ASA 5520 9.1(7)32 & ASDM 7.8(1) basic config help

Level 1

I've been fighing this all day and im going in circles.  I have a block of static ip addresses "xxx.yyy.56.104/29.  i dont know if it matters but im using a single subinterface for everything other than asdm.  if it is important that can change.  the ultimate goal that im trying to accomplish is i would like to map .105-109 to indvidual private subnets ie. 10.10.105-109.0/24.  at this point i would be happy to get boring old nat/pat working.  then start working from there.  im i doing something wrong?

Hello,

 

a basic NAT with pool configuration would look like below. You need one pool for each address, create a network object for each subnet, and the NAT this subnet to the appropriate pool:

 

ASA5520(config)# object network NAT_POOL_105
ASA5520(config-network-object)# range xxx.yyy.56.105 xxx.yyy.56.105
!
ASA5520(config)# object network INSIDE_NET_105
ASA5520(config-network-object)# subnet 10.10.105.0 255.255.255.0
ASA5520(config-network-object)# nat (inside,outside) dynamic NAT_POOL_105
!
ASA5520(config)# object network NAT_POOL_106
ASA5520(config-network-object)# range xxx.yyy.56.106 xxx.yyy.56.106
!
ASA5520(config)# object network INSIDE_NET_106
ASA5520(config-network-object)# subnet 10.10.106.0 255.255.255.0
ASA5520(config-network-object)# nat (inside,outside) dynamic NAT_POOL_106
!
ASA5520(config)# object network NAT_POOL_107
ASA5520(config-network-object)# range xxx.yyy.56.107 xxx.yyy.56.107
!
ASA5520(config)# object network INSIDE_NET_107
ASA5520(config-network-object)# subnet 10.10.107.0 255.255.255.0
ASA5520(config-network-object)# nat (inside,outside) dynamic NAT_POOL_107
!
ASA5520(config)# object network NAT_POOL_108
ASA5520(config-network-object)# range xxx.yyy.56.108 xxx.yyy.56.108
!
ASA5520(config)# object network INSIDE_NET_108
ASA5520(config-network-object)# subnet 10.10.108.0 255.255.255.0
ASA5520(config-network-object)# nat (inside,outside) dynamic NAT_POOL_108
!
ASA5520(config)# object network NAT_POOL_109
ASA5520(config-network-object)# range xxx.yyy.56.109 xxx.yyy.56.109
!
ASA5520(config)# object network INSIDE_NET_109
ASA5520(config-network-object)# subnet 10.10.109.0 255.255.255.0
ASA5520(config-network-object)# nat (inside,outside) dynamic NAT_POOL_109
