I have an Ubuntu server that provides VPN serves to my clients.
For the internet:
I have three networks adapters connected to different ISPs. Each one with different proxy and auth.
Eth0 connected to ISP1 with proxy proxy.ISP1.com with auth (user1/password1)
Eth1 connected to ISP2 with proxy proxy.ISP2.com with auth (user2/password2)
Eth2 connected to ISP3 with proxy proxy.ISP3.com with auth (user3/password3)
how I can transparent the proxies and load-balance the three connections ? So, My clients will connect to my server and won't have to enter the proxies or auth.
** I have read all the answers about Load balancing but I did not find anything about connections with proxies
