No...your reverse entries, behind your firewall, won't stop your systems
from being able to access the net from behind your firewall.
However, your initial question indicated delays when attempting to access
your server, and that those delays were alleviated by adding those
systems' IPs to your hosts file.
Placing those 250 entries into your zone file will help speed up their
access to the other systems on your network.
