Cisco Firewall :: 5585x - Multiple ISPs Plus WAN And DMZ
Aug 17, 2011
Looking to replace an "all-in-one" type firewall (UTM/Firewall, SSL VPN) with a cisco product - the issue i'm running into is that we have multiple ISPs plus WAN and DMZ - overall more than 5 ports on mid-range ASA devices - and from what i read, adding 4-port module precludes me from adding CSC module.
Is there an solution to that other than going for 5585-x model? (kind of over our budget, granted we need 2 for failover)

Friend of mine has a setup out in the sticks, currently with two ISPs: Hughesnet satellite, and a line-of-sight WiFi provider; they're also getting a cel tower within range soon and he's looking at adding an HSPA/LTE connection via that as well.the first gives him a static IP and ridiculous speed and bandwidth at night... but far less speed and a painfully low bandwidth cap during the day (you go over, you pay through the nose).
The second gives lots of bandwidth but poor speeds (difficult to even watch a YouTube video) and a constantly-changing dynamic IP.The third, once implemented, will give him good speeds and decent bandwidth (I believe up to 10GB/mo) but again, will get spendy if he goes over that limit.Right now, I've got him set up with both routers plugged into the same network, multi-homed the NICs on his machines (192.168.0.* for Hughes, 192.168.1.* for LOS) and a little script on each computer that will change the default gateway to let him select which ISP he wants to use... however, it's going to get trickier with a third, and will make it even tougher to keep track of the bandwidth used on each one... especially with multiple computers, a DVR, and two users.
So I'm looking for some way to automate all this... something that will, say, use the HSPA feed most of the time for his whole home network, switch to LOS if it gets near the cap, and switch everything over to the satellite automatically during "unlimited" hours. Again, I'm not opposed to setting up something PC-based with the appropriate software, although for my own sanity, it would really need to be Windows-based (I'm way below n00b with Linux).

what you're doing to load balanace internet traffic? I'm interested in load balancing internet traffic (outbound -AND- INBOUND) using multiple (at least 2) ISPs. Some of the methods I have used in the past have certain weaknesses.. basic DNS load balancer (relies on multiple IP addresses per host), OER/PFR (ability to control INbound is limited unless complex configuration and coopearation with ISPs)... This is kind of a broad open ended question.. It seems like something that would be a common issue and am wondering what other are doing with the capabilities 2800, 2900, 3800, 3900 series routers..

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).

Looking for a recommended code on the ASA 5585x firewall. We ran into a bug (CSCtr24705) on version 8.4.2 where it rebooted the primary firewall. The bug has to do with modifying an existing ACL that's part of a custom policy-map inside a service-policy. If we upgrade to 8.4.5 (which has the previous bug fix in it), there is another major bug (CSCud70273) where if you use the packet-tracer input command on an inside interface it causes problems too.
I don't understand why packet-tracer input would have a bug associated with it when it's been around for a long time and we use it on a daily basis for troubleshooting. Is there stable code for the 5585x to upgrade to without running into possibly a major bug? This is our core firewall so there are no VPN tunnels on it. It's setup in active/standby failover in routed mode.

I have a circuit that will be delivered to a client next week and we are installing an ASA 5585x for them. They will have a circuit coming in with a few VLANs configured on it. One VLAN for the Internet and one for connectivity to another client.
So does the ASA allow you to create the "outside" interface on a subinterface?

I will be supporting a new ASA 5585X running 8.4 and I was wondering if it's possible to apply an ACL globally instead of it as an access group that is applied to a specific interface as in or out ... below are the interfaces and ACl.

I have a active-active setup with 2 cisco asa 5585x running 8.4 - the boxes ahve each 2 sec context's build-in - which gives 4 sec context in the cluster. I have 2 x 5 extra licenses (2 x ASA5500-SC-5) which I haven't applied yet - will this give me a total of 10 or 14 security contextes? I am a bit in doubt because if I only get 10 sec contextes in this cluster then could I instead get a single 10 security context license (1 x ASA5500-SC-10) and add this - hereby I would get 12 then.

I want to configure 5585x Active/Standby with 2 nexus switches utilizing VPC technology. New ASA 8.4 supports etherchannel so I want to plugin 2 cables from ASA1 to sw1 and sw2 and 2 cables from ASA2 to sw1 and sw2? Is this a valid design? how would I configure that? Any design document on that?

I have an asa 5585x cluster. I get ssh access but no console access on the standby unit.
On the active unit, when I try console access, ASA ask for a password. I have tried all the one that I have configured, but without success.

We have a 5585X running in multi context mode, and we are getting log entries for scanning threat detection, such as:
%ASA-4-733100: [ Scanning] drop rate-1 exceeded. Current burst rate is 2 per second, max configured rate is 10; Current average rate is 5 per second, max configured rate is 5; Cumulative total count is 3116
Threat detection is not supported in multi context mode so I cannot tune the thresholds, is there any way that I can get rid of this outside of messing about with logging levels/message IDs?

Currently we have a T1 for data connected to a 1721 Router that is connected to an ASA 5510. We would like to add a FIOS line for dedicated online backup. Is it possible to connect the FIOS router to the ASA and route the IP from our backup server to use the FIOS line and everyone else continue to use the T1?

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?

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?

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.

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.

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

I am looking at deploying a pair of 5585X's in an active/active multiple context state. I am creating Mulitple contexts that need to be able to route to each other. I was going to deploy a type of Gateway context that has a shared interface to all of the other contexts, instead of sharing interfaces directly between the contexts, i beleive this will work as basically i am just cascadng the contexts and sharing interfaces.
The main problem i have come across, is that if i deploy active/active across two appliances using 2 failover groups i can not see a way to route between them, for example.
I have Context 1, Context 2 and Context GW A including the shared interfaces of Con1 and Con2 in failover group 1 on appliance A with the respective standbys on Appliance 2. I have Context 2, Context 4 and Context GW B including the shared interfaces of Con 3 and Con 4 in failover group 2 on appliance B with the respective standbys on Appliance 1.
I need to be able to route traffic between Context GW A and GW B so that the contexts can communicate in normal operation and in failover. I do not beleive that I can share an interface between contexts in two separate failover groups and to be honest without adding a L3 device between the appliances i am not sure if this is possible.

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.

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.

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.

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.

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

Lately I encountered random Internet connection issues?My router is a Netgear Wireless ADSL Firewall Modem Router DG834 (Firmware V1.05.0) and my ISP, isn't the most reliable regarding bandwidth... All clients (max 3 at the same time) connect wireless.The problem is that the last few weeks my connections is very unstable, all clients lose the internet connection until you restart the router manually.I can't even connect to the webinterface (192.168.0.1), during the downtimes.

I'd like to add an RDP to the vpn portal page on our 5585x. Looking for the rdp plugin in the 5585x download area but there is no page for Remote access plugins. Would the plugin be the same as any of the 5500 ASAs? Could I just download the rdp_09.11.2012.jar file from the 5505 download area?

Starting a project where they customer has ASA 5585X with SSP40 with 10K SSL Premium Lic and ACS5.1.The cust wants IPSec, and Anyconnect Client terminations. The number of users will be close to 6000 and will scale.Due to the huge scale of users, i am not able to finalize a design. Have the following doubts.
1. Will ACS have any issues in supporting a database this huge. OR is it better to go with the AD/LDAP integration.
2. What is the best way to allocation IP address. Does ACS 5.1 support dynamic allocation form an IP pool.
I have been browsing through the forum, couldnt find anything concrete.
