If you are using stock k12ltsp as root from a terminal give command
"setup" Choose menu firewall>customize Set eth1 as non trusted device
(default) and then set allow http Save before quitting. The command
"service iptables restart" should do the trick. Caution assuming eth0
is ltsp network device always set this as trusted device other wise
ltsp network will also come to halt.
"man iptables" and edit /etc/sysconfig/iptables suitably and restart service.
In both cases take backup of /etc/sysconfig/iptables before
attampting. This way you can alsways copy back and come back to status
