how to unblock connections coming from a NAT boxB

how to unblock connections coming from a NAT boxB

[Vidya Ravipati]

I have a question regarding how to unblock the incoming connections
from the source NAT box.
If I have source machine behind the NAT , how should I configure my
iptable rules to unblock the connections coming from that particular host
only.
1) How should I specify my rule to unblock only particular host behing the
source NAt only
2)How to unblock the particular host behind the particular NAT box (can
allow the connections from other host behind the same NAt also)

Thanks

I am sorry , but I can't fully understand what is your problem .
So I just guess the situation :
You hava a machine which is connected to the Internet and a LAN .
You want to block some machines in your LAN from accessing the Internet
and meanwhile allow some of them .

Am I right ?
