Hi,
Could you tell me NAT behavior type of RouterOS?
I found the description for default configuration, but I want to know NAT behavior type based on RFC4787.
http://wiki.mikrotik.com/wiki/Manual:Default_Configurations
NAT is defined four behaviors on RFC4787.
- Mapping Behavior
- Port Assignment Behavior
- Filtering Behavior
- Hairpinning Behavior
I’m not Mikrotik user but new ISP (under discussion) has chosen MikroTik RB750GL2 as router.
I had already asked ISP engineer staff, but they have no anwer 
(They may use only default settings)
Here is other company routers.
±---------------------±------------±---------------±--------------±------------+
