Cisco Firewall :: Can't Get Traffic Flowing Between VLANs On ASA 5505
Aug 20, 2012
I've got an ASA 5505 with the Security Plus license that I'm trying to configure.
So far I have setup NATing on two VLANs, one called 16jda (VLAN 16 - 10.16.2.0/24) and one called 16jdc (VLAN 11 - 10.105.11.0/24).
From each subnet I am able to connect to the internet, but I need these subnets to also be able to talk to each other.
I have each VLAN interface at security level 100 and enabled "same-security-traffic permit inter-interface", and I have setup static NAT mappings between the two subnets, but they still can't communicate.
When I try to ping there is no reply and the only log message is: 6 Aug 21 2012 09:00:54 302020 10.16.2.10 23336 10.105.11.6 0 Built inbound ICMP connection for faddr 10.16.2.10/23336 gaddr 10.105.11.6/0 laddr 10.105.11.6/0

I have ASA 5505 Firewall with security plus license, I configured two V LAN 1 and V LAN 5 as my inside V LAN for different sub net, i need to route the traffic between this two V LAN's through ASA. I configured
int vlan 1
nameif inside
Security level 100
Ip address 172.16.100.1 255.255.255.0
[Code] .........
The problem is i am not able to ping other sub net, for ex my PC is in V LAN 1 not able to ping 192.168.22.1 ... For troubleshoot i type debug icmp trace while pinging other subnet
ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=4608 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=4864 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=5120 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=5376 len=32
I turn off the firewall on my local machine.

I have a ASA 5505 with the security plus license. I have 7 vlans, 2 are guest vlans for wireless and wired connections. I am allowing traffic from the guest vlans to any with the http & https protocols I have ACL's in place before the allow all rule that do not allowed traffic from the guest vlans to the other vlans. Is there any way to have all traffic from the guest vlans to always go to the outside interface for the http & https traffic in stead of trying to go to the other vlans first, I know I have the ACL's in place to prevent the traffic but if I would feel better if I had this in place as well.

I'm currently using ASA 5510 with software 8.4.1 and I have an issue with nat configuration. I used the following config line:nat (inside, dmz) source dynamic LAN Pat1 destination Server1 Server1
The traffic is not flowing and when I use Packet Tracer, packets are dropped at the NAT rule with the following error: Drop-reason: (acl-drop) Flow is denied by configured rule.The only ACE I have is permit ip any any.

I have manually configured the Firewall ASA 5510 from existing PIX to match the configuration, however when I connect the firewall to the Network, no traffic is flowing in either direction. I have the Inside network on the 172.29.0.0 subnet and the outside network on 20.2.0.0 subnet. I am attaching the cofiguration file.

im attempting to setup a L2L VPN between an 1841 and an NSA 2400, via the SDM.The Tunnel comes up, and when I test connectivity it shows as being successful, but I do get an error stating:-
"A ping with data size of this VPN interface MTU size and 'Do not Fragment' bit set to the other end VPN device is failing. This may happen if there is a lesser MTU network which drops the 'Do not fragment' packets."
From my reading this shouldnt cause all traffic to drop though, right?
Currently I cannot ping or telnet to services from one end of the tunnel to the other. I was able to ping momentarily from the Sonicwall end at one point, but this disappeared shortly afterwards (without my changing anything regarding the config).
All of the ACLs created were populated through the SDM.

i have a gateway router going to the internet....using public IP addresses on both interfaces. starting on Monday, traffic would suddenly stop flowing from the inside of the network going out, though i can still ping the outside interface , but when I log in to the router I am able to ping to the internet. so its like traffic is not passing from the outside int to the inside int. I have a 3900 router. other thing is, when i restart the router it will work for some time and then just stop again....

We have 3560 switch with following IOS. version 12.2(55)SE3 and image name is C3560-IPSERVICESK9-M. On one of the interface we need to know what are traffic is flowing.
Do we have "ip nbar or ip route-cache" support on this switch IOS? Is there any other way to find out which protocol traffic is flowing through that interface.

I have configured multicast(ip pim dense-mode) on two 2911 that are connected by a Multilink( 3 Mbps) Wan connection.The configuration works fine for awhile and sometimes all day but at some point one of the Multilink interfaces stops passing multicast traffic.I perform a SH Multilink 1 on the interfaces and one show multicast packets incrementing and one does not, it just stops.The problem acts like there is a buffer that gets full and after that happens it just stops working.

I have two 1841's, setting up a Lab WAN in Packet Tracer. I have one of the 1841's run to a DSL modem, then out to the cloud and the same setup on the other end... from the cloud to the DSL modem and to the 1841 on that end... I have all green lights, so that tells me layer 2 is up, but I'm trying to figure out
what IP to assign the routers to test pinging and getting traffic flowing. but the DSL Modem's have the public IP's and dynamically assign an IP to the routers? I've also tried setting up a static IP on the routers fa0/0 interfaces and the pings fail.. Wondering what I am missing to get these two talking.

We are in the process of rolling out iPads to our offices. As part of this implementation, we need to print from the iPads to our network printers. Our network printers are mostly HP and Xerox and do not have native Apple AirPrint capabilities. As such, we have been using the FingerPrint software to share out the network printers as Apple AirPrint printers. We have a mixture of switches at our offices. Most offices utilize a 3550 PoE switch. In these offices the AirPrint traffic is being transferred successfully and everything works great. In the offices which are using 3560 PoE switches, the traffic is never seen at the iPads. We are using EnGenius EAP300 access points connected into the Cisco switches to provide wireless access to the iPads. Both 3550 and 3560 switches are running iOS 12.2(25). What might be stopping/blocking the AirPrint traffic on the 3560 switches?

We have a data center with servers set up for different projects, some servers from partner companies and several small LANs. The traffic between all those needs to be controlled and firewalled. The servers and LANs are divided into different subnets and VLANs. Physically, their traffic is aggregated on a couple of 4506 and then sent to a FreeBSD server, where the logical gateways are set up and traffic is filtered between them.The BSD server is dying and having it there is incorrect in the first place, so we are planning to replace it with two ASA (5520) in failover.The question that arises is how to correctly implement firewalling between VLANs. Originally we thought to set up the firewalls in transparent mode and logically terminate VLANs on a stack of 3750 switches behind them, but would that filter the traffic between the VLANs? Then we thought to perhaps terminate the VLANs on the ASAs, use routing mode, and do filtering there, as well. Or should we implement multiple contexts? We have about 20 VLANs and all of them differ in rules of what should go there. None of this can be concidered an "inside" - trusted - zone, nor "outside". Internet and external links are connected and filtered in a different place.

I have an ASA 5505 and I have the three regular vlans, outside, inside and dmz. The best would be only have outside and inside and skip dmz, but without explenation there is not possible to have more then two clients in whats now dmz because of a mac filter on third party device.
So as security is concerned dmz and inside is equal, one to one and there should be full access between them. I ran the wizard and said that the only way traffic not should be possible to flow is from dmz to outside.
In the NAT rules the onle rule is
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0
But traffic from one way or the other dmz to inside, og inside to dmz it says in log
3Dec 06 201215:38:39305006172.17.6.1053portmap translation creation failed for udp src inside:192.168.6.102/49358 dst dmz:172.17.6.10/53 From documentation I have an image with network drawing from documentation. What do I have to do allow traffic btween inside and dmz, both ways.

I 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
subnet 192.168.2.0 255.255.255.0
nat (guests,outside) dynamic a.b.c.d

so I look up ASA5505 licensing and for VLAN support see: 3 (no trunking support)/20 (with trunking support)*
I need 3 VLANs...inside, outside, and DMZ..but when it is creating the third (DMZ) it says I am only allowed to have 2 VLANs and can only create the third if its set to not forward traffic. ?

I have 2 ASA 5505 firewalls and 1 cisco 3560 switch.
One ASA 5505 firewall and cisco 3560 switch located at SITE-A. Another ASA 5505 firewall located at SITE-B.
Below is the my connectivity:
Site-A IPSec VPN Site-B
cisco 3560 <----------------------------> ASA 5505<------------------------------------------------------------------------------------> ASA 5505
I planned to create 5 vlans in my cisco 3560 switch. these 5 vlans needs to have internet and needs to access Site-B.
I will write on dafault route to firewall in my cisco 3560 switch. Is ASA 5505 supports this scenario??? If it is then how to configure ASA 5505 firewall.

I have a an ASA 5520 connected to a Layer 3 (3750) switch (Inside) and a connection to a 2960 switch (Outside) to get to the internet. . I have created vlan interfaces on the 3750 switch and enabled ip routing on the switch to enable the vlans to communicate with each other.
Vlan Interfaces on the switch:
Vlan 100 172.17.1
Vlan 200 172.18.1
Vlan 300 192.168.3.1
I want the devices connected to the 3 vlans to be able to pass through the firewall and get out to the internet.I have connected the ASA to the 3750 by routed interfaces (10.10.10.1) --------- (10.10.10.2) and they are able to ping each other.I have also put a default route on the 3750 sending all traffic from the switch to the ASA inside interface (10.10.10.1)The issue that i am having is that the ASA also connects to a 2960 which has a connection to the Internet, and they are handing off an ethernet connection from the 2960 that sits in VLAN 55 (Vlan 55 is the Internet accessible vlan).How do I configure my ASA to send all traffic from my (3) vlans to the interfaces that connects to the 2960 switch?

I have an ASA 5505 with the security plus software and I'm trying to find out how to assign 2 public IPs to the outside interface and have each IP routed to a separate internal VLAN. For example, IP 1 = X.X.X.1 routed to 192.168.1.0 and IP 2 X.X.X.2 routed to 192.168.2.0. I was told this was possible and I've been trying to find configuration examples, but I can't seem to get anywhere and now I'm getting desperate because I'm scheduled to install it this weekend.

We have a BT Infinity broadband circuit which terminates at a vdsl modem, I've plugged an ASA 5505 into the back of this modem and gone through the ADSM quick setup wizard (yes I'm that much of a beginner!) The config that's been generated is pasted below, the symptomns I'm seeing are;
The ASA is setup with PPPOE on the internet connection, I assume this is correct as if I do a show IP on the ASA I'm getting an IP address that has been assigned, if I change the password to the wrong one then I get no IP (as expected).
If I ping from the ASA to an internet connection I'm getting "no route" error messages, if I try a "ping outside x.x.x.x" then I get no repsonses.
The ASA can ping it's external IP, the client machines can ping it's internal, however nothing appears to be able to get out.
ASA Version 8.4(1)

hostname xxxxxx
enable password xxxxxx encrypted

We have 110mbps internet service. When we have the 5505 behind the cable modem, our speed drops to 55mbps or so. If we remove the 5505, we see the full 100mbps. I assume the 5505 can handle the speed; if so, what other things should I be looking at?As an aside, we used to have 50mbps wich worked fine, then the ISP upgraded to 60mbps and the through put dropped to 30mbps (It always seems to be half)

My understanding is for insight to outside we need global and NAT, and for outside to inside we need static and ACL? Traffic goes to high to low, I'm just start working with 5505 recently.

I have a Cisco ASA 5505 that I have configured. The outside interface is vlan 2 and the inside interface is vlan 1. Port 0 of the ASA is configured to be in vlan 2 and is connected to the ISP provided subnet. Port 1 is connected to my private LAN subnet. I have an additional router connected to Port 2 for guest connectivity. Port 2 is configured to be a member of VLAN 2 so that it can access the ISP provided subnet. From the device connected to port 2 I can ping the vlan 2 interface address of the ASA and from the ASA I can ping the Default gateway of the ISP provided subnet. For some reason the router on port 2 cannot ping the default gateway of the ISP provided subnet. If the vlan were working the same as a vlan in a switch, I would expect to be able to do this. why it is not working or what I can do to get it working?

I am fairly new to configuring ASA's. I have an ASA 5505 with one outside interface and three inside interfaces (inside1, inside2, and management). I need inside1 and inside2 to be able to talk to eachother but cannot work out how to make this happen. They are both configured to the same security level and the 'Enable traffic between interfaces with same security level' box is ticked. I have also tried adding appropriate NAT and Access rules. The packet tracer suggests the rules are correct for allowing traffic flow between interfaces but obviosly this may not be the case.

I am trying to switch out a cisco pix 501 firewall with a cisco ASA 5505 firewall. I am not very familiar with all of the commands for the firewalls and have always relied on a standard command line script that I use when building a new one. Unfortunately, my script is not working with the 5505. What I am doing wrong with the following script? I've masked public IP info with xxx.xxx.xxx and I run it right after restoring the firewall to the factory defaults. I am able to get out to the internet if I browse directly from one of the servers, but cannot access a web page when trying to browse to it from an outside network. [code]
