I'm struggling to address an issue where as a policy I have internal virtualized/clustered servers on reserved DHCP addresses on a separate VLAN, and occasionally there is a situation where by the guests change hosts and end up on another VLAN (for whatever reason) or with a different IP address.
This isn't an issue for my internal users because all our communications works off DNS addresses, but I have a natted FTP server that whenever it changes IP/VLAN, i have to manually change the natted address on my ASA.
ex
static (inside,Outside) 100.100.100.101 192.168.100.39 netmask 255.255.255.255
would like to use a DNS address of ftp.domainname.com instead of the IP address so that if the inside IP changes I don't have to rewrite the static rule every time.
Is there any facility to do this with the ASA?
thanks
