iptables not loading commands

Hi, I am trying to do some iptables rules but the rules that are more important, they won't load.

I am trying to do

Code:

#iptables --table nat --append POSTROUTING --out-interface eth1 -j MASQUERADE
#iptables --table nat --append POSTROUTING --out-interface eth2 -j SNAT --to IPE
#echo 1 > /proc/sys/net/ipv4/ip_forward

Then I type #iptables -L to see if it loads, and I get nothing. I get no errors in the syslog

 

iptables -nvL

 

thank you very much jgedeon, both your advice as other I got from debian forums helped.

#iptables -t nat -L
