Send all traffic to next-hop

@Viacheslav
Thanks, but policy based routing seems not to be what we need as we do not like to define different routes based on the source of the traffic, at best based on the destination of a package.

We just want to shove out everything via 192.168.200.1.

For the more specific prefixes, my example already mentions more specific rules but shows that we miss exactly that range that starts at the bottom of the block.

Servers in the subnet in question are configured this way in /etc/network/interfaces:

auto enp198s0
iface enp198s0 inet static
  address 192.168.200.23
  netmask 255.255.255.192
  gateway 192.168.200.1
  up route add -net 192.168.200.0 netmask 255.255.255.192 gw 192.168.200.1 dev enp198s0

ip r
default via 192.168.200.1 dev enp198s0 onlink
192.168.200.0/26 via 192.168.200.1 dev enp198s0
192.168.200.0/26 dev enp198s0 proto kernel scope link src 192.168.200.23

Is there really no way to reach this ?
