Cisco Firewall :: Adding Remote Routers To ASA 5510?
Jun 13, 2012
I am pretty new to Cisco networking and setting up a test router to use from home to connect into our network. My organization would like for us to provide upper management with home office setups to give them the ability to work from home. We will provide all of the equipment of course (router, phone and workstation). my boss wants me to use some of our old decommissioned equipment to set up a test home office to see how efficient and feasible it would be. I have a Cisco 1700 router, Altigen IP720 phone, and Dell Optiplex 380 workstation.

I am adding a failover asa to an a firewall that is already in production. They are both 5510's, they both have the same abount of ram, have the same code versions. Will there be any downtime while adding the secondary in?

I had a working active/passive pair of ASA5510's, and then I had to do a rush firmware upgrade, but didn't have time to do it on the secondary at the same time. Now I have made config changes and upgraded the secondary firmware to be the same, and wish to know if I plug it back in if it will think the secondary has the "correct" config or if it will know that the primary is newer. I disconnected the failover cable because it was complaining about version mismatches constantly.
Is it safe to add the secondary back in or is it possible it will be declared newer and overwrite the config?

I have configured a remote access VPN on my Firewall ASA5510. Everything worked fine and I can successfully connect through the VPN. The problem is I cannot ping or connect to any of my internal network resources. I tried to add a new NAT route from outside to my internal servers using the defined pool but due to a new ASA version there are many changed I see in the NAT routes

I have a cisco ASA 5510 that I have set up currently to access via ASDM through the Inside interface. When I VPN in using our older VPN server I can connect to it fine. I recently set up the ASA to also be a VPN server which will eventually replace the older server for our HQ. I noticed that when I'm VPN using the ASA as the VPN server, I can only ASDM to the public which I prefer not to allow. Access to the inside doesn't seem to work this way. What configurations if any would be causing this. I'm assuming it's some thing I need to adjust in the VPN configuration.

I have a ASA 5510 at our corporate HQ that has one site to site VPN. I need to add 6 additional site to site VPN's to this ASA for our remote branches. How can I add them without affecting the existing site to site VPN? The 6 site to site VPN's will all have the same settings however these settings are different from the existing site to site that I already have set up. How can I set it up so the 6 additional VPN's use their own crypto map and all use the same settings?

I have a customer with active/standby on a pair of 5510's with the CSC modules. They were inquiring about the AIP/ASA, and since this would NOT work in their current setup, would getting a pair of 5510/AIP configured for transparent failover work placed in front fo the existing units? Would I need to have a switch placed between the AIP and CSC ASA's? Or would I setup the ASA's for context based Active/Active failover to interconnect the ASA's to the existing units, but I still see a need for a switch.

We have an inside interface, 192.168.10.0/23We have an outside interface, public ip...We have the ASA connected to 5 site to sites, this is working fine and through the internal interface can access all remote sites and vice vera. These are 192.168.20.0/24, 192.168.30.0/24, 192.168.40.0/24, 192.168.50.0/24 and 192.168.60.0/24,When a user connects via Cisco VPN Client they can see the inside network but can't talk to the remote networks connected, for instance 192.168.40.0/24... whereas an internal user can. I understand that the VPN client connection is seen as an outside connection, not an inside connection... but then I read [URL] and I am confused even more.

I have a Cisco ASA 5510 that was set up as a VPN server for working remote. I have disabled split tunneling so that all traffic created while VPN'd in goes through the ASA. The problem I'm having I believe would be resolved if I enabled split tunneling but I would prefer another solution. Now..for the problem.When a user is connected via VPN, they can hit all intended devices both public and private accept servers that have static NATs in the FW. So Server A has a public of 1.1.1.1 which is one to one mapped to private address of 10.1.1.1. Now if the remote user brings up a browser and goes to 1.1.1.1 it wont work. The FW gives me a error which is posted below. However, using the private IP of the server works. I thought about trying to manipulate DNS to resolve this as the remote users are using URLs and not IPs when trying to reach these servers but again, was hoping I could resolve the NAT problem that the FW seems to be having.
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src Outside:192.168.202.100/49238 dst INSIDE:1.1.1.1/80 denied due to NAT reverse path failure 192.168.202.x/24 is the remote vpn ip given via the ASA.
Here are some configurations on the ASA:
static (INSIDE,Outside) 1.1.1.1 10.1.1.1 netmask 255.255.255.255
access-list INSIDE_nat0_outbound extended permit ip object-group DM_INLINE_NETWORK_2 192.168.202.0 255.255.255.0
object-group network DM_INLINE_NETWORK_2
[code].....
Outside with 4.4.4.4 as the public ip traffic gets NAT'd do dynamically Inside with 10.1.1.x network on it.The ASA is running 8.2

we have a base license ASA 5510, and been trying to get ICMP working to check that we're routing and not hitting any NAT translation. We have a VLAN280 setup to ISP for VPN link to remote site and another VLAN281 for internet access for internal users.
Users can browse internet from (name _inside interface e0/1 access port) which is fine. When I do a ping to remote office through the VPN I get a response pinging from VLAN280 name VPN_Link. When I do a ping from name inside interface I don't get a response both are security level 100 with same-security-traffic permit inter-interface configured.
Config:

I have been tasked with setting up a guest wireless network for a remote office. They would prefer that the guest network be on a different VLAN than the trusted network, and they want to use a different outside IP address for the guest network.
I am trying to figure out how to configure the ASA so that it supports two different LANS, each with it's own outside IP address. Is this possible?

I have a remote VPN with split tunnelling enabled. Currently, users connected to this VPN browses internet with his/her internet connection. Now, my requirement is that a roaming user connecting to the vpn must use our company's internet connection for his browsing purposes. How can I do this?Equipment we are using: ASA 5510

ASA 5510 ASA 8.0 ASDM 6.1 I want some remote users to have split-tunnel connection, others not. I used Cisco Document ID 100936 "Allow Split Tunneling for AnyConnect VPN Client on the ASA Configuration...". I created a new Group Policy with split-tunnel enabled. I created a new Connection Profile and assigned to it the new Group Policy. When I authenticate at the AnyConnect client I get a dropdown of the 2 connecton profiles, to choose the one I want. Each of them works, enabling or disabling split-tunnel. But I want to assign a connection profile to the particular user, not give the user a choice. The problem is I'm using LDAP authentication. The Local Users I set up before LDAP are obsolete, assigning them a Group Policy does nothing. I really don't want to give up LDAP and force people back to another local password. But the LDAP authentication to Active Directory just says yes or no, it won't assign a connection profile. At the AnyConnect Connection Profiles page I have set a switch "Allow user to select connection profile, identified by its alias, on the login page. Otherwise, DefaultWebVPNGroup will be the connection profile". If I clear that switch every user will be assigned the same default profile, which does not work.

How would I go about configuring RADIUS based AAA for remote access VPN users? I have an OSX RADIUS server and an ASA 5510
(I want to keep console and SSH using LOCAL, so I keep this: "aaa authentication ssh console LOCAL", right?)What does the rest of the config look like to get RADIUS based AAA for remote access VPN users?

I'm attempting to configure remote management (and, sometime soon, SNMP) for a newly-deployed WRVS4400N v.2.At the Basic Settings page, I enabled Remote Management, and left the port # at the default. Remotely I entered the public (static) IP for the router in the address bar of IE8 similar to this: 67.203.???.??:8080. IE8's response is, "The webpage cannot be displayed." I'm using a public wi-fi access point, and don't know how the local router is configured, so it's possible that the local router has a blocking rule in the firewall.I'll try again using another remote router that I manage.

I have a RV082.I need to disable the firewall, since firewalling is done better elsewhere.However disabling firewall Remote management on wan ip is forcefully enabled.I don't need Remote management, keeping it enabled is a security risk for my setup.I don't understand the rationale behind the choice to forcefully enable remote management if firewall is disabled.Is there a way to disable both firewall and remote management?Or at least a workaround?
I'm on firmware 2.0.0.19-tm on a probably v2 hardware. (Cannot find this info in the web configuration).This is not the newest even for v2 hw but I cannot afford to break it trying to upgrade the firmware.Moreover no release notes for firmware releases refers to a correction of firewall/remote management behavior.Is this behavior also in newer firmware releases?

Currently I want to add a second lan (vlan) in a customers network. The new network will be for a wireless infrastructure.There is also VPN Configured on the ASA - One with L2TP for Windows Clients and an IPsec for Cisco Clients.Former we only had one outside (Eth0/0) and one inside interface (Eth0/1) on the ASA.Now I want to use the Eth0/2 with subinterfaces, so that we will be flexible for future, when deploying more vlans.But now, when i turn the first subinterface Eth0/2.2 to no-shut the VPN Connections does not work any more.Bulding up the VPN connection works, but it seems that the traffic is not tunneled. (I checked this, because tracert to an internal adress goes to the internet)Below there is my config, i don't know whats wrong. I think split-tunnel is configured correctly (because it works when i delete eth0/2.2) TREV is the network of this location.Company1,2,3 are remote locations.

I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network. There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well. Internet setup was cake. The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks. I have one MPLS with AT&T and one MPLS with EarthLink. My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS. I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.
Here's the topology I'm working with

This would be the first time I will be working on NCS for a client. There is completely a new install and I was just doing my reading to get my head around the overall working of the product. I had a small Q in mind which I wanted to ask here, while going the config guide, i could not find the way to add a router to the NCS prime. W have ASR 1001 in use along with switches. I read in some forum that NCS supported routers but couldnt find the way in the config guide unless i am missing somewhere. The NCS version is 1.0

I have a remove access vpn configured on my ASA 5510 which works fine, VPN pool easily allocates IP to all remote used , but they have few network drivers shared on their machines & most of them are linked using the computer name rather than the IP which normally doesnt work as VPN pool doesnt provides the DNS IP to the remote clients . Is it possible to allocate DNS IP with the VPN IP ?

I've some strange problems with multiple ASA (NEM) VPN remote clients (v8.4.5). On the HQ I've an ASA5510 (v8.4.5) with multiple NEM's connected to it. The group policy used on the HQ is configured for split tunneling. Now here's the problem;
The remote ASA (NEM) constructs easily a VPN connection to the main location; it seems that everything works well. Traffic through most of the tunneled networks works perfectly. Traffic to certain subnets or hosts brings me into trouble, there is no traffic flowing through the tunnel at all!
When using the command "show crypto ipsec sa | i caps|ident|spi” I can see all of the tunneled subnets. The subnets that works perfecly gives me the correct "local and remote ident" output. The subnets with problems gives me wrong values in the "remote ident". The remote ident should be the IP address of the inside LAN (of the remote NEM) and not the IP address of the ouside interface (of the remote NEM). How is this posible?
Here's is the crypto ipsec sa output:
Result of the command: "show crypto ipsec sa | i caps|ident|spi"
local ident (addr/mask/prot/port): (10.200.60.0/255.255.255.0/0/0) <-- this is the good subnet of the inside interface (NEM)
remote ident (addr/mask/prot/port): (10.100.2.2/255.255.255.255/0/0) <-- this is the good subnet (HQ)
#pkts encaps: 54712, #pkts encrypt: 54712, #pkts digest: 54712
#pkts decaps: 31893, #pkts decrypt: 31893, #pkts verify: 31893
#PMTUs sent: 0, #PMTUs rcvd: 0, #decapsulated frgs needing reassembly: 0
