Hello,
I can confirm that my previously reported bug was fixed
(route disappears on IP address change).
However, I found another problem, possibly related, which can be
reproduced as follows with Strongswan 4.6.0:
- setup the test scenario as in ikev2/net2net-cert (ignoring winnetou)
- replace the ethernet link between moon and sun by a serial line,
run PPP on it with the IP addresses that were previously on ethernet
- start the IPsec tunnel -> route in table 220 is OK
- trigger PPP renegotiation -> route is gone
Charon log: see attachment.
Typescript (some output removed):
root@moon:~# pppd 192.168.0.1:192.168.0.2 passive noauth nodetach persist

root@sun:~# pppd noauth nodetach persist /dev/ttyS1
root@moon:~# ipsec up net-net
root@moon:~# ip route ls table 220

root@sun:~# ip route ls table 220
10.1.0.0/16 via 192.168.0.1 dev ppp0 proto static src 10.2.0.1
root@moon:~# killall -HUP pppd
# wait until IP addresses have been renegotiated
root@moon:~# ip route ls table 220
root@sun:~# ip route ls table 220
# the routes in table 220 are now gone
Regards,
Mirko
