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  172.10.0.0.0 Class C
INTERNAL 10.0.0.0  Class C
Outside  1.2.3.0  Class C
Outside2  2.3.4.0  Class C

[code]....

After applying it I could access the public IP (1.2.3.50) from the internal network, but I could no longer access the DMZ IP (172.10.0.2) 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 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.

Cisco Firewall :: Dual ISPs On ASA 5505

Dec 5, 2011

We have a cisco ASA 5505 with sec bundle plus
 
We have two ISP's:
 
ISP1 (Our IP = 30.100.150.50, gateway 30.100.150.8)
ISP2 (Our IP = dynamic, gateway 20.100.150.9) - ADSL 
Our internal LAN IP range is 10.9.8.0/24
 
We want to configure the ASA 5505 to allow users via ISP2 for http traffic We then want to use ISP1 for strictly VPN and access to internal web resources (eg OWA) as we have public IP's there.
 
Our idea was to configure two gateways on the ASA (e.g. 10.9.8.5 via ISP2 and 10.9.8.6 via ISP1)
 
Then give the users gateway 10.9.8.5 for web browsing etc Is this configuration possible on the ASA 5505?

Cisco Firewall :: ASA 5520 For Dual Active ISPs

Dec 14, 2011

I inherited a network redesign project mid implementation and ran across an issue that I was not 100% sure able to be resolved.  Implementation is occurring in which the organization is changing over to a different ISP and we have some customers that will not be able to change their settings over to our new addresses from some time.  I have seen a lot of posts about fail over and dual ISP configurations, but I could not relate them to this particular scenario.

Cisco Firewall :: ASA 5505 Split Traffic On Dual ISPs

Jul 31, 2012

I have an ASA 5505 current f/w & the security plus license (to get the 3 nameif interfaces). Can I split traffic between two ISPs, (VPN traffic to one destination on a T-1 on one VLAN, and all other traffic using DSL to another VLAN) and using a different nat policy on both? I know load balacing isn't supported, only failover. I was just wondering if there was a way to make this work.

Cisco Firewall :: ASA505 - 2 Sets Of NAT Rules To Accommodate Dual ISPs

I am setting up an ASA550 ver 7.2(3) - does this need upgrading?I have my ISP interfaces setup as primary and backup I have a static route pointing out:route primary 0.0.0.0 0.0.0.0 1.2.3.4 1 Question:Do I put the next static route to be route secondary 0.0.0.0 0.0.0.0 3.4.5.6 254 Will this set a high metric on the secondary route that will only take effect if the primary route is down? I assume I will need to have 2 sets of NAT rules to accommodate the dual ISP's

Cisco Firewall :: ASA 5510 - NAT With 2 ISPs / 2 Different Public IP?

Oct 17, 2011

We have an issue with some NAT on an ASA 5510. Here is a simplified drawing of the ASA setup:So the issue is when we try to send traffic from 172.16.3.251 to 1.1.1.1 we got this message in the log:
 
Oct 18 2011 12:32:12: %ASA-3-305006: portmap translation creation failed for udp src inside
172.16.3.251 /37166 dst outside:1.1.1.1/23
 
It looks like there is an issue with NAT but maybe is cause of the DUAL ISP setup as packets are routed through the outside interface and not IPtelefoni_outisde?

Cisco Firewall :: 5510 Split Traffic Between VPN And Internet Using Different ISPs

Aug 25, 2011

What we are trying to accomplish here use two ISP's (one cable and one T1), use the Cable line for site-to-site VPN and use T1 line for all internet traffic. We currently use the following configuration: Cisco 2820 routers terminating the T1 -> HP switch -> Cisco AS 5510 port 0 -> port 1 to LAN switch (Nortel 5510)We want to force all VPN traffic (using 10.0.0.0/24 subnets - 10.0.1.0, 10.0.2.0, etc) through a cable connection, perhaps on port 2 of the ASA, then all non VPN traffic goes to the T1.

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 0.0.0.0 0.0.0.0 98.103.148.145 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 8.8.8.8, 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 WAN :: Dual DHCP ISPs On ASA5505?

I've been searching the net for days now trying to configure the ASA5505 for dual DHCP ISP use. All guides available assume you have one static.
 
After realizing that it required a Security Plus license to even configure 3 VLANs.
 
I can choose a backup interface in ASDM. It even says dual ISP enabled. Why cant there be a guide or simple configuration example or am I the only one looking for this kind of solution?
 
Customer has two ADSL internet connections and want to switch between them if they fail. No load balancing required.

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 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 WAN :: ASA 5510 - NAT / Default Route To Two ISPs

Nov 14, 2011

I am having a strange requirement. actually I am not sure it is strange or not. I am having ASA5510 with 8.4 sw version. Currently one ISP is connected to it. It is working fine. We have some servers that are directly connected to internet using another ISP connection. These servers having public IP addresses configured on their LAN settings. I need to move these servers in to the DMZ zone.
 
When i connect it to the ASA's DMZ zone,servers will get internet through the first ISP that is already configured on ASA. But i need to NAT the DMZ servers with the IP address provided by the other ISP, which even not configured on ASA.
 
So what should i do? In short my requirement is
 
1) need to NAT the server with the IP address provided by another ISP
 
2) Also note that the default route is configured for  the first ISP only in ASA
 
so Do i need to configure another default route? Do i need to make it with larger AD? So i do it will act as the secondary route only.
 
I need to make the ASA up and running for two ISP, and servers in the LAN should be able to NAT with the IPs of first ISP and ,the servers in the DMZ zone should be able to NAT with the public IP of the new ISP.

Cisco WAN :: 5510 Pickup Correct Device / Router For Multiple ISPs

Apr 3, 2011

We have plans for multiple ISPs and need to pick the correct device/architecture for that. single site: 3 ethernet hand offs (1 From ATT Fiber/10Mb pipe via their managed router, another one from ATT via Copper T1 via a separate circuit & managed router and the 3rd/last from Cable Modem/Comcast)
 
1.WAN hand off from another ISP from I will use ASA 5510 (already have) to use all the above 4 as inputs and then use the internal interface of the ASA 5510 as the default gateway for all the employees to browse the internet etc. so that1. If one one or more of the ISP lines die, we continue to operate (albeit lower bandwidth)

2. Also, we take advantage of the added bandwidth (even though it may not be the arithmetic sum of all the above).

Cisco Firewall :: 5585x - Multiple ISPs Plus WAN And DMZ

Cisco Firewall :: PIX 515e 2 ISPs Max Speed Is Slower With ISP

Apr 19, 2012

have a PIC 515e connected to two ISPs via 2 interfaces.  ISP1 is a 3.5Mbps aDSL line, and ISP2 is a 30Mbps business cable.  I've confirmed the speeds by connecting the cabled directly into a laptop and using wget to download very large files from known-fast sites.
 
For admin reasons, I need to access two specific subnets using the slower ISP1.  The rest of internet traffic should go to the much faster ISP2.
 
So I configure ISP2 as the default gateway, static routes for the two subnets to ISP1, set up NAT (PAT) and it all works like a charm.  I've confirmed that ISP1 is used for only the two subnets, and ISP2 for everything else.  CAPTUREs on the pix also confirm this.  So far, it all works great.
 
But for reasons I don't understand, my max. download speed is 3.5 Mbps (the slow DSL).  Using various speed tests and wget, I simply cannot get a download speed faster than my 3.5 Mbps DSL line.
 
 
Here is my config:
interface ethernet0 100full
interface ethernet1 100full
interface ethernet2 100full

Cisco Switching/Routing :: ISR 881-SEC-K9 Vs 891-K9 And 2 ISPs Redundancy

Nov 1, 2012

have main office of 70 people.Also I have 2 redundant ISP:One give me 20 mbit/s Other only 2 mbit/s and it is my backup ISP.
 
I have some resources in data center and I need a IPSec VPN to it and some other location. I suppose there will be up to 3-5 IPSec tunnels. I choose Cisco ISR 881-SEC-K9 with one wan port and 4 LAN switch. But know I’m looking for Cisco 891-K9. There is no security bundle for it. But in cisco.com this router is marked Cisco 891-K9 Security router. Does it support security features like VPNs, ZBF, IOS Firewall, NBAR and IP SLA for ISP redundancy? Also if my boss will choose chipper Cisco router 881-SEC-K9. Will I be able to organize 2 ISP redundancy on 4 LAN switch port inside VLAN interfaces because there is only one WAN port?

What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.

Cisco Switching/Routing :: 861 As Main Gateway To Ethernet From ISPs Modem?

Oct 8, 2012

I am moving a very small branch office to a new location, but we have a centrally controlled IT infrastructure team in Europe. I would like to implement a hosted VOIP solution without impacting the current network setup (i.e., VPN/Firewall) or asking this IT team to change anything on the existing LAN Network except the IP address/gateway. The VOIP system will have its own cabling.
 
Here is the configuration I would like:
•          Cisco 861 as main gateway to the Ethernet from the ISP’s modem
•          2 static public IPs from the ISP, one for the VOIP network and one for the LAN
•          Cisco 861 acting as NAT/DHCP for the VOIP system on one static public IP
•          My company’s Juniper device on the second static public IP managing NAT for the LAN
 
I have a diagram here to map out what I am considering:
 
Two options I have seen:
 
•          Setup Proxy ARP on the Cisco router, allowing the Juniper device a transparent (and unsecured/firewalled) route to the internet to get the Public IP and manage the LAN (seen in picture)

• Install an additional switch (with proper QOS prioritizing VOIP) at main entry point of location, and have both routers behind this (to minimize configuration of the Cisco router).
