Ros Soft Routing: DHCP Server configuration and PPPoE client configuration

Let's do a simple experiment on Ros today, in a typical dozens of-person small company or a few people's home, if you come to how Ros do the most basic internet operation.

Knowledge Points:

1. Ros as a DHCP Server for the intranet.

2. Ros as the client of PPPoE (the average person rarely uses ADSL access)

3. Ros makes a pat so that intranet users can surf the Internet.

The topology diagram is as follows:

In the topology diagram above, a Cisco emulator was used to simulate PPPoE servers, and Ros and WinXP were installed in the VMware Workstation virtual machines. The reader will be able to complete this experiment with only a single computer.

PPPoE Server configuration:

On the principle of PPPoE and can see the author of another blog post http://senyang.blog.51cto.com/3427514/1680155

For the convenience of the reader, the following configuration is directly copied and pasted into the Cisco emulator.

Basic ROS Configuration:

IP address Add address=192.168.1.1/24 interface=ether3

ROS DHCP Server configuration:

[Email protected]] IP dhcp-server> setupselect interface to run DHCP server ONDHCP server Interface:ether3select network for DHCP address  ESDHCP address Space:192.168.1.0/24select Gateway for given networkgateway for DHCP network:192.168.1.1select pool of IP Addresses given out by the DHCP serveraddresses to give Out:192.168.1.2-192.168.2.254select DNS Serversdns servers:192.168. 1.1Select lease Timelease Time:3d[[email protected]] IP dhcp-server>

Viewed on WinXP, the IP address has been obtained.

Configure Ros for the client of PPPoE:

Interface pppoe-client Add Interface=ether3 user=user1 password=cisco add-default-=route=yes use-peer-dns=yes disable= No

View IP Address:

To configure NAT:

Before NAT is configured, WinXP cannot ping the 1.1.1.1 on the public network, after the configuration, you can ping pass, the experiment was successful.

The keyword "Masquerade" Here is Pat, which translates multiple IP addresses into an IP address.

More about the configuration of Ros, I will slowly introduce, I will work with you to learn this fine classic soft route.
