Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.1.1 0.0.0.0 UG 202 0 0 eth0
default 192.168.43.1 0.0.0.0 UG 303 0 0 wlan0
192.168.1.0 * 255.255.255.0 U 202 0 0 eth0
192.168.43.0 * 255.255.255.0 U 303 0 0 wlan0
I can remove the 192.168.1.1 entry with:
ip route del default via 192.168.1.1
This works, but after reboot this line comes back. Any idea how to permanently have it removed with Debian-based distributions?
