I have a Clearbox 300 running that has been running for a while. It doesn't do a whole lot. Today, I took it down to test out a new firewall but was having issues with that, so I hooked up the Clearbox again. It only has 4 1-to-1 NAT rules running on it to open ports 443 on two hosts and also port 80 on one of those hosts and basically has it pointing to 2 public IPs we have from our ISP. Whenever those rules are enabled, the host loses all internet connectivity and can't ping past the WAN port. When the rules are disabled, everything works again. I wiped and completely reinstalled ClearOS 7 and set up everything and it continues to do the same thing. I have a call in with our ISP to see if they have any ideas if it's related to the public IPs for some reason. Any ideas what would cause that?
