Re: Denial of Service, Good for AS/400?

Jim,

I am presently testing the Linux (RH 6.1) firewall I set up a couple of
weeks ago -- hope to go "live" on the net in a week or two. We will be
running the website off our AS/400, but email is on the firewall. The
AS/400 is inside the firewall, and I have port forwarding set up to
re-route any and all appropriate requests to the internal IP of our 400.
We already have several people working remotely, who access the AS/400
via Client Access, through the firewall -- this last bit took a little
troubleshooting, as Client Access uses several non-standard ports for
different services (port 23 for telnet of course, but also several ports
in the 84xx range for things like file transfer and print services).
Basically, I had to just keep trying a remote connect, and check which
port was denied by the firewall, until I had all the required ports
open.

If you would like to see my documentation, just ask. It's a fairly basic
set of firewall rules based on the firewall how-to and the ipchains
how-to, with the addition of the things I needed for Client Access. I
will probably tighten the security as I go through this testing period.
