PAT overload query

[Raja_D]

 Hi,

Its pat overload query, can someone clarify

Can't it be possible that we can be able to use the ip :192.168.50.24 from Network   192.168.50.24/29 for pat overload.

Ex:

Ip access-list standard 1
10 permit 10.51.12.11
20 permit 10.51.12.12
30 permit 10.51.12.13
40 permit 10.51.12.14

Ip nat pool LAB 192.168.50.24 192.168.50.24 netmask 255.255.255.248

Ip nat inside source-list 1 pool LAB overload

Please clarify this as I have recently faced an issue in my network setup while deploying patting as I am able to pat all the 4 server's which are part of acl 1 to a pat ip 192.168.50.28 with netmask 255.255.255.248 but could not do with 192.168.50.24 , where if I go with pat with 192.168.50.24 I am able to get pat translation done for only 1 server but not for the rest.

What could be the reason ?

IP address 192.168.50.24/29 is the subnet ID. Your host range is 192.168.50.25 - 192.168.50.30, so any of those host addresses can be used for PAT overloading.

Hello

IF you wanting to use load balance one nattted virtual address and map that to multiple private servers addresses?

Nat LB Example:
ip access-list 1 permit 10.51.12.15
Ip nat pool LAB 10.51.12.1 10.51.12.14 prefix-length 24 type rotary
ip nat inside destination list 1 pool LAB

Nat matching outside address to inside address
ip access-list 1 permit 10.51.12.11
ip access-list 1 permit 10.51.12.12
ip access-list 1 permit 10.51.12.13
ip access-list 1 permit 10.51.12.14

ip nat pool LAB 192.168.50.11 192.168.50.14 prefix-length 29 type match-host
ip nat inside source list 1 pool LAB
