NAT configuration

NAT is a network address translation mechanism that translates packet IP addresses. NAT allows servers on a local network to work with servers on an external network.

If the server with FASTPANEL® has a private IP address, and NAT is configured on the local network, to ensure correct work with DNS domains, websites and mail services, you must configure the server's private and public IP addresses mapping.

To set up IP addresses mapping:

  1. Open the left-side menu → "IP management" → "IP mapping"

    IP management menu in FASTPANEL

  2. Click "Add"

    Linked IP settings in FASTPANEL

  3. For the local IP addresses, enter the corresponding Public IP address

    IP settings for FASTPANEL behind NAT

  4. Click "Save"

After configuring the address mapping, internal IP addresses will be converted into external IP addresses when creating DNS domains.

List of ports for forwarding​

For the correct operation of the main services, you need to configure forwarding for the following ports:

  • FASTPANEL: 8888, 7777

  • FTP: 21, 65000-65500

  • SSH: 22

  • SFTP: 2222

  • HTTP, HTTPS: 80, 443

  • IMAP, IMAPS: 143, 993

  • POP3, POP3S: 110, 995

  • SMTP, SMTPS: 25, 587, 465

  • DNS(if bind9 is used): 53

Other services, such as MySQL, typically only run on local IPs and do not require public access.
