Juniper Firewall L2TP VPN configuration illustrated tutorial

The L2TP tunnel (L2TP tunnel) refers to the logical link between the second-tier Tunneling Protocol (L2TP) endpoints: LAC (L2TP access aggregator) and LNS (L2TP network server). When LNS is a server, LAC is the initiator of the tunnel and waits for the new tunnel. Once a tunnel is established, the new communication between this point will be two-way. In order to be useful to the network, high-level protocols such as Point-to-Point Protocol (PPP) are then passed through the L2TP tunnel.

Today, just learning the Juniper Firewall, just learned the configuration of L2TP VPN, so today we look at using Juniper Firewall to do L2TP VPN.

The first step: click: Objects>ip Pools we add an IP address pool, this address pool is mainly used to give us through the L2TP VPN dial-up users to allocate the IP address in the intranet.

As shown above: IP pool name is a name for our address pool so we can call it later.

Start IP: IP address at the beginning of our address pool

End IP: IP address of our address pool

Click OK when you are ready to enter.
