block all incoming forwards
You have to allow for returning connections, if you block all incoming connections you are also blocking your wanted connections. Below is the default firewall rules and other necessary settings for it to work. You will see the section for Forward that allows Established & Related. This is what you are missing. You should modify your settings and/or the firewall rules to fit your needs. All Mikrotik Routers have this or similar as default and the reason yours does not is because it is a Switch (the "S" in CRS denotes this.) If your Internet speeds are much more than DSL speeds, you may have problems reaching those speeds.
