General Routing

  • PKI CMPv2 (RFC 4210) client certificate enrollment does not properly work on SRX Series devices when using root-CA. PR1549954

  • Kernel might stop, with VM core files generated, and the system might reboot continuously after five child interfaces are added to the reth interface on one node. This might cause service impact. PR1551297

  • When the device is downgraded to earlier than Junos OS Release 21.1 and then upgraded again to Junos OS Release 21.1, the appiddb tables might not get populated properly and have 0 entries. For such cases, after upgrading, uninstall and reinstall signature package. PR1567199

Routing Policy and Firewall Filters

  • If a huge number of policies are configured on SRX Series devices and some policies are changed, the traffic that matches the changed policies might be dropped. PR1454907

VPNs

  • When multiple traffic selectors are configured on a particular VPN, the iked process checks for a maximum of one DPD probe that is sent to the peer for the configured DPD interval. The DPD probe is sent to the peer if traffic flows over even one of the tunnels for the given VPN object. PR1366585

  • In the output of the show security ipsec inactive-tunnels command, Tunnel Down Reason is not displayed as this functionality is not supported in Junos OS Release 18.2R2 and later. PR1383329

  • On SRX5400, SRX5600, and SRX5800 devices with an SPC3 card, a new behavior has been introduced that differs from the behavior on the older SPC2 card. The SRX Series device with AutoVPN configuration can now accept multiple IPsec tunnels from a peer device (with the same source IP address and port number) using different IKE IDs. PR1407356

  • On SRX5400, SRX5600, and SRX5800 devices, during in-service software upgrade (ISSU), the IPsec tunnels flap, causing a disruption of traffic. The IPsec tunnels recover automatically after the ISSU process is completed. PR1416334

  • Tunnel debugging configuration is not synchronized to the backup node. It needs to be configured again after RG0 failover. PR1450393

  • An IPsec policy must not have both ESP and AH proposals. The configuration will commit, but the IPsec traffic will not work. Do not configure an IPsec policy with proposals using both ESP and AH protocols. PR1552701

  • Do not configure two traffic selectors for the same peer under the same IPsec VPN with the same values. PR1554533
