In case you used Tunnel Traffic through Tinc before.

ip rule del from 10.0.0.0/24 table TUNNEL
ip route del default via 10.0.0.1 table TUNNEL

To route the traffic accordingly

echo '777 TINC' >> /etc/iproute2/rt_table
ip -4 route add 10.23.23.0/24 dev vmbr3 table TINC
ip rule add from 10.23.23.0/24 lookup TINC
ip route add default via 10.0.0.1 table TINC
iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

If you wanna run these automatically at VPN start put them into /etc/tinc/xxxx/tinc-up
