Squid is a caching proxy for HTTP, not other protocols. Only HTTP clients (mainly web browsers) can use Squid, and only for things which can be wrapped as HTTP. (i.e. HTTP, HTTPS, FTP and Gopher). Squid happily coexists with proxies for other protocols if needed/desired. There is no conflict in running as many types of proxies you like on the same server. If all you are after is connection sharing then chances are that you don't actually need a proxy but maybe would be better off using NAT. NAT is simple, lighweight, works with most things, but isn't strictly by the book for TCP/IP networking.. (bending the rules slightly). It's very very common in small and home networks for sharing a Internet connection. For example NAT is what all those small "broadband routers" you can find in the nearest computer shop is mainly doing. The Windows proxy you used is most likely a SOCKS kind of proxy (or maybe a WinSOCKS proxy). SOCKS is a generic proxy method for TCP/IP and is quite well supported by most clients. WinSOCKS is an extended variant specifically tailored for transport level proxying of the networking operations of Windows applications. Difference between NAT and proxying is that NAT takes place at the packet level by rewriting the packets as they travel to/from the Internet, while proxies operate at the application protocol level (with the exception of SOCKS which can be viewed as sitting somewhere inbetween more like at the transport layer.. but lets not complicate things more than needed) As already mentioned proxies exists in two kinds: a) Application specific proxies like Squid who have deep knowledge of the specific protocol (i.e. HTTP) and adds extra features beyond simple sharing of the Internet connections. b) Generic protocol neutral SOCKS kind of proxies. Usually does very little besides just shuffling traffic and maybe a bit of access control on who may use the proxy. And then the third option is c) Or you could use NAT, without any proxy.
