My company server suddenly blocked inbound traffic over night. I can access
the internet on the server with no problem, so outbound is good.
I've ran the "Net Diagnostic" utility both network cards passed.
I pinged the NIC cards (127.0.0.1) both passed that.
I checked the TCP/IP filters on each card and they are set to permit all
TCP/UDP/IP Protocols. (Enable TCP/IP is not selected)
Iâ€™ve uninstalled, reinstalled both adapters and configured static settings.
Inside my router settings, under attached devices I see the assigned server
static IP address (I've unplugged to clear the address and inserted the cable
Using the router diagnostics I tried to ping the address. I received the
"Request timed out".
There's isn't any firewall software or hardware other than the router itself.
