I've just purchase a Windows Server 2008 R2 VPS plan and I was alarmed to see the default configuration had Windows firewall disabled. I've enabled the firewall and disabled most of the inbound rules, but I have some uncertainty about the rules in the Core Networking category. I know that I don't want DHCP in, so I've disabled both the IP4 and IP6 versions, but I'm at a loss for the other entries in this category:
IGMP IPHTTPS IPv6 Multicast Listener Done, Query, Report and Report v2 Neighbor Discovery Advertisement and Solicitation Packet Too Big Parameter Problem Router Advertisement Router Solicitation Teredo Time Exceeded
The only planned inbound connections for this server are HTTP, HTTPS, and RDP, so my preference is to disable all of these rules. However, I want to make sure this isn't going to cause any unexpected problems.
