Cannot make a connection to the AS/400

Either
- wrong IP address for the AS/400
- The Telnet server is not running on the AS/400
- A firewall stopping access on port 23.
- The iPhone/iPod is not on the same network as the AS/400


- How to connect to an AS/400 from the Internet (EDGE)

To allow a connection with the iPhone on the EDGE network or another wifi network, maybe at your local Cafe, you must configure the router/firewall protecting your office network to allow traffic on port 23 or 992 if using SSL. This could be a security risk! Read the router manual for advice.
 
An example:
I have a router at my office, which connect to the Internet. It has IP address 88.1.2.44 on the Internet. The router has a fixed IP address on the Internet, if your internet provider (ISP) gives a  dynamic address, a solution could be to use a service as NO-IP

Our Office AS/400 has a fixed IP address on the local network (wifi) at 192.168.2.2
 
In the router firewall configuration I have configured, if it receives data on port 23 (or 992 if SSL is enabled in TN5250), forward it to 192.168.2.2.
When on the EDGE network with the iPhone, I will in TN5250 as AS/400 IP address write
  • 88.1.2.44 , and as port 23 (Not the IP address for the AS/400!)


- Only US EBCDIC codepage works


There is a bug in v 1.0. Only EBCDIC codepage 037 can be used. This problem will be solved in v 1.1


- Program terminates in the connect dialog


In TN5250 v 1.0, there is a bug, if the keyboard is shown in the Connect dialog, and the user press "Host List" in the title bar. Close the keyboard with [Done] key in the keyboard, before using "Host List" . Will be solved in v 1.1
