How do I solve this racoon error:"ERROR: unknown Informational exchange received."?
I successfully deployed a racoon on my Debian 7.0 droplet earlier today and at that time it works fine. I noticed a "routing loop" problem after I restarted racoon, and I ran :
```iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
After that the "routing loop" problem disappeared, but racoon showed another error: ERROR: unknown Informational exchange received. What should I do then? (IPv4 forwarding has been enabled.)Thank you.
