I recently upgraded my Tomato 1.07 WRT54GS v2.0 to 1.09. I have been having a strange problem with one of my port redirects that was not present in 1.07. I run an FTP server on a non-standard port, so that it doesn't get hammered. I have it set so that Tomato forwards this non-standard port to internal port 21. Up until now this hasn't been a problem. If I reboot the router it works again, but only for about an hour, then stops working. Any idea what could be causing this?
