Configuring a VPN on the HP TMS zl Module
L2TP over IPsec VPNs
7. Under Tunnel Configuration, for Server IP Address, type the IP address and
subnet prefix length of the TMS zl Module in its capacity as L2TP Network
Server (LNS). For example, type 172.16.80.1.
This is a virtual IP address in an unused subnet (the subnet must not be
configured as a TMS VLAN or a VLAN on the host switch). The subnet will
be automatically placed in the External zone. Use the same server IP
address for each user’s account.
8. For User IP Address, type the IP address that the remote client uses on the
tunnel. This IP address must be on the same subnet as the server address
that you configured in the previous step.
Although you will place multiple remote clients in the same subnet, make
sure to assign each user account a unique IP address.
9. Configure settings in the Optional section if you want L2TP clients to use
your network’s DNS or WINS servers on the VPN connection:
a. For Primary DNS Server, type the IP address of a DNS server that the
remote client can use to resolve hostnames.
b. For Secondary DNS Server, type the IP address of another DNS server.
c. For Primary WINS Server, type the IP address of a WINS server.
d. For Secondary WINS Server, type the IP address of another WINS
server.
