RE: TCP/IP Question

[Charlie Prothero <Charlie.Prothero@xxxxxxxxxxxx>]

A *good* reason?  Maybe not.  Perhaps we're taking an overly simplistic view, but this is a College network, so we don't like unsecured protocols like FTP on the main network.  It also seems cleaner to give AS/400 jobs their own route to the file server such that they don't have to share a path with anyone else.  And both systems have extra Ethernet ports - so why not use them??? [last statement in jest!]

I have a call into IBM support for callback during business hours.  I'll report back what they say to the list...

Is there a good reason to have the adapters on different networks?
