Sysgate Personal Firewall 5.5
Hello!
This is Trafic log in Sysgate Personal Firewall 5.5. What is this? This 192.168.0.100 is my IP (I'm using Broadband Router). Why is SPF blocked this protocol? 03/02/2004 21:23:22***Blocked***15***Incoming***UDP***192.168.0.100***00-50-04-A2-41-D2***1028***239.255.255.250***01-00-5E-7F-FF-FA***1900******Izi***KRNEKI***Normal***3***03/02/2004 21:22:17***03/02/2004 21:22:17***Block_all*** Izi |

Re:Sysgate Personal Firewall 5.5
Hi Izi
That would appear to be just incoming multicast traffic, specifically ssdp (1900). This could be a result of of systems behind the router having that service enabled (Universal Plug and Play), the router being UPNP capable and enabled or both. Nothing to worry about. If you do not use or need UPNP or use multicast services, you can disable it on all systems. Edit: The source address from your log is what indicates this. "Addresses in the range 224.0.0.0 to 239.255.255.255 are set aside for the special purpose of providing multicast services in the Internet. (Multicast services allow a computer to send a single message to many destinations.) Various addresses in this range are used by routers and others are used by hosts that are listening to multicast sessions." - iana Regards, CrazyM
