ACE30-MOD-k9 in bridge mode. Individual server in the same vlan of Real Servers not reacheable.

 

I configured ACE30-MOD-K9 in bridge mode and I configured a server farm with his real servers. The traffic passes and is balanced correctly between all RSERVER. But I can not contact a server that is on the same vlan of the serverpharm but doesn't belong at this serverfarm.

I Thought that the traffic directed to this "spare" server shouldn't  be balanced but the bridge should permit traffic to pass. (trasperent mode) Is it correct ?

What does ACE in bridge mode with traffic directed to servers that do not belong to any server farm but are present on the same VLAN (same bridge group)?

 

In rispect at the following configuration 10.10.10.168 isn't reacheable

Hi Francesco,Yes, you are

Hi Francesco,

Yes, you are right. ACE in bridge mode should just pass the traffic. Doesn't look like a ACE problem. Does it work if you take ace out of picture?

Thanks Kanwal as you said

Thanks Kanwal as you said probably i Should investigate on other configuration.

Thanks

Hi Francesco,Just to add more

Hi Francesco,

Just to add more a bit, A bridge group is very similar to routed mode except ACE cannot NAT pass through traffic, vlan's cannot be shared and couple of other things but client's should be able to access the server as in before.

But also whether in bridge or routed mode, ACE does create flows and applies other security parameters if configured to the traffic. This is for security. Also, ACE should know the MAC of the device to forward the traffic to. Can you check if ACE has the MAC of the destination? You can also put a route for testing purpose and see if that resolves the issue. That should probably be the quickest way to check if ACE is creating any issue here.

Regards,

Kanwal
