Running ADSL connections in parallel

[booswig]

Does anyone know if it will be possible to run 2 ADSL connections in parallel (with a second line of course).

My current connection is only 512MB, but I host a game server as well as a forum on my line, and when there are more than 60 people connected, latency starts increasing.

We were discussing the possiblility of getting a second ADSL line, with the necessary hardware and even software, that might enable us to double, even triple the current bandwidth.

Anyone know if this is possible, and what software/hardware will be required.

i would think that it is possible on some of the ADSL packages since they allow more than one simultanious sessions.

1 mbit ADSL will be released within the next month or two, you may just want to hold on until then.

Can be done with linux and some mods, or you can get a dual router.

the way that router works wont work in SA, multilinking is not enabled and that router basicly multilinks the 2 adsl modems onto a single public ip.

to multilink, the routers on both ends of the links need be configured for it. Just doing your end is not going to help much.

can be done very easily, you just assign 2 IPs is in your dns name. that way clients will randomly pick an ip address. So you simply have 2 ADSL modem routers and use NAT/virtual server on the router to point port 80 on both to the same ip on your lan.

are you using dynamic dns? that may be the trick, to get a dynamic dns provider to assign 2 IPs to the same hostname.

It can be done. But its a 2 part problem, and a linux based system will be your best platform.

1) getting your incoming connections to pick the correct IP address.
Using dynamic DNS, set up 2 hostnames. One for each connection.
Then using a normal DNS setup (ie: not dynamic), set it up so that a query for the hostname resolves with 2 CNAME's (those being the 2 dynamic hostnames)

2) make sure that traffic goes out the same interface it came in on.
Under linux, set up 2 extra routing tables (1 for each interface). Set the default route for each interface to force the correct source IP.
Then use a rule to make sure the traffic goes to the correct table.

Good luck

Get a HOTBRICK!!! You can load balance adsl lines with different ISP's even.
