Hi,
In our office we have Cisco 1721 working on 2 ADSL lines. Both these two interfaces get dynamic IP from ISP. I am very far away from office, therefore, whenever I need the connect to Router, they call me from office and give IP addresses then I am being able to work on router. Moreover sometimes I need to connect router when there is no one in the office. Is there any way solve this problem? Is there any way to be informed about IPs whenever they cahanges.
One may advice me to use AUX port, but I am at University dorm, telephone connection is unidirectional, they call me but I can't. the only availibity is Internet connection through LAN.
