Problems with SYN when using XML through Web Proxy

[Guest]

We are currently trialing the firewall and all is working well, except for our XML.

We XML data out through HTTPS, and then sleep the script for 30 seconds before checking for a response. However when we recieve the response it is blocked by the proxy, and it makes a log with something along the lines of "SYN NOT PRESENT" (i can't remember exactley what the message says but its to that effect.

Is there a way to disable the SYN check on incoming connections? Or even a SYN cookie option like in smoothwall express?

Thanks in advance,

Joe
