I am using Caldera Open Linux Base which uses the 2.0.29 kernel and I have compiled the needed stuff into the kernel. I have a direct ethernet connection to my ISP. I am far from being a Linux guru and it would probably be a stretch to even call me a novice with linux but I do learn quick so bear with me. Ambrose Au's mini how to isn't quite specific enough for me to completely understand although I have accomplished what little I have by using it. Here's the problem:
1. If I type: ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0 and give a client machine the address 192.168.1.3 referring to 184.108.40.206 (linux box's true inet ip) then neither machine can see each other.
2. If I ifconfig eth0 to be 192.168.1.1 and change my client machine to refer to that address as its router then the machines see each other but neither can reach the internet.
3. I guess my question is how do I get eth0 to act as both 192.168.1.1 so that my internal net can see it and also act as 220.127.116.11 so that it can still reach the internet to forward the masq'ed traffic?
This may take a little interaction by e-mail if the responder wouldn't mind. Thanks
