I have several virtual machines whose network gateway is a Microsoft forefront server. I cannot connect to s3 storage from any of those machines.
The vm's are running server2012r2 or server2007r2, all with windows firewall completely turned off.
If I change a gateway to a Sonicwall firewall the problem goes away. I have a reason for NOT WANTING to use the Sonicwall for these machines, so that is NOT a solution to this question.
The forefront server has an outgoing rule all internal to all external all protocols all open. No malware rules are active on this connection.
Why can't I connect to s3 through the forefront firewall? Thanks.
