+ 0 Votes thoughts Lwood 6 years ago Assuming the ASA is facing the internet and the 871 is behind the ASA - your default gateway for all traffic leaving the 871W would be the ASA. I would setup a /30 address between the two devices - ASA 192.168.0.2/30 - 871 192.168.0.3/30. Then on the 871 you would have a new default route pointing to the interface connecting to the ASA inteface. Might look like this "ip route 0.0.0.0 0.0.0.0 fa4" Another though...I don't know alot about the ASA but if it has switching functionality then you would take the 870 and dumb it down to just a switch with vlans associated to what you setup on the ASA. Since the 870 will let you bridge your WLAN traffic you could get your 870wlan and all ethernet traffic on the same vlan. It's complex what your trying to do - good luck. You can always open up a tac to cisco for advice.
