Cisco :: How To Connect ASA5520 With ISP Mpls Network
May 6, 2012
In HQ , we have cisco ASA 5520 . there is a data line which supplied by ISP for MPLS-VPN service with branch office. branch offices also have a data line which r supplied by ISP. And now, I want the branch office to access resource from HQ without site to site vpn configuration( because we don't have ASA or any device to configure L2L VPN) . so, I need to configure the hq firewall to allow the branch office accessing the resource at hq without any restriction.

I currently have a 150 nodes MPLS network. My management is anxious to join some sites with 3G routers as their centres move around a lot.My current MPLS site as 4 x Ps with lots of PEs linking to the 150 x CEs. Is there a way to easily link up my 3G routers to my MPLS network? I have heard DMVPN may be a solution, but not sure how to implement.

I have been having a heck of a time trying to configure my 5505 to allow the second segment on my network to use the internet. Office 1 has a fiber internet connection, and all traffic flows fine. Office 2 had gotten it's internet from AT&T, via a network based firewall injecting a default route into the mpls cloud. both offices connunicate to each other through the mpls.
When we added the fiber to office 1, we had the mpls people change the default internet route to the inside address of the 5505 and things worked fine. when AT&T attempted to remove the NBF defaut route, and inject the 5505's address as default, things didn't go so well.
AT&T claims that it is within my nat cmmands on the 5505, but won't tell me anything else. I assume that they are correct, and I assume that I am not good enough with the 5505 ASDM to tell it what to do.
Office 1 uses 10.10.30.xx addresses and Office 2 uses 10.10.10.xx - the 5505 inside interface is 10.10.30.2 the internal interfaces of the mpls are 10.10.30.1 and 10.10.10.1

I am trying to use Nmap to determine whether a certain IP address is available or not. However, the output of the scan shows that it scanned the subnet my computer is on and only one address in the network I typed in (MPLS network). Is there any way I can have Nmap only scan that one subnet and not all the others?

I am implementing QoS on our MPLS network. Our environment exists of a mix of Cisco 2960 and 3560 switches. The IPT system is Avaya CM with Avaya phones.The WAN network is a MPLS network.Ports are configured for access and voice vlan (no trunking), one vlan for voice, one for data (vlan 1 is disabled).I dont have Qos coonfigured on LAN just wanted to configure on WAN Router where my Mpls link is connected.I have 45 Mb Mpls links on all sites connected to each other.
I have multiple sites connected via MPLS and i have control at both sides.Current config is mentioned below in which DSCP marking is not done for signaling. What is the best config with example.Current Config on all Cisco Router where MPLS link is terminated at all sites. [code]

Our firewall expert has gone off on long term illness leave and I am trying to pick up the pieces :-(
We have an ASA 5520 (local office) talking to another ASA (remote office) via a VPN Tunnel.
My 1st problem is that I cannot ping from my inside network (local) to the outside interface of my remote ASA.
My 2nd is that I have debug enabled on my rules but am not logging anything.

I have a question about my ASA 5520, it worked well till two weeks ago, and suddenly cannot be accessed by SSH/Telnet/TFTP....only can use the Consoel port to access it now, but other VPN/ACL setting working well. [code] If I enabled the outside access for SSH like below, it works well for outside port.ssh 0.0.0.0 0.0.0.0 outside.

So I have a client with an ASA 5520 running version 9.0 (was on 8.4) that I am trying to get either IPSec or SSL VPN configured on. I got everything setup and tried to connect. However, I couldn't connect to either. I fired up the real time monitoring and didn't see any syslog messages referring to a VPN build up. I also enabled SSH/Telnet on the outside interface and cannot connect to the ASA outside interface. I can ping the outside interface and can ping the internet from the ASA. I did set up a test ACL on the ASA and ran packet tracer on it and the results came back fine.
There is an IPS in the ASA as well, but I disabled the ACL for that and still am having these issues. Part of me wonders if the ISP has something set up to block inbound traffic. This should be a business class connection.

We have an ASA5520 version 8.3(1) We have an existing VPN tunnel between us and our partner site. We need to add a new vlan to our existing VPN tunnel.
Where do we need to add the new vlan to in ASDM interface? Looking through using ASDM, I found 3 places.
Site-to-Site VPN:
1) Connection profiles
2) Advanced > crypto maps
3) ACL Manager

Equipment used:
VBrick Systems Inc., Model HPS 7102 HS-HD
Cisco ASA5520 Firewall
I have been trying to take a vBrick RTSP stream and stream it outside of our network:Inside our network, If I were to open VLC, and go to “Media”, “Open Network Stream” and paste rtsp://123.123.157.10/vbStream1S1 the stream works, audio and video. Outside our network nothing. I have opened ALL UDP and TCP ports to the vBrick 123.1123.157.10 on our firewall and tried from outside of our network:
access-list access-in extended permit tcp any host 123.123.157.10 range 1 65535
access-list access-in extended permit udp any host 123.123.157.10 range 1 65535
After adding this to the access list, the web gui http://123.123.157.10 (uses port 80) and ftp ftp://123.123.157.10 (uses port 21) is functional outside of our network...just not the rtsp stream which works fine internally.

in our VPN configuration (ASA5520, Anyconnect VPN Client), we have different VPN User Groups. These Group Policies are retrieved from an LDAP Server.We'd like to restrict the acess like this:
A Group "Home User" might establish a VPN from anywhere on the Internet
A Group "restricted 3rd party" should only be allowed to establish a VPN from their specific public Source IP Address on the Internet (the public IP Address of this 3rd party Company). When these Users try to connect from any other IP Address on the Internet(Home, hotel, etc), VPN Access should not work!
On our old solution, we were able to limit the remote access network, per user group, to some source IP's.
The IP Filters related to group policies in here seem only to be filters concerning the VPN Address (after the VPN is established: where can this user group connect to). But I did not find filters/access lists, where yoiu can define/restrict public access networks for some groups.Or is it possible to do that by Dynamic Access Policies? How?

I have a ASA 5520 which is intended to use as a VPN for clients using PDA, I think the PDA is a very old product that the VPN only support CHAP/ MS- CHAP, but seems it cannot connect the VPN, it will prompt "invalid username and password" (but in fact the username and password is valid when using PAP), below is the log i captured from the ASDM when the PDA is connecting the VPN. when i tried to connect it in windows PC, I also have the same issue if the VPN setting is using MS-CHAP, if I choose PAP, it can connect with no problem. But the PDA has no option of PAP. [code]

I have created an IPSEC VPN tunnel using a Cisco ASA5520 (corporate) to a Cisco SRP541W (remote). The corporate subnet is 10.1.0.0/16, and the remote subnet is 192.168.1.0/24. From the remote subnet, I can ping anything on the 10.1.0.0 corporate network, but I cannot ping from the corporate network to the remote subnet. At first I thought this was something obvious, perhaps an incorrect acl or something easy on the corporate firewall. However, we have several other vpn tunnels established, all set up the same, and they work just fine. After looking at it a bit more closely, if I ping the remote subnet I see the hit counter increment by one each time, which leads me to believe that traffic is in fact being routed properly.Now I'm thinking that something in the remote SRP541W that is not allowing icmp traffic, but I can't find it anywhere. To be honest I have never used this type of firewall before, they have all been Cisco PIX501/506e and ASA5500 models.

We received an ASA5520-K8 through Cisco's Loan program so we could demo it as a replacement for our aging Cisco 3005 VPN appliances. Given that we are a non Cisco shop (except for specific appliances like concentrators and wireless access points), I don't have a great deal of experience with Cisco gear.I started to set to setup the appliance this morning but immediately ran into issues. The 5520 doesnt seem to be acting as a DHCP server, and worse yet, I can't access the unit even if I hard code the IP on the PC being used for configuration. I have to say that I feel kinda stupid having to post this, since I actually followed the documentation avaiable for this menial task and I fully expect the problem to be a simple one. Namely, I am using two specific sources of info for connections.

this is ASA5520 associate with 8.4(1). very simple scenario , three ports: inside . outside . DMZ my problem is how to use network object NAT to perform Regular Dynamic PAT and Identity NAT.
for example, this is my configuration
**** first i configured Regular Dynamic PAT****
object network myinside
subnet 10.200.11.0 255.255.255.0
nat (inside,outside) dynamic interface
**** then , i met problem when i want to make identity NAT between inside and DMZ****
**** if i add below CLI , the first nat line will be replaced ****
**** SO IF I ADD THIS****

Just like to ask first your inputs about the MTUs needed on our proposed setup. We currently have a large internal network composed of several metro ethernet links. We have different carriers and we all know that they do not always provide L1 connectivity. They sometimes do Q-in-Q or EoMPLS or other technologies that would hide their internal network and appear as a point-to-point ME circuit to customers.
We are planning to create our own MPLS network for our clients so we don't have to leak their networks inside ours and we are trying to avoid the overhead of GRE/IPSEC since we'll be adding a lot of client networks and the overhead is not reasonable. So we just thought of MPLS-VPN to at least reduce the overhead and we don't have to purchase a lot of network devices.
With that said, what is the safest thing to ask the carriers and what settings should i put in our network devices. I am still confused with the differences of MTU, IP MTU, and MPLS MTU.
We also have one circuit running 802.1q instead of using routed-port on the switch. Is 802.1q supported in LDP?
Our internal network is comprised of 6500 switches with Sup720 and Gigabit linecards and we are planning to use 3900 routers as PEs. We all hooked up our ME circuits across the 6500 switches.

Recently i purchased Cisco 861-K9 router for my head office.
I have 2 offices (1 is head-office & other is Branch.). i have MPLS Connectivity between 2 offices.
i used 861-K9 WAN port for MPLS Connection.
My question is "is it possible to use the FastEthernet Port of 861-K9 router for connecting the internet Link ?"

I've got a 6509-E in the lab at the moment for some pre-deployment testing, however I don't seem to be able to enable MPLS on a select interface.
router#conf t
router(config)# interface gi1/48
router(config-if)#mpls ip
router(config)#
As you can see after I enter the "MPLS IP" command it simply backs out of interface level configuration back to global exec, and naturally the MPLS command doesn't show in configuration for that interface.
I'm running a SUP720-3BXL with WS-X6748-GE-TX line cards with the DFC upgrade (WS-F6700-3BXL).
The IOS is: s72033-adventerprisek9_wan-mz.122-33.SXI2a.bin

I have done a bunch of research in trying to re-use an old card/router for testing our new MPLS link. I have a 45m DS3 and was wondering if the PA-MC-T3= card will work UN-channelized. I have tried the "no channelized" command under the controller to no avail. I believe that the card only works for channelized T1's.
