Hello, I currently work with ipchains to setup NAT from my private network to the internet. Before getting to the MASQ line I had a few forward rules for letting a few stations to get to a server in my DMZ with their original IP address intact (i.e. not NATted). I need to do this to allow those stations to work the X-protocol with the sever set in my DMZ. I have tried to upgrade to iptables. No matter what I have tried those stations go out with the NAT address. After having studied the flow charts of how a packet traverses the chains it seems to me that I am out of luck and no matter what I do the packet will end up in the nat table of iptables and therefore its address will get masqueraded. Am I wrong? Can anyone tell me how to aviod masquorading those few stations when working with my server. The SNAT will not do since I need to preserve their original address. If I am not in the correct place for asking this question I would appreciate it if someone would point me to the right forum. Thanks, Reuven __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - File online, calculators, forms, and more http://tax.yahoo.com
