I have a seismic measuring device with GSM and VPN and FTP capabilities and an in-built webserver.
In an ideal scenario the device connects to the internet via GSM and I access it's webserver via VPN to start measurements.
When running unattended, it sends data to our FTP-server, which is not identical to the VPN server.
My Problem:
All the individual components work well enough. It established a VPN connection on the mobile network and I can access it from a desktop with the OpenVPN client.
Without VPN, it sends FTP data to our servers like it should.
But the moment I enable VPN, the FTP transfer stops.
Is there a way to configure the OPVN server in a way that FTP traffic doesn't use the VPN at all?
Or alternatively, what do I need to do to make FTP work with VPN?
My VPN-server is on a Raspberry Pi2 and I set it up using
this install script.
The openvpn/server.conf looks like this:
local 192.168.1.2
dev tun
proto udp
port 1194
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/server.crt
key /etc/openvpn/easy-rsa/keys/server.key
dh /etc/openvpn/easy-rsa/keys/dh1024.pem
server 10.8.0.0 255.255.255.0
# server and remote endpoints
ifconfig 10.8.0.1 10.8.0.2
# Add route to Client routing table for the OpenVPN Server
push "route 10.8.0.1 255.255.255.255"
# Add route to Client routing table for the OPenVPN Subnet
push "route 10.8.0.0 255.255.255.0"
# your local subnet
push "route 192.168.1.2 255.255.255.0"
# Set your primary domain name server address to Google DNS 8.8.8.8
push "dhcp-option DNS 8.8.8.8"
# Override the Client default gateway by using 0.0.0.0/1 and
# 128.0.0.0/1 rather than 0.0.0.0/0. This has the benefit of
# overriding but not wiping out the original default gateway.
push "redirect-gateway def1"
