HOW DO I CONFIGURE VLANs ON ASA 5505?

This is a duplicate question already answered, no?

I had closed the other question before you answered it.... because I thought it was a different issue than the originally intended. I awarded you the points on the last question. We can use this thread if you like.

That works for me.

Ok then, starting over... can help me with the CLI to:

1) disable DHCP on Ethernet Port 0 (VLAN1), comes by default
2) configure the Ethernet Port 0 (VLAN1) to use a static Public IP 216.123.2.192/255.255.255.248 DNS1 207.3.65.22 DNS2 207.3.65.32 , security 0
3) configure the Ethernet Port 1 (VLAN2) to use an static Internal IP 10.0.15.254/255.255.255.0 , security 100
4) does ASA need a Policy to allow traffic outgoing traffic to the internet from vlan 2 through vlan 1 ?

.... thanks

config t

 dns server-group DefaultDNS
   name-server 207.3.65.22
   name-server 207.3.65.32

int vlan 1
 description private network
 nameif inside
 security-level 100
 ip address 10.0.15.254 255.255.255.0

int vlan 2
 description public Internet
 nameif outside
 security-level 0
 ip address 216.123.2.193 255.255.255.248

int e0/0
 description public Internet
 switchport access vlan 2
 no shutdown

int e0/1 description private network
 switchport access vlan 1
 no shutdown
end

specifying an ip address on the vlan interface should disable dhcp.  

by default, a higher security interface can pass traffic through a lower security interface.

by default, traffic that originates from a client inside the private network is allowed back through the public interface to the client.

hey thanks for the fast response !

...let you know how it goes

Did you set this box back to the default configuration?  It appears to have its original config (or some of it).

int vlan 1
 description private network
 nameif inside
 security-level 100
 ip address 10.0.15.254 255.255.255.0
 exit

int vlan 2
 description public Internet
 nameif outside
 security-level 0
 ip address 216.123.2.193 255.255.255.248
 exit

int e0/0
 description public Internet
 switchport access vlan 2
 no shutdown
 exit

int e0/1 description private network
 switchport access vlan 1
 no shutdown
end

true... after resetting it I played with the GUI... I'll reset it to fact-def b4 applying the commands in the CLI


...what should I do about the DNS issue?

ciscoasa(config)#  dns server-group DefaultDNS
ciscoasa(config-dns-server-group)#    name-server 207.3.65.22
ERROR: DNS must first be enabled.
ciscoasa(config-dns-server-group)#    name-server 207.3.65.32

oh man sorry, wrong thread... let's use the new one.

thanks.

sorry again jesper... I'm going crazy here. This is the right thread... bear with me pls, and dont loose interest...

Let's talk DNS.  What do you need the firewall to do with DNS?

I've configured ISA Server before, where for example you have to configure the outside NIC with info  the ISP gives you:

Public IP / Mask / Gateway / DNS1 / DNS2

That's what I'm trying to get my VLAN2 to work.

Are you machines on the private network getting the IP address via DHCP or are that statically addresses?  If DHCP, what is the DHCP server?

...no DHCP available on the private network, the VLAN1 (inside) will need to be assigned a static IP like the config you gave me before.

int vlan 1
 description private network
 nameif inside
 security-level 100
 ip address 10.0.15.254 255.255.255.0
 exit

int vlan 2
 description public Internet
 nameif outside
 security-level 0
 ip address 216.123.2.193 255.255.255.248
 exit

I'm wondering how and where it is that you configure the  Gateway / DNS1 / DNS2 for the VLAN2 (outside) ports.

Let's talk DNS.  What does the ASA need to do with DNS?  If it's not to provide DNS servers via DHCP, what do you need it for?

The gateway:
  route outside 0.0.0.0 0.0.0.0 IP.OF.NEXT.HOP

...ok, I see where you're going, ASA doesn't need a DNS configured, the machines in the private network do

...what started this line of conversation is the alert I got after applying the config commands you gave me

ciscoasa# config t
ciscoasa(config)#
ciscoasa(config)#  dns server-group DefaultDNS ***
ciscoasa(config-dns-server-group)#    name-server 207.3.65.22
ERROR: DNS must first be enabled.
ciscoasa(config-dns-server-group)#    name-server 207.3.65.32
ERROR: DNS must first be enabled.
ciscoasa(config-dns-server-group)#

***I figured there ought to be a DNS enable command after that line

ok... like this then?

ciscoasa# config t
ciscoasa(config)# dns domain-lookup outside
ciscoasa(config)# dns server-group DefaultDNS
ciscoasa(config-dns-server-group)#    name-server 207.3.65.22
ERROR: DNS must first be enabled.
ciscoasa(config-dns-server-group)#    name-server 207.3.65.32
ERROR: DNS must first be enabled.
ciscoasa(config-dns-server-group)#

Are these valid DNS servers?

noup... sample ones to test it
