Hi.
I can agree, having the same issue.
Updated my server from 2.5.7 to 2.6.6 (2.5.7 is fast compared to 2.6.6).
Tried upgrading my existing environment (2.5.7->2.6.6) AND made a fresh install, directly on 2.6.6. Both won't work stable for me.
Clients connecting fine, receive an IP (10.x.x.x) and can "sometimes" ping a server.

As said: clients can connect without problems but can't reach any internal ips.
No errors in log.
Help is really appreciated (rolled back to 2.5.7 which works well and fast [so far]).
Thank you in advance.
Best regards
