I am setting up a router for a remote office with an Ethernet WIC on a 1721 going to a DSL modem. I have a pool of 6 usable Ip addresses. My question is, on my default route, do I use the Interface name? The Ethernet interface will have an IP of *.*.*.169 (first usable address)
ip route 0.0.0.0 0.0.0.0 Ethernet0
Or do I use another IP from the pool for the default route?
ip route 0.0.0.0 0.0.0.0 *.*.*.170
