Is it possible to use a Cisco ASA 5505 for the following:


172.18.112.0/18(inside)----> 10.1.1.1(outside)-->internet--->10.1.1.2(outside)---->172.18.112.0/18(inside)


We want to extend our current network to a new building for a seasonal warehouse, but I am wondering if I can have that same network over there or if I need a new network over there completely.

thanks!

No, it is impossible!

I advise to use individual subnets, or use on SITE A the first /19 address and use the second /19 address on  SITE B

So you can't even setup a site to site vpn and use it in Transparent mode?

No, you not able to use same subnet for local and remota address... If you want it I advise to use L2tpV3

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

"impossible" Oh no!

You need to do  policyNAT of the traffic entering the vpn tunnel.

Of course, it is not the same network. You cannot do "bridging", but you can connect two networks with the same addressins by doing address translation.

So by doing address translation, I can have 172.18.112.0/20 on both my LAN here in the office and on our LAN in the remote warehouse?

There will be a DSL connection for the "outside" interface to set the vpn tunnel up with.

Yes, but you need to "fool" the hosts on each side that the other sides ip adddresses are something else.

We only have asa's for this project, I am sure I could come up with some older 2600's though. If I need to put a different subnet on the remote end, I can. My goal was to keep it though the same and just have the Vpn tunnel in between. The traffic going between is minimal, symbol rf scanning guns for product shipping.
