Today, my ASA5510 outside interface have the ISP IP (from DHCP aaa.bbb.50.144).
I do use NAT to access a web server in a DMZ ("static (dmz,outside) interface 172.16.1.80 netmask 255.255.255.255") from the outside interface.
Tomorrow, we will have our own IP x.y.z.36/30, so x.y.z.37 for the ISP facility and x.y.z.38 for our ASA5510.
With also a set of public addresses j.k.l.64/27 to access our web servers on specific addresses like j.k.l.65 > 172.16.a.a, like j.k.l.66 > 172.16.a.b, bla bla bla
My questions are:
A. Will the outside interface have the address x.y.z.38 or one of the j.k.l.64/27 ?
B. If my outside interface have the address x.y.z.38, do i have only to do NAT to tranlate j.k.l.65 > 172.16.a.a, like j.k.l.66 > 172.16.a.b, etc ... to accesse web servers ?
x.y.z.36/30 and j.k.l.64/27 are from different ip classes.
Hope to make myself clear,
Thank you for your recommandation,
