I just installed a new ASA 5505 for an office with three internal subnets. The three networks can each get online fine and ping eachother, but cannot browse to shares on the two internal networks other than their own. How do I configure the ASA to allow all traffic between these three inside networks?
192.168.152.0
192.168.152.0

A pix 515E with software 8.0(4)28 connects the inside and outside networks. There are some servers in "outside" that have addresses overlapping with the internal subnets (192.168.10.25 and 192.168.10.26), and those servers have a reverse route only to a specific subnet (172.16.5.0/24). [code) Now to the problem. 192.168.10.26 is an HTTP server. On the pages it has hyperlinks pointing to http://192.168.10.25, the browser tries to access that server and, surely, fails, as the target server is only available by sending requests to 172.19.100.1, with the packets being DNAT'ed.Is it possible to rewrite the packet's body, replacing all occurances of url... I know it's a kludge, but other options are even worse.ASA eith 8.4 software? IOS router?
View 2 Replies View RelatedI 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?

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
[code]....
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?

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.
isp -> x.x.x.1 /29 (outside asa) (inside network) x.x.x.2 /29
Is this possible?
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 can't ping the ASA inside interface but I see its MAC address in the swtich's table.

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

But these commands don't seem to be available on a 5505.

We have a Cisco ASA 5505 (v7.2(3)) with a "fairly" normal configuration yet we have a problem where it appears UDP/53 traffic is denied on our inside network.
here is output from our sys log:
SyslogID Source IP Dest IP Description

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.)

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. There is no log reference in the switch and the interface shows as UP. The standby ASA has no problem, both interfaces on the switch is up. As soon as I failover the units over, the active node inside interfaces drops.

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.

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.
Previous 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]

I've an ASA 5505 connecting to a vdsl modem. The ASA is doing the PPPoE encapsulation.
