10.10.10.101 is refusing to allow the inbound connection to UDP port
500, that's for the IKE exchange. That connection should be accepted by
the pluto daemon.
Two possible reasons -
- nothing is listening for connections. Since it works the other way,
presumably pluto is running. Check with 'netstat -anpu' to verify that
it's listening on the correct interface.
- more likely, you have iptables configured to block incoming
connections to that port. Make sure you're permitting udp port 500 in
your INPUT chain.
