Hi everyone.., i m using internet of Hathway.But they give u dynamic IP address and read ur MAC address,so connection can be used on only one PC. Is there any chance to share this connection on another PC.?through switch or another LAN card??..

You have two choices I can think of. One is to multi home the PC that's connected (which is to say, put dual NIC's in it) and then use ICS (internet connection sharing) or, you could use a SOHO router. If you check before purchasing, you can buy a SOHO router that is capable of 'spoofing' a MAC address. That's just a funky way of saying, you can change the MAC address (seen by the ISP) to whatever you want. So, if you went that route (and I'd recommend it) you buy the router. You open a command prompt window on the PC connected to the internet. You type ipconfig /all and write down the MAC address (Physical Address as it's reported by ipconfig). You then start the router and connect to it with the PC and go into the management interface and then change the MAC of the router to that of the PC. Then you hook your internet to the WAN port of the router, your PC (and any other clients you may have) into the LAN ports and everything should work just fine.

I prefer to use analox's free proxy application. It allows that one registered computer to "proxy" the service to any number of devices even linux or other OS's. Be sure to read your agreement with the ISP before you go farther. Most of the time they seem to allow it if you purchase their router. Seems kind of crooked. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

I don't know where you live jefro, but here in North America, no ISP or provider can control what equipment we hook up inside our houses to their modem....period. They can try, but thanks to a competitive market, if they try, we can simply tell them where to go and where to stuff the final payment and then we switch to a different provider that doesn't try that. The OP can do what I suggested very simply and easily and the ISP has no way to know that they've done so. And this negates having to use some crappy proxy software which would still require a switch at the very least and multihoming the PC with the proxy software on it to get more than one PC/laptop connected.

I am impressed. You have read every ISP's agreement in the world already. Cool. A proxy application runs on the host computer. No extra software or hardware is needed if you have two nic cards. A realtek card goes for $5 to share connection. ISP can only read that MAC address it was connected to. Could go to the trouble of getting a router and they are cheap. Clone your mac address, check with isp to be sure of connection type and authentication.

Well, I think using a router is the best way of sharing internet. Connect the router to the ADSL modem (I guess it is a broadband connection). Now perform the settings in both the computers for the router. After that one can access internet from either/both of the computers without the need of the other computer to remain switch on. A router normally houses for computers. The other technique is by ICS (Internet Connection Sharing) in which case the ADSL modem is connected to the host computer and the client computer accesses the net by ICS simultaneously. In this case no router is required but if you want to access the net from the client computer then the host computer has also to be kept switched on. I use the former method in my home and the latter method in my office. Abhijit

I am impressed. You have read every ISP's agreement in the world already. Cool. I don't need to....I'm very familiar with multiple ISP's throughout western Canada (from personal experience) and I have knowledge of several of the biggest in the US. What I said above is true for all of them. A proxy application runs on the host computer. No extra software or hardware is needed if you have two nic cards. A realtek card goes for $5 to share connection. ISP can only read that MAC address it was connected to. Could go to the trouble of getting a router and they are cheap.

Jefro, I was doing this as far back as 1993 when a good friend of mine opened up his own dialup ISP and hired me to help him set it all up. I've forgotten more about it than you're likely to ever know. Heck, I helped beta test a proxy software package back when (before the days of SOHO routers). You try to make it sound hard to plug in a SOHO router and change the MAC address on it but I'm sure even you could do it (well ok, in all honesty, I'm not really sure you could). It's infinitely more complex for someone who's not a computer geek to open the box, add another NIC, configure it, setup ICS or some other 3'd party proxy software (which of course would have to be installed first). I guess you'd know that if you'd ever done either. I know I have, many many times in my life. Given the option, I'll always go with the easier solution in a case like this, and that's a SOHO router every time.
