WAF domains will not be covered?

Perhaps I am missing something simple here, but after setting up WAF for an internal HTTPS server, I am getting the following message when I try to save the rule:

Following domain(s) will not be covered by selected HTTPS certificate

"remote.domainname.com".
1. remote.domainname.com

actual domain removed for privacy of course...

Anyways, I am not sure why the firewall will not use the cert to cover this domain. I generated a CSR with the firewall, got the cert from my provider, uploaded it, and it took it. The provider did provide to me a .crt that I opened and exported as a .cer using windows cert wizard, but that shouldn't matter, right? Also, I know that the WAF needs to have the .key file, but since I generated the CSR with the firewall, it has that already and didn't ask for it when I uploaded the cert. 

Also, I checked to make sure that my old DNAT rules do not have 443 included since I understand that I cannot have more than one firewall rule referencing that port. There are other DNAT rules still in place for non-web ports that this application accepts traffic on. 

Finally, I have set up the user portal to use a port other than 443, so I don't think there is a conflict there. 

The firewall is an XG210 running SFOS 18.0.4 MR-4

  • I think I found the root of the issue. I still have migrated NAT rules in place, plus some rules made by the server access assistant that are forwarding external traffic to my internal server. I have found that if I disable those rules, the WAF rule seems to still forward traffic to the internal server, but something still isn't right. 

    Is it necessary to have a NAT rule to forward traffic in conjunction with the WAF rule, or should I only have a WAF rule?
