Description
This specifies the connection type and the encapsulation method used for
your Static IP Address connection. The options available are Bridged IP
LLC, Bridged IP VC-Mux, Routed IP LLC, Routed IP VC-Mux or IPoA.
This is the permanent global IP address for your account. This is the
address that is visible outside your private network. Get this from your ISP.
This is the Subnet mask for the WAN interface. Get this from your ISP.
This is the IP address of your ISP's Gateway router. It provides the
connection to the Router for IP routed traffic that is outside your ISP's
network. That is, this will be the primary connection from the Router to most
of the Internet. Get this IP address from your ISP.
This is not required for all IPoA connections. Check with your ISP for an
ARP server IP address if this is necessary for your IPoA connection.
This is the IP address of the first choice for Domain Name Service (DNS)
used to match the named URL web address used by most browsers with
the actual global IP address used for a web server. Usually this will be a
server owned by the ISP. Get this IP address from your ISP.
This is the second choice for a DNS server. Get this IP address from your
ISP.
The Maximum Transmission Unit size may be changed if you want to
optimize efficiency for uploading data through the WAN interface. The
default setting (1400 bytes) should be suitable for most users. Some user
may want to adjust the setting to optimize performance for wireless traffic or
when low latency is desired (such as with Internet gaming). It is highly
recommended that the user research how adjusting the MTU may affect
network traffic for better or worse.
Network Address Translation may be enabled or disabled with the pull-
down menu. Keep in mind that disabling NAT allows on a single computer
to be used for Internet access through the Router. NAT is enabled and
disabled for the Router on all connections (i.e. Pvc0 – Pvc7) if your Router
is set up for multiple virtual connections.
Use this to universally enable or disable the Firewall and Filter features
available in the Router. If you disable this you will not be able to configure
settings in the Firewall Configuration window or the Filters window in the
Advanced directory.
