No access from remote networks

For a project, I've been given a Fedora Core 2 box on which to run CVS,
Apache, etc. However, this machine is accessible only from boxes on
the same subnet (SSH, ftp, web work from within, but not from without).
It has a public (129.x.x.x) IP, and the network admin has assured me
that the issue is not on his end.

My /etc/hosts.allow file is allowing ALL:ALL at the moment, and
hosts.deny has no entries. There is no firewall running at the moment.
Yet I still have no external connectivity.

I would appreciate any advice you folks can give me on how to track
down the problem.

Thanks.
Bill

For starters, you should see if you can tcptraceroute to various ports on
the "outside" somewhere, after checking "/sbin/route -n" to see if you can
even get there.

Then check tcptraceroute results from the outside to the 129.x.x.x ports
that you've opened.

It's likely all you are only missing a default gateway, try
'netstat -rn' to show your kernel routing table. You can
manipulate using 'route' ('man route'), see your distro
documentation on how to set it permanently, once you know the
default gateway and it works setting manual. Ask your network
admin for the IP of the default gateway on your LAN or look it up
from the working systems, also check if subnet-mask/etc is fine.

Good luck
