We have purchased a Cisco 2901 Router, I need to configure Internet Sharing and Port Forwarding on this device. My question is
1. Default route is enough to configure the internet sharing or I need to configure NAT Overload along with Default Route.
2. Beside that I need to configure/enable Port Forwarding option on public IP so that external clients can communicate to Application Server located in LAN, does internet sharing with NAT Overload and Port forwarding work together.
