hello All,

after updating, I can boot thinclients without issues.

But laptops / workstations that are also on the lan cannot connect 
connect to the outside world, e.g. ping 8.8.8.8

* root@centos-server ~]# /sbin/sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

* ltps-server-tweaks gives me :

[root@centos-server ~]# ltsp-server-tweaks
About to overwrite your default iptables (firewall) configuration.
hit Ctrl-C if unsure.

and hangs, even is firewall = off.

* here is my /etc/sysconfig/iptables:

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*nat

Can anyone offer further advise on this?
