Unable to see all interfaces configured on Cisco ASA 5505
Posted on 2012-12-30
I have a Base license ASA 5505 that's restricted to 3 vlans
vlan1 is the inside interface 192.168.1.1
vlan2 is the outside interface x.x.x.x
vlan3 is being set up to be an isolated IP range so Ethernet 0/7 is enabled with a security level 100 and an IP of 192.168.168.1 (restricted traffic flow is set to restrict traffic to vlan1 (inside))
Now both the 192.168.1.1 interface and the 192.168.168.1 interfaces are connected to the same switch and from there I have a single test machine that is also connected to the same switch.
There is no DHCP set on either interfaces.. I have a static address set on the workstation of 192.168.168.2
my problem is I am not understanding why I can not even ping the 192.168.168.1 interface.
If I switch the workstation over to 192.168.1.2 I can see the 192.168.1.1 interface fine.
Am I missing something with the "restricted traffic flow" setting
Enable traffic between two or more interfaces with the same security level is unchecked (ADSM)
And enable traffic between two or more hosts connected to the same interface is also unchecked (ADSM)
Any help would be appreciated

I have not touched the vlan configs at all on the switch, I assumed on HP procurve switches that all the ports are untagged.
I can post the config shortly .
I can post the config shortly .
If your workstations is Windows system, check arp result.. "arp -a" in command promt.
If the result is "192.168.168.1 xx-xx-xx-xx-xx-xx dynamic", Layer 2 is working correctly which mean problem area will be ASA only.
If the result is "incomplete", i would prefer direct testing which is your workstation is directly connected to 192.168.168.1 interface.
Hope this help.

If I connect a note book directly to the interface every thing works fine. I have subsequently upgraded the ASA to the Security + model. and now have a total of 4 VLANS.
as long as I isolate the interface on its own switch every thing works fine.
I know the config you see below is missing a translation rule... but right now I just want to be able to ping the interface
I apologize ahead of time the config has changed a little since I first posted.
