I can connect via the dial-up number but my IP address is exactly the same as the fixed IP address of my home machine on ADSL.

That's a nice feature for when your adsl goes down -- you can dial-up, and still connect to any remote machines that have ip-specific access control.

...

Having connected via dial-up is there any way I can connect to my home machine as both machines then have the same IP address?

But two machines with the same ip address won't work. Perhaps your isp can give you a separate dial-up account that uses a different ip address.

Or you can find another dial-up provider. That's not a bad thing anyway, in case your normal isp is having routing problems. I use an 0845 service for that purpose, so I don't have to pay any standing charges for a service that I only use infrequently.

While I agree with the above reply, it set me wondering whether one could work a flanker by using dial-up on the laptop (assuming ADSL is connected to the home machine) and getting in via a network?

Regarding the same IP number, would the left hand on ADSL necessarily know what the right hand was sneaking in with dial-up?

Regarding the same IP, you can try it yourself: if on dynamic IP you can find it out from 'ifconfig' if not from your PPP software (e.g. kppp will tell you under "details"); if on static IP you'll know what it is anyway. Then telnet to that IP address. You'll find yourself talking to yourself, just like 'telnet localhost'. So, if you have two machines with the same IP, at the least each will be talking to itself, and this is bad enough. If it also succeeds in talking to the other (as well it might, since it's the receiver that recognises packets which have its own IP) then you're in real trouble! I think the suggestion of an independent connection which gives you a different IP is the only work-round.
