Plesk 12.x / Linux :: Firewall Not Generating Rules Correctly
Aug 17, 2014
I am using the plesk firewall and trying to set up SSH rule which only allows from my IP but deny from everywhere else. In previous versions this worked fine by adding an ip selecting Allow from selected sources, deny from others and the icon in the rules would be orange with the lines
allow incoming from xxx.xxx.xxx.xx
Deny incoming from all others
However this no longer works as the deny from all others is not appearing and is not being generated in the iptables by plesk.

When I modify rules using the firewall panel it is not generating rules correctly when selecting allow from selected sources deny from others.

When I deny all other traffic for the "System policy for incoming traffic" to secure the server by only allowing the explicit ports I've requested to open, my server stops operating correctly.
It appears when I set the "System policy for incoming traffic" to deny, it appears to be disrupting various functions such as web traffic over ports 80/443, FTP, SSH, they either work extremely slow or don't work at all.
I brought this up with my Plesk license provider and they stated that the Plesk firewall doesn't add any tracking for ephemeral ports, therefore if you set the policy to drop for incoming/outgoing, it's not going to allow proper TCP communication since the return socket can't be opened. Also that the firewall is an explicit deny system rather than explicit allow based system.
Am I doing something wrong? All I want to do is to block all ports other than the ones I've set to allow. Is this how it is supposed to work?

Applying Plesk firewall changes? I make my change, apply and get to:
Status: Applying in progress. If your browser shows connection error messages, or if this screen does not disappear in more than 30 seconds, go to previous page.
And there things stay. Going back to look at the firewall I can see the change haven't been applied, and going to apply just results in the same. No error, just no anything. It also took numerous attempts to get firewall modification to be swtich on although finally at about the eighth attempt changes were enabled. Only now I can't apply them ...

I am running a CentOS 6.6 (Final) with Plesk 12.0.18 Update #27 on my dedicated server. I was advised to upgrade my server to one that has a SSD due to better performance. What they failed to tell me was that I would need to perform additional configurations so that Plesk stores the subscription files in the /HDD-var/ directory and NOT the /SDD-var/ directory. Current server
Here are my questions:
1. How difficult would it be (I am a quick learner and can follow exact steps or directions very well) to make Plesk store the files on the HDD rather than the SDD?
2. Is this something I should undertake or is this very difficult to do?
3. If I perform these changes, will they revert to the old way if I perform Plesk updates? Or will the changes I make become permanent?
SSH: df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md1 4.0G 916M 3.1G 23% /
/dev/mapper/ssd-usr 3.9G 1.9G 1.8G 51% /usr
/dev/mapper/ssd-var 3.9G 3.7G 2.7M 100% /var (Plesk is storing data here)
/dev/mapper/ssd-home 3.9G 792M 2.9G 22% /home (Would also like this data to be on the HDD)

I have a Centos 6 server with Heart Internet, who yesterday had an issue with the issue and once back online have been struggling til now getting the mysql service working correctly again and have now refused to provide any further support and redirected me here.
I was following this article here: [URL] ....
I've gotten to point 4. "~# mysqldump -uadmin -p`cat /etc/psa/.psa.shadow` -A | sed '1iSET FOREIGN_KEY_CHECKS = 0;' > /root/dumpall.sql" however it's saying "got error: 145: table './avenue141_dabs/av_options' is marked as crashed and should be repaired when using LOCK TABLES and any attempts made to get into the DB to repair is giving me "error: 1045: Access denied for user 'root'@'localhost' (using password: NO)
This issue is urgent as we have a few websites on this server which use mysql databases for their website.

I am running Plesk 11.5.30 Update #44, Postfix 2.8.14 and Spamassassin 3.3.1 on a Red Hat Enterprise Linux Server 6.5 server. I am looking to update the rules within Spamassassin. I have had a bit of a look and see that a crontab has been created but its a bash script with a comment saying it has been disabled by psa-spamassassin package (/etc/cron.d/sa-update).
Code:
#!/bin/sh
# This task was disabled by psa-spamassassin package
exit 0
Is there a reason why it has been disabled by Plesk? If I update the rules, will it break something?
I have recently added into Postfix RBLs to reduce the amount of SPAM my customers is getting and this is my next step in a list of things that I would like to change.

I have these problems since version 11.5. Now I have installed version 12 on centos . FTP works fine and is super fast and speedy until i enable PLEK FIREWALL, I also tried to add passive port range 60000-65534 to Plesk Firewall rules.
But nothing works.
It takes like 10 times longer to Login + List Files + Make changes using FTP. We applying changes via FTp and its very slow. We can use plesk file manager but its very inconvenient way for quick file uploads and changes.

I already posted this as a bug report and now wanted to inform other users.
Starting with Plesk 11.5, the file "/opt/psa/var/modules/firewall/firewall-emergency.sh" contains the following line:
Code:
rm -f /opt/psa/var/modules/firewall/active.flag
That line stems from updating
Code:
Preparing to replace psa-firewall 11.0.9-debian6.0.build110120608.16 (using .../psa-firewall_11.5.30-debian6.0.build115130819.13_amd64.deb) ...
Unpacking replacement psa-firewall ...
Now, when you stop the firewall, you cannot start it again, cause deleting the active.flag disables the firewall:
Code:
# ll /opt/psa/var/modules/firewall/active.flag
-rw-r--r-- 1 root root 0 2013-11-26 09:22 /opt/psa/var/modules/firewall/active.flag
# /etc/init.d/psa-firewall stop
psa-firewall: firewall successfully disabled
# ll /opt/psa/var/modules/firewall/active.flag
ls: cannot access /opt/psa/var/modules/firewall/active.flag: No such file or directory
# /etc/init.d/psa-firewall start
psa-firewall: service is disabled
You then have to manually "touch" the active.flag to be able to start the firewall again. A workaround is to remove the line:
Code:
sed -i 's:rm -f /opt/psa/var/modules/firewall/active.flag::' /opt/psa/var/modules/firewall/firewall-emergency.sh'
I really hope that Parallels fixes this asap, as normally you won't notice that the firewall is not active when every works fine (nothing is blocked) and Plesk still shows all the rules.

Plesk Firewall has no effect on IPv6?
I am writing today regarding the Plesk Firewall. It seemed to be pretty handy for quickly blocking troublesome users from *replace-with-whatever-IP-block-is-giving-you-trouble*. Yet I am unable to block IPv6 addresses, and the fire wall seems to let some blocked IPv4s right in. I did not see any distinction as to v4 or v6 in the Firewall dialog for adding custom rules, so...
The question is...
(1) Is the Plesk Firewall *supposed* to apply rules to IPv6 by default?
If yes...
(2) Is there a setting or a switch that has to be configured for this to work?
If yes...
(3) Where are said configuration options located?
Okay, when I run /sbin/ip6tables -L (CentOS) I get output that resembles the iptables (no 6) output, only... what, converted to IP6? Not sure. Example output:
DROP tcp ::ffff:31.0.0.0/104 ::/0 tcp dpts:1:10000
In that particular instance I added a drop for the 31.0.0.0/8 block (using the Plesk Firewall interface), in order to create the script that's loaded into iptables (and ip6tables as well, apparently) when one elects to "Apply Configuration". It worked great, executed perfectly, and the iptables output list output looked to be (and remember, I have grossly insufficient background knowledge in this area) accurate.
Yet at the time of this writing I can see via live traffic monitor that an address in the 31.0.0.0/8 block (IPv4) is pounding away at a website. This is curious, as the live traffic monitor indicates an IPv4 address. So... can an IPv4 address be detected and recorded from a host that is only able to connect via IPv6? While an interesting question, I was more concerned with just blocking the IPv6 address and get more academic with it later.
But this raises another question; why would Plesk populate ip6tables and not provide an interface to actually submit IPv6 addresses.

Running plesk 12.018 on OpenSUSE 13.1
What causes the firewall to change / reset itself periodically? I enabled the plesk firewall, but some time later it is reset itself and switched to the opensuse firewall (completely different rule set, which blocks most of the ports).
I then disabled the plesk firewall and loaded my own iptables rule set via iptables-restore command. However a few hours later, it also gets reset to the opensuse firewall. The std. opensuse firewall closes most of the ports, so then our email is blocked.
I would like to permanently switch off any plesk handling of the firewall and manage the iptables myself. How to do this?
I also have fail2ban running and defined my own jail.local files.

After upgrading to Plesk 12 the FTP connection has become very slow. Mode Security, Fail2Ban and Plesk Firewall have been enabled, the security is set to force sFTP and maximum security and in /etc/proftpd.d/ a conf file has been added to set the passive ports that have been opened in the Plesk Firewall (60000 to 62000)
Turning off the Mod Security does not solve the slow connection.
What can we do to detect the cause of the problem?

I have some issues with the plesk firewall:
1. Emails are not delivered:
From some reasons, plesk is blocking incoming 25 port (in plesk shows opened, but it's not)My emails are delivered trough port 25, after doing some tests ( i've sent some emails to an email account hosted in the server) there was no email in the roundcube inbox! All emails were blocked...
a) Firewall was blocking the port 25 on server restart.
b) I have succesfully unblocked it from plesk manager -> tools -> edit/change -> even if i didn't change anything, i saved the "changes" and in my roundcube inbox i recived all the test emails.
c) In /var/log/maillog there is no error.
2. Passive FTP gets blocked in the same way, to successfully connect FireFTP on passive mode i need to repeat 1.b steps even if i've created a special rule to prevent the blocking, opening 49152-65534 ports and set PassivePorts 49152 65534 in /etc/proftpd.conf
The issue appears randomly, because in the last 5 days i didn´t restart the server, the last time i checked it worked. Today, without touching anything, firewall blocked my passive FTP and I had probmels reciving emails from gmail, yahoo etc...
