OpenVPN with Cloak on GL-MT1300

Greetings Gurus,

I've installed and configured cloak client on my GL-MT1300 (fw 4.3.19) to obfuscate openvpn traffic. The ovpnclient on the router seems to be connecting fine to the ovpn-as via the cloak proxy, however client's traffic doesn't make it through the tunnel to the outer world (I've set 'Global proxy' as the proxy mode). I can't reach any public hosts from the client machine, names are not resolved and ECMP doesn't get through. The only interface I can successfully ping is the 'Client virtual IP'.

What can be the approach to troubleshoot this connectivity issue?

Many thanks in advance!

PS The very same ovpn profile works fine on the windows machine with the cloak running locally, meaning that there are no apparent server-side issues neither with the cloak server nor with the ovpn-as.
