Virtual Private Networks
IPsec VPNs
Note Typically, the local addresses are internal addresses on your private
network while the local gateway address (which you configured in
the IKE policy) is the TMS zl Module’s public or external address. If,
however, for whatever reason the set of local addresses specified here
includes the local gateway address, you must create a Bypass policy
to exclude IKE traffic to and from the module from the VPN. Other-
wise the VPN cannot be established. See “Configure Bypass and
Ignore IPsec Policies” on page 7-84.
c. Local Port is present if you selected TCP or UDP for Protocol. Type a
specific port for the service to which remote clients are allowed
access or leave the field blank (which allows traffic to any port).
d. For Remote Address, specify the addresses for all remote endpoints
allowed to send and receive traffic over the VPN.
Do one of the following to specify remote addresses:
– Select Any to permit any IP address.
– Select a single-entry IP, range, or network address object.
– Manually type an IP address, an IP address range, or a network
address in CIDR format.
e. Remote Port is present if you selected TCP or UDP for Service. Type the
port number for the service that you want to allow local endpoints to
access in the remote network. Or leave the field blank (which allows
traffic to any port).
f. If you selected ICMP for the protocol, for ICMP Type, select Any.
If you select Echo or Timestamp, the tunnel must use manual keying
instead of IKE. See “Create an IPsec Policy That Uses Manual Keying”
on page 7-64.
9. For Proposal, select a previously-configured IPsec proposal.
The IPsec proposal specifies the IPsec mode, IPsec protocol, and the
authentication and encryption algorithms that secure the VPN connec-
tion. See “Create an IPsec Proposal” on page 7-53.
