We have a Sonicwall Pro 3060 that is transparently bridging traffic to the Internet and a VPN to another site. We are having connections being reset for no apparent reason. For instance, connecting Outlook to our Exchange server at the other site. Once every 2-3 minhutes on average, the connection is being reset, and Outlook looses connectivity. Through packet captures, I have confirmed that the Sonicwall is generating a reset packet, and sending it to the client, as if coming from the exchange server.
We have gone through everything we can think of, and have so far come up with nothing.
Any thoughts on why the sonicwall would be doing this?
