Niti v sanjah !
Uporabi hub, ki je danes ranga 10k SIT, se boljse pa bo, ce si bos privoscil se
eno karto z BNC, ki je ranga 2k SIT. Premisli, v kolikor bos kabelski modem vezal
na hub, kako on dela z prometom, ali je viden navzven ali ne, da ne bo potem ves
promet viden navzven. Nisem sicer cisto 100 %, kako recimo BayNetworks modemi
delajo, vseeno pa ni prevec pametno imeti cable modema na "istem" dratu.

Routing, masquarading in kaksen proxy naceloma ni problem urediti, zato je v
tvojem primeru uporaba se ene ethernet kartice najboljsa resitev...

Potem izgledajo device recimo takole:
