I have a PC with ROS 3.30, in a VMware server. I already have a standard hotspot setup.
But now i wanted to set a VLAN interface on the ethernet interface, and set up a different hotspot there.
The problem was that hotspot login page did not fully load. I understood that it was a MTU problem. Both physical and VLAN interfaces had an MTU of 1500.
I had to reduce MTU to something like 1480 and it started working like a charm.
Is this a known problem? Is it specific of 3.x?
