Currently I only have 1 Cisco 2600 router, which connects serially to a leased line device, with an Ethernet port that connects to my LAN.
Currently, I would like to add a new LAN segment (different network) to my LAN.
My idea is to get a new Cisco router that has 1 serial interface (connects to the old 2600 router ) and 2 Ethernet interfaces (connects to the old LAN segment and the new LAN segment respectively). However, my old router does not have anymore serial port.
What can I do to solve this? Any input is welcomed
