[expert] Shorewall

[Joseph Loo]

I recently installed a fresh copy of Mandrake 9.1 and included the 
shorewall firewall. I have a modem hookup. When I try to ping a site 
e.g. www.ibm.com the system never seems to respond. It looks like the 
firewall is preventing something from happening. I have enable the 
shorewall to allow everything and none. If I have none, I can ping 
specific addresses with no problems. It seems to me that the program is 
not allowing the standard dns client information to either broadcast or 
receive.

Note, I also found out that the local systems tied via an ehternet 
connection will not allow me to ping any addresses. It seems to me that 
the system allows the ping but does not allow the responds to come back. 
This is true when everything is blocked but it allows when nothing is 
blocked.

At this time I have 2 problems, the firewall can not distinguish the 
local network versus the internet (I use mandrak configuration tool to 
add the modem into the syste but no such luck). and the rules needed to 
allow the internet to communicate.
