ASA 5520 DNS re

[award4glow]

I am trying to setup our ASA5520 V7.0 to resolve DNS.  multi context mode. We have names defined but also have have set dns servers in the config and it seems that the server does not recognize that it needs to be using external dns provider.  

hostname aw

domain-name award.com

dns domain-lookup outside

dns name-server 4.2.2.2

aw/vlan20(config)# ping www.hp.com
                                       ^
ERROR: % Invalid input detected at '^' marker.

Hi,

If i understand it correctly , I see that you are using the ASA code:- 7.0

This does not have the "dns server-group" or the name server command available.

I would request you to verify the configuration on the ASA device.

Refer:-

Thanks and Regards,

I have verified the software version is 7.0(4) and the commands are for dns server-group are not valid.  It does not even seem to recognize that it should be using DNS instead of names.  When i issue the ping command it gives invalid input error.

hi,

i think he's referring to device version and not ASA code.

try to configure below:

dns domain-lookup outside

DNS server-group DefaultDNS
    name-server 4.2.2.2
    name-server 8.8.8.8
    domain-name award.com
