Re: [PLUG] Firewall Check

Could you share that Shoreline script?



Do you mean the resulting iptables rules or the multiple Shorewall config files? I don't want to paste *that* many iptables rules to the list. The "policy" and "rules" files seem to be the most important Shorewall files. These are the names of the Shorewall files that I've modified so far:


*policy*
zones
interfaces
tunnels
maclist
masq

The modifications within each file, with modifications, follow:

policy:
#SOURCE         DEST            POLICY          LOG LEVEL       LIMIT:BURST
loc             all             ACCEPT
wlan            all             ACCEPT
vpn             all             ACCEPT
# If you want open access to the Internet from your Firewall
# remove the comment from the following line.
fw              all             ACCEPT
net             all             DROP            info
all             all             REJECT          info
