Problem accessing WebGUI on M4300 switch
Hi, I had originally set up my M4300 switch as an L3 routing switch, connected to a VLAN unaware router/firewall (Fritzbox) provided by my ISP. In that configuration, I was able to access my swit...
FWIW, I've switched back from jumbo frames to the default frame size value and now I can access the GUI again.
@AGI,
Question: in the 'IPv4 management VLAN configuration', should 'Routing mode' be enabled or disabled (it is enabled in my case) ?
Disabling Routing Mode would globally disable routing on your M4300-28G-PoE+ switch. I suggest to enable it at all times.
I had originally set up my M4300 switch as an L3 routing switch, connected to a VLAN unaware router/firewall (Fritzbox) provided by my ISP. In that configuration, I was able to access my switch via any of the VLAN IP interfaces, including the one of my management VLAN 99 (192.168.99.254). The M4300 also acted as DHCP server for the different VLANs.
I now replaced the Fritzbox by a pfSense router/firewall, which will now take over the routing/firewalling/DHCP. So I disabled the routing and DHCP in the M4300 switch and set the IPv4 management VLAN configuration in that switch
Read your initial post again. Let us try this. Kindly try to set VLAN routing again on the M4300 switch (leave the firewall and DHCP functions on the Fritzbox router) and check if you will be able to access again the M4300 web GUI (192.168.99.253) from a VLAN 178 (192.168.178.0 /24) via wired & wireless connection.

You want me to enable VLAN routing for all VLANs in the M4300 switch? This is what is now handled by my pfSense firewall/router, which makes it easier to manage firewall rules.
Can the M4300 not be operated in 'L2 mode'?
Thanks.
AGI,
I apologize for the late response. I inquired your concern to the higher tier of NETGEAR Support. As per the higher tier of NETGEAR Support, do a packet trace on the PC where you cannot access the web interface, taken while you try to access the web-GUI of the M4300 switch but it fails.
To analyze the packet capture, kindly open a chat or online support ticket with NETGEAR Support here at anytime. Be sure to include the following details when you open a support ticket :
a. IP settings (including the default gateway) on the PC (where you cannot access the web interface)
b. an image showing detailed information on how everything is connected
