Sophos fire wall Dual stack Control Center/system interfaces WAN link manager is red why not green?

Hi All,

I recently added IPv6 support to XG FW and something says not right. I have pubic v6  address on WAN link, 2 private ranges on LAN and DMZ . I am using router advertisement for IPv6. The FW rules show traffic on v6 both directions, The v6 test web sites give it 10/10 pass (https://test-ipv6.com/). 1/2 my traffic volume in reports is v6. It all works great.!

However the gateway and interfaces turned red after I set this up and persist today, is it really broken? seems fine to me. Thoughts anyone?

  • Please show us the gateway, which is selected there and a proof, you can ping it from the SFOS firewall. Because this is most likely the case, the firewall cannot reach the gateway via ICMP.
