[PATCH 03/20] netfilter: nat: merge nf_nat_redirect into nf_nat

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

 



From: Florian Westphal <fw@xxxxxxxxx>

Similar to previous patch, this time, merge redirect+nat.
The redirect module is just 2k in size, get rid of it and make
redirect part available from the nat core.
