Not sure what that means. If no UDP goes out, you did not start
the connection. IPsec always starts with IKE on udp port 500 and
depending on the nat-t standard/drafts used stays on udp port 500
or switches to udp port 4500, which may or may not get rewritten
by an upstream NAT device to appear to come from a "random high port".

The bootup logs of openswan tell you if nat-t is supported, enabled
and whether port-floating is enabled. If those are all enabled your
end is good to go.
Check firewall rules and NAT rules for interference.
