View 1 Replies View RelatedWe 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.
What are the possibilities that exist for running a site to site vpn in our environment with the following infrastructure Cisco ASA 5520 - running on a multiple context mode
-Cisco 3750 switches
-Microsoft TMG
I believe these options are limited in terms of providing end point for VPN.Is there a VPN module that we can buy for 5520 to run IPSEC VPN?

find attached Network Diagram for the same. All Firewalls used are Cisco ASA 5520.
Both VPN tunnels between Point A and Point B, Point B and Point C too are up. I have enabled Same security level intra interface permit command also.
How do i enable traffic originating from LAN Subnets behind Point A to reach LAN Subnets behind Point C without having to create a Seperate tunnel between Point A and Point C
We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.

View 1 Replies View RelatedI am building a site to site VPN from our headquarters to a customer. I am using an ASA 5520. The customer is using Cisco 3945 routers. The customer has two VPN termination points. The customer requests that we make one of their termination points the primary VPN connection and make the other termination point the backup in the event that the primary VPN fails. How do I configure this on the ASA? Does the below configuration fulfill this goal?
View 3 Replies View RelatedWe have 3 sites, with a Cisco ASA 5520 at each location.
HQ (Headquarters) internal network: 172.16.110.0/24,
DR (Disaster Recovery) internal network: 172.16.120.0/24
BO (Branch Office) internal network: 172.16.150.0/24
HQ and DR have a 100Mbps permanent MPLS link between each other.Branch Office has a Site 2 Site VPN connection to HQ. If it fails, it establishes a Site 2 Site VPN connection to DR. This works perfectly.Now the routing issue... There is no route to the BO in the routing table at HQ/DR. The default gateway is used to reach the BO and that works for HQ when the VPN is between HQ/BO. If the VPN fails over to DR/BO, HQ can't reach BO anymore.I need to have some kind of conditional route injection from the ASA where the VPN is established. I was considering a tracked static route, but I was wondering if the S2S VPN itself has a functionality to do so. I thought the Reverse Route Injection was it but it's enabled on our crypto map and doesn't seem to work...
I am noticing the following issue with one of our VPN connections:
Site A is connected to the Internet with an ISA Firewall
Site B is connected to the Internet with a CISCO 5505
Both sites are connected together via a VPN ,Both sites have around a 6MB up and 6MB down connection to the Internet
If I sent a 100MB file from Site A to B it takes around 30-45 minutes to copy, which to me seems excessive.
I've run Wireshark on the server sending the file (from Site A) and the desktop receiving the file (Site B). Initially, the server sending the file was generating a large number of TCP DUP ACK, TCP FAST RETRANSMISSION, TCP PREVIOUS SEGMENT LOST AND TCP OUT-OF-ORDER messages. I narrowed it down to IPv4 Checksum Offload and IPv4 Large Send offload which I disabled on the server. This sped up the file copy and massively reduced the errors in Wireshark, but not to what I think it should be. I then performed Wireshark logging on the desktop receiving the file which was also generating a large amount of TCP DUP ACK, TCP FAST RETRANSMISSION, TCP PREVIOUS SEGMENT LOST AND TCP OUT-OF-ORDER messages. I disabled IPv4 Checksum Offload and IPv4 Large Send offload options on the network card of the desktop and tried resending the file, which made no difference in speed and still generated the above messages in Wireshark.
I have run an mturoute between site A and B and get the following:
C: emp>mturoute.exe 10.0.66.2 (to PC on site B)
* ICMP Fragmentation is not permitted. *
* Speed optimization is enabled. *
* Maximum payload is 10000 bytes. *

I am using the Site to Site Wizard on an ASA 5520 and ASA 5505 from the ADSM. Both are using 8.4(5). When you create the configurations. Do you have to follow up the wizard configurations with manual ACL's to allow for traffic from each connected subnet to talk to each other? Or are they automatically generated in the configuration file? Have not been to school yet to properly understand how to create the VPN tunnels from the CLI and what to look for.

View 36 Replies View RelatedI try configure VPN site to site, with ASA 5520 and Ruter 891.The topology is LAN-->ASA 5520-->INTERNET<--ROUTER 891<--LAN.
The configuration of the VPN site to site on ASA5502 is UP, but in Router 891, I dont understand the commands. url...
I have a pair of ASA 5520s configured in failover mode that also acts as VPN endpoint for about 25+ site to site ipsec VPNs. Of the 25 sites, 2 sites consistantly are having VPN issues while the other sites never have this issue.
For example, at a branch office the network is 192.168.1.0/24, and at the headquarter the ASA has an interface with network 192.168.254.0/24. VPNs are setup to tunnel all traffic destined to the headquarter network 192.168.254.0/24 and a couple of other networks with public IP addresses not directly connected to the ASA.
When the issue occurs, I can ping anything in the 192.168.1.0/24 or the 192.168.254.0/24 range across the VPN, but I cannot ping anything in the public IP range. ASDM reports that the tunnel is up. Restarting the routers at the branch offices do not work.
So far, I have been able to resolve the issue whenever it occurs by doing the following, however this issue happening more and more frequently:
first, try killing the VPN tunnel and wait for the router and ASA to re-establish the tunnel, sometime that works. If that doesn't work, I would failover to the standby ASA. Sometime even that doesn't work, then I have to reload the standby ASA before I failover to it.
All these site to site VPNs are setup the same way for the same purpose (to tunnel ad/exchange traffic), and this issue only happens to 2 of the branch offices which are using different ISPs - I even switched one of the 2 offices to a different ISP and router recently - still have the same issue.
I have asa 5520 k8 model presently i am running with IOS version 8.0(4) i am upgrading to 8.2(5) is ? any license required from Cisco to upgrade to this IOS, and also let me know how many site to site vpn can be configure on this device.

Can the ASA 5520's support dynamic IP for site to site VPN
View 1 Replies View RelatedWe have a site to site client that is having issue with intermittent disconnects. The Main endpoint is a CIsco ASA 5520 8.4.3 and the remote site has a a Cisco ASA 5505 8.2.5.
If we have a disconnect, we can "logout" of the Main ASA and the connection seems to find itself and traffic will flow. This take place about every 1 - 5 minutes but if you reset the crypto (which I am assuming you do) by logging out under the Logging Monitor Session - ikev1 sessions. It all starts right back up.
I am stumped. At first I thought MTUs but I am not sure that is the answer.
We have one office and one construction site. The construction site connects to the office through site to site VPN but the applications used on the construction site goes very slow!
There is a Cisco asa 5505 at the construction site and a Pix Version 6.3(5) at the office. The ISP line is 100Mbit fiber at both locations. Speed check shows 80 m bit/s at the construction site and when my constructors pings the local servers the response time is about 10 ms. There is only small amounts of data that is going through the tunnel.Are there some limitations in the site to site software that is causing this? It is strange that it is so slow when speed check shows good result and ping shows good result.
I've got a problem,We are having site-to-site VPN tunnel connected with our Client. Usuall the users connect remote virtual desktop(may be Vmware) through the L2L tunnel. The problem is that the remote desktop gets disconnect intermittently(around 4 to 5 times a day) and automatically reconnects after around 40Seconds or so. I can't find any problem with the L2L tunnel as it is showing up for the last 6 hours or so.Also there is no packet drops(RTO) when I ping the peer IP.
