Recently upgraded to the latest Beta and I was browsing some of the newer features.
I noticed the addition of "Automatic packet filter rule" under the DNAT/SNAT options.
I'm testing this feature out. I removed one of my packet filter rules, then enabled the "Automatic packet filter rule" option for the corresponding NAT rule.
I checked back in the packet filter rules and nothing has been added (bug? normal? No idea).
If this is normal, it would be nice to have some type of "entry" in the packet filter list. Perhaps with the options grayed and a note mentioning that this packet filter was automatically added.
It would also be nice to enable the option to log traffic for automatically created traffic filter rules as well.
