While still learning I am unable to find the name of the wan interface port on my Cisco 1841. According to SDM I need at least two interfaces to set up a NAT to provide Internet for my LAN hosts, I therefor assume I need to configure the WAN port and LAN port.
While the LAN port is titled FastEthernet0/0 in the configuration file, I cannot find the name of the WAN port in there. I have read the documentation available and searched around for it but unable to find any solution to my problem.
Any help is greatly appreciated.
