[K12OSN] WhiteBoxLinux K12LSTP Test NAT problem....

[Rich McCue]

Adam,

I checked iptables and get:

[root at dilbert ipv4]# /sbin/iptables -L -t nat
Chain PREROUTING (policy ACCEPT)
target     prot opt source           destination

Chain POSTROUTING (policy ACCEPT)
target     prot opt source           destination
MASQUERADE  all   --  anywhere        anywhere

Chain OUTPUT  (policy ACCEPT)
target     prot opt source           destination

Is that what I should be getting?

I also checked the  echo 1 > /proc/sys/net/ipv4/ip_forward  and it is 
there with the value of 1. 

I also restarted the nat service.  How can I tell if it is actually running?

Thanks for your help.  I'm getting stressed out over this one.

Rich

>>I'm running WhiteBoxLinux on a server for a small office, some users have thin clients and others have fat Windows clients using NAT to get out to the internet.  I applied a large group of patches yesterday and rebooted the server over night and the NAT (Network Address Translation) has stopped working.  I tried reinstalling the nat-0.0.3-1.k12ltsp.1.3.1.noarch.rpm package to see if that would fix the problem, but it did not.  Any ideas on where I should look for the problem?  Here is the lengthy list of the packages that I upgraded yesterday. Any help would be much appreciated as my fat client users are clamoring for the internet:
