'Morning all on the QBIK board.
After a long time our servers' are in upgrade to Wingate 8x on HP hardware and Windows Server 2012 Essentials.
The first one to go into production has become unstable and I have a question which might reduce my build time if you could suggest an answer!
After a random period of client usage (varying from minutes to several hours at most); The external link to the router becomes disabled or at very best unresponsive; This forces a reset.
Today I have thought to override the MTU to 1450 and am trialling that.
The correct HP / Broadcom drivers are applied and the Internal NIC does not have a gateway or DNS entry, also I turned off the MS Firewall (although not sure this is still required - please comment?).
Here is a snippet from the Global Log:

(Router is the .200 IP // static server external NIC is .100 IP // I have always used this private range on my external NICS and hope it isn't the culprit and I am using Wingate DNS for simplicity at this stage.).
