Hi Everyone,
My company is putting me in charge in implementing a Firewall for our
company. One guy in my networking group is recommending PIX Firewall.
Furthermore, he also recommends a Cisco Web-caching engine. His reason
is that not only Cisco is good Firewall but it also provides VPN
connectivity to our remote sites. Myself, on the other hand, would
like to implement Linux-based OS firewall along with FreeS/WAN VPN
features set. My reason is that a linux firewall can provide everything
a Cisco PIX does and even more. In term of hardware, the linux Firewall/
VPN/IPSec box will be running a dual-processor (800MHz) with 1GB of RAM.
I just feel that I can get a lot more for the amount that we are going
to spend with linux than with Cisco PIX. I also feel that I tweak the
source code on the LINUX kernel to increase the performance and security.
Also, instead of purchasing the Cisco web-caching engine, I am thinking
of building another linux box that will be running squid (web-caching)
server. Don't get me wrong, I think Cisco has a lot of good products
in the area of routing; however, I just don't think it is necessary to
throw away money at Cisco when I know that Linux or BSD can do the same
job that PIX and Cisco web-caching engine do but for much less and also
I can control the source code. Has anyone has experiences with both
the Linux/BSD, Squid and Cisco PIX, Cisco web-caching engine so that
you can give advice on what I should do. I am open to your suggestions.
Many thanks.
Sean
