I have 2 machines advertising the following routes:
- Machine A: 192.168.1.0/24
- Machine B: 10.10.0.0/20
All clients behind each subnet are able to communicate via the subnet routers just fine, until today when Client A (192.168.1.10, Linux 3.2.0 ARMv7) and Client B (10.10.0.3, Debian 10) stopped communicating with each other. As far as I’m aware there are no firewalls present on each client (no
ufw is inactive).
