   My first thought would be this is an ECN problem.  Indeed, without
changes I get connection refused as well.  With this rule it works:

iptables -t mangle -A POSTROUTING -o ${PUBINT} -p tcp -d 62.172.192.30 --match ecn --ecn-ip-ect 0 -j ECN --ecn-tcp-remove

Be aware that current released kernels don't have this working.  You'll
need a patch:
