The wireless security is not following the re-authentication timer setting I specified.
If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS
server has priority. Change the RADIUS server's configuration if you need to use a different re-
authentication timer setting.
I cannot configure a particular VLAN interface on top of an Ethernet interface even though I
have it configured it on top of another Ethernet interface.
Each VLAN interface is created on top of only one Ethernet interface.
The USG is not applying an interface's configured ingress bandwidth limit.
At the time of writing, the USG does not support ingress bandwidth management.
The USG routes and applies SNAT for traffic from some interfaces but not from others.
The USG automatically uses SNAT for traffic it routes from internal interfaces to external interfaces.
For example LAN to WAN traffic. You must manually configure a policy route to add routing and
SNAT settings for an interface with the Interface Type set to General. You can also configure a
policy route to override the default routing and SNAT behavior for an interface with the Interface
Type set to Internal or External.
I cannot get Dynamic DNS to work.
• You must have a public WAN IP address to use Dynamic DNS.
• Make sure you recorded your DDNS account's user name, password, and domain name and have
entered them properly in the USG.
• You may need to configure the DDNS entry's IP Address setting to Auto if the interface has a
dynamic IP address or there are one or more NAT routers between the USG and the DDNS server.
• The USG may not determine the proper IP address if there is an HTTP proxy server between the
USG and the DDNS server.
I cannot create a second HTTP redirect rule for an incoming interface.
You can configure up to one HTTP redirect rule for each (incoming) interface.
