3. Click Apply to save your settings. VPN tunnel clients are now able to connect to the UTM
and receive a virtual IP address in the client address range.
Add Routes for VPN Tunnel Clients
The VPN tunnel clients assume that the following networks are located across the
VPN-over-SSL tunnel:
• The subnet that contains the client IP address (that is, PPP interface), as determined by
the class of the address (Class A, B, or C).
• Subnets that are specified in the Configured Client Routes table on the SSL VPN Client
screen.
If the assigned client IP address range is in a different subnet from the local network, or if the
local network has multiple subnets, or if you select split-mode tunnel operation, you need to
define client routes.
To add an SSL VPN tunnel client route:
1. Select VPN > SSL VPN > SSL VPN Client. The SSL VPN Client screen displays (see
Figure 219 on page 366).
2. In the Add Routes for VPN Tunnel Clients section of the screen, specify information in the
following fields:
• Destination Network. The destination network IP address of a local network or
subnet. For example, enter 192.168.1.60.
• Subnet Mask. The address of the appropriate subnet mask.
3. Click the Add table button. The new client route is added to the Configured Client Routes
table.
If VPN tunnel clients are already connected, restart the UTM. Restarting forces clients to
reconnect and receive new addresses and routes.
Primary DNS Server The IP address of the primary DNS server that is assigned to the VPN tunnel
clients. This setting is optional.
Note: If you do not assign a DNS server, the DNS settings remain
unchanged in the VPN client after a VPN tunnel has been established.
Secondary DNS Server The IP address of the secondary DNS server that is assigned to the VPN
tunnel clients. This setting is optional.
Client Address Range Begin The first IP address of the IP address range that you want to assign to the
VPN tunnel clients.
Client Address Range End The last IP address of the IP address range that you want to assign to the
VPN tunnel clients.
