RE: NAT with redundancy

Good morning,

In its simplest form, ios nat without the slb code that only appears in older code trains can be a poor man's load balancer. This is along the lines of what you are looking for...

ip nat pool webmailservers prefix-length 24 type rotary
 address 192.168.1.50 192.168.1.50
 address 192.168.1.52 192.168.1.52

ip nat inside destination list webmailonatt pool webmailservers

! Note this ACL contains the 1 public IP inbound traffic comes to

ip access-list standard webmailonatt
 permit 12.207.43.148

Subject: NAT with redundancy

Hi there ,
              It is a requirement to have one outside global ip to access a
internal server but if the internal server is down , have to translate the
same outside global ip to another internal (secondary) server.

Can any one help me , how could it be achievable using NAT.

Regards,
Anbu
