Hi, all. My situation is: the gateway(Linux 2.4) imposes NAT on all the traffic from all workstations(configured with public IP addresses rathar than private ones) within the LAN. Now I want to set an exception in the NAT rule. That's to say, I want the gateway not to do NAT on *one specific workstation* within the LAN. Could you HELP me on how to do that? I'm quite sorry that I haven't had a good reading on iptables docs. But I'm not likely going to configure iptables other than this time since I'm not an network administrator. I just got the temperory approval from the network administrator who has been busy and gave me the root password to configure the gateway myself. I only want to enable the sshd on one Linux workstation within the LAN so that I may login to do some work when I am far from the LAN. Thanks in advance.
