TCP Checksum error

Daniel O'Brien-3

Has anyone else experienced anything like the following:



This is a screenshot of the QuickFix engine trying to establish a connection (I am the initiator) with a sell side fix engine.  Without any fix messages being exchanged I am rejected the connection because my TCP stack thinks we have an incorrect TCP checksum from a packet received from the remote fix engine and so the connection doesn’t even get made.


Any thoughts/ideas much appreciated.
