Issue with access lan when remote network is the same subnet
outlet last edited by
I am using iOS with OpenVPN connect. Over cellular I can browse the internet just fine and access local resources, but if I am on a public hotspot with the same subnet as my home network it will always resolve to the remote network resources.
OpenVPN network: 10.140.0.0/16
Example remote network 10.0.0.0/255.0.0.0
I have force all traffic enabled and I push my local network in the advanced server settings.
Is there any way to get OpenVPN to default to my LAN?

Yes, that is an issue. If the network you are at (coffee shop, university…) happens to use a subnet that overlaps with your home subnet then there is trouble. If you are somewhere that has used 10.0.0.0/8 then that is a big pain! People should be setting up their networks with just small parts of that - 10.20.30.0/24 etc. Try to pick what you think is an obscure piece of private IP address space - 172.17.42.0/24 ... - for your home LAN and for the OpenVPN tunnel network.

you can 1:1 NAT your home-lan to a "virtual" subnet over your vpn.
hotspot_your_ip = 10.0.0.200
lan_host_you_wish_to_reach = 10.0.0.100 <<–- routing issue
1:1 NAT your home_lan to 172.18.1.0/24 -------- from hotspot_your_ip you'd then connect to to 172.16.1.100 | and the NAT would have you end up on 10.0.0.100 <<--- routing issue "solved"
i have a couple of sites where changing the lan-subnets is a ton of work (static ip's). I've used this method to circumvent possible routing issues
