Python error when deleting nat rule
Closed, ResolvedPublicBUG



I'm evaluating Equuleus version and it seems to throw a nasty error when I'm deleting a NAT rule. Below is the relevant config and error.

[email protected]# sh | comp
No changes between working and active configurations
[email protected]# del nat destination rule 1001
[email protected]# sh | comp
Possible completions:

[email protected]# sh | comp
[edit nat destination]
-rule 1001 {

  • destination {
  • address
  • }
  • inbound-interface eth0
  • protocol all
  • translation {
  • address
  • }
