Hi guys,
Kindly advice on what to do.
I have a cisco ftd managed via a virtual fmc, i have four interfaces on the ftd configured with Ip addresses.
I have anti-spoofing enabled on the four interfaces.
But i discovered that when the anti-spoofing is enabled on one of the interfaces which has a private IP configured on it as a link to my ISP router, legitimate traffics to a web server on port 443 are dropped when the anti-spoofing is enabled.
Kindly suggest on what to do.
