Virtual Private Networks
Configure an IPsec Site-to-Site VPN with Manual Keying
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 that you
specify here includes the local gateway address, you must create a
Bypass policy to exclude IKE traffic to and from the module from the
VPN. Otherwise the VPN cannot be established.
See “Configure Bypass and Deny IPsec Policies” on page 7-354.
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 IP addresses of all remote endpoints
allowed to send and receive traffic over the VPN (indicated by 4 in
the figure).
Do one of the following to specify addresses:
– Select Any to permit any IP address.
– Select the single-entry IP, range, or network address object that
you configured for remote endpoints.
– Manually type an IP address, IP address range, or network
address in CIDR format.
e. Remote Port is present if you selected TCP or UDP for Protocol. 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, Echo,
or Timestamp.
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 7-125.
