Deleting Unused Rules from XG450

Hello,

Greetings,

You may delete the firewall rule if there is no traffic passes through it. However, it is better to disable the rule for now and if you don't see any issues in the services. Later, you may go ahead and remove it.

Hello Stu,

Good day and thanks for reaching out to Sophos Community

You may refer to this doc guide about SF rules: https://docs.sophos.com/nsg/sophos-firewall/19.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/RulesAndPolicies/FirewallRules/index.html#rule-table-actions

Data Transfer count could give an insight if it’s being used recently and for troubleshooting. Also, there's a section in NAT rules that could give insight on usage on 

It's better to disable and observe first before completely deleting a firewall rule, then if any service disruption might occur you can then enable and reset data transfer count to know if there are any users traversing the firewall rule, from then you could make necessary adjustments.

Hope this helps. Have a nice day and thank you for choosing Sophos.

Cheers,
