    It is a pfSense issue, not NETGEAR. Your ASUS router is VLAN-unaware so it works well with your NETGEAR switch in its factory default settings. However, you’ve created VLANs on your pfSense router. The pfSense port you were using needs to be added to the VLAN as an untagged member.

Hello Mooglestiltzkin 

Please tell me the topology you are using and how you have connected the switch.

And tell the switch model you are using currently,
Have you assigned any static Ip to the switch?

 

Have a lovely day,

    router (pfsense) > switch (GS728TPv2) > desktop
     
     
    switch static ip is set directly via the switch web ui. however to even do this, i have to setup and connect via my asus router. in that setup
     
    router (asus AC68U) > switch (GS728TPv2) > desktop
     
    once i am able to login to the netgear switch web ui which default is dhcp (works on asus, but not pfsense no idea why), i then configure the static ip (change from the default dhcp) in the netgear web ui. Apply.
     
    then replace back to the hardware back to the original setup
    router (pfsense) > switch (GS728TPv2) > desktop
    now the switch web ui is accessible. Before it wasn't until i made this change.
     
     
    So question is, why wouldn't dhcp work before on pfsense, but works on asus 😕 ?
