I have 1841 router, SDM is installed but FA 0/0 is connected to ISP modem, and FA 0/1 is connected to intern/w through a linksys switch, given ip address as per the interfaces

Interface                        IP-Address      OK? Method           Status                                Protocol

FastEthernet0/1            192.168.10.2    YES NVRAM             up                                    up

from my pc which is 192.168.10.44 i can ping 192.168.10.2 (fa 0/1 interface of router ) but cannot ping 4.2.2.2 or any internet, hence i wanted to add static DNS entries but i don't know the commands on cli, hence tried to add through SDM but "additional task" tab is disabled ...

Any ideas what to do next...

Thanks in advance.

hi,

If you want to make your router to use internet dns server or make it as DNS forwarder, you do it by "ip dns server" "ip name-server xxxx".

Then, you can add A record to IOS dns server with "ip host test x.x.x.x"

Your NAT config looks good so your PC should ping 4.2.2.2 fine.

would you try "ping 4.2.2.2 source f0/1" and type "sh ip nat trans" from router CLI?

On your pc have you put the correct gateway or mask in your ip config ?

If you can't ping L3 addresses, dns won't help you much.

For your additional task issue this is a problem with Java ( which version of jre have you got? try to downgrade to 1.6.0.3).

Don't forget to rate helpful posts.

To see 'additional task' in SDM, you need to downgrade your JVM.

According to http://www.cisco.com/en/US/docs/routers/access/cisco_router_and_security_device_manager/software/release/notes/SDMr25.html#wp35379

The following versions are supported:

*JRE 1.5_09
*JRE1.4.2_08
*JRE 1.5.0_06
*JRE 1.5.0_07
*JRE 1.6.0_02
*JRE 1.6.0_03

SDM is deprecated now, it's better to use CCP http://www.cisco.com/go/ccp
