15.4  Configuring remote access client via PPPoE
PPPoE is a tunneling protocol that allows encapsulating IP PPP over Ethernet connections and has PPP 
connection software capabilities, which allows using it to establish virtual connections to a neighboring 
Ethernet device or a point-to-point connection that is used to transmit IP packets, and also works with PPP 
features. This allows applying conventional PPP-oriented software to configure the connection that uses not 
serial communication link but packet-oriented network (for example, Ethernet) to organize a classical 
connection with login and password for Internet connections. In addition, IP address on the opposite side of 
connection is assigned only when PPPoE connection is open, allowing the dynamic reuse of IP addresses.
15.4.1  Configuration algorithm
Step Description Command Keys
1 Create a PPPoE tunnel and switch to its 
configuration mode.
esr(config)# tunnel pppoe 
<PPPoE>
<PPPoE> – tunnel sequence number 
from 1 to 10.
2 Specify the description of the 
configured client (optional).
esr(config-pppoe)# 
description <DESCRIPTION>
<DESCRIPTION> – PPPoE server 
description, set by the string of up to 
255 characters.
In addition to creating OpenVPN server, open TCP port 1194 in the firewall.
