If you need to replace a ‘Standard OS’ Sonicwall with an ‘Enhanced OS’ Sonicwall there is a webpage to allow you to convert an exported config to the right format to then import on the new device

I tested it from a TZ170 to an NSA220 and it worked well.

SonicWALL – Bandwidth Management

Firstly create the address objects i.e. create the subnets that you want to bandwidth manage:

Optional: Then the object group to group them all together

Next go to BWM under Firewall Settings and BWM, then change the type to Advanced:

Next go to Bandwidth object and create an object and choose if you would like a guaranteed bandwidth and your max bandwidth:

Next create a Firewall Access Rule:

On the access rule,

From: i.e. where the traffic is coming from in this cause our internal LAN.

To: The internet or WAN

Any port and service,

Source: our new subnet group.

Destination: anywhere on the internet

Users Included: All

Users Excluded: None

Schedule: Choose a schedule to manage the bandwidth

Finally choose the logging and extra security:

Next go to BWM and choose your new Bandwidth object.

Note Egress is bandwidth “out” and Ingress is bandwidth “in”:

o confirm anything is in place you can check you access rules.
1. A filter symbol means BWM is apllied
2. A clock symbol means it is scheduled.
