Same IP in local and remote Network. Can't reacht remote IPs

wlanrouter

Hello all together. I'm pretty sure its already answered somewhere but i used the search function and google and I just found something that couldn't help me. I use OpenVPN at work to connect to my home network. Connection works, internettraffic is 100% routed through the tunnel. But there are the same IPs at home and at work. If i try 192.168.0.10 for example its not routed through the tunnel and i reach the local network at work. What do i have to change in the Client config file?

dev tun
tls-client
proto udp

remote my.dyndns.org 50544

#float


#redirect-gateway
#redirect-gateway def1
#route-gateway 192.168.0.10
#keepalive 10 60

#redirect-gateway local def1
redirect-gateway def1

#dhcp-option DNS DNS_IP_ADDRESS
#dhcp-option DNS 8.8.8.8

script-security 2
ca ca.crt
comp-lzo
reneg-sec 0
auth-user-pass

Everything that i marked as a comment won't work.

Sounds like a network conflict .. I suggest you change your home network to a unique subnet like 172.27.73.0/24

First of all, thanks for your quick help. My home network is pretty big and the IPs are saved everywhere. Can i just redirect all network traffic through the tunnel?

Cant i just redirect all 192.168.0.0/24 requests to the VPN Server Gateway 10.8.0.14 ? I don't need the local network at work any more as long as I'm connected by VPN.

Technically: No .. with a but ..

Using:

redirect-gateway def1 block-local

will achieve what you want except for the Local default gateway .. See --redirect-gateway flags in The Manual v23x

The very best solution is to never use 192.168.0.0/24 and 1.0/24 (and other common networks) for your server side LAN.

Didn't helped. But i found out this was not the problem. The priority of the network connection on my computer was first "LAN Connection" and then "TAP VPN Connection".

Everybody with the same problem: You need to tell Windows to use your virtual network card "Tap 9" before your real "Network Card". Search Google how to change priority of the network connection.

And thank you very much "Traffic" for your support and help!

Or do it the Right way and resolve network conflicts properly by not having them in the first place ..
