Crash

When I have a tunnel established, run iperf test on it, then run the client I get:

Key rotation failed: client/network: incorrect packet type
Key rotation failed: client/network: incorrect packet type
Key rotation failed: client/network: incorrect packet type

This is on openwrt, on a pretty low-end mips. Works fine without network test in backround.
