open source replacement for PIX needed
Posted on 2006-11-22
I have a PIX firewall
Hardware: PIX-515, 64 MB RAM, CPU Pentium 200 MHz
Flash i28F640J5 @ 0x300, 16MB
BIOS Flash AT29C257 @ 0xfffd8000, 32KB
For financial reasons my boss wants it replaced with an open source one.
i want to know the following
1. Should i buy a server hardware like dual core machine with 4 Gb memory etc or just buy a dell machine and install the firewall on it.
2. The PIX right now has three DMZs and a setup for VPN connections so that others can connect to it remotely. so i would need a firewall which has DMZ support and VPN support as well.
3. What the are the various different good software based firewalls in open source world. i know about iptables and some others but is there any which provides the same facilities as PIX in terms of features. it would be great if the command line configuration is also the same.
