We have a remote office that has a managed lease line and we have an ASA connected off this to create a site-to-site VPN to another office. However the company that runs this line is changing the public IP if the router and we will also have to change our ASAs info.
I have ask the guys to let me know before they pull the plug as I need to SSH onto the ASA and change the IP, but is this possible as I will change the IP and lose connection.
The VPN/ASA is a simple configuration, I only need to change 2 areas:
ip address 211.36.49.x 255.255.255.252
route outside 0.0.0.0 0.0.0.0 211.36.49.x 1
Any ideas on how I shoudl do this as I can't tavel there as I need to manage the other end at the HQ?
