[ALUG] A connection conundrum - can it be done?

I have a laptop which I take on holiday and would like to use it to connect to my machine at home. My machine at home is on ADSL and my ISP also gives me a dial-up number. 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. 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? Am I missing anything obvious here?
