Hi,

I'm looking for a little help here. I have a 50M business broadband connection from VirginMedia with 5 static IP addresses. I'm using the supplied SuperHub (with the business firmware, which is different to the consumer firmware, apparently - mine says V5.5.2R04-BU).

If I assign static IPs to a couple of Macs and plug them into the SuperHub via ethernet, they can access the internet perfectly.

If I assign a static IP to my Airport Extreme (behind which sits the rest of the network), I can't get from the AE to the internet. The SuperHub is in bridge mode because I have static IPs and my Airport Extreme provides DHCP to my internal network.

Weirdly, the following works:

- Ping from one static IP Mac to the other
- Ping from the static IP Macs to the Airport's static IP
- Ping from anywhere on the Airport's internal network to either static IP Mac

Simply put, nothing can route out of the Airport's internal network to the internet.

I would appreciate any suggestions that anyone might have.

Thanks,
Fraser
