John's blogSunday, 17 October 2010. Cisco Router behind a SOHO router settings. Please, anyone. Let me know if you find this useful! I've just completed my CCNA and I found this router configuation so useful that I wanted to set it in stone before I forgot it. It allows me to set up my Cisco Lab router (2620) to connect to the internet via my home router (Linksys 44000). The WAN interface fa 0/0 connects to one of your ISP router's LAN ports. Set up for NAT/DHCP Cisco Router siting. Behind a Linksys Router (WRN4000).
