I am testing now firmware RutOS 7.5 (RUT2_R_00.07.05_WEBUI) with Teltonika RUT240 and I have noticed that I cannot configure any longer option Bridge interface with “LAN as WAN” interfaces.
I’m navigating in GUI to Menu ‘Network’ → ‘LAN’ → ‘Lan interface’ - then switching to 3rd tab ‘Physycal Settings’ where I have Bridge Interfaces turn: on.
However, when I want to add another interface in the drop-down list, by default I have only eth0 and I want another (wan) eth1 I cannot do this - I get an error: Physical interface “eth1” is already being used by wan
Take a look at the screen:
I tried to check also Tab 'WAN’ tab and edit that interface wan to find some clue and maybe turn off Bridge interface there (I thought some active and enabled settings might collide), but with no success.
Currently I have nothing plugged-in to wan interface.
Any ideas? Or Maybe something was changed in newer software.
