Help using session firewall option.

Hello,

While using 'firewall' setting in a 'session' the connection fails to connect.



Selecting a 'session' HostA..C session will login to the firewall and connect the session direct to the client.

Code:
[SecureCRT] --> [SSHD Jump] ------> ClientA
                              \---> ClientA
                              \---> ClientB
                              \---> ClientC
What has been successful:
Creating the SSHD Jump session:
[LOCAL] : SEND[0]: SSH_MSG_CHANNEL_OPEN('session')
[LOCAL] : SEND[0]: Pty Request (rows: 70, cols: 175)
[LOCAL] : RECV[0]: pty request succeeded
[LOCAL] : SEND[0]: agent forwarding request
[LOCAL] : RECV[0]: agent request succeeded
[LOCAL] : SEND[0]: exec request: null -tenant username -host hostname
[LOCAL] : RECV[0]: exec request succeeded
SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.3


What has been unsuccessful:
From the above you can see the current firewall is directly connected to the end client session yet the client session does not reply.

It seems that sCRT is trying to be fancy.
- sCRT modifies the first firewall session
- Adding: [LOCAL] : FIREWALL : Starting port forward from 127.0.0.1 on local 127.0.0.1:59340 to remote sv-vpn:22
- Issue: [LOCAL] : Changing state from STATE_NOT_CONNECTED to STATE_CLOSED



This is highly complex in dealing with how the sessions are reused.
Is it possible to reuse the firewall port/session for the client/session communication?


Please do ask questions if i have been unclear, I would be happy to provide more details / logs ...

Thank you.
Derek
