Chapter 53 Troubleshooting
UAG Series User’s Guide

My rules and settings that apply to a particular interface no longer work.
The interface’s IP address may have changed. To avoid this create an IP address object based on
the interface. This way the UAG automatically updates every rule or setting that uses the object
whenever the interface’s IP address settings change. For example, if you change LAN1’s IP address,
the UAG automatically updates the corresponding interface-based, LAN1 subnet address object.
I cannot set up a PPP interface.
You have to set up an ISP account before you create a PPPoE or PPTP interface.
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 UAG is not applying an interface’s configured ingress bandwidth limit.
At the time of writing, the UAG does not support ingress bandwidth management.
The UAG routes and applies SNAT for traffic from some interfaces but not from others.
The UAG 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 UAG.
• 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 UAG and the DDNS server.
