[LARTC] TC basic match problems

[Peter Rabbitson]

Hello,

I am attempting to match on a single bit of the NF mark value, and after 
hours of reading and googling I can not get the syntax right. It got to 
be something very simple, yet I can't find it. Any help will be greatly 
appreciated.

Thanks!
