Shorewall 2.1.0

----------------------------------------------------------------------
Problems Corrected since 2.0.3

1)  A non-empty DEST entry in /etc/shorewall/tcrules will generate an
    error and Shorewall fails to start.

2)  A potential security vulnerablilty in the way that Shorewall
    handles temporary files and directories has been corrected.

3)  Two problems with logging NAT rules (DNAT and REDIRECT) could cause
    startup failures.

-----------------------------------------------------------------------
Issues when migrating from Shorewall 2.0 to Shorewall 2.1:

None.

-----------------------------------------------------------------------
New Features:

1)  ICMP packets that are in the INVALID state are now dropped by the
    Reject and Drop default actions. They do so using the new 
    'dropInvalid' builtin action.
