LAN IP Setup Help
The default values are suitable for most users and situations.
Enable print server
If enabled, the printer port provides shared printing services (network printer) via the parallel port. (Client PCs must use the provided print port software in order to print.)
If disabled, the printer port is unavailable to all users.
LAN TCP/IP Setup
These are advanced settings that you may configure if you are a network administrator. RIP is applicable if your network contains multiple routers.
- IP Address: Type the IP address of your router (factory default: 192.168.0.1).
- IP Subnet Mask: The subnet mask specifies the network number portion of an IP address. Your router will automatically calculate the subnet mask based on the IP address that you assign. Unless you are implementing subnetting, use 255.255.255.0 as the subnet mask (computed by the router).
- RIP Direction: RIP (Routing Information Protocol, RFC1058 and RFC1389) allows a router to exchange routing information with other routers. The RIP Direction selection controls how the router sends and receives RIP packets. Both is the default.
- When set to Both or Out Only, the router will broadcast its routing table periodically.
- When set to Both or In Only, it will incorporate the RIP information that it receives.
- When set to None, it will not send any RIP packets and will ignore any RIP packets received.
- RIP Version: This controls the format and the broadcasting method of the RIP packets that the router sends. (It recognizes both formats when receiving.) By default, this is set for RIP-1.
- Disabled will disable the RIP feature completely.
- RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you have an unusual network setup.
- RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format.
- RIP-2B uses subnet broadcasting.
- RIP-2M uses multicasting. (See note below.)
Note: Multicasting can reduce the load on non-router machines because they do not listen to the RIP multicast address and will not receive the RIP packets. However, if one router uses multicasting, then all routers on your network must use multicasting.
MTU Size
The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you may need to reduce the MTU. This is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.
Use router as DHCP server
By default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server, providing TCP/IP configuration for all computers connected to the router's LAN.
If another device on your network will be the DHCP server, or if you will manually configure all devices, clear the Use router as DHCP server check box. Otherwise, leave it checked.
- Starting IP Address: This box specifies the first of the contiguous addresses in the IP address pool.
192.168.0.2 is the default start address.
- Ending IP Address: This box specifies the last of the contiguous addresses in the IP address pool.
192.168.0.51 is the default ending address.
Reserved IP Table
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the same IP address each time it access the DHCP
server. Reserved IP addresses should be assigned to servers that require permanent IP settings.
To reserve an IP address:
- Click the Add button.
- In the IP Address box, type the IP address to assign to the PC or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.0.X)
- Type the MAC Address of the PC or server.
(Tip: If the PC is already present on your network, you can copy its MAC address from
the Attached Devices menu and paste it here.)
- Click Apply to enter the reserved address into the table.
Note: The reserved address will not be assigned until the next time the PC contacts the
router's DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.
To edit or delete a reserved address entry:
- Click the button next to the reserved address you want to edit or delete.
- Click Edit or Delete.
