For example: ISP gave a public static IP block: example: 216.129.206.XXX/29 GATEWAY to the ISP router is: 216.138.192.XXX The external ADSL modem is connected to the ISP successfully with pppoe. How do I configure the public Interface eth0 on the Linux firewall? Do you have to use a WAN interface like pppoe on the Linux box? Could someone give me an example? Thanks in advance.
