You may use IBM firewall:
It offers packet filtering (Time based filters), socks, transparent proxy
for tlenet and ftp, NAT, VPN to networks or to IPSec client, Mail proxy,
HTTP proxy, realaudio proxy, vdolive proxy and icq proxy, limited shell
access to firewall, DNSsplitting, Enterprise firewall management, pager
warning support, java based management, alongwith others which does not come
to my mind in hte first sight.
If you have some specific needs please contact me to ask.
