[PATCH] iptables manpage: Update DNAT target

[PATCH] iptables manpage: Update DNAT target

[Mart Frauenlob]

[-- Attachment #1: Type: text/plain, Size: 212 bytes --]

Hello,

this patch renames libipt_DNAT.man to libxt_DNAT.man thus informing 
about the IPv6 version.
Also the list of valid protocols for port mapping is updated to:
tcp, udp, dccp and sctp.


Best regards

Mart

I'm very sorry, I messed up the author lines, resending.

Applied, added this to the end of the manpage:

IPv6 support available since Linux kernels >= 3.7.

Thanks.
