Proxy Client forwarding internal request to ISA - 29.Sep.2011 10:24:45 AM

I am having an issue with a client that appears to ignore the proxy setup regarding "Internal" networks under certain situations. The Proxy servers internal network is 10.0.0.x and I have also listed 10.50.0.x as internal, and have checked to bypass the proxy server and directly access computers on that subnet. In fact, if I open up a web browser and access, nothing is logged on the proxy server and Wireshark has confirmed that it goes directly to that IP, not the ISA server. The problem is one of our Web apps (SynApps) tries to connect to and this is what is logged on the ISA server:

Failed Connection Attempt PROXYFW 9/29/2011 10:17:59 AM
Log type: Web Proxy (Forward)
Status: 12204 The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests.
Source: Internal (
Destination: (
Filter information: Req ID: 09e9d3a7; Compression: client=No, server=No, compress rate=0% decompress rate=0%
Protocol: SSL-tunnel

Additional information
Client agent:
Object source: Internet (Source is the Internet. Object was added to the cache.)
Cache info: 0x0

I do not understand why it is sending it to the ISA server ( when the request is to, an internal network. Also, why does it list the Object source as "Internet" when it obviously is "Internal"? Any help is apprectiated!!
