Apr 17, 2013I have a PIX-515E version 8.0(2).I have two remote sites connected to this PIX via IPSec tunnels.Each remote site can reach the local networks behind the PIX but I can not reach remoteSiteA from remoteSiteB.So,
10.30.8.254 SiteA <----- IPSec -----> PIX1 <----------------> SiteX 10.0.8.1

SiteA can ping SiteX
SiteB can ping SiteX
SiteA can't ping SiteB
SiteB can't ping SiteA
If i do show crypto isakmp ipsec sa I can see appropriate subnets:

The decapsulated inner packet doesn't match the negotiated policy in the SA. The packet specifies its destination as 10.138.34.21, its source as 10.30.8.254, and its protocol as 6. The SA specifies its local proxy as 10.0.8.0/255.255.255.0/0/0 and its remote_proxy as 10.30.8.254/255.255.255.255/0/0
My question is really do I need to do anything funky to allow the traffic to pass between the two tunnels?
Cisco VPN :: PIX-501 IPSec To Configure Tunnel
Mar 24, 2011I'm attempting to configure a tunnel on a PIX-501 version 6.3. It's an old device that's due to be replaced soon, but unfortunately we need a tunnel now... I have been using this document as a reference (6211): URL ,The remote end is a sonicwall.
The problem seems to be that the pix never sees the interesting traffic for the tunnel, and never tries to initiate a connection. I have enabled crypto ipsec and crypto isakmp debugs, but no data is ever displayed, even when attempting to access a device on the remote side of the tunnel! Someone had tried to set up this device with some tunnels in the past, but was never successful, so I'm thinking there might be remaining commands in the running-config causing problems.

Apr 11, 2013I'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?

Apr 18, 2013We 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.

Cisco Firewall :: Management Port Routing On ASA5525x?
Jan 17, 2013I've got a client with a Management Port set up for Out-of-Band management. Here's the configuration of the interface and some relevant static routes:
interface Management0/0
description MGT
speed 100
duplex full
nameif Mgt
[code]...
The route through Mgt interface is required as my client accesses the device from a subnet that isn't local to M0/0.Unfortunately, now any traffic originating from outside and destined to 10.48.0.0/16 is choosing the Mgt interface. I had thought that the 'management-only' keyword prevents this from happening (traffic traversing between interfaces).
There is a broad scope of /16 addresses on the 'inside' so just swapping destinations won't work (the client wants to avoid a routing table with 50+ static entries, understandably)My temporary solution was to do this:
route inside 10.0.0.0 255.128.0.0 10.38.103.1
route inside 10.128.0.0 255.128.0.0 10.38.103.1
route Mgt 10.0.0.0 255.0.0.0 10.38.100.254
If 'management-only' doesn't prevent traffic from using the Mgt interface, what is the point of the command?
Cisco Firewall :: ASA 5540 - IPSec Tunnel / ASA Refuses To Encrypt Traffic But Decrypts It
May 31, 2012This 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 :: How To Configure 6 To 4 Manual Tunnel On ASA5585
Jul 6, 2012I have ASA5585 Firewall between my WAN Cloud and LAN Network. I plan to configure Layer 3 Vlan Interfaces inside FW and it would be Layer 3 gateway for some of Subnets. Layer 3 VLAN Interfaces are planned to be dual stack containing both IPv4 and IPv6 Address stack.
I plan to configure 6 to 4 Tunnel with my Hub Site where we have native Ipv6 awareness. One tunnel end point would be ASA and the other endpoint would be Hub site WAN Router/L3 Switch. So IPv6 traffic hitting to vlan interfaces on ASA would be policy checked and routed over tunnel interface to Hub Site.
6to4 Tunnel manual tunnel configuration on ASA. I have configured such tunnel on L3 Switch or Router with following config.
Int tunnel xyz
ipv6 address <ipv6 address>
ipv6 enable
tunnel source <loopback address of my L3 Switch>
tunnel destination <loopback address of my hus site L3 Switch/Router>
tunnel mode ipv6ip
end
I need to implement something similar in ASA. How can I do that?

Cisco WAN :: 2431 - Configure IAD So That Phones Are Routed Based On Destination Network
Jul 12, 2012Our ISP has set up a Cisco 2431-16fxs IAD (dual WAN) in one of our locations. It is used to connect the devices (PCs and SIP phones) on our LAN to internet (via 1st WAN port) and ISP's MPLS-based voip network (via 2nd WAN port).
We have 2 LAN subnets - the first subnet (PCs) requires internet access only, so it goes out via the 1st WAN port. The 2nd subnet (SIP phones) is connected the MPLS network (via 2nd WAN port).
We would like to have the SIP phones (that connects to MPLS-based network 192.168.1.x) to be able to access the internet. Is it possible to configure the IAD so that the phones are routed based on destination network; i.e. anything to 192.168.1.x via 2nd WAN port, anything else to the internet via the 1st WAN port?

Cisco VPN :: ASA Or 871 IPSec L2L To SSG-140 - Tunnel Is Up But No Traffic
Aug 8, 2012i am curently troubleshooting a ipsec l2l VPN between
1. ASA 7.2(4) to SSG-140
2. Cisco 871W to SSG-140
In both scenario's the tunnel is nicely established, and traffic goes into the tunnel, but nothing comes out. All encap's, but no decap's
It seems like a routing issue, but we can not find anything on both sites.
So maybe i m running into a (known) issue between cisco VPN equipment and the SSG-140?
Could it be a proxy-id issue? Cause they configure stuff like 10.1.1.0/24 and i configure 10.1.1.0 0.0.0.255
Cisco VPN :: 887 - Static NAT With IPSec Tunnel
Oct 29, 2012configuring some static NAT entries on a remote site 887 router which also has a IPSec tunnel configured back to our main office.
I have been asked to configure some mobile phone "boost" boxes, which will take a mobile phone and send the traffic over the Internet - this is required because of the poor signal at the branch. These boxes connect via Ethernet to the local network and need a direct connection to the Internet and also certain UDP and TCP ports opening up.
There is only one local subnet on site and the ACL for the crypto map dictates that all traffic from this network to our head office go over the tunnel. What I wanted to do was create another vlan, give this a different subnet. Assign these mobile boost boxes DHCP reservations (there is no interface to them so they cannot be configured) and then allow them to break out to the Internet locally rather than send the traffic back to our head office and have to open up ports on our main ASA firewall.
[URL]
So I went ahead and created a separate vlan and DHCP reservation and then also followed the guidelines outlined above about using a route-map to stop the traffic being sent down the tunnel and then configured static NAT statements for each of the four ports these boost boxes need to work. I configure the ip nat inside/outside on the relevant ports (vlan 3 for inside, dialer 1 for outside) The configuration can be seen below for the NAT part;
