Act as a Personal Firewall that allows internet access by application. Work with an Operating System other than Linux (version >= 2.4.0) Act as a Proxy (although it can be used with a separate proxy such as Squid or Socks). Do content filtering: HTTP - better to use Squid and Dansguardian for that. Email -- Install something like Postfix on your firewall and integrate it with SpamAssassin , Amavisd-new and Clamav Set up Routing (except to support Proxy ARP) — Shorewall 2.3.3 and later CAN be used to set up complex routing provided that your kernel and iptables include ROUTE target support. Do Traffic Shaping/Bandwidth Management (although it provides hooks to interface to Traffic Control/Bandwidth Management solutions) Configure/manage Network Devices (your Distribution includes tools for that).

Shorewall generally does not contain any support for Netfilter Patch-O-Matic-ng features or any other features that require kernel patching -- Shorewall only supports features from released kernels except in unusual cases.
