Hi,
when publishing a port forwarding (non-web server) rule for an unknown (by TMG) protocol - TCP/1521 - our windows 2008 R2 box halts ("hardware malfunction" BSOD with no error messages "the system has halted"). We've updated firmware on the box, updated all the drivers, all the firmware, swapped out the memory, reseated HDDs & RAID card. Windows is updated to the max, and rollup 2 applied to SP2 of TMG 2010, version 540.
The "halting" only occurs when the network interface receives a packet for this rule. The box is otherwise completely stable, which is why I'm leaning towards aTMG + Driver rather than hardware error. The tin is a Cisco C200 with LSI megaraid, Intel networking. 2008 R2 installed directly to tin, no vmware.
Anyone experiencing similar problems, I'd be grateful for any advice :)
Thanks in advance,
Sam.
