# Can I use another port for the proxy server

<p class="callout info">**Note**: The license files for the proxy are in folder `/opt/flexlm/bin`. There are two license files: `atflexd-proxy.lic` and `proxy.lic`. Via these license files the license server process `lmgrd` starts two vendor daemons:</p>

1. **`atflexd`** for the T2K licenses
2. **`socbu`** for the 93k licenses

If the customer wants to use another port for the `lmgrd` process of the proxy server or another port for the `socbu` / `atflexd `vendor daemon, then the files in folder `/opt/flexlm/bin`

- `atflexd-proxy.lic`
- `proxy.lic`

need to be adapted with the appropriate port number on the SERVER line(s) for the lmgrd process and on the VENDOR line for the appropriate vendor daemon process on all used proxy license servers. So if the setup is an FNX triad, the port numbers need to be adapted on all three license servers.

Please always adapt both license files. The license server will run into errors, if you use for example different port numbers for the `lmgrd` process in file `proxy.lic` than in `atflexd-proxy.lic`.
