OpenVPN site-to-site Server can't reach remote network

[A999]

Hi,

I followed Wiki guide to set up OpenVPN Site-to-site normally, both client/server connected. The remote site can "see" server's network, but the opposite site can't. I already added iroute remote/sub network in "Client Specific Override", but I still can't ping remote addresses from server.

Can somebody help me to figure what's I have to look at? Thanks.
