I have a Cisco ASA 5505 with a Security Plus license. I'm trying to have two physical ports provide two separate VLAN connections to the same physical network.
I have both VLANs defined properly - named "inside" and "test". I have the test VLAN assigned to Ethernet0/1. The goal is to have a completely segregated "test" network that cannot communicate with the inside network even if the proper subnet is applied to the NICs.
It works, somewhat, but I'm definitely missing something. When I have the cable plugged into e0/1 connecting it to my switch I get heavy and random packetloss from traffic over both VLANs - but traffic does flow to/from the Internet over both VLANs. When unplugging the cable traffic on the inside interface reverts to its rock-solid state.
Any direction would be greatly appreciated.
