3.3.4 Configuring the Basics: Step 4 - Configuring the Routing

Table

i) Adding a Default route through a Gateway

(No default route is required for PPPoA and PPPoE line protocols.)

Assuming the WAN Gateway given by your ADSL Service Provider is 202.166.29.2:

ip route add default 0.0.0.0

202.166.29.2

0:0:0:0

ii) Dynamic Routing

If dynamic routing is not required, it is recommended to disable this feature

to reduce unnecessary traffic:

ip rip accept all none

ip rip send all none

3.3.5 Configuring the Basics: Step 5 - Enabling IP Forwarding

To enable IP forwarding between your LAN and WAN,

ip relay all

3.3.6 Configuring the Basics: Step 6 - Enabling NAT

To enable NAT on a WAN interface,

i) For RFC 2684 (RFC 1483) Ethernet Framing/1483 IP Framing/1577 IPoA

Assuming the WAN interface name is wan:

ip nat add

wan

ii) For RFC 2364 PPPoA / RFC 2516 PPPoE

ip nat add ppp_device

You may proceed to section 3.4 to set up your NAT Inbound Port Forwarding.

3.3.7 Configuring the Basics: Step 7 - Saving the Configurations
