The ASA 5505 comes with a default ip of 192.168.1.1. That is fine for a starting point, but we have expensive software authorized for a subnet of 10, so I must change the firewall to match.
The problem appears to be that it processes the changes in sequece. So when I change the Vlan1 IP to a subnet of 10, it objects because that does not match the dhcp subnet that is still 1. And when I change the dhcp subnet to 10, it obhects because the Vlan1 subnet is still 1 due to its previous objection.
So I appear to be caught in a chicken and egg situation. As you can see from this output, I have them both set to 10, and after the settup is done, it processes it all, in sequence, objecting to changes that don't match the current settup before even looking at the next settup changes:
[OK] Interface vlan1
[ERROR] ip address 192.168.10.12 255.255.255.0
Interface address is not on same subnet as DHCP pool
ip address command failed
[ERROR] dhcpd address 192.168.10.13-192.168.10.254 inside
Address range subnet 192.168.10.13 or 192.168.10.254 is not the same as inside interface subnet 192.168.1.1
[OK] write memory
Anyone have an idea how to proceed ?
