@IanCC I made an exact similar setup. it worked from my pc right away. so there must be something that blocking the internet for you. but what it may be is a mystery. Do you have any VPN policy...

@IanCC yes this is a weird error, everything looks right. which IP does the PC get when you connect it

@IanCC Ok disable this roule and try again. I have similar problem on one of my vlan with this enabled. but I enabled on all my VLAN, but try anyway for test

@IanCC Do you have any gateway ACL?

@IanCC everything looks right, try and ping 1.1.1.1 then you try to ping against eg google.com I did a test on my ER707, no problem.

@Frank18 This is not possible to use, you will find more information about supported devices in the release note....
