> **Possible workaround**: Configure the VPN to bridge networks instead of routing to enable ARP, though this depends on the VPN setup and security requirements.
# Other Workarounds
## Other Workarounds
The following workarounds should work for most complex network setups.
## Supplementing Plugins
### Supplementing Plugins
You can use supplementary plugins that employ alternate methods. Protocols used by the `SNMPDSC` or `DHCPLSS` plugins are widely supported on different routers and can be effective as workarounds. Check the [plugins list](./PLUGINS.md) to find a plugin that works with your router and network setup.
## Multiple NetAlertX Instances
### Multiple NetAlertX Instances
If you have servers in different networks, you can set up separate NetAlertX instances on those subnets and synchronize the results into one instance using the [`SYNC` plugin](https://github.com/netalertx/NetAlertX/tree/main/front/plugins/sync).
## Manual Entry
### Manual Entry
If you don't need to discover new devices and only need to report on their status (`online`, `offline`, `down`), you can manually enter devices and check their status using the [`ICMP` plugin](https://github.com/netalertx/NetAlertX/blob/main/front/plugins/icmp_scan/), which uses the `ping` command internally.

To create truly dummy devices, you can use a loopback IP address (e.g., `0.0.0.0` or `127.0.0.1`) or the `Force Status` field so they appear online.
## NMAP and Fake MAC Addresses
### NMAP and Fake MAC Addresses
Scanning remote networks with NMAP is possible (via the `NMAPDEV` plugin), but since it cannot retrieve the MAC address, you need to enable the `NMAPDEV_FAKE_MAC` setting. This will generate a fake MAC address based on the IP address, allowing you to track devices. However, this can lead to inconsistencies, especially if the IP address changes or a previously logged device is rediscovered. If this setting is disabled, only the IP address will be discovered, and devices with missing MAC addresses will be skipped.
