132 Chapters Configuring branch office tunnels

Click the Filters drop-down list and choose the filter that you want this

branch office connection to use. The default is permit all. You can specify

one filter. Packet filtering controls the types of access allowed for users of this

branch connection. Filters are based on various parameters, including protocol
ID, direction, IP addresses, source, port, and TCP connection establishment.
Filters are defined on the Profiles > Filters window.

For Authentication, configure the authentication that is used between the
local and remote branch office. The fields that appear in this window depend

on whether you are using an IPsec, PPTP, or L2TP tunnel type.

Set up the authentication method for the connection, for example, text
pre-shared key. Enter the key (for example, bostoncleveland), then retype it in
the Confirm Text String field.

If you create a branch office connection using any IPsec certificate and you
choose IP address as the alternate name, you must use the IP address of the

public interface that is on the branch office end of the connection.

Select to reset the Tunnel MTU. When you change the MTU value, you must

reboot the Nortel VPN for the new value to take effect.

Enter an MTU Value. Enter a value from 576 through 1788 bytes. The default

value is 1788.

10 Under NAT, select either PortNAT or none. NAT enables you to build your

VPN without requiring that you reconfigure or rename your existing network.

NAT sets are defined on the Profiles > NAT window. For further information
on NAT, see Nortel VPN Router Security — Firewalls, Filters, NAT, and QoS.

For IP Configuration, select either Static or Dynamic routing for this branch

office connection:

•

If you choose Static routing, you must manually specify the Accessible
Networks (the private internal networks behind a VPN Router that are

accessed via the branch office connection).

•

If you choose Dynamic, the routing protocol automatically determines

the accessible networks based on information that is entered on the

System > LAN Interfaces > Edit IP Address window. When this

Dynamic is selected additional settings for OSPF and RIP appears.

12 Click Create Local Network to go the Profiles > Networks window and

define a local network. The Local networks are the subnetworks on the private

internal network of the local VPN Router.If you want to edit an existing local
