Hey @shenek,
Finally I got to the openvpn configuration. I’d love to try this settings out. Unfortunately I’m struggling with routing whole traffic throught the router as well as fsteff.
What I tried so far:
/etc/config/firewall
---------------------------------------
config zone 'vpn_turris’
option name 'vpn_turris’
option input ‘ACCEPT’
#option forward 'REJECT’
option forward 'ACCEPT’
option output 'ACCEPT’
option masq ‘1’
#list network 'vpn_turris’
option network ‘vpn_turris’
---------------------------------------
/etc/config/openvpn
# My additional config parameters
list push 'redirect-gateway def1 bypass-dhcp'
list push 'dhcp-option DNS 192.168.1.1'
Doesn’t work yet. Don’t you have any idea how to make it work please??
