When I first began using Tomato over a year ago on my WRT54GS router, port forwarding worked very well, and I could open or close ports with no difficulty at all. Now after the last couple of upgrades I find that ports cease at random to remain forwarded, and if I struggle long enough changing the port number back and forth between a new port and the original port, saving each change I can eventually get the original port to forward once again, but even then it eventually and at random appears to stop being forwarded. I tried opening a range of ports and found none would test opened, using www.grc.com/x/portprobe=nnnnn to test. Currently I have 6 ports forwarded in Tomato, all of which were displaying open less than 12 hours ago, and now only 1 tests displaying "open", 3 display "stealth", and 2 display "closed". Anyone know of a solution to this problem? edit: Testing the current opened port, 44432, in Tomato GRC.com shows it "closed". Unchecking and saving the "ON" box in Tomato GRC.com then displays the port status "Stealth", reapplying the check mark and retesting the port brings me back to "Closed". It appears that the longer this problem persists, the more difficult it becomes to get around. Previously it took only a few attempts to get the port to forward, and now it has become a several hour process of trial and error. Another port, 43222, remains testing as Stealth" no matter if the check mark is applied or removed.
