Setting Up Your Ip Address - Multitech ProxyServer MTPSR3-200 User Manual

ProxyServer User Guide
Setting up your IP Addresses
Considerations for setting up your IP addresses; the LAN address is a static address that is unique to
your LAN, the WAN addresses can be static address which you have to enter or dynamic address
that are assigned by your ISP.
When the IP setup dialog box is displayed and the LAN is highlighted, the ISP Assigns Dynamic
Address option is greyed out (not active). The IP Address and Net Mask fields are active. This
requires you to enter you unique LAN IP address and net mask for your LAN.
Now consider the WAN ports, are they going to be assigned dynamically by your ISP or are you
going to have to enter WAN IP addresses and net masks for each WAN port. The majority of the time
the WAN addresses are going to dynamically asssigned by your ISP. If the addresses are being
assigned dynamically by your ISP when the port is activated, you do not have to do anything for the
WAN ports in this dialog box.
If the WAN port IP addresses are static addresses in which you own the IP addresses, you have to
click on ISP Assigns Dynamic address option which disables the option and assign IP addresses for
your WAN ports. If you are using Point-to-Point Protocol (PPP) or Serial Line IP Protocol ((SLIP), the
WAN port IP address have to be unique for each port. If you are using MultiLink PPP (MLPPP), only
one IP address is required for all three WAN ports.
The Client side Internet Parameters Gateway Address field is used if a second router is connecting
two LANs together. Then the Gateway Address of the router on your LAN would be entered in this
field.
An IP address is a combination of a network number and a host number or ID. IP address masks are
used to specify the network or subnet portion of the IP address. IP addresses and masks are 32-bit
values. These are usually provided in what is known as the dotted decimal notation. In this notation,
each 8-bit portion of the address is given a decimal quantity separated by a dot. For example,
192.2.10.1. The Proxy Server expects all IP addresses to be provided in dotted decimal notation.
Among IP addresses, address 0.0.0.0 and 127.?.?.? cannot be specified as they are special case
addresses not used on the internetwork for addressing. For Class A, B, and C addresses, you will
usually specify address masks of 255.0.0.0, 255.255.0.0 and 255.255.255.0 respectively unless other
subnets have been set up.
The net mask specifies the network or subnet portion of an IP address. The net mask is a 32-bit
value presented in a dotted decimal notation.
