Cisco Firewall :: ASA 5520 - IPSec Tunnel Without Private Network

Apr 11, 2013

I'm trying to achieve a site-to-site ipsec tunnel to a Cisco ASA 5520.  Most examples feature the ASA with a public interface that terminates the tuennel and a private network on another interface that the tunnel interacts with.  Where my scenario differs is that the interface that accepts the tunnel is part of a public /29 network where I want the remaining hosts on that subnet to be able to route thrugh to the other end of the tunnel.  My tunnel gets established, but any attempts to route via the IP assigned to that one interface result in the ASA rejecting traffic. If so, what configuration options should I consider?

Cisco VPN :: 3925 - LAN-LAN IPsec Tunnel Command Unavailable

Apr 14, 2011

I'm looking to utilize one of my 3925's to create a LAN-LAN IPsec VPN tunnel with another site.
 
I was under the impression that I needed to get a securityk9 license installed and then I would be good to go.   I got a temporary 60 day trial license and successfully installed it, but none of the commands that I need to create the tunnel are showing up for me.
 
I'm trying to use the "crypto isakmp" command, but that is not showing up: Router(config)#crypto ?   ca   Certification authority   key  Long term key operations   pki  Public Key components
 
Here's my show license:
Index 2 Feature: securityk9
Period left: 633 weeks 4  days
Period Used: 0  minute  0  second
License Type: Evaluation
License State: Active, Not in Use, EULA accepted
License Count: Non-Counted

Cisco WAN :: 871 / 5520 - L2L IPSec Tunnel Between Two Routers

Apr 4, 2011

Here is the situation: A CISCO871 router is configured to establish an IP SEC tunnel with a CISCO ASA5520. The configuration is OK about that. I wish to configure the same CISCO871 in order to establish a LAN-to-LAN IP sec Tunnel with another CISCO871 at the same time in order to reach private network. So, I have followed the Cisco procedure Document ID: 71462 "LAN-to-LAN IP sec Tunnel Between Two Routers Configuration Example"; it works, I can reach the peer private network BUT ONLY when the IP SEC tunnel with ASA is not established.
 
It seems to be a routing problem...I don't find how to configure to make both tunnels up and functional at the same time.

Cisco VPN :: Establish Site To Site IPSec Tunnel Between ASA 5520 And 3030?

Feb 17, 2013

We have configured a site to site tunnel from our ASA to another organizations Cisco 3030.  It appears to have just one way initiation.  We can do a ping to a device on the remote site and it will ping just fine.  however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
 
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional.  And once established, traffic can flow bidirectional.

Cisco Firewall :: PIX515 / 2821 / 2921 / Getting GRE IPsec Tunnel Setup?

Apr 18, 2013

We are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router.  I am attempting to setup a GRE tunnel over IPsec back to the main office.  The main office consists of a PIX515, a 2821 router, and a 2921 router.  
 
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices.  The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well.   The default route is to use the ASA.   We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515.  Right now I am not able to get the tunnel setup.  It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls.  I will show the output of that command below. 
 
Main Office The external address     198.40.227.50. The loopback address   10.254.10.6 The tunnel address        10.2.60.1
 Offsite Datacenter The external address     198.40.254.178 The loopback address   10.254.60.6 The tunnel address        10.2.60.2
 
The main office PIX515 Config :

Cisco Firewall :: ASA 5540 - IPSec Tunnel / ASA Refuses To Encrypt Traffic But Decrypts It

May 31, 2012

This has to be the most weirdest issue I have seen since the past year on my ASA. I have an ASA 5540 running the 8.4(2) code without any issues until I stumbled upon this problem last week and I have spent sleepless nights with no resolution! So, take a deep breath and here is a brief description of my setup and the problem:
 
A Simple IPSEC tunnel between my ASA 5540 8.4(2) and a Juniper SSG 140 screen OS 6.3.0r9.0(route based VPN)
 
The tunnel comes up without any issues but the ASA refuses to encrypt the traffic but decrypts it with GLORY! below are some debug outputs, show outputs and a packet tracer output which also has an explanation of my WEIRD NAT issue:  

My setup - ( I wont get into the tunnel encryption details as my tunnel negotiations are **** perfect and comes up right off the bat when the ASA is configured as answer only)
 
CISCO ASA - IPSec networking details
LOCAL NETWORK - 10.2.4.0/28
REMOTE NETWORK - 192.168.171.8/32
JUNIPER SSG 140 - IPSec networking details
PROXY ID: LOCAL NETWORK - 192.168.171.8/32
REMOTE NETWORK - 10.2.4.0/28 
HOST NAME# sh cry ipsec sa peer <JUNIPER SSG PEER>
peer address: <JUNIPER SSG PEER>
[code]... 

As you can see, there is no echo reply packet at all as the packet is not being encapsulated while it is being sent back. I have been going mad with this. Also, this is a live production multi tenant firewall with no issues at all apart from this ****** ip sec tunnel to a juniper!!

Also, the 192.168.10.0/24 is another IP Sec tunnel remote network to this 10.2.4.0/28 network and this IP SEC tunnel has a similar Juniper SSG 140 screen os 6.3.0r9.0 at the remote end and this woks like a charm without any issues, but the 171 is not being encrypted by the ASA at all.

Cisco Firewall :: ASA 5520 8.3 VPN Tunnel Drops Traffic

Aug 23, 2011

We have a 100 Mbps WAN circuit, we have configured an IPsec tunnel between ASA 5520 and Cisco 3845 Router for our DR site replication via Veeam Backup and Replication, it was working fine before, when we established the 3DES tunnel the traffic for certain subnets is dropped after an hour and it stops the replication, although tunnel remains up and we can access the other subnets, as soon as we clear the crypto SA and ISAKMP sessions on the firewall the traffic starts flowing again and then after an hour the traffic is dropped again.So far the testing and differnet configurations we tried are as under.
 
Tried with a different MTU size both on firewall and ESXi servers but nothing happened.Their is no QOS configuration.Checked the utilization on both ends its Noram although their are subsequent 100% spikes on Cisco 3845 but on average it remians at 30-40%.

Cisco Firewall :: 5520 - Remote Access VPN Through A Tunnel?

Oct 17, 2011

I have a site to site VPN between SiteA to SiteB which is working fine. SiteA has an ASA5520 and SiteB Pix501. The ASA5520 is running version 804 with split tunneling. Users connect to SiteA using remote access VPN. Is it possible to setup SiteA ASA5520 so that when users connect to SiteA they can access servers located on SiteB through the tunnel? I know i can setup the Pix501 for remote access VPN but it is located in another country and i don't want to take a chance just incase i lose connectivity.

Cisco Firewall :: 5520 - SSH Socks Tunnel Set Up On Server

Jul 18, 2012

I have the following setup 
|| Socks Server || >> Switch1 >> ||Cisco 5520 ASA || -->> | Switch 2| -->> Clients
 
I have a SSH SOCKS tunnel set up on the socks server which is a Linux box. When I connect my machine to the switch 2, I am NOT able to receive and mail by setting up a mail client and it seems SOCKS traffic does not reach the socks server. I can however run a telnet command on port 1080 (socks port) which connects  which shows that the port was going through and open. However there was no SOCKS traffic. When I connected the machine to Switch 1, SOCKS traffic worked as expected and I was able to receive mail.

This suggests to me that the ASA has some inherent rule that does not allow SOCKS traffic. IS this true and if so how can I bypass this?

So I created a network object with 10.10.249.128 / 25, and used dynamic PAT to translate the source ip address to the external internet facing outside interface:
