Glenn,
look at this solution ; ( tested and worked very fine )
1st ISP 2nd ISP 3rd ISP
DSL DSL DSL
| | |
| | |
--------------------| | |-------------------
| | |
HUB ( not switch )
|
Any Router that support OSPF to make load balancing to these 3 links
|
|
Your internal network
Note :
1- The collecting links device should be hub , not switch ( to avoid STP )
2- configure the OSPF on the router to include the three links in the same area, so it will load balancing any request to any link, and no link will be dedicated

Yes, you could do something like this:
ISP1 ISP2
WAN1 WAN2
| |
[NetGear FVX 538 Box1]
|
LanFromBox1 ISP3
WAN1 WAN2
| |
[NetGear FVX 538 Box 2]
|
Int LAN
ISP1 and ISP2 go into NetGear Box 1. You would want that guy to be in ?Fail-Over? mode. Use DDNS just on 2 providers for inbound. LAN from NetGear Box 1 goes into WAN1 on Netgear Box 2, with ISP3 going into WAN2. This guy would be in ?Load-Balancing? mode. All published services come from WAN1 on Box 2, which are already redundant because of Netgear Box 1. Multiple HTTP requests would be LB between the combo of ISP1+ISP2 as ?one leg? with ISP3. All internal users go to NetGear Box 2 for access.
Only drawback (if it really is a ?drawback?) is that there is no LB on the ISP1+ISP2 leg coming into WAN1 on the Netgear Box 2. But that?s OK- you just set the ?main? connection on Netgear Box 1 to the fastest ISP.
The boxes are only $350 a piece ? and you can get the model one under the 538 (338?) even cheaper if you don?t need P2P VPN capabilities in-box. That?s actually a pretty cool topology for under $700 in hardware. You know, I?ve got an extra FVX538- I think I?ll order another DSL and do just that. ;)

Ok, I know what the first question the customer is going to ask, can they be cascaded ? combining 3 lines in 2 steps ?
I suppose they can, but are there any draw backs that jump to mind ?

Right- should have said that... The Netgear FVX538 provides 2 WAN connections, not 3.

Havent seen a 3-way (maybe before i die! ) but there is a nice little netgear floating around that apparantly does a good job. I'll wait for thor to chime in with the details, I looked at it and it seemed to do most of what i wanted. Might be a start

A little off topic, but I'm sure that someone on this list will have done this before.
A customer wants to combine 2 or preferably 3 ADSL2 lines together for the added bandwidth & more importantly the reliability factor.
They can get 3 ADSL services from 3 different telco's, which supposedly use different equipment at the local exchange.
What's the best way to bind them together.
There will be inbound VPN & SMTP so the public DNS entries will have to cater for the multiple public IP's, but that easy stuff.
I found multiple hardware & software solutions on the WEB, but nobody I know who has actually used any and can tell me the un documented holes, or the one that just work, and those that really work well.
Has anyone done this ?
Any suggestions ?

Ok, ok don?t cry, you can finish with that poor customer.
Anyway, my proxy starts working without any apparent reason. I restarted the firewall as Jim told me and nothing, and about an hour latter I discover it was working again.
I?ll see if this happen again.

Oh, excuse me sir. Let me drop everything including the work I am doing for a client that was robbed and I am trying to get them back all up and running to attend to your problem that you expect free instant help on.
Gees, what did you do take lessons from Andrew?

Hi ISAList
I?m having this issue and I have no idea why, I will appreciate if somebody knows what is going on.
We have a website https://vwa.msc.us <https://vwa.msc.us/> that is published on 12.32.217.149.
From outside everything work fine, but from inside I?m receiving the following error:
Network Access Message: The page cannot be displayed
Technical Information (for Support personnel)
- Error Code: 504 Proxy Timeout. The connection timed out. (10060)
- IP Address: 204.251.15.190
- Date: 7/17/2006 4:42:49 PM
- Server: njisa17.interlink-intranet.net
- Source: proxy
If I ping the website, its resolving fine to 12.32.x.x but the error is showing another IP.
If from my proxy server (njisa17) I ping the website, the address returned it is also correct.
So, where is ISA keeping that wrong IP?????
Thanks for all your answers.
