FC5 iptables issue



A while back I noted some unexpected entries being allowed through
iptables in FC4 on a clean install.  I filed a bug report on this
#181397.

It appears that FC5 still has similar issues.

3    ACCEPT     esp  --  0.0.0.0/0            0.0.0.0/0
4    ACCEPT     ah   --  0.0.0.0/0            0.0.0.0/0
5    ACCEPT     udp  --  0.0.0.0/0            224.0.0.251         udp
dpt:5353
6    ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0           udp
dpt:631
7    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp
dpt:631


I don't see any reason that  want to allow UDP traffic to port 5353.
And I don't believe I want to allow traffic to port 631, no reason for
anyone to be accessing the cups configuration from the network.

This was a clean install of FC5.
