How is the default gateway in the client machines set?
My guess is:
a) The clients in subnets do not know that the route to another
subnet goes via the Linux machine,
b) There is a HTTP proxy in the Linux machine forwarding the
Web requests.
Another question: Is the way out from the subnets to the big
Internet via the Linux machine, or something else?
If this is a basic network tree, you should have in each machine
the default gateway pointing to the next step toward the Net.
You have now changed the next step from what it was.
