IPSEC information

IPsec Information is part of a VPN tunnel. Go to your VPN tunnels and get a list of the settings there.

For Cisco RVxx and like machines, it is very simple.
For Juniper SSG machines, it is more complicated but you can save / print the configuration file and that makes it decent.
Larger scale Cisco boxes use a command language. I do not use these.

IPSec is a standards based protocol suite that many devices can employ. You can use it to establish a  VPN but also to secure communication between two computers on the same network or across the globe.

What exactly are you looking for?

i guess you just want to know the IPSec info or status of your router. what's the router's brand name and model number?

Cisco ASA 5512. Tks

You would need to save the Configuration File to a computer and then look through it for the settings you want

Thanks for responding.

Where should I look into should be in firewall

In the router configuration settings

Tks for response

Can I have an example of IPSec information?

Check this thread and see if that get you the info you need: https://supportforums.cisco.com/t5/firewalling/command-to-check-ipsec-tunnel-on-asa-5520/td-p/2110419

If you are learning VPN for the first time, it is, as was pointed in another thread, a big topic. You need to get some consulting assistance.

John, unfortunately the RV series is going to be way different than an ASA.

Yes, I know but the basic settings (maybe a different language and policy approach) are what a newcomer needs to understand in terms of basics. Very different even from Juniper which I also use, but grasping the basics of what is needed is important.
