Sometimes web servers use several interfaces for "redundancy" reasons and then they simply assign an IP address from the same subnet (Windows does not prevent that)! This usually works on a local network without security devices (firewall, load-balancers, etc.), but it can cause problems if those devices are in place. There is no workaround applicable from the SonicWall because the 3-way handshake must be established in the right way for security reasons. a SYN-ACK is sent, but the server is dual homed (multiple interfaces in the same subnet) and it sends the response out a different interface.Analyzing packet capture, we see that the TCP 3-Way Handshake is not correctly established: the "SYN, ACK" for the "SYN" packet is missing from the handshake.īypassing the SonicWall, the website is always reachable.
