One day my computer was without available ISA slots. I installed FreeBSD but the damned Winmodem doesn't work, so I had a idea to resurrect the other pentium 100 computer to use its free slots to install an old 14kbps modem. FreeBSD was also loaded in this computer as a gateway to the other computer without modem and the internet by ip aliasing (ppp -alias). Since the gateway computer doesn't have better space (170mb) and power to install some other programs, I would like to use it only for a gateway. This is the small LAN : ------------------ ---------------------- | ether.nostromo | serial | ppprouter.nostromo | 14kbps ------------ | 192.168.1.2 |---------| 192.168.1.1 |---------| Internet | ------------------ cable ---------------------- modem ------------ P2 450Mhz Old Pentium 100 Mhz FreeBSD 3.2 FreeBSD 3.1 (ppp nullmodem) (ppp -alias isp) (ppp nullmodem) natd [options] My problems appeared when I tried to access the client computer from internet through the gateway. Such connection always finished on the gateway computer. Finally, what I want to know is how can I get all the gateway ports from telnetd, ftpd, httpd etc. redirected to the respective client ports. Basically, is something like to make the gateway computer ports invisible to the outside computers, so any connection addressed to its IP will finish into the client computer (ether.nostromo). Is this possible ? How ? Thank you for the attention. P.S.: I've used "natd -port_redirect 192.168.1.1:ftp ftp" and nothing has changed. I tried some other options, but I am not sure what is the best one. Is there any known natd guide on the internet for FreeBSD ?
