Contrary to what Sky will tell you about how to setup a router to use their service, it won’t work. At least not as they explain it.

I tried a few different ways but in the end, these worked for me:
Encapsulation: RFC1483 Bridged (Your router may call this: IPoE)
Don’t auto-detect your IP address. Instead enter the static IP they gave you as a /24 with the first IP in the block as the gateway.
If it is all working, you should see it on your status page. I could pretty much get the DSL line to come up on most settings but getting it to log a gateway was an impossible task. All good now though:
