Allowing access

[bigdodo]

I have 3 machines on a network of about 35 that can not access the Internet but are on the Lan there is a mesage that access denied. How do I grant access. I am using a wireless router and a Linux server as gateway

What is your wireless router? It's possible that it's already working at capacity, not accepting connections from new computers became it simply can't.
