Trooli Bridge Mode

Does any one have direct experience of Trooli? how do you find them?

Their service is available on our industrial estate in Uckfield, business Boost 300 service should suit us perfectly and £50 per month is great value.

But they have quoted an extra £25 per month to be able to use our own firewall:

"If you have a Trooli business service and you have also taken our Bridging Service option, you may use third party routing equipment behind a Trooli-supplied Draytek bridge (modem). Non-Trooli equipment connected to the network is not supported by Trooli and we can’t assist with any technical issues that you experience with third party equipment."

Which has left me shocked. Does anyone have any experience of this? what Draytek device do they supply? is double nat possible from their standard router? ? ?

Thanks
John

PS just found this thread which looks very useful

I have a Gigaclear consumer service. The box was put into bridge mode a couple of years ago. I don't pay any more for the service, and I don't expect them to support the router that I have connected to their box, other than to tell me how the connection should work (DHCP not PPPoE etc).

Maybe you could persuade Trooli to make a similar offer!

Personally I would avoid double NAT as port forwarding gets awkward.
