I am looking for a reliable, good quality ADSL device that can be used as a transparent bridge to a Linux machine.
Can anyone make any recommendations on devices that do this? Reliability is far more important than price (these will be for business customers) and I would prefer something that has firmware upgrades available without a support contract.
I use a D-Link 302G at home, the one that Telecom supplies with their Home Customers Jetstream Starter Pack thing. If you have the Modem to the NAT then it's bloody awful, but if you upgrade the firmware to the one posted on the dlink.com.au site, and then just disable NAT on the modem web-interface (annoyingly you _have_ to use Internet Explorer to do this, Firefox wont do it at all) it turns into a transparent proxy, and will give the external IP to the Linux box through DHCP. I.e. with NAT disabled it behaves almost exactly like a Cable modem. And yes the firmware is freely available off of the dlink.com.au website, but you have to change some setting from its default so it will I haven't had any troubles with this so far, and it's been working a lot better than with the modem doing the NAT, but I've also only been running it like this for about 2 weeks or so... More details on this process are on the WLUG site : http://www.wlug.org.nz/DSL-302G Scroll down to near the bottom, where it talks about "half-bridge mode".
