Cisco Firewall :: ASA5510 With Dual ISPs And Static NAT On Backup

Dec 12, 2012

Looking to have an ASA5510 with two internet feeds. Moreover, I would like to have my static nat translations continue to work on the backup feed. I have outbound nat working, however I cannot get the inbound nat to work. I had this all figured out in 7.x but now with 8.x I cannot seem to get it working. If anyone has a 8.x example config.

Cisco Firewall :: ASA5510 Dual ISP And VPN On Backup

Dec 19, 2012

ASA5510 ios v8.4.I've setup dual ISPs and I'm trying to get ipsec VPN client access to work on the backup interface (outside-backup). The goal is to have outbound traffic on the inside subnet NAT'd through the main interface (outside) while inbound ipsec VPN clients connect and operate off of outside-backup.crypto map is applied to 'interface outside-backup,' however clients are unable to connect. If I switch the default route to go through outside-backup everything starts to work again.

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 :: ASA5510 Version 8.4 Using 2 ISPs As Fail Over

Aug 9, 2011

I have a Cisco ASA 5510 and I am trying to set it up to be able to have it failover to the 2nd ISP connection if the 1st one ever went down.  I think I need a nat statement that the "backup" connection will use when the 1st connection goes down, but I am unsure what the nat statement is supposed to be.  I have added the commands that I am pretty sure that I need to add for the "backup" ISP connection.  Attached are those commands, the interfaces that are set up, and the objects that are set up in the ASA.

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 :: 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 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 :: 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.

We got 2 ISPs -------> two ASA 5520 Primary / secondary --------> LAN . ASA is configured with ACL and Static NAT for our mail , web & ftp servers .
 
My question is how to configure the 2nd ISP on the ASA to auto switch to the 2nd ISP when the 1st is down with a backup static NAT and backup ACL for the new ISP , in other words how to configure a active static NAT and Backup Static NAT and ACL only for Exchange/Mail Server.Here is the example of our configuration where PIE is Primary ISP & EMC is Backup ISP.

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?

Cisco Firewall :: ASA5510 Static Routes For Management Interface Not Working

Mar 30, 2011

We have several pairs of ASA5510s in failover A/P mode, some running 8.3(2) and others running 8.4(1).
 
e0/0 = outside
e0/1 = inside
m0/0 = management
 
The problem we're having is we can't get anything to route out of the management interface unless we put in a static route at least to the subnet level. For example, we want syslog traffic to exit out m0/0 to our syslog server 10.71.211.79. Our 'gateway of last resort' points to the next hop out e0/0, and a second static route with a higher metric and a more distinct network space is for m0/0 as in:
 
route outside 0.0.0.0 0.0.0.0 192.168.49.129 1route management 10.72.0.0 255.255.0.0 10.72.232.94 10
 
This doesn't work, and ASDM loggin gives this error: ".....Routing failed to locate next hop for udp from NP Identity Ifc:10.72.232.89/514 to management:10.72.211.79/514"
 
If I put in a more granular subnet route, or a host route of the syslog server it works, such as:
 
route management 10.72.211.0 255.255.255.0 10.72.232.94 10   <------------- this works
 
route management 10.72.211.79 255.255.255.255 10.72.232.94 10   <------------- this works too
 
Why won't a static route for 10.71.0.0 255.255.0.0 work in this case?
 
We are going to have numerous hosts access and be sent messages though the management interface of these ASAs, and it would be very burdonsome to have to add a host, or even a subnet, route for every one. I've removed all static routes and tried to rely on EIGRP, but that doesn't work. I also had to put 'passive-interface management' under the EIGRP for this to work.
 
Here is the pertinant ASA config concerning syslog, routing, and interfaces:
 
interface Ethernet0/0 nameif outside security-level 0 ip address 192.168.49.140 255.255.255.128 standby 192.168.49.141 !interface Ethernet0/1 nameif inside security-level 100 ip address xxx.xxx.xxx.xxx 255.255.255.128 standby

Cisco Firewall :: Create Static PAT To Allow Host Address To Access Network Through ASA5510

The old syntax that I am much more familiar with has been deprecated.  On older IOS it would have been something like static (inside,outside) tcp 209.114.146.122 14033 192.168.30.69 1433 netmask 255.255.255.255  Plus an extended ACL to allow the traffic.I am trying to create a Static PAT to allow a host address to access our Network through an ASA.  I have external address 209.114.146.122 that I want to hit the external interface on an obscure port (say 14033) and translate that traffic to an internal host address on  port 1433.

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

2.   Cisco 2800 router
3.   Cisco 3750 switch

I've finished a part of the configs on above equipments, please refer to the attached diagram.And I'm making a test in order to achieve the below features:

1. By default, packets from PC1 go out through ISP 1. Packets from PC2 go out through ISP 2
2. When ISP 1 is down, packets from PC1 changed its way to ISP 2 through the 2800 router. And when ISP 2 is down, Packets from PC2 changed its way to ISP 1 through ASA 5510.

Cisco WAN :: 877 / 2800 - Use Static ADSL As Backup Connection

May 3, 2011

We have a few WAN connecting sites to ISP using BGP. we are looking at getting backup link for 1 site.

We have decide to use an IP WAN ADS L link. we will have 877 and 2800 for each link. from understanding, we have a static routing on IPWAN service. means when both BGP WAN and IP WAN connected to the ISP. ISP will use ADSL as primary ignore the BGP link. so other sites will see a BGP route coming from ISP via the ADSL link for this location.
 
So we have find a manuel solution, leave ADSL unplugged of power but setup same LAN ip address and connect the cable towards the core switch. when WAN link fail, switch on ADSL. So the static route will advertise to the rest of sites. 
 
just want to know is there any auto solution can disable the ADSL link/ ppp link when the 2800/WAN route is up. and enable the ADSL port when the WAN is down. not sure if HSRP/backup interface/tracking will work? and how?
 
site office switch - > 2800  - >  ISP  - > ADSL ->  ISP 
(need this link to be backup and protocol down, so the ISP will not able to connect to this link and advertise as next hop)
