branch office 2
Create your Asymmetric Digital Subscriber Line (ADSL) connection. Asynchronous Transfer
Mode (ATM) is always used over ADSL.
enable adsl=0
create atm=0 over=adsl0
add atm=0 channel=1
Branch 2 uses PPPoEoA (PPP over virtual ethernet over ATM). Create the virtual ethernet
over ATM.
create eth=0 over=atm0.1
Create your PPPoE link, and define the username and password needed for Internet access.
This is provided by your Internet Service Provider (ISP). Use iprequest=on so that the
interface obtains its address dynamically from the ISP—this office has no incoming roaming
VPN clients so does not need a fixed address.
create ppp=0 over=eth0-any echo=10 lqr=off bap=off idle=off
set ppp=0 iprequest=on username="branch office 2" password=branch2
Enable IP
enable ip
Define the vlan
1
interface address. This VLAN connects the router to the branch office LAN.
add ip int=vlan1 ip=192.168.142.254
The interface ppp0 (over virtual ethernet and ATM/ADSL) provides the Internet connection
interface. Enable IP remote assignment, to allow your ISP to dynamically assign an IP address
to ppp0.
enable ip remote
Configure a temporary null address.
add ip int=ppp0 ip=0.0.0.0
Add a default route out the ADSL PPP interface. When using PPP, it is valid to define a null
value next hop.
add ip rou=0.0.0.0 mask=0.0.0.0 int=ppp0 next=0.0.0.0
