I have in my network three routers that have this setup. R1<--->R2<--->R3. Connection between R1 and R2 is serial whilst that between R2 and R3 is ethernet.I have an X25 client connected to R1 as ^104 and from R1 and R2,the client is reachable when I do "pad 104".However,when I try to access thesame client from R3 using "pad 104",I get the message " % Connection refused by remote host"
Can anybody tell me what needs to be done in order to get R3 access the X25 client coonected to R1.

Hi, you would need to X.25 over ethernet or X.25 over IP (XOT) to do pad natively from R3. Since it kind of awkward to do this, perhaps you are better configuring protocol translation (either 1 or 2 steps method) so that telnet from R3 would become pad on r1.
Hope this helps, please rate post if it does!

thanks a lot for responding to my problem.
Could you please have a look at my configs and make suggestions. Also,could you possibly show me how to configure the protocol translation as you suggested.

Hi,
you only can check you config, based of it works or not. However I do not quite understand the x25 routes on R3.
