SettingCheck
SettingCheck is a safety function for industrial users using a secure router. It provides a double confirmation
mechanism for when a remote user changes the security policies, such as Firewall filter, NAT, and
Accessible IP list. When a remote user changes these security polices, SettingCheck provides a means of
blocking the connection from the remote user to the Firewall/VPN device. The only way to correct a wrong
setting is to get help from the local operator, or go to the local site and connect to the device through the
console port, which could take quite a bit of time and money. Enabling the SettingCheck function will execute
these new policy changes temporarily until doubly confirmed by the user. If the user does not click the confirm
button, the EtherDevice Router will revert to the previous setting.
Firewall Policy
Enables or Disables the SettingCheck function when the Firewall policies change.
NAT Policy
Enables or Disables the SettingCheck function when the NAT policies change.
Accessible IP List
Enables or Disables the SettingCheck function when the Accessible IP List changes.
Layer 2 Fiber
Enable or disable the SettingCheck function when the Layer 2 filter changes.
Timer
Setting Description Factory Default
10 to 3600 sec. The timer waits this amount of time to double confirm when the
user changes the policies
180 (sec.)
For example, if the remote user (IP: 10.10.10.10) connects to the EtherDevice Router and changes the
accessible IP address to 10.10.10.12, or deselects the Enable checkbox accidently after the remote user clicks
the Activate button, connection to the EtherDevice Router will be lost because the IP address is not in the
EtherDevice Router’s Accessible IP list.
