i have create an dyndns account and i trying to access my dynamic dns. i have configure dynamic dns service on my router(netgear DG834) appropriately. i still cant ping to the hostname. i am sure it has something to do with my firewall but i am not sure which port and what protocol (TCP, UDP, BOTH, ANY??) to use while setting up the firewall rule in order to be able to ping my hostname externally.
if i have to open up a port on the router, how would i link it to dyndns updater which is hosting the domain name and how to test it.
