ESP not a valid protocol for firewall rules

[scrubby]

Hi,

I noticed that esp is not accepted as a protocol when creating a rule. When checking the code I saw that more existing protocols are also not accepted. Why aren't al available protocols accepted by the rule module?

Each protocol requires different input validation. The developers are focused just on the features they need. PRs are welcome.

Actually, as of commit 439a6c3 (Jan 18, 2020) esp and many other protocols are accepted. Reopen if you still have some issue with the esp protocol.
