After USG5300 UTM products complete the configuration, AV/IPS feature library has been unable to update online.
1 Login firewall by WEB ways and then enter the configuration page;
2 In system->network->NDS, set the DNS server.
The inspection processes are as follows:
1 The route configuration of firewall is correct and the firewall can ping gateway;
2 Relevant packet filtering has been opened;
3 Relevant LICENS and activation code has been type into the device;
At last we found that the AV/IPS features library can’t updates online is for the reason that the DNS server hasn’t been set on device.
We should pay particular attention to if the DNS server has been set on the device when the features library of USG5300 UTM products updates online fails.
