Adsl - Secure Computing SG300 User Manual

For aliases on interfaces that have the DMZ or Internet firewall class, you must also
setup appropriate Packet Filtering and/or Port forwarding rules to allow traffic on these
ports to be passed onto the local network. See the chapter entitled Firewall for details.
IPv6
You must enable IPv6 under the Network Settings Connection tab for each connection
that supports IPv6. In particular, enable IPvg for the LAN connections on which you wish
to advertise routes and on the Internet connections on which you wish to create 6to4
tunnels.
When IPv6 is enabled, the following actions are performed
o Site-local addresses are assigned to LAN connections
o The site-local DNS server address (fec0:0:0:ffff::1/64) is assigned to LAN
connections if the DNS proxy is enabled.
o Router advertisements are sent on LAN connections.
o 6to4 tunnels are created on Internet connections.
o A default set of IPv6 packet filter rules are enabled. These rules are stateless (as
opposed to the IPv4 packet filter rules which are stateful). The default rules only
support a singe LAN connection and a single WAN connection. You can
customize these rules on the Custom IPv6 Firewall Rules page.
You may enter a site level aggregation value for this connection in Site Level
Aggregation. It is used in the creation of a site local address and for routing IPv6 traffic
on this connection. This setting is only available for LAN connections, and should be
unique.

ADSL

To connect to the Internet using DSL, select ADSL from the Change Type pull-down
menu for the interface that connects to your DSL modem. ADSL connections have the
interface firewall class of Internet.
If you have not already done so, connect the appropriate network port of your SnapGear
unit to your DSL modem. Power on the DSL modem and give it some time to initialize. If
fitted, ensure the Ethernet link LEDs are illuminated on both the SnapGear unit and DSL
modem.
