Configure Flash Player ALONE to connect via an existing, working SOCKS SSH tunnel?

    Before I start please note a similar thread exists on the Software and Development > Development forum although it goes into less networking related detail why my current workaround is infeasible. The reason I posted that version there is to see if there is any solution within Flash Player itself.

    I use Flash with Portable Firefox from a USB pen drive. It appears to work fine with using my SSH tunnel with virtually all Facebook apps I have tested it on but when I try to use Facebook's Zynga Texas HoldEm Poker it returns the error:
    Your firewall may be blocking access to port 9339.
    From this and as suggested to me on this very forum it appears that Flash ignores the connection settings configured in Firefox Portable and attempts to connect directly.

    N.B. - the tunnel itself is definitely working fine and accommodates all other traffic, I have checked my IP online to confirm this.

    I am able to work around this by using Sockscap, a freeware lightweight SOCKS wrapper which wraps all of Firefox Portable in the proxy 127.0.0.1:5555 which is a SOCKS SSH tunnel configured with PuTTY connecting to OpenSSH running at home. The problem with this method is I use the same browser to connect to local systems in different tabs on the same session, and when Firefox Portable returns my home IP to said systems access is denied.

    I am researching a way to only SOCKS wrap TCP/9339, 74.114.14.41 the IP the connection needs to be established with, *.facebook.com, *zynga.com or Flash itself in its entirety, which is why I am here.

    If relevant my Flash Player install is portable? That is, I manually installed NPSWF32.dll and flashplayer.xpt to /Firefox Portable/Data/plugins/.

    My options within Sockscap:

    The method below opens TCP/9339 and I can use the web and Texas HoldEm Poker as if I am at home but denies access to local systems.

    SOCKS wrapping all of Firefox Portable in the proxy 127.0.0.1:5555 and configuring the following direct addresses (these are not the actual IPs or ports):

    192.168.1.10 to access http://192.168.1.10:1234/blah/blahblah.jsp - this works.

    abc.domain.tld to access http://abc.domain.tld:1235/ - this works also.

    the ip which is returned by cmd > nslookup for blah1.blah2.blah3.blah4.domain.tld to access http://blah1.blah2.blah3.blah4.domain.tld/cgi-blah/blahblah.cgi - this does not work.

    When I use Firefox unsocksified some of the systems I need to use onsite will work with Firefox set to use no proxy although they are very slow whereas when then on site proxy is enabled all of them work.

    Ideally everything would go through either the on site proxy to access the local systems and my remote proxy for personal use apart from Flash Player which needs to be SOCKS wrapped down the remote proxy. This would allow me to access everything via Firefox, the local systems and private use websites as normal in addition to Flash Player with TCP/9339 open.

    To clarify I know it's possible to easily use two proxies at the same time in Firefox because I have been doing so with an addon, one on site, one an SSH tunnel going remote but what I need is that AND just Flash Player SOCKS wrapped? Is this possible?

    If a VPN would resolve this, I only want to configure it after I have exhausted all possibilities of using SOCKS wrapping and the SOCKS SSH tunnel.

    Any suggestions?

    The smallest bit of help would be greatly appreciated.
