I mention this, because I was thinking that I should search the solution into
masquarading, gateways, etc.
Is PC1 getting an IP address from your ISP?
How many leases have you purchased from your ISP?
Did you purchase the cable modem?
The reason for asking these questions:
1) The switches and hubs that I have seen will not do Network Address Translation [NAT]. However, Routers do.
2) If you only have 1 lease purchased from your ISP, why would you expect them to give you 2 addresses [assuming PC1 works]?
3) The cable modems that I have seen that are owned by the ISP [that is, you lease the cable modem] allow for exactly 1 network card MAC address. If PC1 works, then the cable modem may completely IGNORE other requests [which is what appears to be happening].
If you really do have a network switch or hub, then you have two options:
1) Purchase a CableModem/DSL Router (~$50-60 US), and let the switch collect dust, reset your cablemodem.
2) Purchase a 2nd Network Interface Card [NIC] (~$10-20 US) for either PC1 or PC2, connect the cablemodem to the machine that has 2 network cards [either card will do], connect the other card to your switch/hub, set up NAT, Install a Firewall, possibly reset your cablemodem.
Personally, I went with option 2, but then, it taught me a lot about networking, firewalls, etc. Option 1 is great for people who just want the thing to work. If you go with option 2, I would recommend putting the 2nd network card into PC2, since it is running Linux, and this is a Fedora List....
