I discovered a problem with the automatic filter rules created for NAT rules. When copying a NAT rule, the associated filter rule for the new copy has it's interface hard coded to whatever interface existed in the origin rule.

Steps to reproduce:

1. Create a NAT rule, ensure that an associated filter rules is created.
2. Back on the NAT rules screen copy the NAT rule by hitting +
3. In the edit screen, change the Interface of the new rule (in my case I changed from WAN to OPT).
4. Save the new rule

Expected:
The new associate NAT rule (for the new filter rule) should be updated to reflect the change to the new interface

Actual:
The associated NAT rule actually shows WAN as the interface, and this cannot be changed.
