OK I don't have the real answer but it seems that NAT overload is on the
same IP address that you're trying to telnet to. That would be kind of
weird for the box to receive a telnet request from & to the same IP.
No flames but I'll just throw a suggestion to try (let me know if it works).
Try settting up an access-list for NONAT when going to that IP address.
That will leave the source address alone. And it looks like you've set up
an access-list to allow telnet to that interface already but double check
that.
I have to ask...why telnet to the outside interface from inside?
