I guess you are looking for a http_resource solution. I think this is
the only way to resolve urls for use in access lists. Have a look to them.

Subject: [FW-1] NGX, dynamic object resolution problem



Hello there,

I have an NGX cluster (R60 HFA2 on SPLAT) in active/active load sharing
with ClusterXL and my problem is the following:

When trying to use dynamic objects (such as "microsoft.com" or
"www.google.com" for example), an 'accept & log' rule does not work.

I have found that an error message appears in the Tracker each time I
want to use the rule (i.e. when I initiate a connection through the fw)
:

[!]
origin : FWCLUNODE1
product : vpn-1 pro/express
interface : daemon
type : alert
information : "reason: failed to resolve dynamic object: 257"

I have therefore checked the my two cluster nodes (as well as the smart
centre) can resolve DNS names, which is the case (nslookup in expert
mode works well).

But a tcpdump on both nodes while attempting to connect (--> triggering
the "use" of the rule with a dynamic object) does not show anything ;
i.e. it is as if the enforcement module cluster nodes do not issue a DNS
query at all. [Nevertheless I don't know if CP's behaviour is really to
make a DNS query each time you use a rule with a dyn obj].

I've not found anything about this error message in the Secure
Knowledge...

Can anyone help on this issue?

Thanks
