Two internet connections with two vlans

I have an gs1900-48 with this firmware V2.40(AAHN.1)_20180705.
I have two internet providers and i want to make two separate vlans each with it`s own internet conn.
Because i want them separately i didn`t create a trunking port.
Vlan1 (default) is with all the corresponding ports untagged and excluded for the vlan2 ports.
Vlan2 have 2 ports tagged and the rest are excluded(or forbidden) for vlan1.
For vlan2 i have a router which provides dhcp but can`t receive traffic(including arp`s) and the port to the router is configured with pvid for second vlan2 and like i said no trunking.
It is possible to have 2 lines of internet and two vlans totally separated?

Thank you.

    Welcome to Zyxel Community!

    The goal can be achieved.
    Based on your description, please be ensure that the router is tagged out VLAN2 to GS1900-48.
    Or if the router is untagged out, you may just change the GS1900-48 port connected to the router to untagged and PVID 2.

    Hope it helps.

    Tnx for the reply but ... this is my config:
    and the vlan2 ports
    port 27 - internet
    port 28 - lan --> pc (network card is set for auto)
    If i connect the pc straight from router it works so dhcp on router works.
    I don`t know .. maybe i am missing something.
    Thank you.

    No traffic from port 27 (router) is coming out or is not routed to vlan2 ports accordingly.
    If i set this:
    from port 28 i connect to vlan1 and internet. So this does not provide any restrictions.
  • Thank you.
    So.. the config is like this (the one that worked for me):
    All the vlan2 ports are forbidden in vlan1 config (but don`t think is necessary. excluded are ok too i think)
    In vlan2 config all ports are set to untagged and in port config are set with pvid 2(for vlan2 in my case) and voila works like a charm.
    Thank you very much for answers.
