Hi Everyone,
I'd like to access my Cisco 881 router from the internet using Dyndns, but I'm having some issues.
I configured Dyndns successfully on the router, it is sending its ip address to the dns server time to time as it should. However I can't ping the domain name that I registered, the PC is seeing the correct IP address however there is no response coming back. Establish an SSH session is also not possible.
Pinging ntsz.ddnsking.com [100.102.66.47] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
3g(config-if)#do sh int di1
Dialer1 is up, line protocol is up (spoofing)
Hardware is Unknown
Description: 3g access
Internet address is 100.102.66.47/32
I believe something trivial is missing from my config but I'm unable to determine what it is.
Below my current config:
