I have a question. Users connect to ipsec VPN terminating on my ASA. Downstream from the ASA is another firewall and downstream of that is my DNS server. The admin of the firewall in the "middle" will not allow the IP's in the Pool assigned to the VPN users access through to perform DNS queries. If he allows the ASA access to perform DNS can I use the ASA as a DNS proxy\relay for the VPN clients?
If not any other ideas other than getting the firewall admin to open up his firewall.
