Hi hello to all. I am fighting with my configuration. 2 computers, one with 2 network adapters, one with only one adapter (main computer). 2 landlines DSL.
On the second computer (work unit) i need 2 internet lines for open chrome with one modem and opera or firefox with the second modem.
I renamed my both modems to two default gateways: 192.168.1.1 and 192.168.1.2 the other.
Besides this i need connection with Main Computer and Work unit via radmin remote control.
For now, i connected the 2 lan cables to the work unit, one cable from each modem.
The main computer is connected as second lan on one of the modems. No problems, i have internet on the main computer and remote connection with the work unit.
The work computer is configured like this; adapter 1:192.168.1.101 as computer address and 192.168.1.1 default gateway.
adapter 2.192.168.1.101 as computer address and 192.168.1.2 default gateway.
The main computer is configured like this: only one built in adapter: 192.168.1.100 computer address and 192.168.1.2 default gateway.

Why i have this complicated thing? because we can not get faster upload then 1mb, which i need for one site. since i have 2 sites open all the time, i need to open each site in another browser and want that each browser use one of the landlines. I have already installed forcebind ip and assigned each browser to the internet. But my network icon next to the clock, says always, one adapter internet access and the other not.
Can somebody give me a "dummy" instruction, how to do, please.
Thank you very much

It not normally possible to do what you want for two programs to use different connections. You have three options the way I see it:

1) Run some type of HTTP proxy server software, and force one of the browsers to use the internet through it. There was also some old free software called ForceBindIP that attempted to do this with some success.

2) You can set a static route in your system for a particular destination IP address (one of the websites), to use the second connection.

3) You can set a Virtualbox, then set it to use the second internet connection by default

Hi, hello and thank you for reply. I am using the first option already, but i would need the configuration in windows 10 for the both adapters, can you help? thx. (tcp/ipv4 configurations) if not possible for browser, maybe i can use the addresses of my used websites, i asume option 2, but i dont know how to do

For option one, the connection choice would need to be set at the proxy software, not at the adapter level. In other words, you'd set one of the browsers to go through the http proxy on your machine, and that proxy would reroute traffic through the second network card. The first card would be the default (with lower metric) for other traffic that is not going through that proxy.

By the way, each adapter should be set depending on what it is connected to (i.e. the gateway IP, DNS, etc.). According to your explanation, you have two network adapters configured with the same 192.168.1.101 IP address ? Each adapter should have different IP. Let's assume for the sake of argument that you have:

adapter 1 --> 192.168.1.101 (gateway 192.168.1.1, subnet mask: 255.255.255.0, DNS 192.168.1.1 or ISPs)
adapter 2 --> 192.168.1.102 (gateway 192.168.1.2, subnet mask: 255.255.255.0, DNS 192.168.1.2 or ISPs)

For option two, you'd need to set a static route to the IP of one of the websites. The command is something like that:

route ADD "network" MASK "subnet mask" "gateway ip"

where
- "network" is the address/range of the IP address of the destination website
- "subnet mask" is usually 255.255.255.0
- "gateway ip" is the IP of the gateway/modem/router that your network adapter is connected to.

For example, let's assume that you want your second NIC (192.168.1.102) to use the second gateway (192.168.1.2) to connect to website at 123.123.123.123

In command prompt, you'd have to use something like that:
route ADD 123.123.123.0 MASK 255.255.255.0 192.168.1.2

Once you're sure it works as intended, to make the route survive reboots you have to use the -P switch:
route ADD 123.123.123.0 MASK 255.255.255.0 192.168.1.2 -p

To delete the route:
route delete 123.123.123.0

I ran into the exact same issue years ago and started with 2 internet connections eventually using 3. My solution? The rv-series multi-wan routers by Cisco/Linksys. They were able to do the job very easily and with solid performance. There are many brands of multi-wan routers now, so you can take your pick. All of them can bind one connection to one service/destination IP/computer so you should be able to do what you want.
