2.31. Outgoing connections

Attention!

All outgoing connections are automatically blocked in case of detection of malicious code by our antivirus... The block is also lifted automatically after clearing the hosting account and re-checking. You cannot remove the block without removing the malicious code.

Note

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 calls from hosted sites to third-party servers in the course of their work. You can view the information and open ports for outgoing connections in the section "Hosting → Outgoing connections»:

At the top of the section, you can select the desired date for analysis from the list and filter connections by IP, as well as manually block absolutely all outgoing connections for the hosting account: The list displays only the dates when outgoing connections were committed. The dates for which there were no such connections will not appear in 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 request was made, its PTR record and brief information about its owner.
  • «Protocol"- the protocol by which the connection was made.
  • «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.
  • Lock button - blocking connections to the specified IP (the address will be added to blocked connections).

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 do not need to be reopened:
    • 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 “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»:

  • «IP"- blocked address, its PTR record and brief information about its owner.
  • «Protocol"- the protocol used to block connections.
  • «Port"- port to which connections are blocked.
  • «Notes"- button"Add note»Allows you to add an arbitrary note to each blocked connection for convenience.
  • Button with a lock - unblocking connections to the specified IP (you can also unblock connections by setting the checkboxes opposite the required entries and clicking "Delete rules»).

Button "Block IP"Allows you to manually block outgoing connections to a specific IP with an indication of the port and protocol.
