OpenVPN doesn’t use remote gateway by default

openvpn

I've setup an OpenVPN server, clients can connect without any problem, but they still use their existing internet connections, and still have their existing public IP's.

How is it possible to basically set "Use default gateway on remote network" to TRUE, on the OpenVPN client side?

Thanks in advance!

You need to set the appropriate server side settings to push the default gateway to the clients. This isn't really a client side setting. Although I suppose you can manually modify the routing table on the client but that's not something that the average user will put up with.

This is documented on OpenVPN's website here. http://openvpn.net/index.php/open-source/documentation/howto.html#redirect

Just add "route-nopull" to the client openvpn config, then all pushed commands from the server are ignored. To get access to the local net, you must now add e.g. "route 192.168.5.0 255.255.255.0" to the client openvpn config, if the local net you want to connect to is 192.168.5.0/24.

Openvpn – Gateway gets stripped from DHCP Reply through OpenVPN tunnel

According to OpenVPN documentation
server-bridge is a shortcut expression for

mode server
tls-server
push "route-gateway dhcp"

and

server-bridge nogw is a shortcut expression for

mode server
tls-server

Interestingly push "route-gateway dhcp" activates a DHCP-proxy that stripes out the default gateway option in DHCP response from the original DHCP server. This can be seen in OpenVPN log
daemon.notice openvpn[4879]: Extracted DHCP router address: a.b.c.d

Your solution would be to use server-bridge nogw and the DHCP response contains the default route option again.
