WAG54GV2 Multi-NAT With Block IP Addreses?

    Can the WAG54G V2 be used in a "multi Nat" configuration?

    I have a block of public static IP addreses of which I need to use one on a server at home. Can I then take one of my other addreses and use NAT to distribute to 5 or so other work stations? These must be on a different public IP to the server.

    I know it can be done using a Wag45g and a basic Broadband router to deal with the second Private NAT network. But this would loose the wireless ability on the Private LAN.

    I would prefer to do it all within one box which I believe Zyxel, Draytek, Speedtouch and Westell routers will.

    Any help or ideas would be appreciated.

    Regards Dominic

    The short answer is no, the WAG54G can either act as a gateway, (NAT on) or as a router, (NAT off), not both. In a router configuration one of the public IP's would be assigned to the LAN side of the router, which the server would be connected to. You'd need to add in another router to provide NAT to the LAN clients, assuming you don't want to do this through the server. Of course the wireless facility will be pretty much redundant.

    Personally I'd get a bog standard ADSL router, something like the D-Link DSL-504T, and connect that to a Linksys WRT54G. Should provide everything you need :)

    Thanks for your reply matey.

    I was expecting it to be the case. I have tested my theory today with a basic broadband router handeling the NAT Private LAN. and it works great.

    Unfortunatly I alreday own the WAG. I think I can get a WRT for £50 which isn't to bad and the bonus is i believe they will stack together.

    Does the WRT have a good reputation? unlike the WAG and is the wireless range better than the WAG?

    Cheers Again

    Yes, but you can check for yourself by looking in the WRT54G forums here ;) It also benefits from several alternative firmware projects :)

    Its looking like I may be in the market for one then! Cheers for your help! I believe they can be purchased for around £50 in the UK which is better than coughing up for a Draytek or similar that will do the "Multi-NAT"

    I will have to research the relevent forum. Any versions to avoid? and any good places to look to buy one on the CHEAP LOL

    Thanks Again. Dominic

    Just to let you know I now have a WRT54G handeling the NAT traffic on my private lan, this is coupled to the WAG54g and the whole package is working great.

    I upgraded the WRT to the HYPERWRT firmware and boosted the power level up to 100% which has much improved the coverage. Doesn't seem to get excesivly hot unless you try to stack the two routers together as linksys inteded.

    Cheers for your help lads.

    Hi, are you sure this is the case? We are currently facing this problem at work (due to upgrading to an ADSL2+ internet plan). We are currently looking for a ADSL/Router or just a router that can handle multi-nat.

    On Broadband buyer, it lists the WRT54G as *not* being able to do multi-nat.

    Are they wrong?

    No they are correct, the WRT54G also isn't a ADSL router which is why I suggested using it conjunction with another router ;)

    The setup would be something like this :-

                                     |~~Public PC
    ADSL line ---- Router1 -|---------------------WRT54G--[ Network
                                     |___Public PC

    DSL-504T are u mad or something .. that router took me 5 times exchanging it and it still didn't work it had firmware issues and d-link doesn't do shit about it !!! and they knew about it from oktober 2004 !!! after a half year of exchanging this router and complaining to there helpdesk, i got refunded and bought me a linksys, but apparently there not beter with firmware only difference tho they attempt to fix it .. and dlink doesn't do shit except exchanging it !!

    so yeah if you like a new router each month and a crap connection go for it

    Heh calm down 8O I just said a bog standard router like the DSL-504, I wasn't telling everyone to rush out and buy that specific model, which I think is discontinued now anyway :roll:

    As for reliablilty, I've installed several DSL-504G's and they are all working fine :p
