DynDNS not function.

If the same IP address is recorded in your canonic name as dynamically assign
address, it means that the operator is using NAT or firewall.
NAT is possible to verify by the help of the ping on address of your server with
static IP address and by the help of the router address verify and address in ping.
Firewall is possible to verify, for example by remote access on web interface.
The operator doesn’t give out address DNS servers and without DNS server’s it
is impossible to connect to server dyndns.org. In log system will be this message:

I switched the router to offline mode by the SMS message, but the router is in online
mode after restart.
Control SMS message doesn’t change the router configuration. If the router is
switched to offline mode by the SMS message the router will be in this mode up
to next restart. This behaviour is the same for next all control SMS messages.
