How to filter connections using connmark with libnetfilter_conntrack

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I want to get conntrack update events for all connections that go
through FORWARD, but not through INPUT or OUTPUT.  I tried to set a
connmark bit and check for the mark.  But I saw no way to filter for a
given mark value using a kernel filter.  Did I miss something?  I
already filter in userspace, but I want to avoid this if possible.

Regards,
