    I've filled up all my Port Fowarding spaces on my WRT54GS and I'm trying to figgure out how to get more of the spaces or combine a few of the others but I don't really want to open port ranges like that I've included a pic so hopefully someone will have some ideas...Aaron

    There's at least one space you can save already. 29900-29900 and 29901-29901 are fowarded to the same IP address - that could easily be range 29900-29901 without any loss of security.

    The other thing you may want to look into is simply grouping your applications. Give your machine ports (random example) 5000-5200 and set its services to use those ports as needed, then gets 5201-5400, etc etc. That way, each machine has a small set of known ports forwarded, and you just allocate those by machine.

    Since the port forwarding entries are just creating iptables forwarding entries, you could also simply have a script that dumps in all the forwards you need.

    Using the latest version of HyperWRT. So with the setup on grouping to the 5000 - 5200 ports that would involve going in and setting the specific application to those ports... which with some of those games are impossible to do to my knowledge. Is there another verson of firmware that would allow me more slots to add more ports?

    I'd look into IPTABLES scripts, then. A good start of a discussion on the subject over at HyperWRT forums:


    You haven't stated what firmware you are running, but with that many fields, I'd say it's a HyperWRT build. ;)

    I did state that about three posts up :)... but I switched to dd-wrt last night and it looks like I can add as many as I want... I havn't tested it very fary yet but so far I like it.
