Okay, I have this: http://www.robsnetworks.com/index.php?spgmGal=Robs%20Ho... = network diagram of current network... I want to do this: I have a 3MB/768KB DSL Line through covads networks (earthlink = provider), with one static IP. I also have a 6MB/384KB Dynamic IP comcast Cable internet line. I want to be able to combine the 2 lines and have 1 network, and still be able to use my 1 static IP for the webserver, and basically have 9MB/1.1MB available for everyone to use, what dual wan router should i use? BTW... the server is attached to both networks now (that isn't shown in the picture only becuase i havn't changed the pic yet), and the server is doing the DHCP for BOTH networks right now. Thanks for any help

I'd stick with brand names: Linksys, Cisco, Buffalo, Dlink, when dealing with dual WAN ports. Prefer Linksys or Cisco though. Cisco will be a lot pricier as Linksys is their lower end SOHO type equipment.

* Hello Rob,

I was just about to mention Cisco gear but you kind of need a Cisco guru around sometimes to set them up and care and feed them. I used to do a tad bit of Cisco myself, although with all the SOHO type stuff lately you get real rusty.

I just ran across this on a quick search:

http://www.ispfailover.com/default.asp

I'm getting conflicting signals from their docs though as to wether a 4+ could do your 9Mb/s aggregate traffic. One doc said4+ could do 10Mb/s but on the web pages they seem to be indicating max 8Mb/s.

* Oh here is where I saw that:

http://www.ispfailover.com/compare.asp

You could call them and ask if a 4+ can really go up to 9 or 10Mb/s.

Their Pro 100 supposedly can go up to 100Mb/s. in case anyone would want to go crazy and try to build a T3 out of DLS/Cable Modem links.

* 4+ at around $2k

1+ at around $1600

(Apparently you can do this with a box with just 1 Ethernet 10/100 port. Just plug your two Internet Connections into one switch as well as the Powerlink Unit.)

* I think you have to have Static IP's on both connections though, especially if you are running your own web server inside. You also wouldn't want any NAT going on on the ISP router/modems according to what I'm seeing. The Powerlink units, it looks like, need the actual WAN address on the inside of those links. I guess not such a leap if a Linksys box is already getting the WAN IP on your cable connection. The question is what's on the inside of your DSL link? IS that modem a NAT router and your just forwarding ports for Server ports inside to a particular RFC-1918 IP address for the server machine?

from what i understand earthlink operates with a PAP service, which keeps comeing up in all my research... to be honest, i'm a cisco guy with great network knowledge, and i have never heard of PAP... now... the earthlink DSL connects via PPPoE... and it is static... now i HAVE TO use a brightport 8120 router with this earthlink, using: "i have a PPPoE username and password" option in the setup of the router, NOT "I have a static IP address"... now i'm assuming that once the PPPoE authentication goes through, then the Covad server assigns my static IP (68.166.249.35) (which is the address to all my websites on my server, and my ftp and whatnot), i called Xincom today asking about their 502 and 503 dual WAN routers and they said that both models support this PAP thing, AND the only way to get the whole 9 MB down would be to open 2 connections on the download (obviously)... and they said that as far as the static ip that is bound to the earthlink dsl is concerned, that the people accesing the server will still be limited to the 768kb bandwidth, and would not be able to get the whole 1.1MB only because you can't "forward", if you may call it that, the comcast 384 up over the 768 up dsl and get the combined bandwidth, the guy said that that wasn't possible. :? With the Xincom, the guy said that you would have to set up the brightport 8120 as a gateway, and program the Xincom to work with the brightport gateway. I'm thinkin, okay, fine, i know how to do that, but that still gets me nowhere as far as combining my bandwidth is concerned.

Yah well don't sweat the PAP. You might not be old enough to have spent a lot of time in Dial-Up Internet. Or didn't work for ISP's where you had to support it. I did all that and got several Tee Shirts.

Since a lot of DSL is doing either PPPoE or PPPoATM - Point to Point Protocol over either Ethernet or ATM frames...

The old stuff from PPP still survives, including Password Authentication Protocol and Challenge Handshake Authentication Protocol.

and

http://www.faqs.org/rfcs/rfc1994.html

for historical reference, and maybe:

http://www.tcpipguide.com/free/t_PPPAuthenticationProto...

if you really want to get bored to death. * I used to have to maintain the Unix boxes and the Radius Authentication Servers, as well as working on Lucent and other RAS servers. I knew more about this stuff than I wanted to know.

Anyway you might want to call those guys that I mentioned before and see if their load balancing box can handle what you're trying to do. I'll try to drop in here from time to time if you mention anything else on here. For now I've gotta get some shut-eye and hopefully go build some networks on boats tommorow...
January 24, 2006 2:12:43 PM

great, thanx alot for your help, have fun building networks on boats (I would like to do that everyday lol... and some toughbook installations as well) (I own a cf-29 toughbook :) )
January 24, 2006 3:06:17 PM

I would like to work on networks on boats everyday too :(  but we've been a little slow getting this season kicked off with the hurricanes that came through and all. But we're moving along.

What do you think about the new Mac on Intel thing? Dual Core Intel's instead of the IBM processors, right?

Mac OS/X pretty good now with a Unix core, right? (now I'm getting off topic for network and Internet). Macs darned good with networking too, can do anything PC can do and more I think. Macs getting a big boost in popularity with the Ipod and Itunes stuff.

You know, I actually don't like it at all. I've personally used the new 20" G5 with the core duo in it, and the performance is great, but most of the applications don't work at all... its horrible... simple things such as UT2004 won't run on it. I personally own a 2.1 GHz G5 20" Imac with 1 gig of ram, and wouldn't trade that for the core duo at all. I also think that Apple is making a big mistake when it comes to dropping the firewire from their basic, low-end notebooks. I used to own a G4 12" white ibook (800Mhz/640MB/60GB), and it had firewire, and i loved it... I would never buy a notebook from apple if it didn't have firewire... that defeats the point of having a nice multimedia apple computer.

Tom's Networking did a review on a routers that did just this thing about 6+ months ago. Do a search for there article you shoud findit.

You may also want to look into the symantec gateway series. Really nice firewall, with an add on card can do you wireless routing, and various other things. I have a 460r at work that I manage and like working with it. I know that there are some new models that weren't avail when we purchased have a peak at least the 460 has dual wan for sure and it allows you to bind some of the ethernet ports to specific wan ports if so desired. The 460r also has vpn client software so if you are away from home you could connect back to home easily and securely.
