Re-route default BHM remote tun0

Apparently the route list is locked by the new-terminated remote access via
openvpn. And these are the steps to release our current ip and to set
the default gateway to current.

10.0.4.0             192.168.111.1   255.255.255.0   UG    0      0        0 tun0
10.0.5.0             192.168.111.1   255.255.255.0   UG    0      0        0 tun0
10.0.6.0             192.168.111.1   255.255.255.0   UG    0      0        0 tun0
192.168.2.0       192.168.111.1   255.255.255.0   UG    0      0        0 tun0
10.0.2.0             192.168.111.1   255.255.255.0   UG    0      0        0 tun0
192.168.1.0       192.168.111.1   255.255.255.0   UG    0      0        0 tun0     <<<
192.168.1.0        *                        255.255.255.0   U      2      0         0  wlan0 <<<
10.0.3.0             192.168.111.1   255.255.255.0   UG    0      0        0 tun0
192.168.0.0       192.168.111.1   255.255.255.0   UG    0      0        0 tun0
192.168.111.0   *                         255.255.255.0   U      0      0        0 tun0
default             192.168.1.1        0.0.0.0               UG   0      0        0 wlan0

I've marked down with <<< which are ip overlapping, every packet to
192.168.1.0 will be routed to 192.168.111.1 instead of 192.168.1.1.
And we have to fix this


$ sudo route del -net 192.168.1.0/24 gw 192.168.111.1


Done, hope it helps
