We have a few customers who are using VPNs from remote branches utilizing DHCP from their ISPs, and we seem to run into this issue frequently: the IPSec VPN status for the remote branches shows that there is no connection, but the status is still green and we can communicate over the tunnel just fine. It seems to rotate between the branch sites that use DHCP and have to set up a respond only tunnel at HQ. All sites use the same PSK (I tried to set up different PSK as I thought that might be the issue and got an error indicating the PSK was invalid). Attached is an image demonstrating the issue. This has persisted from V7 to the newest version and is only mildly annoying but would like to find the cause for when customers ask. Turning off the VPN and turning it back on seems to resolve the issue temporarily.
