Hihi,

So vanilla install of WS2008R2S, disabled FW with GP and trying grab SNMP with another host on the same subnet. The output of both if/ipconfig's and nmap -p 161 is below. Both machines running in VirtualBox with the connections bridged to the wireless adapter which is the only active connection on the host machine.

Might be a dumb question, but did you enable any SNMP services? –  Chris S Feb 9 '12 at 14:08
    
Update, went back through the GP and re-checked all settings, firewall is definitely disabled and I'm not getting port closed instead of filtered. What's going on? :< –  Jake Feb 9 '12 at 14:09
    
And yes, SNMP is enabled / configured. Will try it from another machine. –  Jake Feb 9 '12 at 14:09
    
Where is GPO are you disabling the firewall? Computer Config -> Policies -> Windows Settings -> Security Settings -> Windows Firewall -> Windows Firewall -> Properties -> Firewall State? –  Chris S Feb 9 '12 at 14:19
    
Yes and it's showing as disabled and controlled by GP in the Windows Advanced Firewall GUI. Added partial netstat output to main post, hopefully will help. –  Jake Feb 9 '12 at 14:24

Did you explicitly allow SNMP service to allow packets from remote host IP address (Services, SNMP, properties, Security). It will only allow localhost by default.

This post here will walk you through configuring the SNMP Service to your liking.

Something very odd to do with the VirtualBox instance. No matter, thanks anyway!
