I have searched on the Internet for a portable firewall
but there was not much success, i found only one program which
worked somewhat that is X-DcFirewall which is opensource as well
but there is a problem with DcFirewall that the longer it
runs the more system becomes sulligish i think it has some
memory problem, can someone fix this problem.

DcFirewall can be could here -
http://sourceforge.net/projects/dcfirewall

And if that is not possible can someone tell whish are the
best portable firewall.

I've been looking for a portable firewall solution since I got started on the site. I think Magibon points out why we don't have one, but it seems like such a thing would be possible via a local proxy or something similar. The only possibility I've seen lately is a front-end for the Win 7 firewall settings configuration mentioned by Klon

The closest thing in the database would probably be PeerBlock http://www.portablefreeware.com/index.php?id=1559 or turning up Window's security settings using XPY or XP-AntiSpy.

Portable firewall:
-ghostwall
-sterjofirewall
-windows7firewallcontrol

Thanks for that - hadn't seen this before

Windows 7 Firewall Control - Vista and above, no 64-bit portable version
site does claim a portable version http://sphinx-soft.com/Vista/order.html or http://www.softpedia.com/get/PORTABLE-S ... able.shtml

The others:

* ghostwall - couldn't find any indication it's portable ... is there a config trick?
* sterjofirewall - payware

sterjofirewall does provide a free version of their portable firewall : http://www.sterjosoft.com/portable-firewall.html

Ok, I'm kind of running late here, but logged in Just to mention this.
Unless there has been some Major(!) change to Ghostwall in the last year or so, its Not portable and its fricken Hard to get rid of.
(I cant find the post, but I'm sure it was asked about in the past year and I didn't see an update to the webpage or program then.)

I've posted about it when was been talked about here before:
viewtopic.php?p=2142
Yes, it's an old thread, But, I havn't seen any updates to the program since. Though, like I said, I havn't checked in about the past year.
EDIT: Softpedia says This about Ghostwall: "Last Updated: September 30th, 2005, 08:56 UTC". So I'm going to go with "Still Horrible" and "Not Portable."


and i use:
http://www.softpedia.com/get/Security/F ... wall.shtml

It works pretty well, even though it writes setting to the registry, I think it remembers the last used config.
My only problem with it that it doesnt keep logs.

Some updates. Sterjo firewall is freeware now. I'm considering going for Tinywall which is not portable, but at least it uses the built-in windows firewall. Patching windows system files reminds me of system unstability.
