IPSec/Strongswan updown errors in log

Virtual Private Networks
1

While digging around in the logs for something else, I stumbled across a number of messages like this:

Mar 16 08:09:51 myhost charon: 15[CHD] updown: iptables: Bad rule (does a matching rule exist in that chain?).
Mar 16 08:09:51 myhost charon: 15[CHD] updown: iptables: No chain/target/match by that name.

Any ideas as to what’s causing this? Bad configuration on my part, or should I open a bug?

I’m guessing that the problem lies somewhere in /usr/libexec/ipsec/_updown ?

Not really a problem, because the script tries to clear rules that are no longer there anyways.

Probably the firewall chain was flushed or something else.
