FreeS/WAN sent its first packet, attempting to initiate a negotiation, but
never received a response.

Your static host received that first packet...

... but it's attempt to respond was blocked, most likely by your firewall.
Check your iptables rules; you are allowing IKE traffic in, but you don't seem
to be allowing responses.
