Kerio 2.1.5 won't save changes to rules configuration file. Help!

Threaded View
I've been using Kerio PFW for years and have developed a sizable set
of rules in my persfw.conf file.

Now I can't save changes, not even deletions.

I suspect the persfw.conf file might have become corrupted at some
point in the past. I tried using a two-month old backup of the
persfw.conf file, but same problem.

The persfw.conf file is encrypted, so I can't use it for guidance in
building a new file.

I tried using a tip posted some time ago (by Servus - B.) about
removing encryption from the file by adding the following to the

[HKEY_LOCAL_MACHINE\\Software\\Kerio\\Personal Firewall]

But this doesn't seem to do anything with Kerio PFW 2.1.5.

I've tried deleting the file while PFW is running; when I close down
the program it recreates the persfw.conf file, but the newly created
one seems to have the same problems.

I've uninstalled the program, cleaned the registry, and reinstalled.
Same problem when I try using one of my old persfw.conf files. Of
course I've checked that nothing has been protected by a Read-Only,
Hidden, or System attribute.

I'm running out of ideas. Any suggestions? Has anyone else encountered
this weird, frustrating problem?

If I have to start rebuilding all my firewall rules, I might as well
consider changing to another program. Anyone care to make a

I'm running W98SE with DSL and have BlackICE running as a second

I've found that BlackICE and KerioPFW do different things, are
compatible with one another, and perhaps offer me a little greater
protection than running either one alone. That is, my configuration
mistakes in one program (or program limitations) may be compensated
for by the other. No noticeable performance problems, even on an old,
slow machine.

I use that, without difficulty.  Perhaps you aren't doing it right?

To avoid confusion I would suggest that you try getting that to work
with a fresh rule set first, before trying it again on your problem

Thanks Dave for the wise advice. With your encouragement I looked
further into the ruleset encryption problem and found detailed
instructions for removing encryption at:

This site primarily provides advice on constructing Kerio rulesets.

Turns out that the hex value I had entered was corrupt or invalid.
Looked fine using Norton Registry Editor. But W98SE's regedit
immediately flagged the value as invalid. Interesting ...

So I now finally have an unencrypted ruleset file to work with.

I quickly scanned the unencrypted file and don't see any corruption,
but it's late (that is, sun is about to rise) and time to stop.

I did find some discussion on a user discussion board about the
problem I'm having saving ruleset changes:

Apparently there are some bugs in 2.1.4 and 2.1.5 which may cause
problems with large rulesets. Some suggested making only one change,
then saving the file. Ugh! It will take me forever to work this way!

I'll have to experiment. I just upgraded from dial-up with Slipstream
accelerator to DSL. That means I can now delete a whole lot of
redundant rules which Slipstream required. It may be faster and easier
to edit the ASCII file. Perhaps my problem will fade away when the
ruleset file is smaller. (It's about 90K encrypted; slightly larger

Thanks again for your prompt help!

I never mess with the Kerio system files and save backup .conf files
to my data area and/or a floppy, and I've never had any problem
restoring them. The file size is typically 15k.
