This is
the current FOnline license in Russian.
Although it seems you want to provide the "FOnline software" for free, it would still be wise to clear it up with the owner (i.e. Cvet) first. In this case the controversial term would be 4.2, which basically says "User has no right to reproduce and distribute the Software for commercial purposes (for a fee), as well as to include it in compilations of software products, without written permission of the owner." If you install the (FOnline) Software on a remote server, you are already reproducing it, and that's OK. However, if you ask for server subscriptions, the amount of money from subscriptions may exceed the amount of money needed to keep the server running, so you begin to earn money with it. Not to mention that the subscriptions may be considered "fees" (no subscription => no play, if I understood correctly).
Furthermore, the issue with the Fallout IP owned by Bethesda Softworks LLC remains as a burden. There was usually no big fuss about the Fallout 1/2 content used in different non-commercial mods, games and projects, but
paid server subscriptions may attract a law shark as fast as you say "license". You may want to check their
legal terms before doing anything regretful.
I couldn't say more because I've got no experiences with subscriptions - we were running our server on donations, with a transparent accountancy to the FOnline owner.
