[j-nsp] Firewall Filters and BFD

[Thomas Eichhorn]

Hi all,

I currently try to protect my lo0 interface by dropping
all unknown traffic - which usually works very well - but
now I have BFD enabled - but nor as protocol or port it is
defined in the well-known options neither I can make out
a specific port it uses - I've seen 97,98 and 3784, but even
allowing all these ports didn't make BFD work.

Has somebody here an idea what to allow or maybe even
a working configuration for this?

Thanks,
Tom
