How are the VLANs on the ASA 5505 connected?
I have an ASA 5505 firewall connected by a trunk port to a Catalyst 2960. Vlans have been configured and assigned to interfaces on the firewall, and trunk ports configured on both the firewall and the switch. I believe it’s configured correctly, because the switch sees the vlans I configured from the firewall.

How are VLANs assigned to interfaces on the firewall?
Vlans have been configured and assigned to interfaces on the firewall, and trunk ports configured on both the firewall and the switch. I believe it’s configured correctly, because the switch sees the vlans I configured from the firewall. I also have two windows computers, each connected to switchports confgured for two of the vlans.
Is it possible to communicate between VLANs without NAT?
Using same-security isn’t bad. If you set all the interfaces to the same security level, they can communicate without a NAT configuration. Access is still controlled through an ACL applied to the interface. If you prefer you could NAT the entire subnet or just the host or NAT 0 the subnets.
Why is my Asa firewall not connecting to Cisco switch?
The Problem: You’ve set up a trunk link between a Cisco ASA firewall (5505, 5510, et al) and a Cisco switch (2960, 3560, et al). However, you’re not able to establish a connection between them at either Layer 2 or 3. If you look at the interface counters on the firewall, you may notice that you’re piling up a bunch of “L2 Decode Drops” errors.
How does trunking work on an ASA firewall?
As it stands now, VLAN configuration on an ASA consists of simply adding the sub-interfaces for the VLANs, which in turn automatically enables 802.1q trunking on the physical port, and that’s that.
