Solved How to create virtual interface on AsusWRT?

[Freewill0592]

I am trying to create Ipsec Site to Site VPN on AsusWRT Merlin router but I am strugling to create routing for the VPN, VPN is connected.
Normally I used vti interface to create route based traffic, but no matter what I try I am not able to create any virtual interface on the router
I tried also gre, as I think vti is not available on the current AsusWRT kernel?
Any suggestions are much appreciated.

me@asus:/tmp/home/root# ip tunnel add gre1 mode gre local 172.29.29.6 remote 172.29.29.5 ttl 255
add tunnel "gre0" failed: No such device
me@asus:/tmp/home/root# ip tunnel add gre0 mode gre local 172.29.29.6 remote 172.29.29.5 ttl 255
add tunnel "gre0" failed: No such device
me@asus:/tmp/home/root# ip tunnel add gre0
add tunnel "gre0" failed: No such device
me@asus:/tmp/home/root# ip tunnel add gre
add tunnel "gre0" failed: No such device

me@asus:/jffs/scripts# ip tunnel add vti1 mode vti local 172.29.29.6 remote 172.29.29.5
add tunnel "ip_vti0" failed: No such device
