NTH

Hi all,

I'm using the nth module for each connection it change of IP.
The scenario is:
--------------              -------------
| Server with | ------ > |    Server    |
|      NTH     |               |   Master    |
--------------              -------------
So, the users connect to "Server with NTH" and the .bashrc of the user has a 
ssh to "Server Master".
On "Server with NTH" has an interface, eth0, with 2 logics, eth0:0 and 
eth0:1
eth0: 10.0.0.2
eth0:0 10.0.0.3
eth0:1: 10.0.0.4
Above are the rules on "Server with NTH"
iptables -t nat -A POSTROUTING -o eth0 -d "Server Master" -m nth --counter 
7 --every 3 --packet 0 -j SNAT --to-source 10.0.0.2
iptables -t nat -A POSTROUTING -o eth0 -d "Server Master" -m nth --counter 
7 --every 3 --packet 1 -j SNAT --to-source 10.0.0.3
iptables -t nat -A POSTROUTING -o eth0 -d "Server Master" -m nth --counter 
7 --every 3 --packet 2 -j SNAT --to-source 10.0.0.4

So, at each connection to "Server Master" the IP is changed.
As NTH support only packet 0, 1 and 2 and I need to more IPs to be changed, 
if I add more a interface does it work ?
Thanks a lot.

Regards.
