I have Cisco ASA 5520 . I want to deploy this in the following scenario. Two ISP( for internet) links are connected in the ASA. Three zone ( Outside , DMZ , Inside) specified on the ASA.In DMZ , there are two proxy server ( proxy 1 , proxy 2) . Branch user will use proxy server 1 and Head office will use proxy 2.
In the above scenario management requirements are, Proxy 1 will use ISP 1 and proxy 2 will use ISP 2.If ISP 1 goes down then proxy 1 will use ISP 2 for internet. Please suggest me how I will configure the ASA in the above requirements or if possible send me the configuration.
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.
I have a client that is requesting redundant internet connections using 2 7204 routers to 2 asa 5520 in an active standby configuration. There is no load balancing requirement this is strictly for failover. The issue that I am having is that I have to have 1 of there public IP addresses on the Lan side of the 7204 for the ASA connectivity. Because of this both routers advertise out their public subnet to the respective providers, but the issue is that when the wan link on the primary router fails and traffic traverses the secondary wan the return traffic comes back in the secondary wan and stops because it sees the link to the asa as being up even though the asa is in standby. No matter what route manipulations I do a directly connected route is alway going to be better. How I can get this to work. Below is a rough sketch:
Verizon------Router A (Primary)-----ASA A (Active)--------------Nexus1 | | | | IBGP | Keepalive | VPC Link | | | AT&T---------Router B (Backup)-----ASA B (Standby)------------Nexus2
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.
Not sure if my subject is a good decription of the problem or not.
I have an ASA 5520 at my home office and a SonicWALL NSA2400 at my remote office. The remote office has dual internet connections and I wanted to create two seperate VPNs between the devices using each internet connection on the SonicWALL.
I know how to configure this on the SonicWALL, the problem is on the ASA 5520
OK Basic network config
ASA Public IP 184.108.40.206
ASA Internal network 192.168.1.0 (VPN source)
Public IP 1 220.127.116.11
Public IP 2 18.104.22.168
Iternal network 192.168.2.0 (VPN destination on ASA)
If I have a VPN from the main ASA to either one of the SonicWALL's public IPs everything works fine
If I create 2 VPN tounels from the main ASA, 1 to each public IP on the SonicWALL, the VPN shows as up but no traffic flows.
I recently configured WCCP with a Sophos Web Filter on my network it works good but the problem I am having is I have two 5520s so I am directing the device to look at 2 different IP addresses and since the devices are in an Active/Passive failover. The problem is because the second device is in a passive failover it is not responding which is throwing connection errors to my Sophos device. I know you can have a single management connection for the ASA's but is there a way to have a single IP for the ASAs for the WCCP?
We are looking to deploy an ASA 5520, but I need to know if it is possible for it to work in this environment.
We have colo space, with two IP ranges. They provide two network drops, one from each switch connected to different routers. One in which has 4 usable IP's for management purposes. This address range will be used only for remote access to the ASA and VPN into the management VLAN. The management VLAN will have all internal devices such as the switches, etc. The second range is for the servers, of which will be assigned directly to the hosts and the ASA will need to act as just a firewall. I can do this on IOS, but not sure about the ASA.
I need to answer the following questions:
Does the ASA support dual network drops, and would this be a failover port configuration in order for it to work?A management VLAN with outbound internet access only, and VPN/RA capability. NAT will need to be used I'm guessing. Can we have a DMZ VLAN which has defined ports, say 80, 443 and 25 inbound and outbound. I need the hosts to have the public IP assigned to them with no NAT configuration.
I know there are some advantaged to using NAT, but I really can't use it because the applications behind prefer public IP's being assigned to them.
I need to move the client machines off of the 3750 (and their DHCP dependency on it) to the SGE2010 and absolutely route their internet traffic out through the outside interface on the 5505. They must also be able to communicate back into the internal environment in order to communicate with the production servers.
The clients currently use .254 addressing through a dumb dell switch to the 3750 but I am trying to migrate them over slowly to the .253. I know that the 2010 will not do DHCP, so I am putting a DHCP server on that switch right now. The 5505 won't let me add an additional nameif statement onto one of the other eth0/x interfaces and I'm not sure if that has anything to do with it's capabilities to act as a DHCP server (it's not an option in the ASDM) or it's ability to serve as the internet gateway for the 2010 clients. (Side notes: The 5505 has a base license and is currently also connecting 1 site to site VPN. As is the 5520, so all of it's interfaces are used as well).
I statically assigned a moved client with a .253 address and plugged it into the 2010. I have tried giving the 2010 both a .4 address and a .253 address but neither will allow me to ping any of the addresses on the 5505. The 2010 shows automatic routes to the two subnets and I set it's default route to 253.1. The link between the 2010 and the 3750 works - clients receive a .254 address from the 3750 and can get out to the internet via the 5505 and reach the production servers as well.
Why won't the 2010 see the 5505 as a gateway and allow clients to get to the internet and also traverse the 3750 when they need access to the production network?
The reason why I dont' just connect the two swtiches and call it a day is because I also need the production servers to ALWAYS go out/receive web requests via the 5520 outbound/outside interface. I'm having such a hard time wrapping my head around why i can't get my clients moved over to the new switch, I haven't even grasped how I'm going to do that yet.
I have the following: 1 5520 ASA connected to the internet, 2 core switches, and several access switches.Aside from implementing RSTP, VRRP, hard code access and trunk ports, is there any other recommendation you would like to add.
I would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them.What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. 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.
how to change our wireless setup. Currently, we have 2 Cisco AiroNet 1130 WAP's in the office that go directly into the 2 POE ports on our Cisco ASA 5500. These WAP's have 1 SSID and are using WEP for security. After demonstrating the flaws of WEP to my boss, he has agreed that we should use something more secure and I've suggested WPA. We want visitors to our office to be able to hop on our wireless but on a separate guest SSID with WEP.
I'd like the internal SSID to route to the ASA and take the default route to the internet (it will be our new fiber connection once it's installed in a couple weeks). The default route is whichever connection is working since our ASA 5500 will fail over when it detects an outage.
I'd like the guest SSID to route to the ASA and then go over our existing cable connection. This connection will be our backup once the fiber connection is installed. Since we won't be using it very often, but will be paying for it, I advised that we send all guest wireless traffic over this connection since 50/5 is plenty for guests.
The current SSID (which will be the internal SSID) has no VLAN. We do currently have a few VLANS on our network, one for voice (.42) and one for data (.100) and the default (.0). What device to I create the VLAN on (Cisco 5500?) and how to I setup the WAP? I need very basic instructions to start and I'm also trying to do this without causing downtime if possible.
I've attached a diagram of what it should look like. Red indicates our internal network and Blue indicates the guest network. I can send screenshots as well.
I wanted to ask a question about the diagram I have included. We are bringing up 2 MPLS WAN connections and would like some specifics on the best design. We are using BGP to the providers. From there we have big questions. We can run BGP internal and are licensed to do so on the N5K's. The N5Ks are currently using HSRP for inside LAN clients as default gateway. We want to load balance and provide redundant routes using a dynamic approach. Should we use BGP internal utilizing the connections between the routers? Should we use HSRP on the routers? How best to get the routes to the N5K and should we be considering this?
I run 2 RV042 V1 for home and office with Gateway to Gateway VPN connection with single WAN connection in use. Everything works like a charm!
I was even able to create VPN connection with 2 WAN connection on one Router and 1 WAN connection on another with Smart link failover and VPN Tunel Backup.
I got problem though when i tried more complex connection diagram. [URL]
So basically I now have 2 ISP connections on each point with Static IPs and I'd like VPN Connection to be alive for ALL 4 options automatically with failovers (smart links) And tunel backups but i'm not sure if that's ever possible with my equipment.
Basically, he has an office he's supporting on a contract basis, they have a cable modem uplink. They move very large (100MB or so) EXCEL files to/from a server "somewhere out there"...The place has 19 users on cable modem (presumably commercial level). They're having "severe latency due to all the users". They're also using VOIP (not sure what product, shouldn't really matter)this doesn't pass the sniff test to me- I have 70+ users on 4 T1s and don't have the problems they claim to be having. Suspect they should be doing some packet sniffing to see who's camping on Youtube, but this is not an option....They're adding in a second cable modem line and want to bind both together. I immediately figured they should do QOS, dedicate the mission-critical traffic to 1 line and let it bleed over onto the other and take precedence if necessary. They have a Cisco 1811 router. I haven't messed with those before, but what I am seeing is they are a "fixed-configuration router". Obviously there has to be SOME config changeable- if for nothing other than IP assignment to interface and such. So what does Cisco mean by "fixed-config"? Is this basically a dumbed-down Linksys router?
The basic setup Newly installed redundant ISP, thus setting up the 891 with dual WAN Using PFR to load balance between the two. Did initial config through CCP (not express), but I am familiar with the basics of IOS CLI (not used to the new zone based firewall yet, managed aour old Pix for too long, but that is a different subject)
I cannot seem to get anything but Gi0 to be accepted as a WAN interface. I go through the entire setup in CCP, test each connection, etc, and it all looks good until I exit out of CCP and go back in. At that point, I get squat out of Fa8. CCP won't let me test the connection, won't let me edit the connection, wont let me delete the connection. The wizard for a new WAN connection becomes available again (Wanting to set up a "second" WAN on Fa7...)
Again, I have verified connections to each ISP line independently, either one works just fine on Gi0, neither ever works on Fa8. This is my first real foray into PfR.

I would like to configure my Cisco 881 enabling Dual Wan (load balancing and failover). First link: HTTP, FTP, SMTP,...Second link: DATA inter-site (VPN), VoIP,Does the configuration seem OK?What does the command line "track 1 rtr 1 reachability delay down 1 up 1" mean?To send the different flow on one or the other port, do i have to configure it on the ACL1 and ACL2 ?
I have an ASA 5505 with the Security License running 8.4 and 6.4.5 software, I have a fully working VPN solution on there using a ISP IP - works fine. My boss wants to split the lines/bandwidth to another ISP we have coming into the office. So what I want to acheieve if possible is this Say my current isp is 22.214.171.124, my internal network is 192.168.2.x and my other ISP is 126.96.36.199 - is it possible to use the ASA to accept VPN clients from both ISP's and use the internal network?
At the moment I'm running a T1 to a Cisco ASA 5505 device. I'm in the process of getting a backup ISP. My question is, is it possible to configure this firewall with two ISPs so that the same internal webserver can be accessed via backup ISP?
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?
i have two branch offices A & B both connected by a vpn. i am planning to add another isp on both the locations and have it just for the vpn. i.e have the second isp do just vpn and all other traffic go through the older ISP.. what are my options ? am not planning to add any extra hardware and also am not planning on acheiving any fail-over or load-balancing because i know ASA 5510 does not do load-balancing.
I have a DMVPN network with 2 hubs (2821's). This setup is used for VoIP applications over the Internet for teleworkers. At the main hub site I used to have only 1 Internet feed which was DSL with a static IP. Now I have 2 WAN feeds for this site - 1 FTTB w/ PPPoE & the DSL with static IP. Since this site also hosts a PRI, I want all voice communications to go through the FTTB link instead of the DSL for obvious reasons, but keep the DSL as DMVPN Hub for all NHRP lookups as this link has a static IP address & is very stable. We originally put the PRI router as a DMVPN spoke which connected through the FTTB link, with another router acting as the DMVPN hub on the DSL link. This was obviously a waste of machinery. I want to combine both routers into one. So I tried something like this (don't laugh):
Gi0/0 to FTTB (Dialer1 connects to Internet) Gi0/1 to DSL (Public IP towards 877 demarc) Tun0 attaches to Dialer1 public IP and connects to other spokes, no VRF Tun1 attaches to Gi0/1 public IP and acts as DMVPN hub (ip nhrp map multicast dynamic) under VRF "Hub"
EIGRP AS 1 is set up twice, once under router eigrp 1, and the other using router eigrp 2 using an address-family under the Hub VRF.This kinda works but obviously Tun0 & Tun1 do not speak to each other. I also had to remove the ip nhrp map instruction that pointed to Hub1 on Tun0, as this was causing a weird condition in the router where it was repeatedly trying to connect a tunnel to itself, and crash the router because the NHRP process would go haywire. So my users must rely on the Hub2 to get a NHRP lookup for the PRI site. If Hub2 goes down, everything works in the network except for tunnel connections to the FTTB link. I'd rather not have to configure 2 tunnels on each spoke router unless I really have to.
First of all i have gateway 2 gateway VPN configuration (both same RV042 with same firmware) + QVNP clients
The first one that i have those lines in my log "Ignoring Vendor ID payload" which doesn't allow clients to be connected from the first time they connect after several retries, or can't connect at all. I've doublechecked ports opened, and 500 is blocked by ISP. Also double checked, tried turning on and of Windows machine firewalls and etc - nothing worked. What would be the solution? should i manage to call my ISP and ask opening the port and it will solve my problem? HTTPS is enabled on router (this one i read in other topic)
The other problem is that one of my routers just stuck and i have manually to turn off, and then to turn on that it would start working as it was. Log files doesn't show anything. Router started to crash after the last Firmware upgrade.
I am trying to create a backup tunnel from an ASA 5505 to a pix 501 in the case of the Main ISP failing. The Pix external side will stay the same, but not quite sure how I can create a new crypto map and have it use the Backup ISP interface without bringing down the main tunnel.
My first thought was to add the following crypto map to the configuration below: [code]
My client is transitioning to a new ISP and want to migrate there web servers in stages. therefore they would like to keep some servers running on the old ISP and some servers use the new ISP.
I have set this up in a lab and keep running into routning issues (I am using 5510 for the lab as I do not have a 5505 available). I know that ASA's don't support PBR. Is there any way or trick to get this to work on the ASA?
I have a feeling this is not possible and we would need to get another ASA or a Router to get this to work.
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.
