How are you try to communicate between the two servers? Can you ping each other? Web?

Are both servers in a switch off the same ASA interface?

Devices within the same layer 2 VLAN should not have any problems communicating with each other. Such communication does not pass through the firewall. The traffic gets dropped on the wire and the device with the MAC address in the destination field picks up the packet.

I have 5 servers behind my asa5505. outside world gets to them perfectly and they go out perfectly. but i can not get server 1 to talk to server 2. (192.168.2.2 to talk to 192.168.2.5). any ideas? below is my config

one is plugged into ethernet4 and other is in ethernet5. I have them plugged into the back of the asa 5505. The 2 servers can not ping each other at all. Maybe i dont have the ports included in the vlan maybe?

Which VLANs are those ports in?

16 years 3 months ago #26349 by flipzz
in Ethernet0/4 and Ethernet 0/5 I do not have those Ethernet ports labels in the Vlan. The above config is what is running. SHould I define unter the Ethernet0/4 and 5 interfaces that they are in the "inside" Vlan?
