Reference Manual for the ProSafe VPN Firewall 25 with 4 Gigabit LAN and Dual WAN Ports

Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the dynamic DNS service will not work because private addresses will not be routed on the Internet.

Step 6: Configure the WAN Options (If Needed)

Perform the following steps to configure the WAN options:

1.If you haven’t already, log in to the firewall at its default LAN address of http://192.168.1.1 with its default user name of admin, default password of password, or using whatever password and LAN address you have chosen for the firewall.

2.From the Main Menu of the browser interface, under WAN Setup, click on Options. You will get the WAN1 screen shown in Figure 4-10and can get the WAN2 screen from there using the pulldown.

3.Edit the default information you want to change.

MTU Size—The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or 1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.
