The test entry name "MasqAction" is duplicated on lines 39, 40, and 41. While this follows an existing pattern in this file, Ginkgo test entries should have unique names for better test identification and reporting. Consider using more descriptive names like "MasqAction with ToPorts", "MasqAction fully random", etc.

The MasqAction implementation supports both ToPorts and MASQFullyRandom features simultaneously (line 313 in actions.go appends fullyRand even when ToPorts is set), but there is no test case covering this combination. Consider adding a test case like: Entry("MasqAction with ToPorts and fully random", environment.Features{MASQFullyRandom: true}, MasqAction{ToPorts: "32768-65535"}, "--jump MASQUERADE --to-ports 32768-65535 --random-fully")
