Mikrotik client for a Windows OpenVPN Server

Hello everyone,

I have a small network with a Windows OpenVPN server and several clients in different cities. Most of this clients are MACs computers and I used tunnelblick to connect to the VPN and the can see the shared folders of the Windows Server without any problem. Now, I have a MikroTik router that is a client for this Windows OpenVPN server. I already uploaded the certificates and did all the procedure required and the connection is OK and the routes for the OpenVPN seems to be correct. However, no one computer behind to the MikroTik router can see the folders that the Windows OpenVPN server is sharing. I suspect that is something related to a any firewall or NAT rule. But I’ve followed many procedures that are in different webpages without success.

This is the current configuration of my OpenVPN:

port 1194
proto tcp
dev tun
dev-node coco
server 192.168.137.0 255.255.255.0

ca ca.crt
cert imax.crt
key imax.key
dh dh1024.pem
ifconfig-pool-persist ipp.txt

push “dhcp-option DNS 208.67.222.222”
push “dhcp-option DNS 208.67.222.220”
duplicate-cn
keepalive 10 120
comp-lzo
presist-key
persist-tun
status openvpn-status.log
verb 5

Mikrotik OpenVPN interface:

Someone has any idea why I the computers connected to the MikroTik router cannot see any shared folder, but the connection is active?

According to your server setup you are using comp-lzo.

Mikrotik does not support LZO compression (unfortunately!!!).
If you can change this on the server side w/o a hassle you could try.

Thanks woro!!! It works!

Thank you very much woro! Your solution was the answer!
