Configuring Firewall And Nat Allowing Utm Offload On The Ar4050S - Allied Telesis AR Series Technical Manual

Setting up and Configuring UTM Offload
Configuring Firewall and NAT allowing UTM Offload on
the AR4050S
The following is a simple configuration for firewall and NAT allowing UTM Offload.
Configuration notes

Rule 30 will allow the device to access the Update Manager.

You need to configure a DNS Server address to allow communication with the update manager.

The offload device synchronizes the time from the forwarding device. This ensures log messages
are correctly time-stamped. Therefore, NTP is configured on the forwarding device (AR4050S).
