I have a problem with routing. I have a situation where our office is connected via a VPN wan to several branches but we have remote users who would like to connect to a particular web server to access a web based application. I cannot put this server on a public interface. We have a secondary DSL connection which I would like to utilize for our remote users to use to get to this server bypassing our CISCO VPN router.
DSL has static public IP address 220.127.116.11 and it is connected to a soho router (with LAN IP address of 192.168.2.1) with port forwarding enabled which re-direct port 80 to the internal web server (192.168.2.29). DHCP is disabled on the SOHO router since there is already a dhcp server running.
The webserver is part of an internal VLAN and is connected via VPN and MPLS to other branches. I can get to the webserver from within the internal network but when I try to access it via the DSL connection it does not work. Default route on the webserver is the ip address of the VLAN (192.168.1.150) and not the ip address of the DSL router (192.168.2.1) because it needs to be accessible from the VLAN also.
My problem is configuring the routing so that traffic coming in from the DSL side is returned via that route and traffic coming from the internal network stays within the internal network (VLAN).
Do I need two network cards and if I do how should I configure them to accomplish this ???
Any help would be greatly appreciated.
