DNSBL VIP Browsing Help Please.

[OsrRon]

System is out of the box install, including firewall rules. WAN is mainboard NIC. Lan and OPT1 are on an older Compaq NC3131 dual NIC.

Original issue was no DNSBL alerts and was not able to browse to 10.10.10.1, 10.10.10.1:80, 10.10.10.1:443, 10.10.10.1:8443.
All showed page :This site can’t be reached ERR_CONNECTION_TIMED_OUT"
I checked the Hardware Checksum Offloading box, and was able to browse to 10.10.10.1, 10.10.10.1:80, 10.10.10.1:8081.
This also allowed DNSBL to start working.

Attempted browsing to 10.10.10.1:443 or 10.10.10.1:8443 results in "10.10.10.1 didn’t send any data. ERR_EMPTY_RESPONSE" on both addresses. 
Browsing to https://10.10.10.1 gives certificate error but does show 1x1 pic.
I am getting BNSBL alerts.
Browser is Chrome Version 64.0.3282.186 (Official Build) (64-bit)

Any thoughts on what might be causing this?
