| Subject: [PATCH 1/1] Reduce lifetime value to widely-compatible value |
| |
| Current proposed lifetime value (2147483 seconds, which equates to |
| MAXINT ms, or ~25 days) is rejected by Fortigate vpn devices because |
| "peer SA proposal does not match local policy". It seems default |
| policy for these devices constrains lifetime where similar VPN devices |
| don't. |
| |
| Reducing the lifetime from its current value to 28800 (exactly 8 hours) |
| causes it to start working with fortigate devices. |
