GS105Ev2 setup vlan100 to connect cable modem to Synology RT2600AC WAN port

Hi,

I need to connect my GS105v2 Prosafe switch between my Arris CM8200 cable modem and my Synology RT2600AC Router . I need to do this because the WAN port on the router has to have a VLAN of 100 for my internet to work so I intend to use the switch to provide the vlan tag. I tried plugging in the GS105E directly into my laptop to use the configuration utility provided by Netgear for the switch but I get the message "the switch and manager IP address are not on the same subnet"  I am trying to do this while  the switch and laptop are not connected to the internet ie the switch is connected directly to the laptop.

Has anyone done the same thing?

    I recommend you post the managed switch forum for help and information on how to configure this switch:

    https://community.netgear.com/t5/Managed-Switches/bd-p/business-managed-switches

     

    in most cases the VLAN taging would be done after or @ the main host router. Some routers support vlan tagging as well. So you would put the router between the modem and switch. 

     

    Check with the switch forum to see what is best suited for this configuration.

      THANKS FURRYe38,

      we had to set a static IP on the computer to match the pre-configured IP address range of the switch.Since we connected directly to the switch (without router) we did not receive an ipaddress from the dhcp server and as a result the switch and laptop were located in different subnets.

      The synology RT2600AC does not support VLAN Tagging on the WAN Interface. Our ISP (NBN/HFC) requires a VLAN to tagged so we the GS105Ev2 was placed inbetween the Arris Cable Modem and teh Synology Router.

      For others facing teh same problem here are some instructions:

      - We configured a static IP address on the switch in case we need to get in in the future and changed the default PW for security reason

      - In the VLAN settings 802.1Q Advanced we created VLAN100 and associated switch ports 1 & 2

      - We tagged Port 1 with VLAN100(T) and connected it to the cable modem

      - We Un-tagged Port 2 with VLAN100(U) and connected it to the Synology Router

      - IN Port PVID settings I assigned VLAN100 to Port 1 & 2

      - We Excluded Port 1 & 2 from the dfeaut VLAN(1). The Netgear webgui shows this as an empty box, other switches may show an (E) here

       

      Going forward we will be able to manage the switch from Port 3,4,5 only.

       

      In the synology Router, please ensure that any VLAN settings (VOIP, IPTV) have been disabled, so that the WAN Interface(s) won't send any VLAN information to the modem.
