Unable to delete destination NAT rule
Closed, ResolvedPublicBUG



I tried to delete a destination NAT rule and got the following error. I was later able to delete the rule by deleting allt destination nat rules with the command: "delete nat destination"
Thankfully I only had the one destination NAT rule. :)

[email protected]# delete nat destination rule 100
[email protected]# compare
[edit nat destination]
-rule 100 {
-    description "wg to local lan nat"
-    destination {
-        address
-    }
-    inbound-interface wg01
-    translation {
-        address
-    }
[email protected]# commit
[ nat ]
