What “local network access” means

Accessing a local network usually means reaching devices on your home or office LAN (for example: a router’s admin page, a NAS, a printer, or a smart TV) while your VPN connection is active.

A VPN typically creates an encrypted tunnel between your device and the VPN server. Traffic sent through that tunnel appears to originate from the VPN server rather than your local network. Because of that, local access may or may not work depending on whether your system sends “local” traffic through the tunnel, and how it decides what is considered local.

How it works in practice

Most of the time, your computer uses routing rules to decide where to send a packet:

  • Local (LAN) traffic is normally routed to your router over your local interface.
  • Non-local traffic is routed into the VPN tunnel.

When you connect a VPN, it installs new routes and often modifies DNS behavior. If the VPN (or your OS) routes your LAN subnet traffic into the tunnel, your LAN devices may no longer be reachable from your device—because the VPN server may not be connected to your local subnet.

If the VPN keeps LAN traffic on the local interface (or explicitly allows “local network access”), then requests to devices in your LAN continue to go to your router directly, and local access can work.

Split tunneling and “allow LAN” concepts

Two common ideas explain why local access sometimes works:

  1. Split tunneling (or traffic exceptions): Only some destinations are sent through the VPN tunnel, while other destinations (like your LAN subnets) stay local.
  2. Local network allowances: Some VPN clients provide an option to permit connections to local devices even while connected.

Exact wording and availability vary by VPN client and configuration, so treat these as general concepts rather than guaranteed features.

Key limitations and the main “gotcha”

The most common limitation is routing mismatch: the VPN connection changes what your device thinks is “local,” or it routes your LAN subnet traffic into the tunnel.

Other practical limitations include:

  • DNS changes: Even if you can reach local IP addresses, name-based access (e.g., nas.local) may fail if DNS is pointed to a resolver that can’t resolve local names.
  • Firewall rules: Host firewalls and router rules can block inbound or forwarded traffic, especially after a VPN reconnect.
  • Access across different networks: If the VPN server is not on your LAN (it usually isn’t), then “LAN traffic sent through the tunnel” will fail unless there is special network bridging or routing on both sides.

Importantly, some VPN providers or configurations may prefer to limit LAN reachability for safety or policy reasons. That means local access might be disabled by design even when it could theoretically be enabled.

Practical checks you can do

Use these checks to determine whether local network access should work on your setup:

  1. Test by IP, not by name Try reaching a LAN device using its local IP address (for example, 192.168.x.x). If IP works but names don’t, the issue is likely DNS-related.

  2. Verify your LAN subnet is truly local Confirm your device’s IP range (e.g., 192.168.1.0/24 vs. a different subnet) and check whether the VPN setup is configured to keep that subnet outside the tunnel (if such an option exists).

  3. Look for “local network” allowances in the VPN client In your VPN client’s settings, search for options related to allowing local network access, split tunneling, or bypassing the VPN for local/private ranges. If no such option exists, local access will depend on how the VPN config handles routes by default.

  4. Check firewall behavior after connecting Re-test right after connecting and again after reconnecting. If behavior changes, it can indicate that the VPN client modifies firewall rules or network profiles.

  5. Compare behavior with VPN off vs. on If local access works with the VPN disabled but not enabled, the VPN is almost certainly changing routing or name resolution in a way that blocks LAN reachability.

  • Routing vs. encryption: VPN encryption protects traffic, but it doesn’t automatically preserve local LAN routing. Encryption and routing are separate concerns.
  • “Private address ranges” aren’t automatically treated as local: Even if an address looks like a private IP range, the VPN or OS may still choose to send it into the tunnel.
  • LAN reachability can be directional: Some devices may be reachable from your laptop, but your laptop may not be reachable from LAN devices when the VPN is on, depending on firewall and network profile settings.

If you share (in general terms) what VPN client you use and whether your VPN is configured for split tunneling or “local network access,” it’s easier to narrow down which setting is most likely responsible. Without those details, the most reliable answer is: local network access while using a VPN is possible, but it depends on routing and whether LAN traffic is exempted or allowed from the tunnel.
