OSPF Firewall Packets dropped

David Garcia Jr.
I am using Zebra to get OSPF updates. How do I set up a rule to allow OSPF to pass through and to the firewall? Thanks in advance for all the help. I will like to make a howto for those of us can't RTFM. So this will help a lot.

    David,

    I do not have a OSPF router to check my suggestion
    but you could give it a shot.

    Define the multicast network as 224.0.0.0/8.
    In NETWORK/ROUTING you can configure a interface
    route.
    example: multicast-network -> internal interface

    Let me know, if that works!

    regards

    Thanks so much for the help. I tried that, but then finally figured out that Astaro does not have multicast routing complied in the kernel. I really need the kernel to have that compiled in. I would like to see if I can recompile the kernel or maybe the Astaro team can put out a kernel that supports IP multicast routing. Running a netstat -g gives

    netstat: no support 'AF INET (igmp)'

    I am thinking that if igmp is loaded in the kernel as one of the IP protocols with IP multicast routing support enabled, Zebra and OSPFD should work like a charm.

    Thanks, 

    David
