Hi,Johnson,
I have tried all the way you told me several days ago,But the Remote user
still can't connect to the center well, In fact, it works well in the IOS version 12.0(7)T, Why it doesn't work in the version 12.2 ? I think maybe the IOS software has been modified something about x.25 or protocol translation,But I can't find the change from the document. I think maybe is a software bug .Thank you for your help!
