[cobalt-users] Firewall/IPChains w/ IPADDR Rule

[David <david_dean@xxxxxxx>]

Can anyone advise me with the following regarding the setup of a firewall
rules with IPChains? 

My rule-set is configured as:

EXTERNAL_INTERFACE="eth0"		# Internet connected interface
LOOPBACK_INTERFACE="lo"			# or your local naming convention
IPADDR="any/0"				# your IP address
ANYWHERE="any/0"			# match any IP address
NAMESERVER_1="any/0"			# everyone must have at least one

The information at
http://www.linux-firewall-tools.com/linux/firewall/index.html says to
configure the IPADDR as:

|IPADDR = This is the IP address of your external interface. 
|It's either a static IP address registered with InterNIC, 
|or else a dynamically assigned |address from your ISP 
|(usually via DHCP).

But when I set the script (IPADDR) to the main IP for my server, it freezes
the box. If I use the "any/0" entry, all is okay.

My Question is what are the proper IPADDR setting(s) if not the main IP of the
box (for optimum protection)? Should this value be set to "any/0" or is it
possible to set this to just the IP's in *use* on the box?

Thank you in advance for any insight to this dilemma.

David
