cisco – VLAN Configuration with out inter-vlan routing however with Web entry


I’m making an attempt to arrange a number of VLANs on my Cisco Catalyst 3850 change and join them to the web utilizing a TP-Hyperlink AX20/Asus RT-N12 router. I would like this setup to have a number of remoted networks with completely different Ip ranges in a approach that gadgets in every vlan can’t talk with different vlans however all of them have entry to Web. Nevertheless, the routers do not appear to help VLAN tagging (802.1Q), and I’m questioning if it’s attainable to attain this setup while not having a extra superior router.

My Present Setup:
Swap: Cisco Catalyst 3850 24T

VLANs created:

VLAN 10: 192.168.10.0/24
VLAN 20: 192.168.20.0/24
VLAN 30: 192.168.30.0/24

Every VLAN has an SVI configured with its respective gateway IP:

VLAN 10 SVI: 192.168.10.1
VLAN 20 SVI: 192.168.20.1
VLAN 30 SVI: 192.168.30.1

The routers don’t help VLAN tagging or subinterfaces.
Its LAN IP is 192.168.1.1 (assigned manually) and is linked to a trunk/entry port on the change.
DHCP: DHCP swimming pools are configured on the change to assign IPs within the VLAN ranges routinely.

Downside:
Gadgets in every VLAN can talk inside their VLAN however they can’t entry the web.
I believe the difficulty lies with the routers incapability to acknowledge VLAN site visitors. Because it doesn’t help VLAN tagging, it will probably solely route site visitors from a single subnet (VLAN 10 on this case).

only for take a look at I even enabled Inter-VLAN routing on the change utilizing ip routing.

Query:

  • Is it attainable to arrange this configuration with out changing the router with a extra superior one which helps VLANs?
  • If sure, how can
    I configure the change and router to make it work?
  • If no, what would
    be the only, cost-effective method to allow web entry for all
    VLANs?

Any recommendation or insights could be significantly appreciated. Let me
know if extra particulars are wanted.

Thanks prematurely!
