Internet issue with VLAN

Hi Everyone,

We're experiencing a very strange problem with our PowerConnect 6248. We have a VLAN (8) that we use as an internet VLAN. Our internet connection is connected to VLAN 8. It consists of a bunch of ports. I have a Cisco ASA connected here too that works perfectly.

We also had a Netgear router connected here that basically just provided a guest Wi-Fi network. One of our public IP's were configured on the WAN port of the Netgear. This worked perfectly for many years. It's suddenly stopped working a month ago, I just bought a new router and configured it and connected. It doesn't work, it can't get to the internet at all.

I can however connect my laptop to the same VLAN using the same public IP on my Ethernet card and can then browse the internet without issues.

We have tried 4 Wi-Fi routers so far and all have the same issue. We're not sure where the problem is. Please see the config below.

Any help would be appreciated.
