I've been trying to search online and the KB, but so far I can't find a clear answer: Is it considered unsafe to allow the source and destination WAN accelerators to communicate directly over the Internet on ports 6164/6165? Or is it necessary to route the traffic through an IPSEC tunnel? I ask because bandwidth across our SITE-TO-SITE tunnel to the target server is limited due to a Comcast issue. I can probably work around the issue by routing the traffic outside the tunnel. I understand that the traffic between WAN accelerators is encrypted, but I still don't want to do this if it significantly decreases security.
