Hi All,
I am trying to configure a cisco router 2620 with a serial interface, loopback interface and an ethernet interface. I have my loopback interface configured with our public addresses from our new ISP , and these public addresses are NATed into the ethernet interface ( which is configured with our existing public addresses ).
My problem is that I am only able to ping the NATed addresses. I am unable to access any other tcp or ip service on the NATed addresses. Here is my configuration.

interface Loopback0
ip address 216.48.10.65 255.255.255.224 secondary
ip address 216.48.10.1 255.255.255.192
ip access-group 106 in
ip nat outside
no ip split-horizon

interface Ethernet0/0
ip address 65.165.148.251 255.255.255.128
ip nat inside

!
end

So as an example,
If on the router I do telnet 216.48.10.5 , I get connection timed out, while ping works.
The Default Gateway on the Machine is set to 65.165.148.251 (Ethernet Interface's Address).

Please Help.

Thanks,
