NAT configuration issue on ssh for cat6500

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.
