The main goal is to isolate/block traffic from user that is performing "possible syn attack" before it blocks access to everyone else. Why does it stops accepting new connections globaly for all users, not just from the IP address source with "possible syn attack" activity and what would be the correct flood mitigation setup to stop accepting new connections from the IP address before it "locks" th FTMG completely. When TMG says "will protect the network accordingly" -how does FTMG protect the network?

The next step is to configure a SIP trunk with a Lync 2013 mediation server. Since TMG 2010 is basically end-of-life this reverse proxy can be configured using an F5 load balancer, I’ll get back on this in a future blog. On my box this threshold is currently set at 400 so the global number of half-opened connections is 200.Ĭan someone explain what is happend at that point? The TMG server in this blog will publish additional web services that are used in a Lync environment via the Internet. I have learned that a "POSSIBLE SYN ATTACK" is mitigated by FTMG mitigation mechanism.įTMG has a threshold defined for maximum of half-opened connections = Half the maximum TCP connections per IP address. There is no offending IP address in logs. FTMG does not accept RDP connections, won't replay to ping, won't route traffic. Short time after that all traffic is gone. Posted by George Khalil on in Forefront, TMG Today I will continue my series of articles on Microsoft’s latest Forefront Threat Management Gateway (TMG) and will focus our efforts in publishing Windows 2008 R2 Remote Desktop Web Access (RD Web) and Remote Desktop Gateway (RD Gateway) to the world wide web via TMG. Forefront TMG 2010 prevent abuse of networks from internal and external entity. There are LOG entrys that show: Forefront TMG has detected a possible SYN attack and will protect the network accordingly. Forefront TMG provide additional protection capabilities to help secure the corporate network from external/Internet-based threats. Soon after that TMG stops accepting new connections and stops routing traffic (outbound and inbound traffic are both affected) from ALL IP addresses (not just the offendig one).

This is going to reduce the great deal of problems but am i trying to find out what is happening behind the scene and why. Install Forefront TMG 2010 using documentation from your vendor. I have a problem on our network with FTMG and trying to understand the problem and FTMG mittigation mechanism.Īt our network any user can make Forefront TMG unusable by using uTorrent aplication! FTMG stops accepting new connections and stops routing traffic (both outbound and inbound).įirst of all i know that i can block access to torrent sites and disable users in a way that they are unable to install uTorrent (and other tools) and disable the use of torrent tracker sites, and disable the downloads of torrent files.
