ADSL Bonding

Guys hope you can help me, What is the best way to bond 2 or more adsl lines to increase upload and download speed, we currently use a Cisco 2621 for one ADSL line but I want to increase the speed, Can the router do this or do i need some thing else to sit infront of the router to do this.

Please could someone help me get this up and running.

thanks

If you have Windows 2003 Server in this scencario somewhere, it has a built-in load balancing wizard you can use to balance the load between two NICs with seperate connections. If you're talking about regular desktop machines, I'm afraid scampgb is correct.

Do you have a DSL WIC in the router, or are you getting an Ethernet feed?
If you have the DSL WIC's, then you can add another line and load-share between the two with the 2621 router alone. If you're getting an Ethernet feed from a DSL modem and plan to add another, there are many devices on the market that support dual-WAN connections.
Most firewalls have a SOHO model with dual WAN ports:
Linksys, Watchguard, SonicWall, Fortinet, ZyXEL Hawking...
Google "firewall dual wan" and you'll see what I mean

Linksys RV042/RV082 is my current model of choice...

Thanks guys for you help,

I am trying to conect two remote sites with the main site, and would like to acheive 1 meg down load and 512 upload. the device that will maintain these VPN tunnels will be a cisco Concentrator

So if I put another device in front would that give me 512 upload or two 256's upload I really would like 512, also if it did load balance over two adsl lines ie 256 upload would this cause any problems with creating a VPN tunnel because in my head it would seem I would have two source ip addresses ???

There must be a solution

If I went down the BGP route surely I would need to bigger routers than the 2621 to hold the internet routes ?

Les Moore

You're not going to get BGP on DSL links. Period.

what about multilink at the ISP and at our end, has anyone done this ?

Les Moore

Once again, not with DSL. Multilink PPP is not supported.
