Complicated internet sharing question

[merf07]

I have kind of a home network pickle regarding some very fixed hardware. Hopefully somebody here may be able to help me.

I need Computer1(wireless ethernet card, 56K card) to feed a connection to Computer3 (56K card). Is it possible I can get Computer3 to connect to the internet through Computer1 via the two 56k modems?

If so, what software/configuration is required?
Thank you in advance to anyone with advice.

Don't do it that wat, Get a Router or Switch and network them all.

That's the thing though, the 56k computer can't tap into the ethernet. Can it do it through the other computer?

How would the one that has the connection to the internet accept a call still from the other computer? No you can't do it that way. They could use seperate phone lines to get connections, but you can't share a connection through a modem. Why can't the other computer tap the network?
