Automatic Interface IP Address Change

Unanswered Question

A customer of mine uses an application called webposition that queries search engines and returns results such as ranking. Their question was that if they had a block of public IP addresses... could we have an a PIX/ASA or another cisco appliance set a schedule to where the untrusted (WAN) interface could change it's public IP address every "x" amount of intervals such as once per week/day/etc.

I have no clue if this would be possible with an PIX 501 or ASA 5505. Any guidance would be greatly appreciated.

I figured the worst case scenario we could put the boxes running that application outside the firewall or in a DMZ and use netsh combined with a batch script to change the IP addresses.

No, you cannot automatically do it.

Your worse case scenario would have to work.
