Hi

I have a Asus RT-AC68U with asus merlin firmware.

I would like to know how to set up a vpn tunnel as follows:
My asus shall act as a VPN TAP client, BUT only a specific lan port must be assigned to use the VPN tunnel (lets say port3).
Doing so whatever devices are connect to this port3 (using a second switch) are managed by remote DHCP server (VPN server segment).

Sp my question is....how can I tell to asus merlin "this VPN Tap tunnel must be binded to lan port 3, all the others ports (1-2-4) have not to be tunneled " ?

many thanks
 
nobody know?

I wonder if something like this would be possible..... create a vlanA for Port 3 and a vlanB for all the other port.
then assign a tap vpn to vlanA

but I am not skilled in e tables and rules to create in order to do this.
 
Assign a TAP VLAN to vlanA
Do you actually need to use a TAP VPN Client?
I wonder if something like this would be possible..... create a vlanA for Port 3
If you can use a TUN VPN Client, then you could use something like:
e.g. Map switch Port 3 to VPN Client 1 VLAN10
Code:
./WiFiVPN wl0.1 1 autodnsmasq

./VLANSwitch.sh 10 3 vpn1 notag autodnsmasq
