I need remote access to Cisco router 1603 via ISDN link. Exactly, I need to connect to router's BRI interface from any remote PC via ISDN line so that router can give me access to my LAN. When I call router's ISDN number it reject me because I don't have IP address. My problem is this: how can I configure router to give me one private IP address which will be associated with my username, so every time I call router, I get the same private IP. And would that solve the problem? I want to call router's ISDN number and connect to router. After authorization router should give me CALL BACK to number from which I call.
Router's specifications: System Bootstrap, Version 12.0(3)T System image file is "flash:c1600-y-mz.120-8"
Thank you.
