Ok, I did this:
]# iptables -L OUTPUT -n -v
Chain OUTPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
10175 4066K ACCEPT all -- * lo 0.0.0.0/0 0.0.0.0/0
0 0 DROP !icmp -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID
24541 1478K fw2net all -- * eth0 0.0.0.0/0 0.0.0.0/0
4286 336K all2all all -- * eth1 0.0.0.0/0 0.0.0.0/0
0 0 Reject all -- * * 0.0.0.0/0 0.0.0.0/0
0 0 LOG all -- * * 0.0.0.0/0 0.0.0.0/0 LOG flags 0 level 6 prefix
`Shorewall:OUTPUT:REJECT:'
0 0 reject all -- * * 0.0.0.0/0 0.0.0.0/0
Being a complete newbie at this, it appears that shorewall is blocking
ALL pings. Exactly how should I enable bidirectional pings (and
everything else for that matter) within my local network, and still
block only those pings coming from outside, (from the Internet)? I've
never had to manually config shorewall, and haven't a clue what
ccommand to use, or where to put it to make it permanent.
