The only way that the access-list applied to the inbound interface ( non-vty
) blocked your telnet is if you were trying to telnet
To an address that was not the directly connected address ( loopback or far
side serial/ethernet )

If you were to telnet directly to the interface that the access-list was
applied to you WOULD get in. Only an access-class applied
To the VTY ports will stop that.

Thanks

I know it does.  I have, even fairly recently, locked myself out of a router
via an inbound access list applied to an interface,DOH:(  Try again and if
it doesn't work I would like to see the config.

  Are you sure the interface on which you applied the access list is the
interface you were telneting to/thru??
