Only default VLAN has Internet access (Packet Tracer simulation)

I've created network simulation with PT (my skills are really weak). Everything was ok and all PC's had no problems with automatic DHCP IP configuration (set on router) and etc. until I decided create two VLAN's on Cisco Switch. When I added all PC's to those VLANS - DHCP doesn't work anymore on them, no access to HTTP on those PC's. I simply only created VLANs, added ports, and made trunk mode from switch to router interface. Thats it. Obvious I need to configure something, maybe someone can help me with this ?

Btw if I remove PC from created VLAN's, it works fine on default VLAN.

Did you create a subinterface with tagging on the router, assuming it's router-on-a-stick you're trying?

 

I dont think so. This is my full router configuration:

You have only created access ports on your router. You will need to put a physical interface in trunk mode and work with tagged sub-interfaces.

Google "router on a stick". Here's an example:

Cisco Router-on-a-stick with Switch | Networks Training

 

Thank you for explanation

 

Ok so now after that "router on stick" thing I can ping and send packets from one VLAN to another, but still have problems to set DHCP and connect DNS server. As I understant I have to configure NAT, but wich interface should be inside - I mean Fa0/1, or as inside interfaces I should configure subinterfaces Fa0/1.10 and Fa0/1.20, Im bit confused at this point

 

ip helper-address

That's what you need
