I have created a site to site Ipsec vpn with a cisco 2610 and a linksys RV042. Running a show "crypto isakmp sa" command I get a qm_idle status and when running a "show crypto ipsec sa" I see that packets are being decrypted and encrypted. Also when running the "show ip access-lists" command I do have matches to that connection.The problem is that I am unable to ping hosts from one network to another. For example, from the Cisco router in network 192.168.0.0 I am unable to ping the remote network 192.168.2.0 and vice versa.
I am not sure what is happening. Do I need to create a route to that remote network? I guess it could also be a problem with NAT or an ACL.Here is what running-config shows:
crypto isakmp policy 1

I'm a CIsco ISR, Setting up my first ASA, which seems to be going well.I've setup an IPSEC VPN to a non Cisco device. And have connectivity between devices in each subnet.
-Subnet A - non Cisco - 10.10.13.0/24
-Subnet B - ASA 5505 - 192.168.2.0/24 (ASA is .254)
From Subnet A I can ping every device except the ASA on .254.
Edited Config attached, IP's changed for privacy, passwords removed.Let me know if I've removed too much of the config.
I have a IPSec tunnel that is working in one direction. Below is the router config from the side that can connect to the other side perfectly. I believe the issue is with this router as while I was waiting on delivery for the ASA I had an SRP527W sitting in it's place and had exactly the same problem.On one side I have a 887VA router and the other an ASA5505.The network behind the 887VA can access the remote site perfectly, backup services are traversing the link as are web interfaces for applications. In the other direction I can ping hosts but cannot connect. What else is interesting is if from the remote site I attempt to connect to a particular device that performs a port redirect the remote site browser gets so far as being redirected to port 5000 but then hangs.
I am seeing some very generic packet drop debug notices on the 887va on the NAT-ACL access list but I think this is as it should be as it is dropping the tunnel traffic from the NAT'ing.The config for the router is here, I will post the ASA config when I get to the other site shortly but I am convinced the issues is on this device, all the crypto configurations match.I have looked at the MTU's on each side, the path MTU on both sides is 1492. The asa does say the media MTU is 1500 but I believe that is the ADSL link so shouldnt matter?I even went so far as installing CCP and testing the VPN. It says the tunnel is up. It did state a failure:A ping with data size of this VPN interface MTU size and 'Do not Fragment' bit set to the other end VPN device is failing. This may happen if there is a lesser MTU network which drops the 'Do not fragment' packets. [code]
I have an existing site-2-site VPN between a Cisco 2621 router (IOS 12.3) and Cisco 1841 (IOS 12.3) and I can ping packet size of 17000 over the IPSec tunnel without any issue:c2621#ping 192.168.230.254 source f0/1 repeat 20 size 17000,Type escape sequence to abort.Sending 20, 17000-byte ICMP Echos to 192.168.230.254, timeout is 2 seconds:Packet sent with a source address of 192.168.208.254!!!!!!!!!!!!!!!!!!!!Success rate is 100 percent (20/20), round-trip min/avg/max = 144/146/148 msc2621#I replaced the Cisco 2621 with a more powerful ASR 1002 running IOS version asr1000rp1-adventerprisek9.03.01.00.S.150-1.S.bin. However, I can not ping packet size larger than 9200 over the IPSec tunnel:Feb 24 02:42:52.362: %IOSXE-3-PLATFORM: F0: cpp_cp: QFP:00 Thread:015 TS:00000015834854465792 %IPSEC-3-PKT_TOO_BIG: IPSec Packet size 10072 larger than maximum supported size 9216 hence dropping it.Success rate is 0 percent (0/10)asr1002# Why is not working? Basically the more expensive ASR router can not perform the same task as the old Cisco 2621 router.

I can ping the routers from each end no problem. I can ping the IPs listed in the "Local Group Setup" and the "Remote Group Setup" from both ends no problem. I can even open up a shared resource from a Win 7 machine (e.g. by typing \10.10.10.100 in start-run from a computer on my home network).
But - i can't ping anything else on one network from the other. What gives? I need to access a 10.10.10.101 machine but can't even ping it.
- both RVS4000 boxes have latest firmware (V1.3.3.5)

We have a number of sites running Cisco 881 routers. A few of the sites are connected by IPSec VPN tunnels that have been configured using Cisco CCP without any issues until now. On one location I can ping from a workstations on Site1 to Site2, however I cannot ping from the same workstation on Site2 back to Site1.
Here is a strange behavior. If I have a continuous ping going from Site1 - Site2 and then start a continuous ping from Site2 - Site1 then I get a response until I stop the ping from Site1 - Site2. Site 1 has approximately 5 successful tunnels with absolutely no issues.
Here is some site specific Info:

For additional troubleshooting I established a VPN tunnel from Site2 to our office Site3 with no issues at all. Site3 happens to be one of the VPN tunnels that connects to Site1 with no issues. I have seen a number of articles on this on the net and gone through the troubleshooting steps of an article such as [URL]. The tunnel is confirmed as up when I have done all my troubleshooting.
On my ASA5520 I am trying to do a IPSEC tunnel between two sites. When I ping the protected network on the other side I get this when debugging IPSEC:
IPSEC(crypto_map_check): crypt o map man map 20 does not hole match for ACL man1
Not too sure what this means...

Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.

I have a very basic lab site to site vpn setup where I have a ASA 5505 running v7.2(4) on one side and a cisco 2811 on the other side.
What's my issue?
I can't seem to ping from cisco router to the 'inside' network of ASA (see config below) and can't seem to ping from ASA packets leaving the 'inside' interface to cisco router even w/ an ICMP ACL permit outside in. However I'm able to ping within ASA inside network & ping cisco 2811 side w/ packets leaving ASA 'outside' interface just fine.
example:
-------
ciscoasa# ping inside 10.20.20.1 (to cisco loopback1 from ASA inside)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.20.20.1, timeout is 2 seconds:

I tried any type of combination and just couldn't make it works. Only PPTP works well. Whether Apple iOS IPSec VPN is supported or not?
View 11 Replies View RelatedI have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.
View 5 Replies View RelatedI set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

View 2 Replies View RelatedI had both a Westell 7500 and a Linksys Router working fine and had my 360 setup as an extender for Windows Media Center so I could stream TV, Music, Movies, etc from my desktop to the 360. Then I switched my modem/router out with a Zyxel PH5001Z
So now today I noticed that I can no longer find my desktop through the XBox. I have adjusted my firewall settings on the modem itself, even completely disabling it. UPnP is enabled for the 360 and the device is showing under my device table. At first I wasn't able to ping any network devices but after creating an ICMPv4 Firewall rule it worked fine. I've confirmed the XBox IP Address through Network Map, the Device Table on the modem and through Network Settings on the XBox. I've diabled my modem firewall as well as Windows Firewall, completely and I still can't ping my XBox or set it up as an Extender.
I have the XBox connected wirelessly using WPA2-Personal and it's operating in 802.11g/n mode.

View 3 Replies View RelatedI'm trying to establish vpn session between 2 Cisco 892/k9 routers. but when i apply the crypto map in the GRE tunnel interface this type of message apears.
NOTE: crypto map is configured on tunnel interface.
Currently only GDOI crypto map is supported on tunnel interface.
As the same crypto map is easily applied to the physical interface instead of GRE, and It works too... What causes the problem based on the Debug output and configurations which i have attached with this message.
I'm trying to setup an IPSEC tunnel above GRE using the topology in the attached image file.However the traffic between the 2 endpoints: lo0 on R5 (10.0.5.1) and lo0 on R4 is traveling via the GRE tunnel without being encapsulated in IPSEC: I'm using 2 routing protocols:
- OSPF area 0 for the connectivity between R1,R2 and R3
- EIGRP AS 1 for the internal sites connectivity
I want to establish GRE over IPsec tunnel between four branch offices and head office. At branch offices, I have 1841 router with Advanced Security software. At head office, I have a ASA5510 7.2 as frontend with one public IP addres and 1841 router behind it in private address space. Since ASA is not supporting GRE tunnels, can ASA be endpoint for GRE over IPsec? If not, can ASA pass this tunnel to the 1841 router behind it, so 1841 would be logical tunnel endpoint? What should I pay attention? Should both ASA and every 1841 support NAT-T, or just ASA?

i have 6 sites using tandberg visioconference system, each site have a cisco router 1841 configured with ipsec vpn, i have a 4 conference a week and my bandwidth is 2 meg, and when people are working we have a lot of problems and cut in our visio conference.
I have a big problem, i want to make a high level QOS priority to my TANDBERG visio conference system between my sites, the issues is that there is an IPSEC VPN in my cisco routers between those sites and as i know if the traffic is crypted we can not separate the packets or give higher priority to packets over anothers.
can i mark traffic in the lan interface and and make a high priority befors the packets go through the ipsec tunnel?
