I recently configured a Cisco 877W and i'm currently trying to make DynDNS work ok, so i can access from my office to my home computer.
The router seems to be updating my ip correctly (if i shutdown and restart my dialer interface, or if i restart the router, my record at dyndns updates and i'm able to ping it from my local LAN).
The problem is that from the outside (my office), if i try to ping my hostname i recieve a "Destination not reachable error". The IP is the correct one, but i've never been able to ping it correctly.
Could yoy please take a look to my running-config (see document attached) and see if i'm missing something?
By the way, in the running config, the updating method is not assigned to the dialer interface, because i want to solve the "not reachable" issue before enabling again.
Thanks in advance.
