't been reconnected to Openreach yet, so I can't see how the BT Openreach modem presents the connection on it's LAN port.
  • If it presents a local IP (e.g. 192.168.0.1), then I presume Dual WAN won't be necessary and a static route could be used?
  • If it presents a WAN IP (e.g. 80.3.2.3), then I guess Dual WAN is the only option?
Thanks,


* I called the helpline for gamingbroadband.com and was immediately answered by a friendly and helpful UK worker. I had a few specific questions regarding the service and was then transferred to the business owner. He explained that they were a subdivision of a specialist VOIP fibre company and their network is designed for low latency connections. He seemed to believe in his product and took the time to answer all my questions. I can't see customer support being a problem.

You would have to use Dual WAN irrespective of what the IP addresses are because that's what you will have (two WANs).

Sorry, I've no experience of using that option. I know there are lots of posts in these forums from frustrated users that couldn't get it to work properly. Whether those posts are representative of all users I don't know.
