My office is having a LAN with 2 internet connections. (leased line and a ADSL connection)
Network is having a this configuration. http://www.janapriya.net/temp/current.gif
it seems like the one and only server is overloaded. And the load is not balanced. Again the ADSL router is not firewalled.
I have to propose a way to do this properly, this is the way currently I am thinking. http://www.janapriya.net/temp/proposed.gif
I would love to go for Linux. I have seen many applications supporting load balancing and firewalling. But I am curious whether it will be a pain to configure the linux firewall to allow the email exchange server. The problem is I can't get rid of Windows 2003 server. it has to be there.
Could any one enlighten me how to solve this problem.
Mainly I would like to configure our new LAN so that each PC will see only one gateway and one DNS Server.
