I've read the archives, and I cannot find out how to allow ping to pass outside
the local (LAN) subnet.

The 2 things I want to do are:
1) Be able to ping websites (eg 'ping www.google.com' and 'ping m0n0.ch')
2) Reply to a ping sent at my address (eg. someone else types 'ping
my_ip_address'  and they get a response)

Right now I can ping other machines inside the LAN, and I can ping the m0n0wall,
but I cannot ping websites.  Coming from the WAN, no ICMP echo is returned.

Thanks for all the help.
