Cisco VPN :: ASA5505 - Dual ISP And VPN
Nov 17, 2011
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 5.5.5.5, my internal network is 192.168.2.x and my other ISP is 6.6.6.6 - is it possible to use the ASA to accept VPN clients from both ISP's and use the internal network?

I have problem with dual ISP + IPSEC on my cisco ASA5505 sec plus licence.Routing is working correct (connect to Internet from siteA is working trought 1st also second ISP) but IPSEC is working just trought the first ISP! It seemt that phase 1 and 2 of IPSEC is correct but packets are just encrypting but not decrypting.
I'm trying ping from siteA (PC - 10.4.1.66) to siteB (PC - 10.3.128.50)
config site A:
##########################################################################
ASA5505 Version 8.2(1)
interface Vlan1
nameif inside
security-level 100
ip address 10.4.1.65 255.255.255.248
!
interface Vlan2

for the purpose of a redundency, incase the primary ISP goes down the backup kicks in.Can this be done with the basic license (max 3 vlans) or you need to have the security plus license. (20 vlans) Currently not using the 3rd vlan (dmz)

I have two ISP's and I want to channel specific traffic out of an interface based on traffic type. Will the ASA 5505 security bundle allow me to route specific traffic out through a specific interface?

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.

I have setup an ASA5505 running 8.2 with dual ISP's
Primary link is the current live static route out and the backup picks up if the primary fails. That all works great However I have an issue with inbound NAT rules
I have configured an inbound static on the primary which works great
static (inside,primary) *.*.*.* 10.1.1.1 netmask 255.255.255.255 access-list outside_access_in line 2 extended permit tcp any host *.*.*.* eq 3389 (hitcnt=4)
Question? With the primary link active and the default route pointing out through the primary, am I able to configure an inbound NAT to the same inside host 10.1.1.1
on the backup link?
If the primary fails users will need to be able to connect inbound to this service
When I try to set it up I got this error ERROR: Static PAT using the interface requires the use of the 'interface' keyword instead of the interface IP address
So I tried that and got this error WARNING: All traffic destined to the IP address of the backup interface is being redirected. WARNING: Users will not be able to access any service enabled on the backup interface.
So what is the best practice for configuring inbound NAT for a dual ISP configured ASA

I'm trying to set up a S2S VPN between two ASA5505 SP units running ASA Version 8.2(1). I've ordered additional ADSL2 lines to handle this traffic and I'm having troubles with the configuration for the additional PPPoE connection. Here is are extracts from my current config; First the interface vlans
!
interface Vlan1
nameif inside
security-level 100
ip address 192.168.1.1 255.255.255.0
[code]....
The result being that I can ping the OUTSIDE interface, but get no reply from the VPN interface. I've checked ADSL lines, they are up. The two PPPoE sessions are logged in and active. I can even see the ICMP packets hit the VPN interface, but there is no reply.

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.

We are pulled the plug on our PIX 501 as its not letting us use all 100Mbit that our cable provider is now piping to us. I read the conversion guide but it made no mention of the 501's. Only the 515's or newer.The ASA5505 is putting up a little bit of a fight (This what I get for failing my CCNA??)After refusing to configure the LAN ip address to something other than what it was shipped with, I broke down and connected to the management console and forced an IP address on the LAN side. Now I reset my default config and everyone can get on the internet.Until the ISP cuts you off because you forgot to set your static IP. Oh, and by the way, they dont support Cisco gear.
When I attempt to assign the IP to the outside interface, it accepts without a hitch, but everything grinds to a halt. I cannot have this, as I have off-site users that operate with dedicated ports using Remote Desktop. I've attempted to set the IP via both ASDM and management console. I've tried setting a static route, but that doesnt give me any love either. Im running ASA Version 8.2(1) and ASDM Version 6.2(1)Once I get the static IP set and working properly, I can tackle moving the port configs.

Our client has a vendor who needs to establish a VPN tunnel to their own router which sits behind our Firewall.
VPN Concentrator (Vendor) <------> ASA5505 Client (7.2) <-------> 3750 Switch <-------> VPN ASA outside Interface - 208.64.1x.x4 DG - 208.64.1x.x3
ASA Inside Interface - 172.20.58.13/30
3750 Switch Interface Connected to ASA - 172.20.58.14/30 and DG - 172.20.58.13
3750 Switch Interface connected to VPN router - 172.20.58.21
VPN Router Interface connected to the 3750 - 172.20.58.22/30 DG - 172.20.58.21
I have also attached a Visio for this and the running configuration from the ASA and 3750. We don't have access to the TNS VPN router. Our responsibility is to just to make sure the tunnel comes up.
1) Create a static NAT on the ASA for Public to Private IP of the VPN router
Public - 208.64.1x.x5 / 28
Private - 172.20.58.21 / 30
Will the ASA automatically ARP for this address or do i have to configure another interface on the ASA with this public IP?
2) What would the access list look like on the ASA?
3) The client gave us some config to copy the stuff on the ASA so that they can create the tunnel but i couldn't put those commands in the ASA. How would this be applied and on what interface?
Firewall Access: The following information pertains to access between the VPN router and the
VPN concentrator. If a firewall/router is present in front of the VPN the following services need to be
allowed:
permit esp host 208.224.x.x any
permit gre host 208.224.x.x any
permit udp host 208.224.x.x any eq isakmp
permit udp host 208.224.x.x any eq non500-isakmp(code )

We have multiple servers on the DMZ (192.168.2.0/24) but they cannot access any resources in the Inside, by default. We would like to open up a Syslog server from the Inside (10.1.1.5) to the DMZ servers, so we can collect system log from the servers.

I have 4 remote sites that are using a ASA as thir firewall / router. I'm setting up a full mesh VPN between all the sites. One of the sites have a UC500 and the other sites access that UC over the VPN tunnels. I would like to set up some basic QoS for the VOIP traffic
The site that has the UC will have multiple vpn tunnles coming in from the remote sites. How will I do QoS with voice traffic on that site?

I have 2 office buildings using Cisco 800 series routers with a L2L VPN between both. I'm upgrading the router to an ASA5505 at one of the offices but can't figure out the L2L VPN on the ASA. Specifically, can't figure out how to set the pre-shared key. On the Cisco 800 it's:That doesn't seem to work on the ASA. Here is my current config on the Cisco 800. [code]

I need to create second VPN in same ASA5505, it has already a VPN to one of our clients. So it alredy have a transformset,cryptomap,policy.Now i need to create new one. i like to create a seperate transformset and crypto map for this 2nd VPN with a new name to identfy very easily.But i have doubt like may it will affect the current VPN? because it has another VPN with another tranformset and cryptomap.......
1) will it affect the current VPN?
2) do i need to create a seperate tranformset and cryptomap? or with same tranformset and cryptomap with different number.....if it possible to create multiple cryptomap then i would like that to create.....

My company purchased a PAK for ASA5505-SEC-PL a while back. I found it unopened and need to know if it can be used, without activating it on an ASA. I opened up a case with the Cisco TAC, provided them the PAK serial number and got the following responses from 2 different individuals:
1.Since the product was covered under warranty and then expired this means that the activation key was used before.
2. This PAK number is expired since (Warranty End Date 21-Feb-2009).
I responded that I am not interested in warranty information but I just want to know if the PAK can be used. Just because the warranty expired, does that REALLY mean the PAK can no longer be used? That doesnt make sense to me. Isn't there a tool on Cisco's website to put in the PAK S/N to see if it is available, has been used, and if so, when?

I have 2 x ASA 5505's , I would like one to sit at my office behind an ADSL router with a static IP address, and be configured as a Server. I would like the other to connect to an ADSL router with a dynamic IP address, and be configured as a Client.
This must be a plug & play setup, so that when the 5505 client is plugged into ANY broadband router, it automatically creates a VPN tunnel to the 5505 server. Incase it's relevant... the purpose of this link will be to stream video data back to my office from remote locations. We have "played" around with the ASDM, EasyVPN and wizzards and still cannot get this to work!

I set up a full mesh LAN-to-LAN VPN for a client with 4 sites. Each site has an ASA 5505 running 8.2(5). Site-to-site VoIP traffic runs in the VPN tunnels, as well as traffic to/from a file-server located at the main site. There are two back-up servers, one at the main site and one at a remote site. The main site has 2 bonded T1s and the other three sites have a single T1. How should I go about setting up my QoS?
My top requirement is that VoIP traffic will never be pushed out of the way for data traffic. My secondary consideration is to give more preference to file-server traffic than to web traffic and to make back-up traffic the least important. I'm currently researching to see if the VoIP provider is DSCP marking EF on the VoIP traffic, but I am going to assume they are for now. I know the IP of the file-server and back-up servers.

I have two ASA 5505 on two different locations(main office and remote office) and I need the remote office to be in the same subnet as the main office since they move computers betweend the offices and they have fixed IP addresses on those computers and they have no right to cahnge to dhcp mode when they move to remore office. Is it possible to create like a bridge over the VPN tunnel so it extens the LAN ?

Is it possible to use IP "aliases" on an ASA5505 to use as static NAT public IPs to private IPs? For example, I have int e0/0 connected to my ISP using a /30 subnet and I have my private LAN connected to e0/1 with a /24 subnet. At the moment I can use the one usable IP from the /30 to NAT to the private LAN. The ISP is also routing a /28 subnet to the one public IP of the ASA. I would like to use some of the /28 IPs for NAT also. Can it be as easy as just adding the NAT commands? I figure I would have to add that subnet to the ASA somehow, no? In other devices (including the SA520) they use a concept called IP aliases whereby you define what additional IPs the device can use in its NAT config. Does the ASA support aliases? Maybe I have to do something with VLANs?

I have set up a IPsec L2L VPN between a ASA5510 and a ASA5505 which is working just fine.Every now and then our management station receives the following syslog message: Session disconnected. Session Type: IPsec, Duration: 2h:23m:23s, Bytes xmt: 3283338, Bytes rcv: 8637607, Reason: Phase 2 Error.I have already searched the forum for this message to exclude all the possible reasons for this message:
- the complete crypto maps are the same on both ends (lifetime, psk, pfs etc)
- the ACL's used in the crypto maps are exactly the opposite of each other

I have 1 network that I'm trying to make secure, and it needs to access 2 seperate networks. I tried using an ASA5505 that I had on the shelf to accomplish this but discovered that I had the basic license and that was prohibiting me from getting my connection to my 3rd network. I scrapped that idea and grabbed an old pix 501 off the shelf to bring my connectivity to my 3rd network online since the 3rd network is only passing ip traffic to a small group of servers on the outside I figure the 501 should be just fine.
So, here's the problem I am running into:My internal network is 10.10.16.0/16, I have a new domain controller with DHCP on it handing out addresses in the 10.10.16.0/24 range.External Network 1 is 192.168.16.0/24. The services I need from that network are primarily in 192.168.0.0 range, however there is a comcast router 75.123.123.123 (Changed of course) that provides high speed internet I need for my www traffic.External Network 2 is 10.1.1.0/16 I have about 4 servers I need to access on this network and that's it. This network has it's own domain and DHCP controller and I've been given a range of ip's to use on this network of 10.1.3.180-10.1.3.189 My switch is just a plane jane 3com switch with minimal management so I am attempting to use my ASA5505 to handle my layer 3 routing.
So here's my issue:ASA5505 (IN:10.10.16.1, OUT: 192.168.16.6): Passes traffic to External Network 1 and to the comcast router, no problem. All my computers on my 10.10.16.0/16 network have access to everything on 192.168.0.0/24 as well as getting full name resolution and www traffic across the comcast router. Can NOT access 10.1.1.0/16 no matter what. From inside the ASA or from on the inside LAN ports. It CAN ping the PIX 501 PIX 501 (IN:10.10.16.3, OUT: 10.1.3.180) Can ping EVERYTHING. Can ping 192.168.0.0/24, can ping 10.10.16.0/16 and can ping 10.1.1.0/16. Set to globally assign the other IP's in my range as addresses for outgoing traffic.Workstations (IN: 10.10.16.XXX DHCP, using 10.10.16.1 as gateway) Can only access everything on External Network 1. ZERO access to External Network 2. ATM I have both INSIDE and OUTSIDE ACL's wide open for both firewalls just to get connectivity going. I will be tightening it up after it is operational.Attached find a log file (Sensetive data removed of course) that contains the sh run and sh ver for both the ASA5505 and the PIX 501.
