Potential Backward Incompatible Changes¶
Title |
Description |
|---|---|
Prevent same source and destination ip for peer tunnel |
System prevents defining two Peers with the same source and destination IPs. Using the same Peer with multiple labels is allowed |
LTE/WiFi statistics are queried periodically |
Changes the previous behavior of querying the devices on REST API request |
MTU Limit set to 9999 |
MTU is limited on device registration and connection to 9999 |
Validate LAN subnet overlaps with tunnel subnets |
Devices with LAN IP address that overlaps the tunnels subnets (10.100.X.Y) is not allowed |
Application permission updated in bearer access keys |
Requires to create a new access token for REST API |
Known Issues¶
Title |
Description |
|---|---|
During login, the username email is case sensitive |
The email used in account creation and login is case sensitive |
Slow websocket connection during heavy load |
During heavy traffic load, device connection to flexiManage may be impacted |
Tunnel loss and RTT during heavy load |
During heavy traffic load, loss and RTT calculation might represent biased values |
On unstable/slow connections some jobs may be presented as failed on timed out although succeeded |
In most of the cases, the jobs have succeeded and the system recovers itself by re-syncing the configuration |
Switching WiFi from 2.4Ghz to 5Ghz doesn’t restart DHCP server |
To restart the DHCP server for the WiFi interface, stop and start the flexiEdge router |
Inbound WAN ICMP with small identifier is dropped |
Inbound WAN ICMP with Identifier smaller or equal to 1024 may be dropped |
Configuration errors on device start |
Any configuration error such as no IP acquired by DHCP or low LTE signal may result with a failure. Errors that occurs after start are handled properly |
Overlapping subnets may cause an error in flexiEdge UI |
Configuring overlapping subnets on multiple interfaces in flexiEdge UI may cause an error. Once error detected, resetting the configuration will solve the Issues |
MSS clamping may not operate properly |
Some MSS clamping configuration may not operate properly. Modifying the tunnel MTU resolves the issue |
Remote Worker VPN client error |
Launching Remote Worker VPN client on MacOS will show an error on start, however it does not affect functionality. |
