GS1200-8 802.1Q VLAN: Must all ports be connected to VLAN 1?
I wanted to separate a PC into VLAN2, but it should also be able to connect to the same internet router as for all other devices in VLAN1. I set the PVID to 2 for this PC/port and set untagged for VLAN2 and unconnected for VLAN1. Also I put the the internet router as untagged in both VLANs. But with this it cannot connect to the internet router. If I also set for this port VLAN1 untagged it works. With this config I am still not able to ping the other devices in VLAN1 as intended. It is now working, but I find it strange that the VLAN2 port must also be connected to VLAN1. Also I am not sure if I opened a backdoor that can be used by malware to reach my devices in VLAN1.
Is this the way how it should work or did I something wrong?
