IP Passthrough Configuration Example
In this example, the 6351 router shares its public IP address with another device.
NAPT is configured to support public FTP and web servers connected directly to
the router’s LAN interface. These servers share the same public IP address as the
passthrough device and are accessible to remote users via the confi gured static
NAPT mappings.
The commands and syntax for this example are:
ip routing enable
bridging disable
proxy arp eth1 enable
ifn address eth1 192.168.158.1 255.255.255.0
pppoe enable
ppp ip passthrough
nat napt enable
nat napt map tcp 192.168.158.11 80
nat napt map tcp 192.168.158.10 21
