3G-GPRS-EDGE router IPL-G12
12 Configuring VPN connections between routers (3G-GPRS-EDGE)
12.1 Principles
A VPN is a safe link set between two end-points 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 2.
25 VPNs can be set on the WAN interface of the IPL-G12 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
company routers.
Once a type of VPN (TLS or IPSec) has been selected, all the VPN set
between the IPL-G12 router and another one must be the same.
Two steps are necessary to configure the IPL-G12 to create VPN
connections between routers :
1
st
step : Select and setup the VPN type parameters
Once a type of VPN has be selected, it applies to all the connections with remote routers.
2
nd
step : Create 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”.
