Re: Application level firewalls/proxies

Hi there,

had the same question but did not find something in the style of 'ZoneAlarm'
but for Linux.
I solved it this way:
1- I have a Linux server installed that is my interface to the internet (via
ADSL)
2- it plays the role of router and firewall using ipchains, managed by the
Webmin 'firewalls' module which i configured to my needs. No direct routing
between inside and outside is allowed.
3- the application level firewall is obtained by putting in an application
that links the inside with the outside: the squid proxy for html,
fetchmail/sendmail/fetchnews etc. I checked this with the nessus hacking
tool; it could not find any security hole...
4- On top of this I added the antivirus software from http://www.antivir.de/
to scan files and the mail

All of this for free and legally.
(fyi I'm using SuSE 7.1)
