Cisco ASA VPN DHCP through Cisco ASA Firewall.

[raun.williams]

Hello all!

Quick question.  I have an ASA5520 (8.2) acting as a VPN server with the correct configuration to request a DCHP address on behalf the VPN Client.  However, This ASAVPN is connected to a vpn-dmz on my other ASA5520 (8.0) that is our main firewall.  I can see the request coming through the DMZ and to the inside interface of the ASAFIREWALL and out.  The DHCP Server responds and sends it back to x.x.x.0.   I did not originally have dhcp relay setup on the ASAFIREWALL as I had upd 67 open, thinking it would just allow it back through with out issue.  Any idea how to go about getting this to work correctly?                  

Thanks,

Raun

Hey Julio

Thanks for the response.  I was actually able to get my situation working with out any static translations.  However, that document is very useful for ANOTHER project in the works, so correct answer anyways!
