Firewall for port 8443

C

Hi,

I had a firewall behind my Plesk Server. By default i block all incoming.. only accepting port HTTP/HTTPS/SSH/8443 which is for plesk.

But i cannnot seems to go to the login page of the plesk server.

Is there any other ports i should open in order the thing to work? Any advice?


ThANKS a million!

I open up all this port for my firewall
same as the link you send me. But

#20 ftp-data
#21 ftp
#22 ssh
#25 smtp
#53 dns (TCP and UDP)
#80 http
#106 poppassd (for localhost only)
#110 pop3
#113 auth
#143 imap
#443 https
#465 smtps
#990 ftps
#993 imaps
#995 pop3s
#3306 mysql
#5432 postgres
#8443 plesk-https
#9080 tomcat
#5224 (outgoing) plesk-license-update

I still cannot access plesk admin through 8843.

i only can access if i open up all the above and a range of 40000 to 50000 tcp ports. Why? is there anything i miss out?
 
It's 8443, not 8843 (just double check that, maybe you made a typo). Is the psa service actually running?

Those high ports are not needed for access to the Plesk web interface, but may be needed for FTP access (read up on active/passive FTP).
