Hi
I have configured NAT on my cat6500 (IOS version).
However, it works with ping and web, but not ssh:
configuration assume as:
private subnet and machine is 10.10.10.20.
int vlan 10
ip address 10.10.10.10 255.255.255.0
ip nat inside
nat subnet:
int vlan 20
ip address 111.111.111.10 255.255.255.0
ip nat outsite
link to border router subnet, which default route come frim this link:
int vlan 30
ip address 10.30.30.10 255.255.255.0
ip nat outside
related nat command
ip nat inside source static 10.10.10.20 111.111.111.20 extendable
------
border router related subnet
int vlan 30
ip address 10.30.30.1 255.255.255.0
ip nat outside
now, from the machine, I can ping outside, but not telnet outside and ssh outside.
Could any one advice me if there is a special configuration required for ssh to work?
Any comments will be appreciated
Thanks in advance

Just to be clear, what are you trying to telnet/ssh to on the outside? Does the telnet/ssh work from any other internet location?

no, no any remote servers. what I mean remote, it is means outside of my domain, in internet.
