Morning Hann,I would recommend upgrading the firmware to 7.7.1.11 or 7.9.5.1The current version of code is many revisions behind.Based on the country code those channels should be available.
Looking over the NAT guide and reviewing the article you sent, I don't see anything close or equivalent to reflection/Hair pin Nat as an option.I will assume this is not possible with the WiNG RFS controller.Please note:RFS is not a dedicated firewal...
Morning adf10,You should be able to find that information in the how to guide below.https://community.extremenetworks.com/zxxfm75553/attachments/zxxfm75553/ExtremeWireless_WiNG/8221/1/WiNG5_NAT_How-To.pdf
