Plesk firewall keeps blocking port 25 and passive ftp ports

[PDSolutions]

Hi,

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...

***
I have: Parallels Plesk v12.0.18_build1200140606.15 os_SuSE 13.1

Thanks,
Eugen P.

@PDSolutions Check which services are running on the background and check your (Plesk) Action Log and files for recent changes.
Also Check outgoing network traffic.

Have a look in the extentions management. There should be a tool called Webserver Configurations Troubleshooter (version 2.0).
Maybe you can use a Log Search there and find possible clues to what might be wrong.

When we setup our server with Plesk 12 and CentOS 6.6 we could not manage the firewall from within Plesk at all for some reason.
I had to use iptables (firewall) in order to accept specific ports. Everything worked as it should and permanently.

Anyway i also would like to see other people their replies.

Hi,

Thank you Noturns, but i found here a solution http://talk.plesk.com/threads/plesk-12-firewall-problem-stops-working.311353/.
I disabled SuSe firewall, wich was blocking all ports, and rebooted the machine. I have already 2 days without any issue!.

Thanks again for your quick response.
Best regards,
