Cisco Firewall :: ASA 5510 - Static VLAN NAT

Mar 9, 2012

One of our customers has asked us to Nat from the LAN to the Voice LAN based on destination IP address in order to access a public phone server through a vendor managed voice router..
  
                                Internet for everything else
                                                   |
                                                   |
Inside ------------------------> ASA 5510 -----------------> Voice router  ------>  outside to public phone server only
10.10.1.0/20                         10.10.1.7/320               172.16.20.1/24
Voice------------------------->
172.16.20.0/24               172.16.20.254/24
 
Here the ASA5510 has an interface in both networks and the inside network can ping the voice network through the firewall by using non at acls. The phone server can only talk to the 172.16.20.0/24 network. So I need to nat the 10.10.1.0/20 network to the Voice interface on the ASA 172.16.20.254/24.
 
So I think I need the following static but I get the error below:
 
static (Inside,Voice) interface 10.10.0.0 net mask 255.255.240.0
WARNING: All traffic destined to the IP address of the Voice interface is being redirected.
WARNING: Users will not be able to access any service enabled on the Voice interface.
ERROR: Invalid net mask with interface option

Cisco Firewall :: 5510 - Convert Static NAT To PAT

May 27, 2013

I have an issue, of two parts. The first part I believe I have figured out, just the second part I am unsure of. I have an ASA 5510, currently, there is a mailserver that is static NAT'ed to one of my ISP routed IPs (not the IP of my main Dynamic PAT/Outside interface).  I need to convert this over to PAT for ports 25,80,443, etc  (standard ports).  I know I need to remove the static NAT statement and add in the PAT statements, but I need traffic from that machine to continue to go out the IP assigned to it by the static NAT.
E.G.
 
1.1.1.1 <- main public IP on outside interface, everything gets internet through this IP
1.1.1.2 <-> 10.10.10.10 static NAT to mailserver, secured with ACLs
 
I need to enable the mailserver to continue to appear to the world as living on 1.1.1.2, due to MX records and rDNS settings, etc...

The terminology for this setup escapes me at the moment.

Cisco Firewall :: ASA 5510 - Static NAT For Outside Access Not Working?

Sep 19, 2011

I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
 
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
 
4    Sep 20 2011    16:20:33        fw_outside_ip    62678    outside_host    2001    Deny tcp src outside:outside_host_ip/62678 dst inside_host:inside_host_ip/2001 by access-group "outside_access_in" [0x0, 0x0]
 
When I try to use the packet tracer to simulate the outside traffic, I get the following
 
5    Sep 20 2011    16:17:41        inside_host    2001            Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:outside_host/1065 dst inside_int:inside_host/2001 denied due to NAT reverse path failure
 
I've got over my NAT statement and access rule and can't find anything wrong with either.
 
Here are the pertinent NAT and access rule...
 
static (inside_int,outside) tcp interface 2001 inside_host 2001 netmask 255.255.255.255
 
access-list outside_access_in extended permit tcp host outside_host host inside_host eq 2001

Cisco Firewall :: 5510 8.3 (1) Static Nat For Web Servers And FTP Server As Well

Sep 13, 2011

I got the charge of a ASA 5510 running with 8.3(1) version.Found that this is simple config with Patting for inside host and couple of Static Nat for web servers and FTP server as well.
 
There is lots of other configuration being done,I assume for the purpose of just R&D by the previous administrator.I need to understand if the following Nat statements holding any relevance?
 
Where we are running Only  NETWORK_OBJ_192.168.0.0/23 subnet at inside and there is no other subnet defined in rest of the statements.i.e 10.0.0.0/27 and 192.168.1.128/27 doesn't exist at all.

Cisco Firewall :: Unable To Reserve Port 443 For Static PAT In Asa 5510

Jul 15, 2011

This problem applies (in my case) to our ASA5510. The issue here is that the http service on the ASA is runnnig off of the standard port 80. Login to the firewall and run the following.no http server enable http server enable 8080,Now you should be able to add a NAT/PAT on port 443 to another server of your liking. Just remember when you attempt to use ASDM to manage the ASA in the future to specify the new port 8080.

Cisco Firewall :: ASA 5510 - Static Route By Interface Or Destination

Sep 21, 2011

Is it possible to assign a static route to an interface and not globally on a ASA 5510 ver 8.3.
  
I have two links between my offices one for Data via a VPN and one for video traffic which is a secure connection with QOS end to end.
  
All interfaces are on the same security level of 100 except Outside which is 0.
  
Office 1 Interfaces ASA 5510
 
 
VLAN  1               vOffice1Data       10.40.1.0/24
VLAN  3               vOffice1Video     10.40.2.0/24
VLAN 5                vInterOffice       10.40.5.0/24     (QOS  connection Between Offices)

[Code]....

At the moment if I try and access data from VLAN 1 to VLAN 4 it gets to the destination ok going through the static route and over the vInterOffice connection but the problem is VLAN 4 returning the traffic. This fails because there is no static route back to VLAN 1. If I create a static route from Office 2 to VLAN 1 then it will route all my data traffic over it as well.

Cisco Firewall :: ASA 5510 - Multiple Static Route Tracking

May 15, 2013

I am trying to set up my ASA5510 the fail over of ISP when it can't ping three different IP. I create three different tracking to three different IP using sla monitor & track rtr. But when I do

   route isp2  0 0  yy.yy.yy.yy  50
   route isp1  0 0  xx.xx.xx.xx  31  track 1
   route isp1  0 0  xx.xx.xx.xx  32  track 2
   route isp1  0 0  xx.xx.xx.xx  33  track 3

the last route will replace the previous two and only the last route command takes effect.Is there anyway I can set up the fail over to ISP2 only when it can't ping three different IP from ISP1?

Cisco Firewall :: ASA 5510 Static Map - Outbound Flows Through Global Address

Nov 30, 2011

I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
 
Here are what I believe to be the relevant configs.
 
interface Ethernet0/0
description New 6mb circuit
speed 100

[Code]....

So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.

Cisco Firewall :: ASA 5510 And 3750 VLAN Routing?

Dec 14, 2011

I am working on the exact same configuration as noted here [URL] that uses subinterfaces on the asa. I have two interfaces on my stacked 3750's configured as trunk ports (primary ASA on primary 3750 stack member, secondary ASA on secondary 3750 stack member).
 
My questions is what should the DG be configured on the 3750. Can I keep the 3750 in L2 or will I have to enable L3 routing? Should the VLAN interfaces be configured.
 
The port that the ASA is configured with has 3 subinterfaces on VLAN 100, 200, and 300.
  
The subinterfaces are G0/2.100, G0/2.200, and G0/2.300.I am in the middle of converting from 3 separate DMZ switches, each attached to their own port on the asa which is their default gateway to one physical port on the ASA broken into 3 subinterfaces which then connect to stacked 3750's. The stack will then have the 3 separate DMZs in actual separate VLANs.
 
My goal is to leave the default gateway for each dmz on the ASA so I don't have to modify other areas of the ASA config.

Cisco Firewall :: VLAN Tagging To ISP Through ASA 5510 To Remote Site

Oct 25, 2012

we have a base license ASA 5510, and been trying to get ICMP working to check that we're routing and not hitting any NAT translation. We have a VLAN280 setup to ISP for VPN link to remote site and another VLAN281 for internet access for internal users.
 
Users can browse internet from (name _inside interface e0/1 access port) which is fine. When I do a ping to remote office through the VPN I get a response pinging from VLAN280 name VPN_Link. When I do a ping from name inside interface I don't get a response both are security level 100 with same-security-traffic permit inter-interface configured.

Cisco Firewall :: Pass Management VLAN Traffic Through ASA 5510 In Transparent

Mar 10, 2013

We have a small cisco 1800 series workgroup router that seperates our network from the outside world.  The data coming into our network goes into the router on interface fa0/1 and comes out on interface fa0/0.  fa0/0 is split into 2 sub-interfaces (fa0/0.2 and 0/0.3).  These sub-interfaces correspond to a desktop and server vlan on our network.  The workgroup router is connected to a 3560G trunk port (we'll call it switch 1) and switch 1 connects to another 3560G (we'll call it switch 2). Recently I was asked to add another layer of security to our network by installing an ASA 5510 firewall and forcing certain types of traffic to authenticate using their domain credentials for our network.  The firewall was set up between the router and switch 1 in transparent, multi-context mode.  There are 2 security contexts, 1 for the desktop vlan and 1 for the server.  Both have the same security settings applied to them since we want the same behavior regardless of whether they are trying to access the servers or the workstations.

Cisco Routers :: RV180 NAT Five Static IPs To 5 VLAN Subnets

Feb 14, 2013

I have five static IPs that I would like to fully utilize, by NAT'ing them to internal VLAN subnets.I read that the RV180 can do this, but I am having difficulty in finding a working recipe.I have assigned xxx.xxx.xxx.2 to the RV180 WAN interface.
 
I have created four additional VLANs 2-5 and assigned to ports 1-4 with subnet interfaces 192.168.2.254, 192.168.3.254, 192.168.4.254. and 192.168.5.254,I have set the default VLAN to untagged on all ports. VLANs 2-5 are set to tagged for their respective port (1-4) and exclude for other ports.I have set DHCP relays to 192.168.1.202 which is my DHCP, DNS, AD services.
 
I read some months ago that when the first static IP address is assigned to the WAN port, that the VLAN ports will accept tagged packets on their ports and NAT them to the respective successive static IP (sounds a bit like magic to me). Regardless, I read that the RV180 can provide VLAN subnet NAT to up to 5 static IP address. I am not looking for 1 to 1 NAT, not the same.  I want to perform NAT on the four additional VLANs in the similar manner that VLAN 1 (default DMZ) IPs are NAT'd to the static WAN address. As in everything outbound on 192.168.1.0 is NAT'd to xxx.xxx.xxx.2
 
Additionally I would like all DHCP assigned by my DHCP server which I believe is accomplished with the DHCP relay setting on all five VLAN subnets, which point to the DHCP server 192.168.1.202
 
Lastly, I am trying to configure VPN connectivity into my DMZ network. I have configured a few accounts, enabled for PPTP. I have configured PPTP and am issuing 192.168.1.70-80. The VPN connection seems to work great without the use of Cisco quick VPN. I can see the remote picking up the 192.168.1.71 IP address as the VPN connection is made. From the remote I can ping IP addresses on the DMZ subnet 192.168.1.X   How can I configurer the Cisco RV180 PPTP server to provide the DMZ DNS ipaddresses? These addresses need to be 192.168.1.201 and 192.168.1.202
  
I feel I am almost there, in working out the VLAN subnet to Static NAT. I suspect it will be some routing configurations. The ISP business gateway on the WAN side that I point my router to which is owned by Verizon, is xxx.xxx.xxx.1 I have a /29 making IPs xxx.xxx.xxx.2-6  available to me.

I need another set of eyes.  it was initiating the tunnel last week but not completing the connection.  Now its not doing anything.  i am going backwards.  Below is my remote ASA config.

I have  a laptop directly attached to the inside interface.  The PC and ASA can ping each other. The test interface is the one I am trying to use. Does my default route need to point to 192.168.0.1?  Or is the remote peer correct?  I thought the remote peer was correct? The 4G modem is like a pass-thru device. If I connect my laptop to it I can get out to the internet.

Cisco Switching/Routing :: 2800 Series To Set Static Routes Per Vlan

Aug 3, 2012

Is there a way to set static routes per VLAN?Example VLAN 100 sends all traffic to 192.168.1.1 and VLAN 200 sends all traffic to 10.1.1.1. (2800 Series RTR)I have 5 networks that have their own gateway to the Internet via satellite link. Those networks run over the same infrastructure on separate VLANs. They frequently send traffic to each other, which gets sent over a slow SAT link. I introduced a router to the network and would like to set all my hosts default gateway to the local routers sub-interface then have a static route that send all traffic that is not on one of my 5 networks back to that VLANs respective SAT modem to get routed out over the Internet.

Cisco Switches :: SG300 Static Route Default Gateway Per VLAN

Jul 27, 2011

We have recently purchased a Cisco SG300 and have been configuring it. [code] The VLANs have ACLs set up to prevent any communication between the Holly and Tempo VLANs (and their associated WAN VLANs).Each VLAN has a WAN available for it's use, which connects to external networks (including the Internet).In order to facilitate this, we have set up all the necessary ACLs and routes and confirmed that this all works.However, the problem comes when we assign the static routes that specify the default gateways.We add the two static routes below:

-0.0.0.0 next hop 10.10.200.254 metric 1
-0.0.0.0 next hop 192.168.200.254 metric 1
 
In this case, only one of the VLANs has WAN access.  It is either Holly or Tempo (it can be either if the order the static route is added is changed).What we need is to force Holly to use Holly WAN and Tempo to use Tempo WAN, but we cannot see a way of doing this.Effectively, we want the following static routes: [code]

Cisco Firewall :: 6509 / FWSM VLAN Configuration Mismatch And Some VLAN Deleted

Aug 12, 2012

We  have 6509 VSS with FWSM Module and we have created two context on it, one is INTERNALL CONTEXT othe is EXTERNALL Context? We have spanned various VLANS in switches and FWSM context level.  All VLAN Gateways are configured in context level.
 
Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During  migration of devices from one Dc to a new DC  we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC  and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
 
During the activity ( Primary switch movement )We powered off the Primary switch  and mean time before shifting into new Data center  We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
 
Later  we had moved  Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE  and  primary device was not responding and devices  went off network and immediatly we  removed the VSL link and brought up  primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original  VLAN  ip 10.200.112.1 has become  10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
 
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.

Cisco VPN :: 5510 - L2TP Over IPSEC Static NAT

May 22, 2013

I have a 5510 that i have configured for L2TP over IPSEC, not using AnyConnect. The first, and most prevelant being, VPN clients are unable to ping/access any of the hosts that are assigned a static NAT from the inside interface to the outside interface.  I was able to circumvent this by adding another static NAT to the public interface for the incoming clients, but this caused intermittent connectivity issues with inside hosts.  The second issue involves DNS.  I have configured two DNS servers, both of which reside on the internal network and are in the split_tunnel ACL for VPN clients, but no clients are using this DNS.  What is the workaround for using split tunneling AND internal DNS servers, if any?
 
i've had two different CCNA's look at this numerous times to no avail.  A ping from a VPN client to any internal host works fine, unless it is one that is NAT'd.  You can see in the config where i added the extra STATIC NAT to try and fix the issue.  And this works perfectly across the tunnel but only intermittenly from the internal 10.1.4.x network.
