RE: Connect to remote system DRDA port

There's either a firewall or an exit point registered that is blocking the back-ports or response.

I've run into security packages that register programs on the drda exit points. The programs check user identity and authentication. If you aren't granted access within that security package, the program blocks the response and you'll get a timeout message like the one you see.

Remote system on V7R1. Not sure of PTF level.
Local PC running Windows XP Pro latest service pack.

When connecting to other systems using VPN and running release 5.4 to 7.1 I have no problem.

All,
I have a remote IBM i system that I connect to via Client Access
5250 emulation.
There is no VPN or firewall on the remote system.

All Host Servers are started at the client.
NETSTAT shows:
Remote Remote Local

* * ddm 124:20:46 Listen
* * 447 124:20:46 Listen


In i Nav, verify connection, I receive the following error:
CWBCO1022 - Remote Port 446 will be used
CWBCO1003 - Sockets error, function connect() returned 10060
CWBCO1048 - A timeout occured attemtpting to connect to the iseries.

The remote site is running R7.1.
DRDA server (port 446) is active on the remote site.

Why can I not connect?
There is no firewall and no vpn.

I use Client Access (whatever the latest nom du jur is) to connect

directly

to the client.
I am using a public IP address: 124.xxx.xxx.xxx to connect.

I can transfer files from the remote system to my PC using client
access file transfer.

I want to be able to use RDP at the remote site, but need the DRDA

server

connection.

Thanks,
