Siemens 5881 User Manual

If you will use the Point-to-Point Protocol (PPP) to establish the connection., you selected Using PPPoE. 
Perform the following steps to complete setting up the router.

1. Enter the User Name and Password, which are used for authentication when the PPP connection is being 

established.

2. In Service Name, enter the domain name of your network service provider. Use * as a default (for all 

services).

3. In PPPoE Timer, enter the number of seconds of inactivity that must elapse before the PPP connection 

closes. This helps to limit connection charges from your service provider during times of inactivity. The 
default entry of “permanent” will keep the PPP connection open constantly, with no time out interval.

4. Optionally select NAT Enabled to enable Network Address Translation (NAT). NAT allows multiple 

workstations on your LAN to share a single, public IP address. All outgoing traffic appears to originate from 
the router’s IP address.

5. Click Next. This displays the

If you will establish the connection based on IP addressing, you selected Not Using PPPoE. Perform the 
following steps to complete setting up the router.

1. IP Routing routes all IP packets for remote hosts to the WAN. Specify how to obtain an IP address and 

subnet mask by selecting one of the following:

Obtain configuration automatically from Wan using DHCP to have an IP address assigned 
automatically using DHCP.

Configure IP Routing manually to assign IP addresses manually. If you select this option, you must 
specify an IP Address, Subnet Mask, and Default Gateway in the appropriate fields. Default Gateway 
assigns the IP address of the next-hop device.

2. Optionally select NAT Enabled to enable Network Address Translation (NAT). NAT allows multiple 

workstations on your LAN to share a single, public IP address. All outgoing traffic appears to originate from 
the router’s IP address.
