Firewall; Nat; Vpn Client Termination - Nortel 252 Fundamentals

34 Chapter 5 User Notes
5 Clicking Sound
The Business Secure Router will click once every two minutes until an ADSL line
is connected.

Firewall

1
Address Range Validation
In the firewall rules, the router does not confirm when given an address range, that
the second address is higher than the first. If this type of address range is entered,
the range is ignored.
2
Automatic Firewall Programming
Configurations to various areas of the router, such as remote management or
adding a SUA Server, do not automatically add the appropriate rules to the
Firewall, to enable the traffic to pass through the router. These need to be added
separately.
Note: Firewall rules do not apply to IPSec tunnels.

NAT

1
Deleting NAT Rule Does Not Drop an Existing Connection
If a NAT rule is deleted, the router must be rebooted to apply the change to
existing service connections. This is already noted in the GUI.
2 NAT Traversal Status
If NAT Traversal is enabled, but is not needed (because the client is not behind a
NAT router), it will be shown as 'inactive' in the VPN Client Monitor. This may
confuse some users.
