simple port forwarding

[FoxAll]

HI,

I'm new with Cisco configuration. I need to modify the config inside to add a port forwarding. So after enter the router with telnet, I type :

router-6#show configuration

router-6#config

router-6(config)#ip nat inside source static udp 10.47.104.2 12005 interface FastEthernet4 12005

router-6(config)#end

no error displayed. When I type:
router-6#show configuration

the new line just typed is not listed there?
Do I need to save or something?

thanks for your help

Do you have NAT enabled on the interfaces??

 

[FoxAll]

Yes NAT is enabled

by the way, I installed SDM to try to get the graphic interface.
When I start it, and try to connect to the IP, it ask me for my SSH username/password.
then, it ask me for my telnet username/password.

SDM tell me my telnet username/password is not valid.

But I can enter in the router using telnet with the username/password SDM reject?
it's strange ?

Ok,

I finally found my noob issue. I'm very surprise no one get it!?

router-6#show configuration
router-6#config
router-6(config)#ip nat inside source static udp 10.47.104.2 12005 interface FastEthernet4 12005
router-6(config)#end
router-6#[highlight #FCE94F]write mem[/highlight]

it works now

Thank you

You don't need to do wr mem for config statements to be added to the running config. wr mem is used to copy the contents of the running config to the startup config.
