How to Configure Dynamic DNS in OPNsense

How to Configure Dynamic DNS in OPNsense

Have a non-static public facing IP address and want to utilize dynamic DNS?

If you have software/services running on your local network that you want to remotely access, you may have encountered a situation in which your IP address changes periodically. Many ISPs do not assign static IP addresses to non-business accounts especially for IPv4 addresses because they are extremely limited and have technically been exhausted for some time now. When your modem stays connected for a long period of time with an ISP, it is possible your IP address will not change often.
How to Configure DHCP When Using VLANs in OPNsense

How to Configure DHCP When Using VLANs in OPNsense

Are you new to VLANs and want to configure DHCP in OPNsense?

When you are new to creating VLANs on your network, you may wonder about the necessary steps in order to create a properly functioning VLAN. If you set up OPNsense with one WAN and one LAN interface, it is kind enough to set up a basic configuration for the LAN interface with DHCP enabled and a single firewall rule that allows access to the Internet. You can consider this configuration to be a “flat” network, which means that every device is on the same network and can communicate.
Disable Logging into OPNsense as the Root User

Disable Logging into OPNsense as the Root User

Allowing root user logins is not normally a good idea...

After installing OPNsense, the default login is the root user. Logging in as the root user is generally not advised because the root user has full access to files and processes. Linux users, for instance, are asked to create a separate user account upon installation. The user can then use the sudo command to elevate privileges to perform administrative tasks. If the user’s account is compromised, in theory the root account is still protected (assuming there is no privilege escalation vulnerability being exploited or the password has been discovered).

Accessing Your Home Network with Your Very Own OpenVPN Server on OPNsense

Accessing Your Home Network with Your Very Own OpenVPN Server on OPNsense

Want to access your home network remotely and securely?

A VPN server can provide an encrypted connection to your home network. It is a great way to remotely access your network since it provides a high level of security. Once you are connected to the VPN server, you essentially become a part of the network in which you are connected. This is different than using an SSH server because you are not directly connecting to a single machine on your network.
