I am from an IP background and I am trying to troubleshoot (with difficulty) an X25 connection.
I am using a 2621 with IOS 12.2 enterprise software. The 2621 is connected into a public X.25 cloud. I am trying to connect to a customer NUA / X25 address without success. The customer has an X.25 device.
I am translating IP packets from our network into X25 packets to be forwarded to the customer.
I have attached the following info:-
