Cisco Firewall :: ASA5510 - Routing From EzVPN Client To Non-LAN Zone

Feb 24, 2013

I got a Problem with Routing on a ASA5510.
 
I have ezVPN Clients connected to the ASA5510. Those Clients are assigned an IP from 192.168.236.0/24 Pool.
 
I have a Router of a contractor connected to a dedicated ASA Interface called IBIZA with IP Net 10.100.10.0/24 and the Router itself with the IP 10.100.10.1. Behind that Router is another private Network which I need to reach from the ezVPN Clients.
 
The Connection from the ezVPN Clients to the "LAN" Interface/Network on the ASA works fine, but I cannot reach either the Contractor Router (10.100.10.1) nor the Network behind that.
 
From the LAN Network (on the LAN Interface) I can reach both the Contractor Router and the Network behind.
 
When I use the Packet Tracer Tool from the ASDM it tells me that the Traffic goes through but ends on the LAN Interface. But it should end on the IBIZA Interface or am I wrong here ?
 
What do I need to tell the ASA to route the Traffic from the ezVPN Client to the Contractor Router and back ? I have set up the ezVPN Connection as full-tunnel so all Traffic goes through the VPN Tunnel. That shouldn´t be the Problem.

Cisco Firewall :: 2901 / ZBFW - DMZ-Zone To In-Zone Access

Jun 9, 2012

I have a Cisco 2901 which terminates a Class C address pool. I have split the Class C address pool into 3 sub-nets and 2 zones and created a non-addressable pool (private pool):
 
dmz-zone : x.x.x.0 TO x.x.x.127 (x.x.x.0/25)
in-zone: x.x.x.128 TO x.x.x.159 (x.x.x.128/27) & x.x.x.160 TO x.x.x.191 (x.x.x.160/27)
private-zone: 192.168.x.0 TO 192.168.x.255 (192.168.x.0/24)
 
I have configured private-zone NAT to use address pool x.x.x.161 TO x.x.x.189 within the in-zone.
 
Within the:
 
dmz-zone - are servers for : DNS, Syslog, SIP & HTTP/HTTPS in-zone - is a SMTP mail server which is behind VPN Gateway/NAT, TomCat (Application Server) and PostgreSQL Server private-zone - is where all standard users are operating from and they can access the SIP & HTTP/HTTPS servers within dmz-zone My problem is that I cannot seem to configure the ZBFW to allow the dmz-zone HTTP/HTTP server to redirect to in-zone TomCat server.
 
I do not want to make the TomCat server generally visible and am instead using the Apache proxy/ajp13 to connect from dmz-zone server to in-zone server.However I cannot seem to get anything (including icmp) to work from dmz-zone to in-zone.
 
I have Policy:

POLICY-DMZ-IN (dmz-zone to in-zone) which has:
any any udp/tcp inspect
any any icmp inspect
unmatched traffic DROP/LOG
 
But I still cannot get anything from dmz-zone to in-zone...Could the POLICY-DMZ-IN be being overridden by other dmz-zone to out-zone policies?

NOTE: I have routing rules for each of various sub-nets and all out-zone to dmz-zone, out-zone to in-zone and private-zone to out-zone, in-zone and dmz-zone routing works ok, so it appears problem is with ZBFW not routing table.

Cisco VPN :: 3825 IOS EZVPN Client Timeout

Jul 10, 2011

I have a 3825 configured as an EZVPN server with 881 routers as clients.  One issue I am seeing is that sessions don't seem to time out, such as when a peer's public IP changes.  Show crypto ISAKMP peer shows the same host (using device certificates for authentication) with multiple public IPs establishing sessions.  I have ISAKMP keepalives configured on the router.

Cisco VPN :: Client Behind EzVPN Remote (ASA 5505)?

Feb 2, 2012

I try to configure a simple EzVPN infrastructure:
 
EzVPN Server (CISCO2811, hostname cme) < -- > EzVPN Remote (ASA5505, hostname ezvpn-asa) < -- > Client
 
Attached you find both configuration of the EzVPN server and remote. The tunnel is getting up and if I ping from the ASA to the Router, I see the packets getting encrypted:
 
ezvpn-asa# ping 172.16.100.1
...
ezvpn-asa# show crypto ipsec sa
interface: outside
Crypto map tag: _vpnc_cm, seq num: 10, local addr: 172.16.100.2

[code]....
 
If I connect a client with IP address 192.168.1.2 to the interface eth0/1 and do a ping to the cme, I don't see any packets getting encrypted. I don't have any idea about VPN, I just need it for a wireless lab environment. What do I have to configure on the ASA, so the inside traffic is encrypted?

we're currently evaluating how we can attach our web based business application to the AD Agent in order to perform Single Sign-On against it. Our users are connecting via VPN to an ASA 5510 which is configured to use our Active Directory for authentication. After access granted the users may access a web server with our business application and should be automatically logged-in there without having to re-type their credentials.

I've got some ASA5505 which run as EzVPN clients in NEM, connecting to a ASA5510 as head-end. The ASAs are configured with a CSM and AUS. But whenever they are getting a new configuration through the AUS they stop trying to establish an EzVPN connection to the head-end. After a "reload" they run with the new configuration and establish the tunnel as expected.

Cisco Firewall :: 1811 / Zone-Based Policy Firewall Configuration

May 16, 2011

I have two 1811's connected in a lab using a ipsec vpn tunnel (using a switch to simulate an internet connection between them).I am trying to configure one of the routers as a ZBPF just to allow a remote windows login (DC on the firewalled side, workstations on the other side).I'm trying to verify that the zbpf is working, but it doesn't seem to stop anything.  I had match icmp added to the class-map, but took it out to test if icmp would fail.  It didn't.  Basically, I don't think the firewall is working at all.  Any thoughts on how I can configure this so that the policies will work between zone-pairs?

Here's an quick drawing:

Here are the configurations:

 Local router:
 hostname sdc-1811-LocalLab

boot-start-marker
boot-end-marker

no aaa new-model

Cisco Firewall :: 2911 Router Zone Firewall And IP NAT Enable

Mar 20, 2013

I have a simple setup where I have a 2911 router with three interfaces, Inside, Outside and a second "Inside" interface which is labelled as a DMZ. The Zone Firewall applied to the "DMZ" is actually Inside (until I can work through problems). I need to be able to access a device on the DMZ via its external IP so I have designed NAT to use IP Nat Enable commands. This is now working for me fine. However, since utilising IP Nat Enable, my zone firewall now denies return TCP / UDP traffic and consequently I no longer have any internet access. Looking at the syslog messages, the reason for this is that the router is denying these return flows not because they are matching the outside-to-inside policy, but rather they are matching the outside-to-SELF policy. The router seems the detect that the internet traffic is being returned to SELF, when in reality the NAT rule should pick this up and forward it to inside. I can understand why this is happening, because I am NATting all private / inside traffic behind the external IP of the router, which is assigned to the Gi0/0 interface. [code]

Cisco Firewall :: Zone Based Firewall Performance On ASR 1004

Sep 11, 2011

we are experiencing performance issues on ASR 1004 with ZBF as our campus edge router.Symptoms:

- sending small packets from inside zone to outside zone, for example UDP packets without payload
- this way I can generate up to 150.000 pps traffic (testing with packeth software, but we have had a real example with some kind of worm/virus)
- CPU load is about 1% (yes one!) to 2% all time !! (weird)
- ASR response to pings rises very quickly up to 5 seconds which makes box unusable dropping everything what goes through ZBF (so internet connection is gone)
- if I do the ping directly from box, it seems to work fine (no rules from self to outside zone in ZBF)
- if I remove interfaces from inside and outside zone (so disabling ZBF) and do the test again, ASR response goes from normal (0.2ms) up to 2ms (still sending 150.000 pps) and everything seems to work fine)
 
According to Cisco Datasheets: routing, Qos, Zbf ... on ASR 1000 with RP1, ESP10 should be done in hardware with up to 17.000.000 pps performance.

Cisco Firewall :: 2951 Zone Based Firewall

Feb 16, 2011

I am confiuring ZFW on a Cisco 2951 Router. The router has the following interfaces: [code]Port Channel 1, 1.5, 1.10, 1.15, 1.20 have been added to the zone called IN-OUT. All the subinterfaces correspond to an internal VLAN.The router is connected to a MPLS network and has a BGP peer on interface MPPP. Over the MPLS network, an ecrypted DMVPN tunnel to HQ has been built (tunnel 0). EIGRP is the routing protocol running over the tunnel.Traffic coming in from HQ has to be firewalled on this router (don't ask me why!!). As a result, I am configuring ZFW on this router.
 
1-The router itself does not need to be protected, only the servers in the remote offices. That being said, I am not planning to create any self zone on this router. I don't want to break BGP, therefore the MPPP interface will NOT belong to any zone. Is this the correct way to do it?
 
2-The tunnel 0 interface will belong to OUT-IN zone that will protect all incoming traffic into this site from HQ. So when writing class-maps for the traffic coming INTO this site, do I need to write any class-maps for EIGRP or ESP? My guess is no, since that traffic will not be coming into the site, but rather just terminating on the router.

Cisco VPN :: ASA 5520 - Traffic Not Routing Between Remotes Using EzVPN With NEM

Cisco Firewall :: Routing Between PIX 506E And ASA5510?

Mar 17, 2013

There is a PIX 506E and ASA5510, with different connection to service provider. Problem is Apple remote users can't access resources protected by the PIX506E.  Apple users can access resources protected by ASA5510. Physically the PIX and ASA are in close proximity with no physical connections.  Is it possible for Apple users to authenticate with the ASA and the traffic get routed to and get authenticated by the PIX, inorder to access resources?Due to bandwidth restrictions, a DMZ on the ASA will not be created at this time inorder to consolodate firewalls.  Currently 2 x T1 is the connection between ASA and ISP; 1 T1 connects PIX to ISP.

Cisco Firewall :: Hair Pin Routing On ASA5510

Jun 3, 2009

I wanted an ASA to do hairpin routing.  Here is the situation.  A client was running there internet through a partner's WAN.  They do not have a layer3 switch/router, and the defautl gateway on there network was actually the the partner's equip.  They recently purchased there own internet circuit and an ASA5510.  I initially tried putting in the nat exception and permit same security interface and static route on the ASA so that traffic bound for the extranet segment would be routed back out the inside interface toward the gateway to the partner's WAN.  Pings worked right away, however no applications would work: no web traffic, application traffic, anything.  My only guess is that the ASA does not like this in relation to stateful traffic flow, and the fact that since the partner's gateway is on the same subnet, you end up with asymentric routing.

Cisco Firewall :: ASA5520 And Public IP Zone

Apr 5, 2011

I'm trying to setup a zone behind my firewall with complete publicly routeable IP addresses for 3 servers. The reason I'm doing this is I am in the network setup stage of an OCS implementation, and OCS connections don't behave well with NAT.
 
My device is a ASA5520. I have an internal zone, and a dmz zone. These are done via standard NAT configurations.
 
My question is this:
 
Is it possible to setup connectivity to the outside with internal servers that have Public IP's directly on their NIC's? Another little detail of interest is that this ip space is seperate than the one that's on current Outside interface facing our ISP. However we own both address space.

Cisco Firewall :: ASA5510 Dynamic Routing And Static NAT

Dec 10, 2011

I have a ASA5510 with 2 internal interfaces (inside1 and inside2 same security level) configured with OSPF for dynamic routing with 2 routers to corporate subnets. I have a server in a private subnet that needs to be accessed from Internet. So static pat is used in ASA with the command
 
static (inside1, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255
 
As OSPF is in use, the subnet 192.168.1.0/24 may be reachable from interface inside2. When I tried to configure the static command for inside2,
 
static (inside2, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255.the error message came out "WARNING: mapped-address conflict with existing static...". Is this just a warning, or this is not possible in ASA.

Cisco Firewall :: ASA 5540 Use For Protection From Internet Zone

Mar 7, 2012

-1x Cisco ASA5540
-1x Catalyst 3750x-48T (L3 Core Switch)
 
Id like to seek expertise on validating a simple firewall setup.
 
Do i trunk core switch traffic to the cisco ASA OR assign L3 link instead? It is basic understanding that the Cisco ASA is usually use for protection from our internet zone.A typical Cisco ASA setup would consist of outside, inside, dmz zone.
 
L3 core switch consist of 20 VLANS20 vlan needs to be blocked from each other. Eg Wireless Vlan does not have access to Server Vlan etc etc. 

what is the best practise to filter ip address within vlan from reaching each other.Should i trunk all my vlan to the Cisco firewall? (For easy vlan restrictions: but is that best practise?)Or do ACL on the core switch itself? but what if i have tons of servers ip that needs specific ports blocking or etc.How would i be able to manage all my ACL on the core switch.
