Pesky network security appliance blocking projects

Our company's network security appliance, a SonicWall firewall, has started blocking and reporting what I assume are false positives for malware. First, is it common for small company firewalls to have false hits on boinc projects and is there anything that can be done to avoid it other than convincing the admin it's a false positive? Here's what is being reports on POEM...

Well, I don't recall ever hearing that POEM was tagged as a false alarm. Something like BitcoinUtopia I'd almost expect, but POEM? Nope.

Are you sure the firewall has the latest signature database? Maybe it was an erroneous update and has since been corrected?

Another possible way to approach it may be to see if it blocks it if the request is "repackaged" by using a Proxy server. I have 2 proxies defined for my BOINC hosts and that did help on some problems I was seeing with our IPS device falsely tagging some packets. Additionally it may even help if you can set that proxy up outside of the work network, although that adds a level of complexity I haven't yet worked through myself.

But surprisingly, he has agreed to allow those pass through.

So who did you piss off in the IT department?

All of them!
