transparente mode to routed mode from SSH without loosing the connection

[lookingspicy]

Is it possible to change from transparente mode to routed mode from SSH without loosing the connection?

Firewall is hosted in a  datacenter and I do not have access to the console. Only ASDM or SSH  access is possible.

confirm that it is absolutely necessary to change to routed mode in order to configure Site-to-Site LANs?

Firewall ASA 5505

Hi,

if "site-2-site" LAN means VPN (IPsec static tunnel) then the answer is yes, you must switch to routed mode.

There is no VPN in transparent mode.

When switching to routed mode the asa will always reboot and come up with an empty config.

So I'm afraid you will either need some help on the side of the data center .

E.g. an engineer at the datacenter could connect to the asa physical console and permit you to use some desktop-sharing like team-viewer for an initial config: ip address, no shut, routing, rsa-keys and ssh-setup. I did it a couple of times recently and it worked prettty fine.

Otherwise you will need to be there physically.
