After many years with the same ISP, we are switching. We will not be able to use the same public IP address. For those of you who have had to completely review your firewall rules, is there any easy way or documentation on doing this?
My friend I ran into the exact same scenario, there is no other way other than conduct a thorough fw configuration isnpection, however, since you are chanching ISP which is mosutly your public IP block, glocal NAT, static NATs new defualt routes etc.. you can do the complete migration from PDM/ASDM, when chnaging these PDM automcatically updates rules, but good to have a backout plan or script for CLI as other resource of changing configuration . If you have any particular question Im sure someone will provide some hints.
:) Thanks, John, that would be great but the $ just aren't there. We're able to do the switch because it's basically just paying a different vendor. I'd love to swap out the 515E's but I guess that'll have to wait.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
