weird IP problem

Hi,

We have two routers connect to a layer3 switch. We've assigned 255.255.255.240 subnet to interfaces which connects routers and layer3 switch as follow.

Router1-eth0 Router2-eth0

*.193/28 *.209/28

- -

- -

- -

*.194/28 *.210/28

Layer3 switch

The problem is that it seems like layer3 switch is translating outside ips(connecting to port80/21) to IPs within subnet that aren't used by interfaces.

For example,

Let say, the client has IP of 24.24.24.24. The client IP will change to *.214 or any unused IP if he connects to port 80/21 on our web server

I don't understand why is doing.. :(

Can anyone shed a light on this??

Thank you

Re: weird IP problem

Problem solved...

It wasn't really translating IP. Our IDS system rule cause the problem.

Thank you for you time...
