hello ernestas
hmmm, we have about 15 of these cameras in use and i never had any problems connecting to them in LAN, WLAN or so. also, neither on pc, firefox, chrome, ipad or iphone.
as said, when i connect with my ipad to the rut router using wlan, i can access directly totally fine. see screenshot above (firefox on ipad, as your admin interface does not really work well with safari (drop down menues in main navigation don't work).
regards, lukas
