I had set up a series of DNAT rules to act as last default rule for each inbound IP to take any traffic and forward it to a none existant IP address. The net effect was to not respond to unwanted traffic.
The DNAT is basically Any Source, Any Service to External IP ***.***.***.*** is dnatt'd to Blackhole, Any Service. ( ***.***.***.*** is one of my external IP addresses of course)
In 7.202 and prior, I could save this rule. In 7.3 the rule will not enable and complains on the "Any Service" from the source. It flashes red and will not save and it will not activate.
All of my blackhole rules are disabled.
On the grc.com sheilds up website, I now show as all ports closed vs. all ports stealth mode. Of course, this identifies the fact that we exist to allow hackers to see us and then try to attack us. I prefer to be stealth.
Any ideas? - is this a bug?
