Configuring network settings

Configure GitHub Enterprise Server with the DNS nameservers and hostname required in your network. You can also configure a proxy server or firewall rules. You must allow access to certain ports for administrative and user purposes.

  • Configuring the IP address using the virtual machine console

    By default, GitHub Enterprise Server retrieves network settings via the dynamic host configuration protocol (DHCP). If your platform supports it, or if DHCP is unavailable, you can also configure the network settings using the virtual machine console.

  • Configuring DNS nameservers

    GitHub Enterprise Server uses the dynamic host configuration protocol (DHCP) for DNS settings when DHCP leases provide nameservers. If nameservers are not provided by a dynamic host configuration protocol (DHCP) lease, or if you need to use specific DNS settings, you can specify the nameservers manually.

  • Configuring a hostname

    We recommend setting a hostname for your appliance instead of using a hard-coded IP address.

  • Validating your domain settings

    Ensure that your domain settings are properly configured before booting up your GitHub Enterprise Server instance for the first time.

  • Configuring TLS

    You can configure Transport Layer Security (TLS) on your GitHub Enterprise Server instance so that you can use a certificate that is signed by a trusted certificate authority.

  • Enabling subdomain isolation

    You can set up subdomain isolation to securely separate user-supplied content from other portions of your GitHub Enterprise Server appliance.

  • Configuring an outbound web proxy server

    A proxy server provides an additional level of security for your GitHub Enterprise Server instance.

  • Configuring built-in firewall rules

    You can view default firewall rules and customize rules for your GitHub Enterprise Server instance.

  • Network ports

    Open network ports selectively based on the network services you need to expose for administrators, end users, and email support.

  • Using GitHub Enterprise Server with a load balancer

    Use a load balancer in front of a single GitHub Enterprise Server instance or a pair of instances in a High Availability configuration.
