I have a stange issues with FWSM, find the attached diagram

I'm trying to connect to remote site server on a specific IP from my server. when i do telnet on port 80 from my windows server it works fine but for port 443,1919 it doesnt works, when i bypass the FWSM all port open without any issues.

Strange when i start packet captures on FWSM and at the same time initiating a telnet 10.27.27.27 80 on windows server i dont see the return traffic in the capture by the destiantion server but the connection completes in windows. the same when i do for the telnet 10.27.27.27 443 it fails below are the capture logs for 443 and logs for port 80.
