I'm currently playing around with a Cisco 819 LTE-integrated (C819G-4G-G-K9) router at my summer place to get a better LTE-signal and control that the ISP router provides me.
Currently I'm stuck at where the clients cannot ping internet (1.1.1.1 or 8.8.8.8) while the router is able to. The clients can ping the router.
- Client IP: 10.0.1.12 (VL20)
- IOS: Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.3(3)M3
If anyone would have an idea why this goes wrong, I would appreciate if you could help me. I have read the other similar posts without success.
