So the company I work for has a main and 3 satellite offices. All protected by Cyberoam units, and all interconnected with IPSEC VPN tunnels. We are upgrading and change our primary WAN provider here in the main office, and with that the external IP will change.
How involved is this to change that address with those tunnels in play? I assume, provided I could access the GUI's for them then I could just change the endpoint address and be done with it right? Or can I make this change remotely by changing the port on my firewall (the one all others connect to)?
I'm in a time crunch because the current wan providers contract expires on Dec 1, and we have the new 1GB line in and working already I just need to figure out the safest way to make the tunnel changes so I don;t have to drive 7 hours to hit all three of the sites.
Thanks!
