NETGEAR FWG114P v2 How to Configure Dynamic DNS, Setting the MTU Size, Setting the WAN Port Speed

Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P v2

•Setting the MTU Size

The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes. For some ISPs, particularly those using PPPoE, you may need to reduce the MTU. This should not be done unless you are sure it is necessary for your ISP.

Any packets sent through the router that are larger than the configured MTU size will be repackaged into smaller packets to meet the MTU requirement. To change the MTU size, under MTU Size, enter a new size between 64 and 1500. Then, click Apply to save the new configuration.

•Setting the WAN Port Speed

In most cases, your router can automatically determine (AutoSense) the connection speed of the Internet (WAN) port. If you cannot establish an Internet connection and the Internet LED blinks continuously, you may need to manually select the port speed.

If you know that the Ethernet port on your broadband modem supports 100BaseT, select 100M; otherwise, select 10M.

How to Configure Dynamic DNS

If your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service, which will allow you to register your domain to their IP address, and will forward traffic directed to your domain to your frequently-changing IP address.

The router contains a client that can connect to a dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.

1.Log in to the router at its default LAN address of http://192.168.0.1, with its default user name of admin, default password of password, or using whatever password and LAN address you have chosen for the router.

2.From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS.
