Why Untangle Firewall
I have been using ISA Server for past 7 years. But it was not fulfilling my requirements and it was expensive too. I wanted to to for a box which must be all in one, but here was again issue of priing.
Luckily I looked for opensource, which helped me to use my existing extra computer (Desktop PC) and use this as firewall.
I looked for many Opensource Firewall devices and applications but I found untangle had all the options and best.
I started using Untangle in 2007, and and I didn’t face any issue in past 3 year. I thought sharing my experience would help many.
