I have a DSL modem/router and apparently need to create rules for UDP and All Other Packets IGMP. How do I, assuming I need to, create rules for these? The picture below shows my log:
Hi JVM The packets shows in the picture are: In UDP: SSDP service packets use by some application like Wengo (a VoIP program) In IGMP: Igmp packets for "IGMPv3 routers" (used by some application like Azureus and Vlc...) You may create rules to authorised these packets or, if there is no problem with your modem-router or appplications, simply ignore them... A rule for SSDP looks like this In UDP from @IP local ports 1025 to 5000 remote port 1900 Applications ... : Generic Host Process for Windows (svchost...) A rule for the Igmp packet looks like this: In IGMP Source : from @IP Destination: IP equal to 224.0.0.22 Igmp type: all Hope this help.
Hi JVM, Your logs are looking exactely like my ones! 1.) You will need one rule allowing UDP traffic through port 1900 (like the one "Climenole" describes in detail) 2.) No rule is needed for the IGMP log entry. At least for me it works without a specific rule Thomas
I had to set Source Ports for UDP to All because the range exceeds 5000 -- goes as high as 64396 . Is that a problem? Actually, my programs were working all right but I thought I should set a rule for it.
Hi JVM Higher than 5000 ? Strange but possible: there is some application using local port > 5000 in UDP For example: Skype: in UDP it use port 21047 Gizmo Project; in UDP it use port 64064 In W xp the default port range is > 1023 to 5000 and it's in this parameter: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters MaxUserPort default value 5000 (This can be changed to an higher number...) I guess this parameter is for TCP ports only... So change the rule for the UDP ports range in use. There's no choice I guess.
Hi JVM LOL These ICMP type 3 code 3 = port unreacheable ... Make a copy of your rule set, rename it by adding .TXT at the end and upload it here ...
I deleted the rule set for UDP and and now no more ICMP's, but now I'm back to all those UDP's Since I don't have any problems, I'll leave it alone unless someone knows how to fix this issue.
