Cisco Firewall :: ASA 5510 - Vpn Tunnel Not Working From One End
May 9, 2013
I have an ASA 5510 and I am building a site-to-site vpn tunnel, peer on the other end is a sonicwall. I can initiate the tunnel from my end, but when he tries from his end it fails on phase 2 with this error in the logs:
"Rejecting IPSec tunnel: no matching crypto map entry for remote proxy"
Obviously our crypto map's don't match, i have it restricted to specific ports on my end and he had it wide open on his end, but said he is not sure how to restrict it down to specific ports. My question is why would I be able to bring the tunnel up on my end if the crypto map's don't match and he can't bring it up?

Firewall ASA5510. I'm planning to get one of ASA5510 for our office in order to secure our network properly, however we have quite specific routing configuration to allow us failover to the remote location (data center) in case of any disaster with our server. I'd like to find out if I can just install firewall between our ISP Ruter and internet and allow traffic to/from Data Centre. In this situation will I have to change routing configuration on Company Router or do I have to do anything with our Company Router

I don't know if this is in the right section, but I cannot set up a vpn tunnel between an asa 5510 and a cisco rv042 router. I believe the problem is because i need to set up a nat exempt rule on the rv042 route but don't know how.

I have our main site using a Cisco 5510 running 8.4.2 code and a remote site using a Cisco 5505 running 8.4.2 code. The main site has a T1 and the remote site is using a DSL connection. About every other day I have to reset the connection at the remote site. The process that I have found that works is to remove the nat statement, clear the cry ips sa and then add back the nat statement. The connection usually comes back up and a few minutes. I am trying to see what is causing this to drop.

I have a dynamic VPN site to site between a Firewall ASA 5510 with ASA version 8.2(1) (firewall ASA have a Static IP 201.111.14.114) and a C870 ISR (the ISR have a dynamic IP). The tunnel and the conectivity in both sides is successfull, however each time that occurs a interface restart because the Internet link is unstable in ISR side the VPN tunnel does not going to UP STATE again
These are the ISR logs listed when VPN going to DOWN
*Mar 10 13:58:45.157: %LINK-3-UPDOWN: Interface ATM0, changed state to down
*Mar 10 13:58:46.157: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM0, changed state to down

I am not a ASA expert but I have configured them few times. I have a vision of a task I have to complete but not sure if it is practical or how to go about doing it.
We two locations, Location A and Location B. Both locations have a 100MB internet conection. Location A has a ASA 5510. Location B has a 5505. Users at both locations access the internet via their respective ASA. Location A is the headquarters and Location B is a disaster recovery site. We want to setup a tunnel between both ASAs. This tunnel will be used to replicate data between the two locations for DR purposes. We need the users to still use the same pipe to get to the internet but want to allocate 10MB for internet use and the remaining 90MB for the DR tunnel.

So I've run into a problem on my ASA5510, post-upgrade I can no longer connect to the inside interface from across our L2L VPN. I've tried both ASDM and SSH and the connections fail. I see in the logs that the attempt is being made, but it will eventually time out. There have been no problems with this type of connection with any previous upgrades, just this particular upgrade, I went from 8.4(1) to 8.4(2). I don't see much in the release notes or anything in a pre/post config diff that jumps out as a cause to this behavior. The only thing I did see in the release notes "CSCtg50770 Mngt-access (ASDM,SSH) to inside intf of 5580 fails over RA VPN session" which sounds like it could be my problem, but that was in the "Fixed in 8.4(2)" section and says it's for a 5580, maybe the fix for the 5580 broke it on a 5510??? I hope not and that I'm simply missing some new setting that I need to enable for this type of connection as this device is in a remote office.

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 configured ASA 5510 with IOS 8.4.2 version. I configured SSH to outside and backup interface with any any permission.
ssh 0.0.0.0 0.0.0.0 outside
ssh 0.0.0.0 0.0.0.0 backup
configured password with command
passwd < Password>
While connecting from outside through Putty i am not able to authenticate the password.
Aftter entering user name as pix its asking password. After entering its not authenticating.
I taken output by telnetting to inside after connecting to the firewall from outside and entering username as pix

Our NOC is trying to configure a site to site tunnel to one of our customers. The tunnel is up and operational, however we can't get our NAT rules to match what we want.
We are running ASA version 8.4(3)
The traffic is sourced from 172.16.1.50 (inside1) and destined to192.168.2.9 (outside), the nat configuration is posted below:
NOC-ASA5510-01# show run nat
nat (inside1,inside2) source static ng-noc-networks ng-noc-networks destination static ng-inside2-networks ng-inside2-networks

object network obj_any
nat (inside1,outside) dynamic interface dns
object network servers-noc
nat (inside1,outside) static 192.168.1.68
Here is the output from the show nat detailed:

I've got an ASA 5510 running 8.4.I have a host on an inside interface, with a static NAT configured on the ASA. The inbound/return half of the NAT doesn't appear to be working. [code] I run a ping from the host (192.168.100.98) to something on the outside (1.2.3.4)Running captures, I can see the outbound ping leaving, having been NATed OK. I can see the reply coming back in to the outside interface with the correct IP address, but I never get the final NATed packet appear on the inside interface. The packet just disappears inside the ASA.

I find are steps to turn on SSH access. I have quite a few customers with ASA5510's installed. SSH is set up and working fine on every one. After a period of time, you are no longer able to SSH into the firewall. Using Putty, it just sits there on a blank screen without giving a "denied access" message or a login prompt. Rebooting the firewall will solve the issue and SSH access works again. Today, I had a customer with and active/standby configuration where I had to reboot both of them to be able to log in. Most of my customers are on 8.2.software as most don't want to reconfigure for the new NAT, etc.
I'm sure others have seen this before since it appears to be occuring on almost every ASA that I have access to. Is there any fix to eliminate this or is there something that can be run from the ASDM that will grant SSH access again without just doing a reboot?

we recently upgraded our ASA 5510 active/standby cluster from ASA Version 8.3.2 to 8.4.1(11). Unfortunately the standby ASA is now crashing a few seconds after the configuration was synchronized from the active ASA.
Also completely disabling HA, bringing the default config to standby ASA again and activating HA afterwards did not work. Also tried through the Wizard provided by ASDM to be sure to have no errors with requirements.
How to solve this without doing a downgrade back to 8.3.2. ?

I have an ASA with an outside ACL that is configured to allow 208.84.248.95 SIP/5060 to 1x.x.x.46. I show no hits. I added an ACL to do a packet capture, it sees the packet coming into the ASA but not going to the Serv Prov interface. I see hits on the vuong ACL but not the production acl_out ACL.. What is up?
NOTE:ACL_out is the ACL we use to allow outside traffic to enter our network.
FW1(config)# sh access-list | i 1.x.x.46
access-list acl_out line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0xc09a9387 (*NO HITS)
access-list acl_out line 658 extended permit udp host 208.84.248.95 host 1x.x.x.46 eq sip (hitcnt=0) 0x0f327179 (NO HITS)
[code]...
It was tested and verified from the inside network to make sure the server is listening on that port. Below we created an ACL to allow all IP from another test PC to the Server IP 1x.x.x.46. We did a telnet to port 5060 and it showed hits but not on the acl_out ACL.
ccess-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0x2759fa92
FW1(config)# q
FW1# capture capture1 access-list vuong interface outside
[code]...
Below we applied the same ACL to the ServProv interface to see if traffic was going where it was supposed to . By trying to telnet to the 1x.x.x46 IP from 63.x.x.140 IP. Looking below, no traffic appeared on the capture2.
FW1# capture capture2 access-list vuong interface ServProv
FW1# sh capture capture2
0 packet captured
0 packet shown
[code]...
Capture 1 above shows the last 3 incoming messages initiated from 63.x.x.140 to the 1x.x.x.46! Vuong ACL belows shows 3 more hits.....nothing on the acl_out ACL???
FW1# sh access-list vuong
access-list vuong; 1 elements; name hash: 0x29df3e90
access-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=6) 0x2759fa92

I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
4 Sep 20 2011 16:20:33 fw_outside_ip 62678 outside_host 2001 Deny tcp src outside:outside_host_ip/62678 dst inside_host:inside_host_ip/2001 by access-group "outside_access_in" [0x0, 0x0]
When I try to use the packet tracer to simulate the outside traffic, I get the following
5 Sep 20 2011 16:17:41 inside_host 2001 Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:outside_host/1065 dst inside_int:inside_host/2001 denied due to NAT reverse path failure
I've got over my NAT statement and access rule and can't find anything wrong with either.
Here are the pertinent NAT and access rule...
static (inside_int,outside) tcp interface 2001 inside_host 2001 netmask 255.255.255.255
access-list outside_access_in extended permit tcp host outside_host host inside_host eq 2001

I have ASA 5510 connected as shown in attached diagram.Ideally when ASA 1 is active and if I boot Switch-1, ASA-2 shood take over. But that is not happening.When I boot SW1 , ASA-2 shows "Failover LAN Interface: failover Ethernet0/0 (Failed - No Switchover)" and remains standby.Fail over works properly If ASA-1 boots.

I have an ASA 5510 and have just started using object-groups which are super handy in theory, but not working in reality. I have a service object-group with a mix of tcp, icmp, and udp ports. Let's call it Sample_Port_Group. I'm trying to apply it to my dmz_access_in ACL. Here's the line giving me problems:
access-list dmz_access_in extended permit object-group Sample_Port_Group 192.168.1.1 any
The asa throws up an error between 192.168.1.1 and any. When I put up a ? after Sample_Port_Group, it gives me the option of putting in an IP address, any, etc. When I put in a ? after 192.168.1.1, it only gives me the option of putting in an IP address.URL
Those posts gave me the impression my line was possible, especially the "access-list outsideacl extended permit object-group myaclog interface inside any" line, which is at the end of the 2nd article linked.

I have a ASA 5510 that has multiple site to site VPNs. I need to create an additiona site to site VPN but only allow 1 host to access and traverse the tunnel. The network is on a 192.168.5.x but the host that will need to access this tunnel needs to be on a 172.16.33.x network. I dont want any other traffic allowed to access or traverse the VPN tunnel for this host. How can I set this up?

I know that I've run into this before but I can't remember the fix. I have a 5510. The 3 interfaces involved are INSIDE, OUTSIDE, and GUEST. Corporate users are allowed to put their iPhones on the Guest network, but the problem is that their Exchange ActiveSync stops working. It is tied to the external DNS name of the OWA server (we'll say webmail.abc.com). So the users are funneled out one public IP on the OUTSIDE interface and are trying to communicate with the outside of the OWA server, which is NATed to another public IP on the same outside interface. What do I need to do on the ASA to allow users on the guest network (behind the GUEST interface) to access the mail server using its public IP (behind the INSIDE interface)

After I have upgraded our ASA 5510 to 8.4.2 I have problem with the management interface.Our former firmware 8.2.3 had no problem using the management interface as a DMZ zone, but after we upgraded to 8.4.2 we can't make it work.The interface and the protocol is up, when I type: show interface.But when I ping the interface from a computer connectet to the interface, nothing happens.
Even the logging shows nothing.

We currently run dual ASA 5510's in A/S config on our main campus. We would like to create a VPN tunnel to a branch campus. Trying to decide between a 5505/5510/5512x, We would like to extend many of the capabilities of our network to the branch campus which will be 20-50 users on a 50mb/10mb internet connection.
Domain login
System Center workstation management
Cisco WCS
Shoretel voip
(Cisco NAC?)
Several different VLANs for wireless guest, student traffic, staff traffic, voip traffic, etc. Which device would be best and should we get the security plus license with it?

I am using a Cisco ASA 5510. Our tunnels always drop due to inactivity, which is a security issue I understand, and it only takes some "interesting traffic" to bring it back up. My problem is that it looks like the interesting traffic has to originate from my side of the tunnel, when our clients send traffic and the tunnel is down due to inactivity it does not come back up. Is there a setting that I am overlooking that will make it come back up no matter who sends traffic? Or, is there a way to make it stay up through inactivity?

I have been struggling to come up with the proper config to do a NAT of an incoming VPN tunnel to a VLAN on my network. I have an ASA 5510 with an IPSEC site-to-site tunnel to a partner network of 166.110.0.0/17.I have several VLANs on the ASA interface behind a cat4500 router (192.168.100.024, 172.16.4.0/24, 166.110.128.0/22 etc). The only network that the partner network sees is the 166.110.128.0/22.My problem is that I need to give them access to a node on my 192.168.100.0/24 net, but can't get the admin on the other side to add a route and adjust his tunnel.
