GS750E: Device with one MAC but 2 Ports and Subnets on 2 VLANs , ARP issue?
Dear community, I have just replaced two GS724 with a GS750E as I was not using most of the capabilties of the GS724 anyway. The thing I was using is port based VLAN. I have a router providing 2 se...
Hi there,
Thanks for the reply. I absolutly did untick the ports and even tried pinging from one VLANed port to the other (using the appropriate network config). That failed, so isolation works.
However I have solved my issue:
I have been using the "port-based" VLAN option (Advanced) and ran into problems. I am now using real "802.1Q" VLAN (Advanced). What I did is:
- VLAN-Configuration: Create VLAN ID "100" and VLAN Name "Isolate"
- VLAN Membership: Tick all ports I want in VLAN "Isolate". I am not tagging so I took the "U" option. Apply.
- VLAN Membership: Untick the above ports from default VLAN 1. Apply.
- Port PVID: Set above ports to PVID "100"
Cheers

Hello Lukas,
Have unticked the ports you intend to use on the VLAN 2 in the VLAN 1? This does not happen automatically.

Cools, using 802.1Q VLAN would have been be the next suggestion - that's the only thing we deploy on our networks, and such an issue would have caught us many times.
It would be worth opening a support case with Netgear so this suspect issue on the Port based [Basic and?] Advanced VLAN is reviewed by the Netgear engineering. Probably Christian_R can arrange the short-cut for this, thank you Chris!
