Trouble connecting behind a Linksys

[joelbb]

I am running on a network behind a Linksys router and I cannot connect with Flash to another computer behind a Linksys router, both running NAT. I tried DMZ on my router, did not help. I tried various settings including binding the IP (which a friend said worked for him), did not help. Always get an error when it tries to open data connection for directory list - error 425. Any help would be appreciated.
