Does this squid ACL really blocks tor

[Arun SAG]

Hi,
I have found my network admin has added a squid ACL something like

acl numeric_IPs url_regex ^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+
http_access deny CONNECT numeric_IPs all

And now vidalia is not able connect to tor network (cant create circuits),
does this really blocks tor?

Thanks
