Most DNS servers support the delegation of subdomain authority.

You have two options to delegate a sub domain to the GSS.

Direct delegation of A record, or delegate using CNAME.

Refer to pages 9-10 of the attached best practice guide.

Hi,

I am new to GSS. I would appreciate if some can help me with the deisgn. I want to know if I need to put the GSS inline after the inernet facing firewall and befor the ACE module. OR use it as one arm mode. Trying to figure out the best fit in the design.

FWSM1 >>> GSS >>> ACE

or

just put the GSS as one arm mode between the FWSM1 >>> ACE

Thanks in advance,

Hi Nav,

We do not have a set guideline on placement.  We offer some considerations, for example on how to assure proper communication between GSS, if you have multiple units in a deployment. For guidance we do have, please refer to the 'GSS deployment topology'  section in the 'best practice' doc which I previously posted to this thread, and also the product configuration guide which you can find at this link:

Great document "pefrench", thanks for sharing.

I've been delegating subdomains to GSS using CNAME's for several years, but I really need to make the GSS authoritative for an entire domain.

Do you have any links or documents that explains this configuration?

Steve
