[pve-devel] [PATCH firewall] fix #2721: remove reject tcp 43 from default drop and reject actions

[Lorenz Stechauner]

first, '43' is a typo, it should say '113' (if it really is like
legacy shorewall [0]). this tcp port corresponds to the ident or
authentication service protocol.

second, nowdays this reject is not included in shorewall anymore.
furthermore it would make no sense to reject specifically this
one port.
