Model: ER7206 (TL-ER7206)  
Hardware Version: V1
Firmware Version: 1.10

Hi All, 

 

I can confirm with testing firmware 1.01 and 1.10 that NAT Loopback is broken in Firmware 1.10 angry

I have upgraded and downgraded the firmware multiple times but no way to get it working again. I also read from other users that it is not working anymore!!

 

Please FIX ASAP and do not wait again 1-2 months with a firmware release. This is a serious bug for me and I need this option restored.

My Setup:TL-ER-7206, OC200, 3x EAP245, 1x EAP225, 1x EAP225-Outdoor Wishlist: 1x TL-SG2218 and 2x TL-SG2008
