I am connecting the inside interface to an upstream switch and therefore will need to assign a static IP address to the inside address as I did below:
#sho int ip brief
Vlan1 220.127.116.11 YES manual up up
I will also use this to manage the ASA. I am having a problem with the network configuration of the inside interface as I can't ping the gateway and/or the in IP of the inside interface.
Do I need to add any routes?
Am I forgetting some other steps?
Yes that's correct, if the host is not in the same network as the ASA inside interface, then you would definitely need a route for the next hop through which that network is reachable.
Do you have route to 18.104.22.168 from the management PC? Check if Vlan may be the issue(inter vlan communication in case of different vlan).
Also, ASA need to know how to get back to your management PC subnet (you need to add Static route or use IGP)
