Hangup at
Some providers disconnect an ADSL dial-up link automatically after it has been online
for 24 hours without interruption. During working hours this might be bothering. You can
enter a time at which SX-GATE will always hangup so disconnection can take place
e.g. at night-time.
Leave the input field empty if a scheduled hangup is not required.

IP addresses
IPv4 address
You can either accept a dynamic IP assigned by the peer or specify an IP address.
DS-Lite Address-Family-Transition-Router (AFTR)
In dual stack light Internet links IPv4 packets are tunneled via IPv6. The tunnel endpoint
on the provider side is a special router. It its address isn't advertised with DHCP you
can enter the address here.
IPv6 address
Enter an IPv6 address for this interface.
Prefix length
The IPv6 prefix length is the equivalent to IPv4 netmasks. The typical prefix length ist
64, but your provider might have told you a higher value.
IPv6 privacy extension (RFC3041)
A dynamic IPv6 address derived with SLAAC is based on the hardware address of the
network card. So it can be tracked worldwide easily. Enable this option and SX-GATE
will add a temporary random address which is preferred.
IPv6 prefix delegation
Enable this option to ask your provider for an additional IPv6 network prefix, which is
then made available for internal networks by SX-GATE.
As soon as SX-GATE receives such a prefix, an entry is created in menu "Definitions >
IP objects" which will be named after the interface (e.g. "ipv6_prefix_adsl0" for "adsl0").
Subdivide the prefix by adding entries of type "IPv6 prefix" or "IPv6 address" and make
them refer to the prefix you received. You can use these objects in various configuration
options.
Additional IPv6 addresses (aliases)
You can specify additional IPv6 addresses for the select network interface.
