Vlan Internet

[pistorioed]

I have created several VLANs, specifically VLAN 10 receives the internet from a Telecom router with address 192.168.1.1. The problem is that only the vlan in question browses. The others, despite having activated IPV4 Routing, do not receive a connection. Could someone help me, any support would be appreciated. Thank you

Hello,

Could you provide a diagram and configs of your devices? There is not enough Information to answer this.

If not you can try to check the following:

Can other VLAN devices ping their default gateway? Are the subnets set up correctly and are devices getting IPs?

Are the other VLANS allowed throughout the e L2 domain up to the L3 device?

Does the L3 device know about all the other VLAN subnets?

Is it a router on a stick configuration or SVI? Make sure if router on a stick then subnets and encapsulation VLANs are made appropriately.

Hello
sounds like you have a switch connected to your wan rtr which is performing inter-vlan routing and not another rtr so unfortunately the other vlans you have on this switch won’t be able browse the internet because those other subnets will need to be network translated and most switches don’t support NAT so unless you administer the wan rtr and able to append your current nat to accommodate the other subnets or introduce a rtr in between  the wan rtr and this switch those other vlans won’t have internet access

Likely overlapping with David's and Paul's posts . . .

What's your device and where's the "activated IPV4 Routing"?

If your VLANs and "activated IPV4 Routing" are on your L3 switch, the problem probably is, your Telecom router is only "aware" of one internal network, 192.168.1.0/24.
