Auto-Mount NAS When Your Mac Comes Home

1Why Network Trigger Rules Matter

Manually mounting your NAS every time you open your Mac gets old fast. GoMount's network trigger rules solve this by watching your network environment and automatically connecting your NAS drives the moment you enter a trusted zone. No clicks, no commands, no remembering IP addresses.

This guide explains how GoMount detects your location, how to configure the two detection methods, and how to combine them for maximum flexibility. By the end, you will have a setup that just works: walk into your house, open your Mac, and your NAS is already mounted.

2Two Detection Methods

GoMount offers two independent ways to detect whether you are on a trusted network. You can use either one, or both at the same time.

IP Range Detection

GoMount monitors your Mac's assigned IP address. When it falls within a subnet you define, GoMount triggers the mount. This method works on both Wi-Fi and Ethernet connections and is ideal for fixed home or office networks where your router assigns addresses in a predictable range.

• Works with any network interface (Wi-Fi, Ethernet, Thunderbolt bridge)
• Ideal for static or semi-static IP assignments
• Not affected by Wi-Fi network renaming

Wi-Fi SSID Matching

GoMount reads the name (SSID) of the Wi-Fi network your Mac is currently connected to. When the SSID matches one on your trusted list, the mount triggers. This method is simpler to set up and perfect for users who primarily connect via Wi-Fi.

• Setup takes seconds — just type your Wi-Fi name
• Works even if your IP address changes frequently
• Does not trigger on Ethernet or tethered connections

3Setting Up IP Range Rules

Open GoMount Settings and switch to the Rules tab. Under IP Range, enter your home network's subnet in CIDR notation.

Common examples:

• 192.168.1.0/24 — Covers all addresses from 192.168.1.1 to 192.168.1.254
• 10.0.0.0/8 — Covers the entire 10.x.x.x private range
• 172.16.0.0/12 — Covers the 172.16.x.x through 172.31.x.x range

GoMount evaluates the rule every few seconds. As soon as your Mac receives an IP inside the configured range, it begins the mount sequence. When your IP leaves the range, GoMount safely unmounts the volume to prevent data corruption.

4Setting Up Wi-Fi SSID Rules

In the same Rules tab, find the Wi-Fi SSID field. Type the exact name of your home Wi-Fi network. SSID matching is case-sensitive and must match character for character.

Examples:

• MyHome_5G
• FamilyWiFi
• NETGEAR48

GoMount uses macOS's built-in CoreWLAN framework to read the current SSID. It does not scan nearby networks or store your Wi-Fi password. The SSID check happens locally on your Mac and never leaves the device.

5Combining Rules with OR Logic

When you configure both an IP range and a Wi-Fi SSID, GoMount treats them as an OR condition. The NAS mounts when either rule is satisfied. This gives you flexibility for complex setups.

Here is how the logic works:

• IP matches, SSID does not match → Mount triggers (e.g., Ethernet connection)
• SSID matches, IP does not match → Mount triggers (e.g., guest network with different subnet)
• Both match → Mount triggers immediately
• Neither matches → No mount; safe unmount if previously connected

6Real-World Scenarios

Scenario A: Single Home Network

You have one router, one Wi-Fi network, and your Mac connects wirelessly 99% of the time. Configure only the Wi-Fi SSID rule. It is the simplest setup and works perfectly.

Scenario B: Mixed Wi-Fi and Ethernet

You dock your MacBook at a desk with a Thunderbolt dock that provides wired Ethernet. When docked, you are on Ethernet; when undocked, you are on Wi-Fi. Configure both the IP range and the Wi-Fi SSID to cover both connection types.

Scenario C: Multiple Locations

You have a NAS at home and another at the office. Add two NAS devices in GoMount. For the home NAS, set your home IP range or SSID. For the office NAS, set the office IP range or SSID. Each NAS mounts only when you are at its corresponding location.

Scenario D: VPN Users

You connect to your home network via VPN while traveling. If your VPN assigns an IP in your home subnet, the IP range rule triggers and your NAS mounts remotely. If your VPN uses a different subnet, stick with the Wi-Fi SSID rule for local mounting only.

7Advanced Tips

Smaller Subnets for Precision

Instead of 192.168.1.0/24, you can use a smaller range like 192.168.1.0/26 to limit triggering to only the first 62 addresses. This is useful if you have a guest network on 192.168.1.128/26 and do not want guests to trigger your personal NAS mount.

Multiple SSIDs

If your router broadcasts multiple networks (e.g., MyHome_2.4G and MyHome_5G), you only need to add one. As long as both networks route to the same NAS, a single SSID or IP range rule covers them. If they are on isolated VLANs, configure the rule for the VLAN that can reach the NAS.

Monitoring the Menu Bar Icon

GoMount's menu bar icon uses four colors to show state:

• Green — NAS mounted and reachable
• Blue — Attempting to mount
• Yellow — Network conditions met, but mount in progress or retrying
• Gray — Outside trusted network, safely unmounted

Connection Keep-Alive

In the NAS settings, enable Keep-Alive to prevent macOS from dropping idle connections. This is especially important for SMB shares, which macOS tends to disconnect after periods of inactivity. Keep-alive sends periodic packets to maintain the mount.

8Troubleshooting

NAS does not mount when I come home

• Verify the IP range or SSID is entered correctly.
• Check that the NAS itself is powered on and reachable (try pinging it).
• Ensure your Mac's Wi-Fi or Ethernet is fully connected before GoMount evaluates the rule. There is a short delay after network association.
• Review the NAS credentials in Settings. A wrong password will cause repeated mount failures.

NAS mounts at the wrong time

• If using IP range, check whether public Wi-Fi or a neighbor's network uses the same subnet. Use a more specific range or switch to SSID matching.
• If using SSID, verify the network name is unique. Common default names like NETGEAR or Linksys can cause false positives.

Mount drops unexpectedly

• Enable Keep-Alive in NAS settings.
• Check your router's DHCP lease time. Short leases can cause IP changes that briefly break the connection.
• If on Wi-Fi, ensure your signal is strong. Weak signals can cause intermittent disconnections.

Rule changes do not take effect

• Changes to rules are applied immediately. If you do not see a change, toggle your network connection off and on to force a re-evaluation.
