In the LANCOM, the XAUTH protocol uses entries in the PPP table for remote site authentication. Use of the entries in the PPP table is dependent on which direction the connection is established, i.e. on the XAUTH operating mode:
| XAUTH operating mode | Server | Client |
|---|---|---|
| XAUTH user name | Remote site from the PPP table. The PPP-table entry is selected for which the PPP remote site corresponds to the transferred XAUTH user name. The PPP remote site must also match the VPN remote site used. | User name from the PPP table. The entry selected from the PPP table is that for which the PPP remote site corresponds to the VPN remote site used. |
| XAUTH password | Password from the PPP table. | Password from the PPP table. |
Note: In LCOS version 7.60 in XAUTH operating mode, the XAUTH user
name has to agree with the name of the VPN remote site. For this reason
only one user can be authenticated by XAUTH for each VPN remote site.
Authentication by RADIUS server is not available with LCOS 7.60.
