Hi everyone, I am trying to save a OVPN Server configuration on my MikroTik.

I have seen a few "how to" about the subject and I fill everything just as asked but when I try to save, nothing new appears on my PPP and no error is pointed.

Any contribution is welcome and I already apologize for any mistake (I know newbies, just like me, make a lot of mistakes).

Did you create your certs? Don't know if it helps, here's a few lines from my working ovpn server config to compare to your own:

/ppp profile
add local-address=192.168.X.1 name=ovpn remote-address=vpn-pool
/ip pool
add name=vpn-pool ranges=192.168.5.10-192.168.5.125
/ip dhcp-server
add address-pool=vpn-pool interface=bridge name=vpn-DHCP

/interface ovpn-server server
set auth=sha1 certificate=Server cipher=aes256 enabled=yes \
require-client-certificate=yes

/ip firewall filter # for ingress 1194
add action=accept chain=input dst-port=1194 log=yes log-prefix=_ovpn \
protocol=tcp src-port=""

/ppp secret
add name=user1 profile=ovpn service=ovpn

sometimes ... if ...

nothing new appears

... nothing happened ?!
.
you like to see a new ppp-interface ... why ? if you setup a new (ov)ppp-server ... only the capabiltiy for such an interface is born (goda** I'm biblic today)
.
good old atheists would check with an "/export" before and after ... if there's something they've done ... or beware god ! they've been ignored.
