Hello everybody,

i have read some documents about cisco Load balance features (SLB) and it looks good, but unfortunately i can't use it on my 2811 router. So i have to do something to balance my outside to inside traffic. Here is what i mean. Let's say that we have two servers. Server A and server B. They both are connected to router 1. The goal to achieve is following: When someone tries to connect ip X (which is address located behind router 1, or on router 1), then the router should translate the connection to router X, and send it to ServerA or ServerB in round robin basis. I Read it in Cisco.com webside, but it doesn't work.

Here is my configuration:

ip nat pool DESTINATION x.x.x.9 x.x.x.10 netmask 255.255.255.252 type rotary

ip nat outside source list TEST pool DESTINATION

ip access-list standard TEST

permit x.y.z.1

ar1.sof3#show ip nat statistics

Total active translations: 10 (0 static, 10 dynamic; 9 extended)

Outside interfaces:

FastEthernet0/1.225

Inside interfaces:

FastEthernet0/0.9

Hits: 1465 Misses: 8

CEF Translated packets: 37, CEF Punted packets: 719

Expired translations: 424

Dynamic mappings:

-- Outside Source

[Id: 1] access-list TEST pool DESTINATION refcount 10

pool DESTINATION: netmask 255.255.255.252

start x.x.x.9 end x.x.x.10

type rotary, total addresses 131, allocated 0 (0%), misses 0

Queued Packets: 0

I have a "ip nat inside" on outside interface, and "ip nat outside" over the inside interface (path to the servers).

The end result is that all TCP requests which are send to address X are getting translated ONLY to ip x.x.x.9. The ip x.x.x.10 never gets one.

Any suggestions? Is there something wrong with my configuration?

Thank you in advance!
