http://serverfault.com – After starting fresh after a write erase and a reload on a cisco 871w. I cannot ping outside of the wan (fa4). I gave vlan1 (default) an ip because apparently the built in "4 port switch" is a layer 2 device so you cannot directly add IPs to the ports like on the 2800 series. Fa4 (wan port) is actually a layer3 port so I add the settings(ip, mask, speed, duplex) to fa4. there are no ACLs set up. I can ping another device connected to one of the ports and also the vlan from a connected computer. I can ping anything from inside the router other than the vlan. I cannot ping fa4 from a connect (HowTos)
