You must use a "straight" cable if you're connecting pc/router/etc. to a
hub/switch. And you definetely must use a "crossed-over" cable to connect a
pc/router to another pc/router and hub/switch to another hub/switch. Some
hubs/switches/routers may let you change manually the role of the port
(MDI-X or MDI) so it becomes "crossed" internally and you may use a
"straight" cable where the crossed one needed. Thus, on some devices it is
possible to change the port settings and to use a straight cable to connect
hub to hub and pc/router to router.

In your case,  2500 series router's ethernet port does not support this
feature and the solution to your problem is to use a crossed-over cable.
