Enable PPTP server:
When a new configuration is applied, the router will listen to 120.11.5.1:1723. To view PPTP server session
status, use the following command:
esr# show remote-access status pptp server remote-workers
To view PPTP server session counters, use the following command:
esr# show remote-access counters pptp server remote-workers
To clear PPTP server session counters, use the following command:
esr# clear remote-access counters pptp server remote-workers
To end PPTP server session for user 'fedor', use one of the following commands:
esr# clear remote-access session pptp username fedor
esr# clear remote-access session pptp server remote-workers username fedor
To view PPTP server configuration, use the following command:
esr# show remote-access configuration pptp remote-workers
15.2 Configuring server for remote access to corporate network via L2TP protocol
L2TP (Layer 2 Tunneling Protocol) is a sophisticated tunneling protocol used to support virtual private
networks. L2TP encapsulates PPP frames into IP packets for transmission via global IP network, e.g. the
Internet. L2TP may be used for tunnel establishment between two local area networks. L2TP uses an
additional UDP connection for tunnel handling. L2TP protocol does not provide data encryption, therefore it is
usually combined with an IPsec protocol group that provides security on a packet level.
15.2.1 Configuration algorithm
Step Description Command Keys
1 Create L2TP server profile. esr(config)# remote-access l2tp
<NAME>
<NAME> – L2TP server profile
name, set by the string of up to
31 characters.
In addition to PPTP server creation, you should open TCP port 1723 designed for connection
handling and enable GRE protocol (47) for the tunnel traffic in the firewall.
