"Cannot attach to services manager" isn't an error you would expect for a straight database connection. What are you actually trying to do from the remote client?

Show us the connection string you are using to attempt the remote connection. Make sure you mention whether the host server is running Windows or a POSIX OS, as the syntaxes are different.

Try a tracert to the Firebird host IP address, too. That should help to establish the last IP address in the route.
