Hello community,
I recently built a router on a stick for the first time using a custom router/firewall device. This device will handle all layer 3 activity, acting as a dhcp server for a Cisco sg-350 switch. Thus far, all of the machines can communicate with others of the same vlan, but none of them can access the internet.
Also this network is double-NATed because I need the features of the custom device, but I’m also forced to use the ISP router. This should not be a problem because this network only needs internet surfing, software installations, updates, etc.
Below is a device in vlan10 - IP address 192.168.10.10. It can ping the 192.168.10.1 interface, but not the internet. I suspect a routing table problem, but I've tried every configuration imaginable. I’m 110% sure the firewall isn’t blocking the traffic. Unfortunately I cannot post any files (no internet), and had to write this from a different machine. Any feedback would be greatly appreciated.
