ASA 5505 and DMZ, I have a Base License.
What do I need to do for access inside network to DMZ?
I successfully configure, internet Access for DZM and inside network, web server can be accessed from internet, but I have problem to configure communication from inside network to DMZ.
We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?

I have a Cisco ASA 5510 configured to access the internet, with an:
inside interface (ethernet 0/1) 130.130.0.254 and outside interface (ethernet 0/0) x.x.x.x
I have now configured another inside interface (ethernet0/2) on ASA with the IP 172.16.0.254 and I have connected it directly to another switch with a management IP 172.16.0.5.
The problem is that the two inside interfaces (130.130.0.254 &172.16.0.254) cannot communicate with each other thus the e0/2 172.16.0.254 interface cannot access the internet.
I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

We have ASA 5550, I have a citirx server in the dmz which is natted statically to a public ip address for port 443. The dmz server communicate with our internal server (i.e. AD) for LDAP authentication. I have a static transparent nat from inside to dmz for the internal server's communcation with dmz.
When accessing the application from inside the network on the internal web server it works perfectly fine and authenticates with the AD.But when accessing from outside, the reach the citrix server and then the AD authentication fails, basically it works intermitantly. I have tried to check the communcation from the DMZ server to the internal server and the icmp works perfectly fine, even I am able to telnet on the ports specified on the internal servers from the DMZ servers. I tried to look into the logs on the ASA and this is something that looks suspicious to me.

I have a 5505 that currently has inside/outside interfaces and everything is working just fine. I am trying to create a DMZ that will essentially be just for vendors/guests. the DMZ will have full access to the outside (Internet) but no access to the inside. I am using the FW for DHCP, and 8.8.8.8 and 4.2.2.2 for DNS. I currently have 1 laptop in the DMZ vlan, and it is getting a correct IP, and it is showing 8.8.8.8 and 4.2.2.2 in ipconfig. I can ping/tracert 8.8.8.8/ 4.2. 2.2/74.125.137.147(what url... resolved to on a laptop connected to the inside vlan), but I cannot ping nor browse to url.... [code]

View 10 Replies View RelatedI have a 5505 with Base license running ASA software v8.4(2) that has been working happily for a while with an inside and an outside VLAN.
The outside has a single statically configured public IP, and I have a number of static NAT rules to expose a few internal servers as well as Dynamic-NAT for all devices on inside to gain access to the Internet... the main bits of the config are below:
interface Vlan1
nameif inside
security-level 100
ip address 192.168.1.1 255.255.255.0

interface Vlan2

I now have a requirement to add a "dmz" VLAN for guests to have access to the Internet using a dedicated wireless AP, but not to any of the inside resources. As the ASA has a base license I have configured "no forward interface" to the inside vlan, which suits the purpose fine
interface Vlan12
description Used only for guests access to the Internet - no access to the corporate resources
no forward interface Vlan1
nameif guests
security-level 20
ip address 192.168.2.1 255.255.255.0
My problem is that when I try to add NATing from the dmz to the outside I get a:
ERROR: Address a.b.c.d overlaps with outside interface address.
ERROR: NAT Policy is not downloaded
with either:
object network guests_subnet
subnet 192.168.2.0 255.255.255.0
nat (guests,outside) dynamic interface
[code]....
Having had a look at the ASA Configuration guides, all the examples I can see with several "internal" VLAN's being NAT'ed use one external IP per VLAN - is this a feature/restriction of the ASA software? Are there any workarounds? Or is the overlap in the error message really about the current NATing to the inside VLAN which is done on the "any" 0.0.0.0 subnet - would the following then work:
object network obj_any
subnet 192.168.1.0 255.255.255.0
nat (inside,outside) dynamic a.b.c.d
object network guests_subnet

I have an ASA 5505 with the typical inside/outside interfaces. I also have a DMZ that I've named remote for all of my ISP VLAN'd remote offices to connect. I've set the security levels on both the inside and remote interfaces to 100. From remote 192.168.71.0 network I can ping to the remote interface on my ASA, 12.230.129.66/8, but can't ping anything on the inside network, 192.168.1.0, or the web. From my ASA I can ping the router directly attached to the remote interface, 12.233.136.162/8. From my inside 192.168.1.0 network I can hit the web fine, but cant ping the remote router 12.233.136.162 or the remote network..
I dont' know if I missing something with routing, or with the two interfaces w/ same security...or what?
Here's my config. I've also attached an awesomely bad network map.

I have a Cisco 5512 x Firewall connected with Cisco Layer 3 switch 3750.I have two different WAN connections, one for Data and one for voice. Cisco Layer 3 switch is configured with 2 different VLAN's one for data & other is Voice Vlan. Switch is providing DHCP to computers and IP phones. Voice Pool 192.168.10.0/24 Vlan10 and Data pool 192.168.20.0/24 Vlan20.I need to route my data & voice traffic separately. Cisco ASA is connected with two different ISP's. So, how can I do this configuration so that Voice and Data traffic will route separately.

I will also use this to manage the ASA. I am having a problem with the network configuration of the inside interface as I can't ping the gateway and/or the in IP of the inside interface.Do I need to add any routes?
I am unable to Telnet/SSH/RDP from my inside network to my DMZ. I am not sure where the problem lies, I am able to use VNC from the inside to the DMZ (ports 5800, 5900), and also establish connection on Ports (26700-26899). I have a computer connected directly to the DMZ and those services work to all networks on the DMZ.I have attached Logs of successful VNC connections, unsuccessful RDP and Telnet sessions, and the running config.

We have an ASA5505 UL bundel, updated with this license "L-ASA5505-SEC-PL=" to enable traffic from DMZ to Inside. No NAT or rules deployed for that yet.
On the Inside we have Exchange 2007 in a single server installation. The public url for smtp, ActiveSync, OWA and Outlook Anywhere is mail.company.se. There is a static NAT for outside traffic to access above mentioned services on inside. Now, on DMZ there is the WLAN for guests to access the Internet. How ever, our Smart Phones with WLAN turned on, cannot sync to the Exchange Server on the Inside! The DMZ gets IP-addressen from ASA on DMZ Interface with external DNS configured. How can I configure the ASA to achieve the function of ActiveSync from DMZ to Inside with the public URL from the phones?
I have a cisco asa 5505 and i need a public ip address on the inside of my network without NAT. for example: I can create a static nat translation rule, but this is not what i need.

I have an ASA 5505 that I'm trying to set up a guest network on. I've configured an interface as a trunk and allowed the 2 vlans but I'm not getting any layer 3 to it. The switch connected to it is a 3560 and port is configured as a trunk with the same vlans.

I have an ASA 5505 running 8.2(1), that is configured with three interfaces as follows:
Inside (security 100) 10.0.0.0 /24
Inside 2 (security 100) 192.168.0.0 /24
Outside (security 0) internet
Inside is connected to my internal network, inside 2 is connected to the network of a sister organization, outside is outside.
I'd like to be able to route between from inside to inside 2, and have NAT translate me to inside2's address.
I have inter-interface traffic configured, and when I use a NAT exemption, I can route fine. But the resources on network 2 must see my request as coming from the inside2 interface IP.
My customer is running an ASA5505 with 8.3 code.
The have a somewhat flaky proxy between their inside LAN and the firewall. I'd like to have a configuration as follows:
LAN > Proxy > VLAN 1 (eth0/2) on ASA
and
LAN > VLAN 1 (eth0/3) on ASA
So that in the event of Proxy failure (let's just say it loses power) the eth0/3 interface will kick in.
This appears to be easily configured according to the documentation:
"The following example creates two redundant interfaces:
hostname(config)# interface redundant 1
hostname(config-if)# member-interface gigabitethernet 0/0
hostname(config-if)# member-interface gigabitethernet 0/1
hostname(config-if)# interface redundant 2
hostname(config-if)# member-interface gigabitethernet 0/2
hostname(config-if)# member-interface gigabitethernet 0/3"
But these commands don't seem to be available on a 5505.

We already have a subnet defined to inside interface and is in produciton. the default gateway is this interface ip. In that setup now I have to add one more subnet and as the first subnet is been defined in ASA indside interface, I have to assign secondary Ip to the inside interface so that new subnet users can easily reach here and go outside.

To give some clarification:
172.18.22.3 is one of our DNS servers
172.18.22.156 is a device we're experimenting with.
We've bypassed the Cisco by using a 4G wireless router with this same device - and it works flawlessly.Here is a [scrubbed] copy of our config. It is what I inherited from the previous admin - I'm not sure of all its finer points (I'm not Cisco certified -- perhaps I'm just certifiable.)

Trying to add inside routes on an ASA 5505 to point traffic to another gateway for other connected networks is resulting in the following error 6Sep 16200 819:13:5810601510.184.236.1265003810.170.54.1823389Deny TCP (no connection) from 10.184.236.126/50038 to 10.170.54.182/3389 flags RST on interface insideI believe the problem is due to the Asymetric tcp connection and the ASA is dropping the connection because it only see one half of the traffic.Is there a way we can stop the firewall dropping the TCP connections on the inside interface? i've tried removing the threat managment which didnt work.Annoying thing is were putting the ASA 5505's in to replace old Watchguard soho firewalls only the watchguards forwarded the traffic no problem at all.
View 1 Replies View RelatedI have a pair of 5505's in transparent mode and connected them to C2960S. The inside interface (which is VLAN5 on the switchport) keeps dropping, going in to error state.

I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA. Thay can ping each other. The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10. I do not need split tunneling to be enabled. The active WAN interface is the one labeled outside_cable. [code]
View 1 Replies View RelatedPrevious attempts to set up these NAT rules has been met with minimal success. We have been able to get the NAT rules created, and able to ping our inside servers and receivers from a different outside network, but every time we get that far our internal network crashes. Running the Packet Trace utility via the ASDM shows that internal traffic from the servers to the workstations is being blocked by the default implicit rule under the access rule heading that states "any to any, service being ip, action= deny". Reverse traffic from the workstations to the servers is being allowed though. In an effort to start over again, the Cisco ASA has been Factory Defaulted via the CLI, and has had it's Inside network, and Outside IP address set back up. DHCP pool has been setup for a minimal amount of addresses on the inside network, since most of our equipment will always be assigned statics. We reset our static NAT policies, and seem to be having the same problem. My partner and I have been working on this for some time now, and have ourselves so frustrated that I know we are missing something simple. [code]
