Hi xt22, have you created the FILTER and NAT rules? Could print it for us?
One good shot is remove tunnel settings and add it again, but if there is more than 3 or 5 tunnels, this could be awful.
Maaan you are the best!!!That's it, try "loose".rp-filter: strict
Thanks, I will.Read this: viewtopic.php?f=2&t=102483&p=509070&hilit=port#p508981
and setup proper rules for both WANs.
