Is it possible for an ASA to proxy-arp for an IP, and forward requests for that IP to a different destination?
Scenario: We removed our internal DNS server to a completely different facility. The network is to be completely dismantled. We just found out we need to keep the network up for one more week, but the DNS server is now gone. I'd like the ASA to answer requests for the old DNS server IP, but them forward them on to our ISP's DNS server. Failing this, I'll have to have the client change all their DNS settings to the ISP's DNS server and allow the traffic through the ASA. Thanks for any assistance.
