I have a router that I can't manage (it is an ISP thing). It is directly connected to a T2600G-18TS (let's call it X) switch. The X switch has a static IP assigned from the routers IP range. I have another T2600G-18TS (let's call it Y) switch that is connected to a X switch. It also has a static IP assigned from the routers IP range. Next I would like to have 3 VLANs so I followed this tutorial about DHCP relay click. The only change is 192.168.0.1 is the ISP's router IP and X's IP address is 192.168.0.9. Everything seems to be working, different ports assigned to specific VLANs get proper IPs etc. The only problem I have and can't resolve on my own is Internet access. When I connect directly to the X switch my computer gets IP address from the routers IP range and I can access the Internet. However, whichever VLAN I connect (using the Y switch) I get proper IP address (from VLAN), proper gateway, proper DNS (which I set up manually in the DHCP pool config) but when I try to ping whatever IP in the outside world (say 126.96.36.199) I immediately get 'Network unreachable'. Local connections are working. I feel that I miss some routing. So when I am connected to VLAN10 (according to the tutorial I linked) my gateway is 192.168.10.1 but I can't access the Internet. What route(s) am I missing?
I don't include any drawing or sachems as my network configuration is exactly the same as specified in the link.
