Shorewall Cannot:
Be used to filter traffic through a Layer 2 Bridge
Act as a "Personal Firewall" that allows internet access
by application.
Be used with an Operating System other than Linux (version
>= 2.4.0)
Do content filtering:
HTTP - better to use Squid
for that.
Email -- Install something like Postfix on your firewall and
integrate it with SpamAssassin
and Amavisd-new.
In Addition:
Shorewall does not contain any support for Netfilter Patch-O-Matic
features -- Shorewall only supports features from released kernels.
