Cisco Firewall :: 5505 - Route Traffic Between Two VLANs Through ASA

May 30, 2011

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.

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

Cisco Firewall :: ASA 5505 - All Traffic From Guest VLans To Always Go To Outside Interface

Mar 15, 2013

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.

Cisco Switching/Routing :: ASA 5505 - Port 80 Route Between Vlans

Apr 14, 2013

I have 2 Vlans with seperate networks and want to create a route between one server in vlan 465 to another server in vlan 436 via port 80.Vlan 465 has a ASA 5505 inside that IP address 89.254.12.35 will be initiating the connection to address 10.200.1.213.
 
-Vlan 465: server address 10.200.1.213
-Vlan 436: server address 89.254.12.35
 
However for extended security I would like to restrict the firewall opening to an IP to IP opening.

Cisco Infrastructure :: ASA 3750 Firewall To Control Traffic Between VLANs

Jan 20, 2013

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.

Cisco Firewall :: Routing Between VLans On ASA 5505?

Dec 5, 2012

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.

Cisco Firewall :: NAT With Inside / DMZ VLANs On ASA 5505 V8.4(2)?

Sep 16, 2012

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

Cisco Firewall :: Configuring VLANs In ASA 5505 Switch

Apr 19, 2011

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.

Cisco Firewall :: Configure ASA To Send All Traffic From (3) VLans To Interfaces That Connects To 2960?

Apr 18, 2013

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?

Cisco Firewall :: ASA 5505 Route Monitoring Options?

Oct 22, 2012

We have one pair Cisco ASA 5505 located in different location and there are two point to point links between those two locations, one for primary link (static route w/ low metric) and the other for backup (static route w/ high metric). The tracked options is enabled for monitoring the state of the primary route. the detail parameters regarding options as below,
 
Frequency: 30 seconds               Data Size: 28 bytes
Threshold: 3000 milliseconds     Tos: 0
Time out: 3000 milliseconds          Number of Packets: 8

[code]....
 
I'm not sure if the setting is so sensitive that the secondary static route begins to work right away, even when some small link flappings occur. What is the best practice to set those parameters up in the production environment. How can we specify the reasonanble monitoring options to fit our needs.

Cisco Firewall :: Multiple Route Commands On ASA 5505?

Jan 7, 2013

I want to know with an ASA 5505 w/ Security Plus License I get up to 20 VLANS/Named Interfaces.I have a customer that is getting a new subnet of external IP addresses from their service provider and a different default gateway to accomodate re-hosting their datacenter at their main office instead of at a Colo. My question, when building out their new DMZ, can I have multiple route 0.0.0.0 commands?
 
Example.
 
Current Default Gateway 1.1.1.X
 
Internal hosts 192.168.1.0 use and are natted to 1.1.1.X
 
New Default Gateway for DMZ Servers 2.2.2.x
 
Internal hosts still use 1.1.1.X, but server hosts in 192.168.1.3 should use 2.2.2.X -- there are also a bunch of pre-existing static NAT rules for these servers such as 2.2.2.30 translates to 192.168.1.30.
 
I think I would accomplish this by using the following:
 
route inside 0.0.0.0 0.0.0.0 1.1.1.X
route DMZ 0.0.0.0 0.0.0.0 2.2.2.x
 
Would this be correct?

Cisco Firewall :: Multiple WAN IPs Routed To Separate Internal VLANs On ASA 5505

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.

Cisco Firewall :: Possible For 5505 To Route / Map Renaming Private IP Addresses Through Its External Port

Jul 25, 2011

I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
 
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
 
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.

Cisco Firewall :: Getting Any Traffic Out Of ASA 5505

Jul 24, 2011

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.

Cisco Firewall :: VLAN Traffic On ASA 5505?

Aug 15, 2011

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 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've  setup my Cisco ASA 5505 in transparent mode. I have a Cisco 1841  connecting to the ISP (DHCP client) and F0/0 for inside. The 1841 is the  DHCP server.  I have my ASA 5505 behind the 1841 in transparent mode  (Vlan 1 for Outside and Vlan 1 for inside). The router config is  good as when you connect a computer straight to the inside interface I  get DHCP and can go to internet, no problems what so ever. But When  you're trying to go through ASA isn't not working.  if I add a ip any any statement to the access list it will work but  having an "ip any any" in a access list is like having no firewall at  all.
