Four Public IP

Discussion in 'DD-WRT Firmware' started by manuele, Mar 10, 2006.

    Hi everyone.
    I've recently bought a WRT54GS V4.0 and I'd love to use my router to set the bandwitdh on every ethernet port cabled (4).
    I have a cable modem and four public Ip address and would set my router to give 40% of bandwith to one ethernet port and 20% to the other three ports...
    Is it possible to do that with original firmware or should i upload dd-wrt?

    Who is your cable modem provider that provides up to four public IP addresses?

    I believe it is possible with either. DD-WRT has some optimizations for QOS and a little more flexability. As far as percentage goes, there are a few ways you can allot bandwidth usage on either setup. However DD-WRT is so much better than the original firmware in so many other ways, I would suggest it either way.

    Is it possible to assign a public IP to each individual port? I didn't think that was possible.

    I have 5 public IPs and would love to do that too.

    Thanks for your reply.
    I'll load dd-wrt.
    May you explain how to configure my router to achieve my needs?

    Well, what exactly are you trying to do? If you use the linksys router you will only need one public ip address. The router will allow you to adjust bandwidth to each port on the router. Are you wanting to have more than one public IP? I believe WRT54GS is limited to 1 public addresss.

    Thanks for your reply.
    I need to use four different public ip address.
    I use the first one for a mail server, the second one for a web server and third and forth are used by servers of my friend (co-paying ISP bill).
    I don't need to use my router to surf the web from my small lan, but only to set a % of total bandwith on each public ip address.

    Thanks again!

    If you are using all 4 servers for different purposes, you could set up the router using one public address and port forward each protocol to the desired server. This would also be a good security precaution. If you have more than one web server, this may not work for you though.

    I need to use each public ip address with all port range available.
    One server is mine, the other not and son on.
    Still possible?

    Sounds like your running your own mini ISP, lol. I don't think the WRT is capable of doing what you need.

    I would love to use my router to do that... running a mini ISP and selling % of the total bandwidth i have.
    Nobody knows if is it possible?

    Doesn't Italy have some requirement about registering ID of all use Internet customers? I think that is why FON has trouble operating there. Take a look at FON.

    I will not sell my bandwith to natted users, only to four server that will use four (paid) public ip address...

    I think it might be possible. I have been reading a few posts on the DD-WRT forum, and some people have configured their WRT to use two ISP's. If this is possible, I don't see why you couldn't use the VLAN in conjunction with IPtables to do QOS between essentially 4 VLANs. It will be a bit of work, but it may be possible. Another solution would be to build your own router from an old PC. Then you could pretty much do whatever you want. It might be a better solution since you are running 4 web accessible servers.
