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:
– DynDNS daemon started
– Error resolving hostname: no such file or directory
– Connect to DynDNS server failed
IPSec tunnel is establishing but communication doesn't function.
Probably it is badly set up route conditionals of connected equipment or it is bad set
up GW.
FTP doesn't function.
Router doesn't support the active FTP mode, supports the passive mode only.
L2TP or IPSec isn't establishing.
Verify the reason in the log system.
How do I get to know that EDGE is functional?
If download is higher than 85.6 kb/s then EDGE is functioning.
I switched the router to offline mode by the SMS message, but the router is in online mode
after restart.
Control SMS messages don't change the router configuration. For example, if the
router is switched to offline mode by SMS message the router will be in this mode
up to next restart. This behaviour is the same for next all control SMS messages.
