2.31. Outgoing connections

Outgoing connections are calls from hosted sites to third-party servers in the course of their work.

Outgoing connections are always sent from direct server IP... Please note that when a request is sent to an address that has IPv6, the connection will be made over it, since it has a higher priority than IPv4.


Outgoing connections are automatically blocked if malicious code is detected by our antivirus... The block is lifted automatically after clearing the hosting account and re-checking. You cannot remove the lock without removing the malicious code.

You can view information and open ports for outgoing connections in the section "Hosting → Outgoing connections»:

At the top of the section there is a block where you can select the required date for analysis from the list and filter connections by IP, as well as a button that allows you to block absolutely all outgoing connections for a hosting account: The list displays only the dates when outgoing connections were committed. The dates for which there were no such connections will be absent from the list.

The list of all recorded outgoing connections looks like this:

  • «Date"- the date when the connections were registered.
  • «IP"- the address to which the appeal was made.
  • «Protocol"- the protocol used for the connection.
  • «Port"- the port to which the call was made.
  • «Action"- connection status:
    • «ACCEPT"- the connection was allowed.
    • «REJECT"- the connection was rejected.
  • «Number of connections»- the number of connections with the specified address on the mentioned port for the selected date.
  • - button for blocking connections to the specified IP.

At the bottom of the page, graphs are displayed showing the number of recorded outgoing connections by day over the last 30 days.

Important points:

  • You can open no more than 10 ports... If that's not enough, it's worth considering the use case VPS or dedicated server without our administration.
  • Ports are opening TCP only... It is impossible to open ports for UDP traffic within virtual hosting.
  • Ports are not opened separately for each site, but in general for a specific hosting account.
  • A number of standard ports cannot be opened on the hosting, since they are reserved or open by default and you do not need to reopen them:
    • Ports open by default: 21, 43, 53, 80, 123, 161, 443, 587, 465, 1433, 3306, 4343.
    • Reserved ports that cannot be opened: 20, 25, 113.
    • The rest of the ports must be opened manually.

To open the necessary ports, specify them in the field “Open outgoing ports»: The changes will take effect approximately within 15 minutes.

All connections for which manual blocking is set are displayed in the block "Blocked outgoing connections»:

Using the button "Add note»You can add an arbitrary note to each blocked connection for convenience.

To unblock connections, use one of the following methods:

  • Or use the button with a red cross next to the required entries.
  • Or check the boxes next to the required entries and click "Delete rules».
