No. I just used Default IP address 172.31.98.1 for web access.
Network Set UP:
PoE Switch < ----- > IAP 205-H < ----- > Laptop
(172.31.98.1) (172.31.98.43)
Test Procedure:
1.Laptop connect to instant SSID.
2.Web access via 172.31.98.1 or it will be redirected to https://instant.arubanetworks.com:4343.
3.Webpage is not available
By the way I tried to two AP's in this same network set up and I successfully accessed the AP (IAP-205 & IAP-215) via GUI. Only in IAP-205H encountered this error and GUI access is not successful.
