Cisco Firewall :: ASA 5510 - Terminate Second ISP Link On One Of DMZ Interface?

Jun 20, 2011

On our ASA 5510 we already have one ISP link terminated on outside interface. There is correspoinding nat and global configured for outbound access to internet.
Now we need to terminate second ISP link on one of the DMZ interface to have redundancy for the primary ISP. 
When primary ISP link or router is down we need to send all the traffic to secondary ISP router.  How do we configure NAT and global for this condition that only when primary is down then only this NAT -Global should be used.  Do we have anything like object tracking associated with the NAT-global.
So that as long as Primary  RTR - object is up ASA will use the first NAT-Global pair. When primary ISP is down RTR-Object is not reachable then ASA will perform the second NAT-Global operation.
Also can we have default route pointing to Outside interface (primary ISP router) and in case of primary router failure it will point to secondary ISP. Do we have "track"  in the static route commands on ASA.

Cisco Firewall :: 5510 Security Plus To Terminate Client VPN Access For External Support Team

Aug 7, 2012

I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
3. does the CSC module provide any web proxy functionality?

Cisco Firewall :: ASA 5510 - Dual Internet Connections / Routing DMZ Traffic

May 29, 2012

I am having an issue when implementing an additional internet connection on our ASA 5510. The new connection is "TWCOutside".  I was my understanding that static NAT would force our externally hosted servers (Email, PPTP VPN, and FTP) to continue to utilize the "ATTOutside" connection.  Our remote site-to-site VPN traffic has two static routes configured to force it to continue to use the ATTOutside connection.When I switch the metric on the route to 1, and change out default dynamic xlate to use "TWCOutside", it "mostly" works as expected.  Email, the PPTP VPN server, and our remote site-to-site VPN server continue to use the ATTOutside connection as designed.  Our end users begin using the new connection for thier internet browsing.
However, our FTP server, in the DMZ, completley loses outside access.  It cannot ping to, or resolve DNS queries.  The is a static NAT statement for this server, as it is using one of our dedicated public IP addresses.  I need it to continue to do so for the next few weeks.Effectivley, we just want to give our end users internet browsing on the new TWC link, but leave everything else on the old ATT link for the time being.  The only problem I am having is the DMZ connection.  I am currently "rolled back", so no one is using the new connection until I figure this out.  I can easily switch the metric and dynamic PAT back to using the TWC connection, but I need to have some things to try with the DMZ before doing so.

Cisco VPN :: How To Use ASA 5510 To Terminate A LAN To LAN IPsec VPN

Aug 6, 2012

We have an ASA 5510 running 8.3 that we need to use to terminate a LAN to LAN IPSEC VPN.
Problem is we only have one public address available so have had to configure the link between the ASA and the Internet Router on private addresses.
Is it possible to NAT the public address to the inside or outside interface of the ASA and terminate the VPN on that interface?

Cisco VPN :: Dual ISP Links And SLA On ASA 5505-50?

Nov 3, 2011

I have two Internet links:ISP1: only Site 2 Site VPNsISP2: only HTTP/HTTPS traffic and incoming remote access VPNs With the security plus license I could correctly configure them both as active at the same time on the same ASA device. Also, I've successfully accomplished the following traffic separation:
Site to Site VPNs goes out through ISP1HTTP/HTTPS traffic goes out through ISP2 The customer request is that, when ISP1 fails the S2S traffic is relayed through ISP2 -> This is working fine, I've already tested!But when ISP1's service is restored and that link is working fine, I want that the S2S VPN traffic gets relayed through it again automatically, which didn't happen. My question is: using SLA will the S2S traffic be relayed through ISP1 again automatically when it's services are restored? If not, which technology should I use to accomplish this?
PS: This is all configured on only 1 ASA 5505 whose license was upgraded.

Cisco Firewall :: Dual DSL Lines For 5510?

Jun 13, 2011

My remote office staff are stating it takes "forever" to open simple work/excel files.I think forever really means more than 5 seconds.My main office has a 5510.  I have a brand new server in place here that my remote offices vpn into.
Those remote offices have 5505.
Each office has a dsl connection.  Their download speeds range from 7mb to 10 mb and their upload speed are 0.5 mb to 0.8 mb.My first thought was to add a second dsl line to my main office.  Then have dsl line #1 serve my main office and office 2.Then have dsl line #2 serve offices 3, 4 and 5.
Would this speed up the opening speeds of my remote offices?If so how challenging is adding the second dsl line into my 5510?

Cisco Switching/Routing :: 2800 Series - Dual ADSL Links?

Jan 31, 2012

In a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?

Cisco Firewall :: ASA 5510 Nat / Routing DMZ With Dual ISPs (4 Legged)?

Apr 11, 2013

I am in the process of configuring a ASA 5510 to replace an older PIX.  This change is part of migrating to a new ISP, so the process is complicated by the existence of two outside interfaces.  I have virtually everything working, but there is a requirement to be able to access hosts from the internal networks using both their private IPs and their public IPs.  The older PIX took care of this silently with little configuration, but the ASA has me twisted on the details.  Some of the hosts with public IPs are on the internal network and some are on a DMZ (not my design, inherited).  For the internal ones I implemented hairpinning to take care of the requirement, but I am having trouble with the DMZ based hosts.. Since there are two external interfaces each internal host has two IPs and two static NAT rules to handle incoming traffic from each external interface.
The routins and dynamic NAT entries we have in place take care of accessing the hosts using their private IPs on the DMZ, but I cannot figure out how to get the public IPs to work from the internal network.  It seems like a simple Static D-Nat shoudl do it, but when I add a Static D-Nat on the DMZ the public IP works, but the private IP breaks..  Is there a way to get them both to operate ?
Network layout looks like this (IP ranges altered):

DMZ Class C
Outside  Class C
Outside2  Class C


After applying it I could access the public IP ( from the internal network, but I could no longer access the DMZ IP ( from the internal network. Is there any way to get this configuration to allow access to both IPs from the internal network ?
The problem here is that there are website links based on the public IP and the DNS is split so DNS returns the internal IP to users. As a result both need to be accessible from the internal network.. Not my favorite design, but the client (or in this case the boss) is always right so I need to get it working somehow.

Cisco Firewall :: ASA 5510 Dual ISP Active / Standby Fail Over

Apr 2, 2013

I have a dual ISP, 1 primary and 1 secondary terminated on fa0 and fa2 on our ASA respectively. ASA was configured so that, when the primary fails, the secondary kicks in.  [code]
It was until yesterday that we experienced downtime on the primary ISP that the secondary doesn't do the fail-over. I have to manually configure the device to use the secondary ISP. Currently, I'm looking at maybe this has something to do with the licensing.We are currently using a Base License, should we be upgrading to Security Plus?

Cisco VPN :: ASA 5510 With Dual ISPs Split Traffic Between VPNs And Internet

Jul 1, 2011

I need to know how to setup my ASA with dual wan links. 1 is 10/10 fiber, other will be a 50/5 Cable Wideband link. The 10/10 fiber is currnetly being used for VPN's and Internet, (about 20 point to point IPSEC vpn's currently).
I want to add the Wideband link and use the "Tunneled (Default gateway for VPN traffic)", feature for the current fiber link and the new Wideband link for any other internet traffice. I tried this however as soon as I set my fiber link to "Tunneled (Default gateway for VPN traffic), I lost all connectivity.
I also setup my "VPN" link with the "tunneled" option and my "INTERNET" link with a default route to the internet. This would only let me ping internet sites from the ASA device but not from client computers, also the VPN's would not come backup.
I have tried the sla setting with a DSL line for failover and that works good, i've since got rid of the DSL and want to utilize 2 wan links for different purposes/traffic.
ASA 5510, SSM-10      1GB RAM
ASA version                8.4(1)

Cisco Firewall :: Terminate SIP Connection On ASA 5505?

Apr 15, 2013

I have a SIP trunk in my Florida office connected to a Cisco 2851 ISR. I'm using Unified Communications Manager 8.0 and life is great.
We just opened a new office in Spain and now the fun begins.  We created a site-to-site VPN tunnel using ASA 5510 in Florida and ASA 5505 in Spain. We can register IP Commuicator phones in Spain but when they make calls it shows up as a Florida call. We need it to show up as a Spain call.
We are thinking to get a SIP trunk into the Spain office but I only have a ASA 5505 over there. Can I terminate a SIP connection to it? Is this the best option? If not, what is the recommened setup?

Cisco Firewall :: 1921-SEC / Terminate Each IPSec Connection In Separated Zone

Apr 26, 2011

We are using a CISCO1921-SEC Router. On the "WAN" side we have 1 public IP Adress assigned by DHCP. At the moment we are using the WAN Interface with a crypto-map as endpoint of some IPSec connections. We set up a zone-based-firewall with "WAN" and "LAN" zone. In this setup all IPSec Endpoints are on one Interface - connections to the "LAN" zone can be managed by rulesets. What about connections between IPSec connections and the zone "self".We like to terminate each IPSec connection in a separated zone. How can this be configured ?Each one on a "tunnel inetface" with "tunnel source ..." binding ?

Cisco Switching/Routing :: 3560CG Switch Terminate On Internet Modem

Feb 4, 2013

I am facing with Cisco 3560CG Switch. We have a Cisco WS-C3560CG-8PC-S (Cisco Catalyst 3560-C Switch, 8 GE PoE, 2 dual-purpose uplinks, IP Base image) switch which will be a core switch and the internet link from the ISP is terminated on a Modem. The ISP configured the internet modem and provided the details such as Gateway IP, Subnet Mask, DNS IP address, Usable IP Address Block,  to configure the switch, where ew have connacted the Modem. When, I verified the details, there were only 4 IP addresses available under Usable IP address block. Spoke with the ISP and they confirmed that they cannot increase the IP Addresses (some limitation on the Modem) in the pool and we have to do NATing at the switching (Which we can't do, because of IP Base image limitation). About the network, it will be a flat network with only one VLAN which is used for Wireless Guest Access.

Cisco Firewall :: ASA 5500 WAN Failover MPLS / Internet Using Dual ASA

Jun 1, 2011

I am putting together a solution for a client. The client has an MPLS circuit and internet as a backup circuit. I understand that we can do WAN failover using ASA5510 appliance.Now, if i am adding dual ASA5510 active/standby mode, How do i automatically failover WAN circuits to standby firewall if both MPLS and Internet circuits are connecting to primary ASA5510. Should i connect MPLS circuit to ASA1 and Internet circuit to ASA2? Ideally, i want both circuits to connect to primary ASA5510 for automatic WAN failover. My concern is , if the primary ASA5510 fails which has WAN and Internet circuits connected , do i need to manually switch connection from primary to standy? The goal is to fully automate wan failover and asa failover .

1) Is it best to configure a separate Vpc VLAN i.e 1010

2) Is it best to configure a vrf context keep-alive

Cisco Firewall :: Can ASA 5505 Support Two External Links

Oct 3, 2012

Does the ASA 5505 will allow the addition of a 2nd external link to its configuration? I know the device is capable of Redundant or Backup ISP Links, but that’s not what I need. I will have two different links for two different purposes. Currently we are using the ASA 5505 just for Internet access, so only the ISP link is connected, very basic configuration. We are planning a connection to a client’s global (MPLS) network and we need to be protected against any traffic coming from that network, ergo we need to use a firewall for connection to that external link.Now with the final configuration the Internet traffic must keep being routed to the ISP link, and some other traffic must be routed to the new external link. Can the ASA 5505 be configured for this scenario?

I have 2 interfaces that sould be applied to it let's say outside1, outside2. The server is reacheable through each outside interface, the outside interfaces is selected uppon dynamic routing and that is working OK.
So if link outside1 is up the Nat follows this schema --
that works fine, but I want that automagically changes over when the link outside1 is down to -- know I can't have a NAT with 2 IPs and 2 different interfaces (ASDM doesn't allow me to), is there a way to implement this??

Cisco VPN :: ASA 5510 - Dual WAN Connections

Nov 29, 2011

Context:1- My company has one ASA 5510 configured with Site-to-site VPN, Ip sec Cisco VPN and Any Connect VPN.2- We use ASA to connect to the single ISP (ISP 1) for internet access. ASA does all the Na Ting for internal users to go out.3- A second link is coming in and we will be using ISP 2 to load balance traffic to internet (i.e. business traffic will go via ISP1 and “other” traffic will go via ISP2).4- A router will be deployed in front of the ASA to terminate internet links.5- No BGP should be used to implement policy (traffic X goes via ISP1, traffic Y goes via ISP2). Questions:How do I get this done, particularly, how do I tell the router, for traffic X use ISP1 and for traffic Y use ISP2? PBR is my friend?Since I will be having 2 public Ip Addresses from the 2 ISPs, how do I NAT internal users to the 2 public Ip addresses ?. Finally, which device should be doing the Na Ting? The ASA just like now or move Na Ting to the Router?
