It seems to be quite hard to find an 8 port hub with a coax connector,
though I will keep looking.
In the meantime can you expand on what I need to do following your (i)
seperate subnets suggestion.
I am already running ...
1) DHCP(providing IP addresses to the local machines and also updating the
DNS zone files automatically)
2) DNS (administering the local domain and forwarding to my Cable Company's
3) SuSEFirewall2 (blocks everything inbound, there are NO services
accessible from the internet other than those initiated by the local network
4) Samba to support Windows Clients
so I think I have all the parts running I need, but need some pointers on
how to add the extra interface into the settings for each.
Thanks everyone for your advice.
