Looking for a few good Anandtech-ers with a Linksys WRT54GS.
As you can guess, I have a Linksys WRT54GS wireless router...one of the original 1.0 versions with speedbooster. Behind this router I have my standard set of machines with dedicated IP's and a set number of IP's for additional devices to acquire IP leases dynamically via DHCP should I bring them home. One of these machines with a dedicated IP is my Debian file server. This machine is headless and without keyboard. It just sits in the corner of a room and hums along. I use SSH to remote into the device to perform maintenance, shutdown, restart, etc.
My question is this. I would like to know if the WRT54GS can be configured with "unassigned" WAN facing ports (such as 7468) to forward to "assigned" ports such as 22 which is used for SSH. In this way I can leave the default settings for SSH on the Linux machine but have 7468 as the SSH port when connecting from other computers on the Internet. My goal here is to reduce any script kiddies or other malicious code from being able to target the well known port 22.
In the Games & Applications setup you can find port forwarding and port triggering. It appears that you can only forward by port range. See this link. It gives a start and end to the port range. This appears to only forward a range of ports to the destination IP which is not really what I want to do. Do I need a hacked firmware version to accomplish this?
