We are planning to replace a few servers within our network, and I am trying to configure our Catalyst 6009 to use NAT to translate the target IP address to the IP addresses to the new servers. But I also need to be able to connect to the new servers directly.
I have installed a PC on vlan 24, the original server on vlan 50 (172.30.50.230) and the new server on vlan 51(172.30.51.230).
With the configuration shown below, when I telnet from the PC to the old server (172.30.50.230) I get connected to the new server (172.30.51.230) as expected.
The problem is that I cannot telnet directly into the new server (172.30.51.230), although ping and traceroute go through to the correct destination.
Is there another command line I need to enter to enable NAT to accomplish this or is there another method I could use instead?
I know I am missing something really simple, so if someone could let me know, that would be really helpful.
