Hey Guys.... See I have 2 X 512kb adsl routers (2 X ADSL Lines) and 1 switch... I use the manual connection to connect using a username and password. My routers are not configured to auto connect (I choose it this way).

I currently have both routers connected to my Switch... I dont think that helps much. I would like to make use both in my network with about 20 computers connected.

Any help would be appreciated...
 
I haven't tried doing that, Question though will 10 people be using 1 router, and 10 use the other?

Just thinking here that you could set up the first 10 to use Router A as their gateway, and the other 10 to use router B as their gateway.

If all will use either or both, then I'm not 100% sure but can mess around to check? what exactly do you want to do?
 
There is no easy way to simply connect two ADSL routers to a switch and distribute the load across the two lines.

You have two options:

1) Static setup
Configure half of the clients with the default gateway set to the internal port of the one ADSL router, and the other half with default gateway set to the other ADSL router. You can also set each client with a secondary gateway address of the other ADSL modem, to provide redundancy in case one ADSL line goes down. The maximum effective line speed will be 512KB.

2) Dynamic setup
The best recommended method is to buy a Dual-WAN router with auto failover and load balancing. All clients are configured with exactly the same IP information. Should one ADSL line go down - all the traffic will automatically be routed across the second ADSL line. The maximum effective line speed will be 2x512KB = 1024K.

Great stuff ! Option 2 sounds like a great plan... Mmmmm I wonder where one will get a dual wan router... any idea ?
 
:p Option one is what I said..

With option two are there any distributers in SA that you know of? I'm sure I know a few people who wouldn't mind setting one of those up?

I was looking for a dual-wan router a while back and found that D-Link had some.
 
Indeed Kalvaer - option one is your proposal. I was busy with the reply before you posted.

I was thinking the same thing the other day regarding distributors. To my knowledge there is no official distributors for these products yet in South Africa.

It will be relatively easy selling these products in South Africa. With bandwidth so expensive and Telkom's "best effort policy" on ADSL lines SME businesses suffer when their single internet connection goes down.

Different redundancy proposals:

1) 2x ADSL lines
LineA - Telkom 1024K ADSL - ISP A
LineB - SNO 1024K ADSL - ISP B

3) 1 ADSL, 1 Leased line
LineA - Telkom 1024K ADSL - ISP A
LineB - 128K Leased line - ISP B

With both proposals you don't have a single point of failure with the ISP and the physical internet link.
 
Thanks guys... on my journey I go seeking a Dual Wan Router...
 
How about ...

1 ADSL, 1 iBurst
WAN_A - Telkom 1024K ADSL Modem
WAN_B - iBurst 1024K Modem

Save you from any physical line failures ... like when the recent winds pushed over the telephone pole outside my house & snapped my cable.
 
@TitanKing :
We are investigating the exact same thing at the moment at the office.
What you need to do to pool connections : IP Source routing. Most hardware firewall devices support this - with the notable exception of the Cisco PIX. If you cant afford a hardware firewall, you can achieve the same results on an "el cheapo" server running Linux with IPTools2. You enable source routing on the external interface and balance it between the two gateways. It doesnt really matter what the connection type is - you can mixup ADSL and iBurst, V3g etc etc no problem.
Second (but not nearly as effect option) would be to VLAN your network via a Layer 3 switch and use NLB at the VLANs default gateway (on a switch that supports it).
Thirdly, you can split your network up manually as described above, but you will not get any automatic failover.
Hope this helps ~

PS-> Thanks to my boet for helping me out on this one...
 
Got me thinking

Does this give me 2*1024 = 2048 speed at 2*3G = 6G cap ???

Sounds like it, Is it worth it, cost ? or will a uncapped account be rather the in thing

where is the gurus's explain please..........
 
I was thinking the same when I first saw it Pupa.. At first I thought it would be like using a 6 gig account to only get 3 gigs, but that quickly left my mind as I realised it would be like opening two connections on a download manager and running each in its own "thread"

With uncapped accounts going out the window however, I dont see how its going to be possible, 2 X IS's accounts might, though I also dont see that being viable for the average home user and only companies "might" be able to take advantage of this

If its speed you want then these options seem to work nicely from what I've been reading up, Still cant find any clarification on Latency though?

Another thought I've had, what happens to incoming connections? ie: setting up virtual servers and a DDNS scenario? Cant find anything on that either?

EDIT I see Planet has one available as well http://www.planet.com.tw/news/productnews/XRT-402C.htm I'll be giving them a phone call first thing in the morning and I'll let you all know

Yeah..I will wait for Clipse and MrBeep to comment on a nice offering for ""Dual Wan" and price. Maybe worth the effort as this 1024 is a joke for small bussiness. I am planning to dump 1024 ADSL comes 1 Nov and get 192K adsl with my old Sat unless something is coming to the party.

Account wont get credited magically with 6GIG when making the dual wan connection with a dual wan router. It will simply added twice as much data onto your baby 3gig account :-)

Atm your screwed, a dual wan setup would just cost you more.. If you have endless cash, why not install 4x 1mbit connections and buy unlimited cap ;-) Endless cash = endless possibilities.

Majority of us aint so fortunate, so no.. This would be a pointless mission :)

ps. This is direct at kalvaer, 2/3/4/5Mbit adsl combined, wont drop your latency, if the multilinking method isnt 100% on the dot, which will be hard, the ping would infact start to become worse with the added multilink sessions.
 
Owww... I guess that explains why they are not sold in SA.. the distributers just want to rip us off. Welcome to SA, where Old technology is freely available at 10 times the price it was 20 years ago!

I"m still waiting for my contacts with Planet to get back to me, I've been informed there are 2 other Dual-Wan products available, just not sure of availabilty and cost yet in SA.

@ Clipse. Thanks, that is what I was worried about, I doubted that latency would in anyway decrease. Though the increase did seem very likely due to the extra functions involved :(
 
Almost forgot about this. I have found that these two are currently available in SA.

XRT-104D

and

XRT-402D

Pricing is also not bad and it goes from R1000 to R1600, excluding VAT. I can put you in touch with somebody if you want to get one
