After a firmware update with "keep all settings" from 1.02.3 to 1.12.3 the webui of the RUT240 is not accessible anymore. Browser says connection refused. Access to the Webui over IPsec VPN to the LAN IP worked before. IPSec VPN Tunnel is up and running. A Ping to the LAN IP gives a response. Access via RMS Webui is working. Tried with different browsers on different computers, but no luck. Any ideas how to fix this?
