We had a subnet that was reachable through an OpenWRT-Router without problems.
Now we needed to increase the network, bacause we ran out of IP-Adresses.
So we decided to do a supernetting and included the subnet and changed the netmask to
That works intern just fine. But reaching clients on the 192.168.19. part of the network is not possible through the vpn-tunnel.
in server.conf we have changed the route to /23 subnet:

Code: Select all

port 1194
proto udp
dev tun
tun-mtu 1500
ca /etc/openvpn/ca.crt
cert /etc/openvpn/some.crt
key /etc/openvpn/some.key
dh /etc/openvpn/some.pem
crl-verify /etc/openvpn/some.pem
ifconfig-pool-persist /etc/openvpn/ccd/ipp.txt
client-config-dir /etc/openvpn/ccd
push "route"
push "dhcp-option DNS"
log /tmp/openvpn.log
status /tmp/openvpn-status.log
verb 3
Did we miss something else, that is necessary?

kind regards

Found the solution myself:
a firewall-rule, that allows the incoming vpn-traffic was set to changing it to, and restarting the firewall, did the trick.
