EoIP Application Example
Description
Let us assume we want to bridge two networks: 'Office LAN' and 'Remote LAN'. The networks are
connected to an IP network through the routers [Our_GW] and [Remote]. The IP network can be a
private intranet or the Internet. Both routers can communicate with each other through the IP network.
Example
Our goal is to create a secure channel between the routers and bridge both networks through it. The
network setup diagram is as follows:
[Our_GW]
192.168.1.1 [Remote]
192.168.2.1
IP Network
Remote
LAN
Office

PPTP Tunnel
Figure 20: EoIP Application Example
To make a secure Ethernet bridge between two routers you should:
Create a PPTP tunnel between them. Our_GW will be the pptp server:
[admin@Our_GW] interface pptp-server> /ppp secret add name=joe service=pptp \
\... password=top_s3 local-address=10.0.0.1 remote-address=10.0.0.2
[admin@Our_GW] interface pptp-server> add name=from_remote user=joe
[admin@Our_GW] interface pptp-server> server set enable=yes
[admin@Our_GW] interface pptp-server> print
Flags: X - disabled, D - dynamic, R - running
# NAME USER MTU CLIENT-ADDRESS UPTIME ENC...
0 from_remote joe
[admin@Our_GW] interface pptp-server>
The Remote router will be the pptp client:
[admin@Remote] interface pptp-client> add name=pptp user=joe \
\... connect-to=192.168.1.1 password=top_s3 mtu=1500 mru=1500
[admin@Remote] interface pptp-client> enable pptp
[admin@Remote] interface pptp-client> print
Flags: X - disabled, R - running
0 R name="pptp" mtu=1500 mru=1500 connect-to=192.168.1.1 user="joe"
password="top_s2" profile=default add-default-route=no
[admin@Remote] interface pptp-client> monitor pptp
status: "connected"
uptime: 39m46s
encoding: "none"
[admin@Remote] interface pptp-client>
See the PPTP Interface Manual for more details on setting up encrypted channels.
