I've had this problem before and am in a jam because I am on location and the agent's office and need this to work.
This office has 4 computers that are on a 10.0.1.1 network that is routed by a Cisco router (not sure of the model yet). Most agents like the one I am working on now don't opt for the firewall that I can install, but instead choose to use the Cisco VPN Client software that we got with the firewall at the main office.
This is used to connect them to an i5 (AS/400) that is in the corporate office with the address 192.168.0.2, it's public address is 188.8.131.52.
In the agents office, I installed the Client VPN software and Bossanova (the emulation program we use to print) on 1 on the PCs. The other 3 PCs are using the VPN software but use Client Access (IBM's emulation software) which we use for entering data, but not printing.
With that out of the way...I can start the VPN Client on the printing PC and obtain a connection. I can start the Bossanova and print like I should be able to do. On the other 3 PCs, I am UNABLE to connect the VPN Client at all. Even when the printing PC's VPN connection is off, I still can not get the other 3 PCs to even connect. The VPN Client states that "The remote pier is no longer responding" and the connection fails.
Why does this happen? One PC connects and the others will not? I don't know where to look for a solution...is it the agents DSL router in her office or is it a option on the firewall at our main office that needs to be configured.
Please pleeeeeeeeeeeeease help.
