I’ve actually borrowed a old cisco layer 3 switch and replaced the layer 2 switch in the DMZ, reprogrammed it, gave it a DMZ management VLAN and a DMZ vlan, added an ip route within the switch and just used the ethernet0/2 interface on the ASA normally with a ip address (no vlans) and it all worked – but i dont know why all the problems with the layer 2 switch…hope you can help out. The second switch has a default gateway to the first switch which is layer 3 and has a ip route command that points to the inside of the firewall (the two switches are connected with a trunk which allows for vlans 5,10 to go through it).ĭo you reckon it all boils down to the access-lists in the firewall? The inside network, you have 2 switches (there is a staff vlan 5 and a managament vlan 10). However, from the inside network where the staff are, i cannot access the web server in the DMZ. So now i can ping from the firewall the web server (10.20.20.3) and the vlan 4 ip (10.20.20.2) on the switch. On the other end, on the ASA, ethernet0/2 i have no shut, no speed, no nameif (nothing) and i created a subinterface ethernet0/2.4 (the vlan on the switch is also vlan 4 and its ip is 10.20.20.2 for instance while the ip of the web server is 10.20.20.3) and then as above all 8 ports belong to the same Vlan however, 7 of them are mode access, while port 0/8 is trunk. In any case, i setup a single Vlan on the 8 port dmz switch.

It is a layer 2 switch (i cannot use ip route – i cant apparently even use encap dot1q line apparently because it only supports dot1q and not Cisco proprietery ISL so i just have to write switchport mode trunk which automatically means dot1q trunk 0 software 12.2.44.). Separately, there is a small 2960 8 port switch for the DMZ. The inside connects to switches which are on the inside network. Currently, 3 interfaces – one for the outside, one for the inside and one for the dmz. Switch(config-if)# switchport trunk encapsulation dot1 Switch(config)# interface gigabitethernet0/8 Switch(config-if)# switchport access vlan 40 Switch(config)# interface gigabitethernet0/2 Switch(config-if)# switchport access vlan 30 Switch(config-if)# switchport mode access Switch(config)# interface gigabitethernet0/1
Please correct me if I am wrong.ġ.Create VLAN 30 and 40 databases on the layer 2 switch for inside network and assign physical port to VLAN 30 and VLAN 40.Ģ.Create Trunk Port on the layer 2 switch and connected to ASA in this case will be GigabitEthernet0/1Ĭreate VLAN and Trunk port on layer 2 switch. That is, higher security levels can communicate with lower security levels but, by default, lower security levels can’t communicate with higher security levels unless you configure NAT and Access Control List to allow traffic.īy reading the eBook “If you configure subinterfaces (VLANs) on a physical interface, then this physical interface must be connected to a Trunk Port on a Layer 2 switch”.īy the statement above I assume that I also need to create VLAN30 and VLAN40 database from layer 2 switch as well. Therefore the communication between different subinterfaces is governed by the same rules as physical interfaces. Communication between subinterfacesĮach subinterface is a different security zone with a different security-level.
Then you must configure access ports on the switch belonging to the above Vlans accordingly in order to connect hosts to the access ports. The same Layer2 Vlan numbers which are configured on the firewall appliance (in our example the configured VLANs are 10,20,30,40) must also be created as Layer2 Vlans on the switch. In order to implement the concept of Vlans and subinterfaces in a network, you must connect each physical interface of the ASA to a trunk port on a switch which must support 802.1q trunking.

ASA 5510: Max 100 VLANs (with the Security Plus Software)īelow is a snapshot of a configuration example of VLAN subinterfaces:Īs you can see from the configuration above, we are using two of the physical interfaces ( GigabitEthernet0/0 and GigabitEthernet0/1) to create total of four different network segments (security zones).Įach Vlan is also a different Layer 3 subnet and also a separate security zone with its own security-level.ASA 5505: Max 20 VLANs (with the Security Plus Software).There are limits on the number of VLANs supported on each ASA model, according to the following list:
