HTTP port to the Internet blocked

Hi!

I have a serious problem on my home "Linux" network. I have two
computers: mandriva and asplinux. mandriva is directly connected to the
internet. All the ports work that means I can use different messengers,
read and send mails and access HTTP and HTTPS websites. asplinux is
connected to the internet through mandriva. On asplinux, I cannot access
any Internet websites but the "Apache" websites from mandriva on the
ports 80 and 443 are accessible. Why is that? I have no
firewall in neither machine. I have tested to connect asplinux directly
to the internet and then the HTTP sites have been accessible but not
through mandriva.

There is also another problem. Lately I messed with NFS and "Samba"
servers in order to share out all the partitions on both computers.
After restarting mandriva many services do not start automatically like
sshd, httpd, xinetd... I have to start them manually although the
services are marked to start automatically. Earlier were also HTTP
Internet sites
accessible from asplinux through mandriva. I guess that file sharing
servers messed up something but I cannot find out what. Can somebody
give some advices what to do?

Sounds like you are forgetting to set up masquerading on your
Mandriva-box.

You will need some sort of firewall on "mandriva" to provide
"masquerading" for "asplinux".

This suggests that you have put something in your NFS and/or Samba startup
scripts which is hanging and causing the rest of service startup to stall.
This may also be causing the script which used to set up the iptables
rules for masqueradinf not to be run. Start off by disabling these new
services and see if it goes back as it was before.
