12 Creating VPN connections between routers
12.1 Principles
A VPN tunnel is a safe link set between two end-points routers over an IP network : Both routers
authenticate, data are encrypted and each device of a LAN can exchange data with each device f the
other one.
To get more explanations about how VPNs work, refer to appendix 1.
25 VPNs can be set on the WAN interface of the RAS-3G router.
Two types of VPN can be set : TLS VPN and IPSec VPN.
IPSec has the advantage to be a standard solution.
TLS is easier to employ because the transport layer is TCP or UDP; it is why, it can be easily used
when the VPN must pass through several or even numerous company routers.
Once a type of VPN (TLS or IPSec) has been selected, all the VPN set with the RAS-3G router will be
of the same type.
Two steps are necessary to configure the RAS-3G to create VPN connections between routers :
1
st
step : Select the VPN type and set up the VPN parameters
2 types of VPNs can be used to connect RAS-3G routers together or with other type of routers: IPSec
or TLS/ SSL
Once a type of VPN has be selected, it applies to all the connections with remote routers.
2
nd
step : Creating VPN connections
A connection can be an incoming connection
or an outgoing connection.
If a connection is an incoming connection,
the local router is named “VPN server” and
the remote router is a “VPN client”.
