Reverse telnet will work fine between 2501's. Just connect the AUX port of the 2501
you're reverse telneting from to the CON port of the 2501 you're reverse telneting to.
A loopback is often a good idea, but by no means necessary. You just need a valid IP
address that resolves to a working interface on the 2501 you're telneting from. There
are a few commands to contend with: for instance, it's sometimes helpful to clear the
line first. I found helpful references in the archives.
Good luck.

Thanks Erick,
I think my first problem here is that I have never tried to connect my two
2501 together by their CON ports - Do you need to make a loopback ip to do
that trick (with a rolled over cable ofcourse) ???
Thanks,
Ole

Let me take a hit at it... it's not one my favorite
terms...

Typically for 'reverse telnet' one configures a static
host table on the router pointing to a loopback IP
address on a certain port. The port # being the line #
on the router. So one can simply type r1, etc at
prompt then the router telnets to port 20xx and you
make your connection the device hanging off that line.
I think redirection is a better term actually but
that's me.
You don't need a host table (it makes things easier
for repeated use). You can simply do 'telnet
ip-of-router 20xx' from the router or any PC/etc to
get to devices hanging off the router.
Use 'show line' to get the line # and add 2000 to it
for the TCP port # mapped to that line.
