After implementing HA Active/Active, we left S2S VPN tunnels alone.  Ultimately no changes to IKE Gateways.  The S2S terminate to a /30 address that is statically routed from the ISP to ethernet1/12 on the active-primary.  Tunnel interfaces and their routes are identical on both primary and secondary, IKE Gateways are NOT synced as this is just an IP assigned to the 1/12 interface on the primary side.  OSPF on the internal LAN side, HOWEVER, supplied static routes for the remote sites to only route to primary device.  Secondary should never be session owner. Session Owner = First Packet Session Setup = ip-modulo Phase 1 and Phase 2 seem to come up fine.  Communication is established and devices can talk fine.  However, the key lifetime is set for 2 hours.  Throughout the day, the remote side will stop responding at key expiration.  It appears that a new negotiation is started and completed, however for the two hour key time the VPN tunnels will not pass traffic.  This doesn't happen every time it negotiates, and I can seem to locate a pattern.  The best lead that I have right now is that the return traffic from the remote side is being discarded due to the flow being in a discard state.  I can also see where the 'decap packets' in the vpn flow will not increment.  I've looked through the ike debug log and don't really see anything going on there during this state of limbo.  Phase 1 appears to be up, phase 2 SAs seem to be up, but for some reason the firewall is rejecting these return packets and I cannot determine why.  If can clear phase 1, and the flows and it will pick right back up.  Other option is to just wait for Phase 1 to timeout and re-key.  These devices were working fine prior to HA to the best of my knowledge. Any help would be greatly appreciated! == Apr 07 09:33:26 == Packet received at ha_ingress stage Packet info: len 1532 port 49 interface 49 vsys 1   wqe index 228383 packet 0x0x8000000416f718e0 Packet decoded dump: L2:     00:1b:17:3c:21:31->00:1b:17:c8:6f:31, type 0x7261 L3 binary dump: 40 bytes 00000000: 80 02 00 1b 00 1b 17 3c  21 1b 00 16 4d 6e a6 8c    .......< !...Mn.. 00000010: 08 00 45 00 05 dc c8 d9  40 00 36 06 ff 43 c7 1b    ..E..... @.6..C.. 00000020: 4e b8 41 29 20 02 00 50                             N.A) ..P ...skipping...
