setting up vlans affected communication

[johncenashia]

i have a simulated network of two branches connected to a internet service provider. i set up and configured vlans in each branch but in doing so the pcs in each branch can no longer access thier web server and the isp web server. tried setting up static routes to help resolve this but it did nothing, have absolutely no clue how to fix this. anyone help?

Hello,

for the VLANs to work, you need to configure subinterfaces on the router. I have made some changes to your router config (marked in bold), I have also added DHCP pools for each VLAN (for the sake of simplicity). I have also attached the revised file:

Hello @johncenashia 

Here are some extra informations about sub-interfaces, called Router On a Stick 'ROaS'.
