I have a 5510 and a 5505 that I'm attempting to configure a simple VPN tunnel over. I have tried step by step configurations form CISCO ASA configs, as well as every source I can find. I have walked throught the config with IOS commands as well as Wizards. All my packets are dropped at the the inside or outside interface.
When I show SH ISAKMP command all I get are 0's straight down.
I'm attempting to debug an ipsec tunnel on an ASA 5510 (8.4(3)) and when I turn on `debug crypto ipsec` and then execute `logging monitor` I get an constant stream of TCP debugging events, is it possible to only view ipsec messages?

View 1 Replies View RelatedI am experiencing slow throughput on a L2L IPsec tunnel that we have between one of our offices on the west coast (WC) US and another on the east coast (EC) US. The tunnel endpoint on the WC resides on a 5510 and a 5545x on the EC. The DIA circuit speed on the WC is 45 Mbps and 200 Mbps on the EC. The throughput of this IPsec tunnel is maxing out at approx. 4 – 5 Mbps. The utilization of the DIA circuits at both offices is under 5% when running various FTP test transfers. Both devices have low memory and CPU utilization.
We have a 2nd office on the EC (45 Mbps DIA) which I built a tunnel on a 5510 with the WC office and it is experiencing the same slow throughput. In covering all my bases we have a colocation facility on the WC and in building a tunnel between the 2 WC offices I WAS seeing close to full line rate speeds over the tunnel. Additionally, I built a tunnel between the 2 EC offices and I saw full line rate speeds. With the physical distance between the WC & EC offices I would expect some loss in throughput speeds but I would not expect it to drop as low as 4 – 5 Mbps. In thinking something may be up with the 5510 in our WC office we shipped a 5505 to the WC office and we built the same IPsec tunnels on it and it is experiencing the same.
In working with our support vendor to try and solve the WC <-> EC throughput issue they had me change the MTU, TCP mss, DF-bit, types of encryption/hash on the IPsec tunnel but nothing has resolved it. We are not showing fragmentation or PMTU issues on the tunnel. In contacting the ISP of our WC office they mentioned that they do not have any type or rate limiting in place. Our WC ISP had a CCIE review our configurations but nothing was found.
i have a Ipsec tunnel between a ASA 5510 (Uk) & a router (France) that seems to be going down a specific times during the day. I have attached the sys log as well.
I cannot seem to copy & paste the config onto here for some reason so i have attched the configs, Ipsec details & syslog details from the asa.
I'm having an issue bringing a L2L tunnels up between my ASA 5510 and an ISPs Netscreens. I can establish the tunnels from my side by initiating traffic to the far end. The tunnels come up and stay up as long as there is traffic. Once the tunnels drop, they will not re-establish with inbound traffic. The only way to re-establish the tunnel is to send traffic outbound from our network. My ASAs are on ASA Version 7.0(8) in active/standby. [code]
View 2 Replies View RelatedJust bought myself an ASA5505 to replace a PIX 501, and having transferred over most of the previous config I've managed to get the two IPSEC VPN tunnels working as before.
Unfortunately when I try and SSH to the ASA the connection just resets instantly even when the tunnel is up. It seems as if the ASA is actively refusing the connection, though the log doesn't state this. I had always presumed that traffic over an established IPSEC tunnel was implicitly trusted and not subject to usual access-list rules.
I am unable to SSH to the ASA from the 10.0.0.x range, but I can SSH to a machine on 10.27.0.4 (so I know the tunnel is up and working)
Config (minus irrelevant sensitive information) is attached for reference.
Also - though I'm not sure how relevant it is given the tunnels appear to work - when I enter the line "crypto map meepnet-map interface outside" in config mode the ASA reports "WARNING: The crypto map entry is incomplete!" even though I have supplied the access-list, peer and transform-set variables.
Something a little odd happened the other night. I had spent the afternoon updating all necessary programs where updates were available, did a GRC shieldsup test, did a clean and test of my system with AVG and MBAM. Everything looked fine.I went online that night however and as soon as I went to my online banking website, I noticed that there was an outgoing attempt logged in my firewall (ZoneAlarm). It was blocked. The IP address is 72.167.239.239:80 - which apparently fits in GoDaddy's IP range. Googled it and saw that someone else had the same issue.

When the tunnel is coming up, those two lines appears in the captured traffic on the internal interface :
<private internal IP>.500 > <destination IP>.500: udp 541
<public external IP>.500 > <destination IP>.500: udp 541
When it's not coming up, the port nuimber for the public IP is not 500

I currently have an ASA 5510 setup with Dual homed ISP's and a remote access IPsec VPN setup to terminate at either interface. The first interface is named Outside and the second is simply called Outside-2. When outside the company(such as at home), the VPN client will connect on the Outside-2 interface and work normally. The problem is while testing on our DMZ, the VPN Client will not connect on the Outside-2 interface. It will try that interface fail to connect and then connect to the backup Outside interface. This isn't a huge concern because it still connects, but if we were ever to get rid of one of those connections, it would be nice to reliably test from our DMZ.
View 1 Replies View RelatedI have created an IPSec VPN between our ASA (5510) and a Cisco Router running IOS.Only problem i have is that the VPN goes down if there's no interesting traffic from the router and i can't find anything to initiate the VPN Tunnel from the ASA (so we need to wait 'till someone connects on the other side).
Is there any way to make this connection persistent, just like an ASA-to-ASA tunnel?
I'm in process of purchasing a new Cisco routers for our branches that will be used primary to enable IPSec virtual tunnel interfce with "tunnel mode ipsec ipv4". does the default IOS IP Base supports this feature? or i need to purchase DATA license or SECURITY license?

We have a Cisco 2820 that serves as a hub and our spokes are Cisco 871s. Its been working for a while and for some reason last week. Http and https traffic over the tunnel is having connection issues. I can Remote desktop or PCanywhere into the remote PCs. From that PC I can ping internal IP address or IP of the webmail server or internal webserver with no issue. But if I access it over the browser it times out or it will work and stop working again. Basically ica, icmp, pcanythere, rdp traffic works over the tunnel but not http or https.

i 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
I'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.
configuring 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;

I have been struggling for a few days with getting site-to-site traffic working across a L2L IPSec tunnel. At this point, I have the tunnel up, and I see packets being decrypted on the correct IPSec SA's when I ping from a local network computer on the ASA side to a local network computer on the router side. I cannot ping from one side to the other, but those packets are getting through. We have another L2L tunnel that is from that ASA to another remote site's ASA, and that is functional. I have mirrored the configuration for ACLs, etc. from that site, so I believe that the issue is with the packets getting incorrectly translated by the NAT/NONAT statements/ACLs on the router side.

In the main office I'm working with a ASA5510 CLI 8.4 and a static public IP address. The branches are using different Cisco 8xx routers and dynamic public IP address. The following picture shows the current configuration:As I mentioned an IPSec Tunnel between the main office "Intern"-LAN 192.168.1.0/24 and an outside LAN 10.10.0.0/24 is successfully established. Now there is a new intern "Admin"-LAN 192.168.2.0/24 at the main office. The users from the outside LAN 10.10.0.0/24 need the possibility to reach this new intern "Admin"-LAN.Can I simply route the traffic from 10.10.0.0/24 to 192.168.2.0/24 via the existing IPSec-Tunnel? Or need I a new IPSec tunnel between the outside 10.10.0.0/24 LAN and the new "Admin"-LAN 192.168.2.0/24?

I have a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.
