I have an 1841 router that gets it's internet-facing interface's address by my ISP's DHCP server. How can I use that address in an ACL, in a way that it will stay effective when it gets a new leased address?

If your question is ACL needs to bind the ip address assigned from your isp and it should change automatically when ip address changes then i think you cannot configure access-list to reference to the DHCP assigned ip address dynamically.
Hope to Help !!
