This section provides the steps to reconfigure FQDN and IP addresses in the system, IPv4, IPv6 only, and dual stack are supported.

Prerequisites

DNS servers should be able to resolve the FQDN to the IP addresses that will be set to the Airgap Appliance.

Procedure

1. Login the TCA Airgap Appliance via SSH admin account then switch to root with su to use agctl command.
2. Edit /usr/local/airgap/scripts/vars/user-inputs.yml using the following command:

   vi /usr/local/airgap/scripts/vars/user-inputs.yml

3. Update the following settings. For more information on the parameters, see Agctl CLI Command Reference:

   server_fqdn: <full qualified domain name of the airgap appliance>
   ip_family: <could be "ipv4", "ipv6" or "ipv6,ipv4"
   dhcp: <True or False>
   static_ip: <ip addresses seperated by comma> 
   default_gw: <gateway ips seperated by comma>
   dns_servers: <dns server IPs seperated by comma>

   Examples:

   IPv4 Static

   server_fqdn: airgap.example.com
   ip_family: ipv4dhcp: False
   static_ip: 192.168.100.100/24 
   default_gw: 192.168.100.1
   dns_servers: 192.168.100.253

   IPv6 Static

   server_fqdn: airgap.example.com
   ip_family: ipv6dhcp: False
   static_ip: fc00:192:168:100::100/64 
   default_gw: fc00:192:168:100::1
   dns_servers: fc00:192:168:100::253

   Dual Stack

   server_fqdn: airgap.example.com
   ip_family: ipv6,ipv4
   dhcp: False
   static_ip: fc00:192:168:100::100/64,
   default_gw: fc00:192:168:100::1,192.168.100.1
   dns_servers: fc00:192:168:100::253,192.168.100.253

   IPv4 DHCP

   server_fqdn: airgap.example.com
   ip_family: ipv4
   dhcp: True

4. Save and run agctl deploy command to apply the settings.
