Cisco VPN :: Establish IPSec Tunnel Between 2801 And Cyberoam Equipment At End Point?
Mar 31, 2011
i'm triyng to establish a vpn ipsec tunnel between my cisco2801 and a cyberoam equipment, at the end point.Debugging isakmp, i have this output, where xxx.xxx.xxx.xxx is the remote peer address, and yyy.yyy.yyy.yyy is mine.What can i try?

I´m getting a dynamic public IP from my provider and what I´m trying to do is to establish a remote vpn tunnnel using IPSec which I achieve but every time the sessions resets or the ASA 5505 resets I get a new public IP and I need to put the new IP on the remote client so I can establish the vpn... How can I establish an ipsec vpn using DNS? For this scenario the remote vpn client is a vpn phone but it could be for any vpn client.
Private IP Public IP Private IP PBX ---- (LAN) ---- ASA 5505 ---( Internet ) --- Remote Site ( Router ) --- (LAN) -- VPN Phone
I have a client that needs to establish a IPsec tunnel to a large organization. They will not forward any traffic to an IP using private reserved IPs. However I am not finding another way to accomplish this. I tried ipsec to the router and using a second IP to a 1:1 Nat but it will not pass the traffic and would seem really insecure from the public internet. 1:1 Nat does work from the public internet but not over the tunnel.I have an RV042 a /29 block of IPs. I am at a loss of how I can accomplish what they want without allowing a private IP.
We 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.
I want to establish VPN with GRE over IPsec. As ASA can't end GRE tunnels, I should pass it through inside to another 1841 router in datacentar network. Since datacentar is connected to internet via two wan links (separate ISPs) is it possible to establish two gre simultanous sessions between 1841 at branch office and 1841 at datacentar, one session per wan link at datacentar? That way, I need 8 gre separate sessions (tunnels) at datacentar 1841 router. Is it supported?Is GRE passthrough works like regular port forwarding or it is something that ASA handles with some special commands?
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?
I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.
I have a Cisco 2801 with flash: c2801-advipservicesk9-mz.124-16.bin where I use to doing VPN IPSEC.My problem is where I do a connection with a client, if my VPN dont have a traffic, the tunnel are closed. If a receive or send any traffic, the tunnel get up again.If don't have traffic, this tunnel is closed and after is opened other tunnel where is changed the conn-id to 999 for example.This comportament is normal? Exist a form that my tunnel never close? I enabled the parameters below: [code] But the tunnel continues closing if a don't have traffic.
We are setting up a new VPN from an ASA to a cisco 2801 router (behind a third parties checkpoint firewall). We seem to be almost there with the setup but the tunnel is not working correctly. I have included a debug from the 2801 router and its config and a diagram of the setup. [code]
I've been labbing on my asa5505 at home, setting up different VPN solutions for testing purposes. However, I can't get my anyconnect client to establish a DTLS tunnel when connecting (anyconnect only shows tls, and does not display any errors about not connecting with dtls)I have set dtls port to 444 and this port is open on the other side.
We have to configure our firewall cisco Asa 505 (ASA Version 8.3(1)) in order to establish a ipsec vpn between our office site and another external site. Vpn has been established successfully between our ip site 172.16.69.24 and other vpn ip site 172.16.23.23.Our server (192.168.100.25) behind firewall cisco (sk lan 192.168.100.254) manages to ping server 172.16.23.23 on other site through a static route add on windows so server (route add 172.16.23.0 MAK 255.255.255.0 192.168.100.254).On the other site, server with ip 172.16.23.23 doesn't ping our vpn ip site (172.16.69.24) which has to be natted to our server 192.168.100.25.
I'm trying to gather netflow data over an IPSEC VPN and through my research I've learned that I need to configure Flexible Netflow. However, I have a Cisco 2801 router with the latest ROMMON and IOS and the Flexible Netflow options aren't available.
I run 2801 with 124-24.T3 and I have following problem: router is connected to internet over pppoe and ISP once per day breaks this link. so I get:
Jun 7 19:31:56.639 MSK: %DIALER-6-UNBIND: Interface Vi2 unbound from profile Di1 Jun 7 19:31:56.663 MSK: %LINK-3-UPDOWN: Interface Virtual-Access2, changed state to down
and I also have tunnel interface which endpoint is accessible over internet. so I get:
Jun 7 19:31:56.679 MSK: %ADJ-5-PARENT: Midchain parent maintenance for IP midchain out of Tunnel1 68844500 - looped chain attempting to stack Jun 7 19:31:57.635 MSK: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to down Jun 7 19:31:59.199 MSK: %TUN-5-RECURDOWN: Tunnel1 temporarily disabled due to recursive routing
this is not a problem, problem is that router when interface goes down removes service-policy output from it, so I receive such message every day from runcid:
ip ospf cost 1 ip ospf mtu-ignore tunnel source Loopback1 tunnel destination 192.168.200.199 - service-policy output tunnel_mpr_gre and have to restore policy manually.
I have an issue where I can get traffic to pass from HDQ to two branch offices over our ipsec/gre tunnels even though the tunnels appear to be UP. The HDQ is a 2811, branch is a home office using an 871W and branch runs a 2801 router. I initially had HDQ working fine with the 871W but when I configured branch2 (2801), they both broke. The tunnels appear to be up but traffic is not routing across them. The two 2801 routers run 12.4 (c2800nm-adventerprisek9-mz.124-24.T2.bin). These are gre over ipsec tunnels. Currently traffic flows over an exsting MPLS network that we are getting away from due to cost. As soon as I change the routes to point to the Tunnels, it breaks. Traffic doesn't appear to pass through the tunnel. I have attached my sanitized configs.

So I've decided to use a different router to resolve some VPN issues, and want to use my DIR-655 as a pure wireless access point. I need the access point to use the same range of IP addresses as the rest of the network (maintain access to networked printers, file shares, etc). However, I can't establish a wireless connection to the access point.
- Defined a IP address for the DIR-655 within the DHCP range of the primary router - Defined the proper subnet - Disabled the DHCP server on the DIR-655 - Connect a LAN port of the DIR-655 to a LAN port on a switch (note that it's not connected directly to a router).
When I connect a device WIRED to a LAN port on the DIR-655, everything works fine. The device gets assigned a DHCP address (which I know is being assigned by the main router since the DIR-655 DHCP server is disabled), and I can connect to the LAN and I can access the internet with no problem. So I know the DIR-655 is acting correctly to pass thru traffic. Also, I can access the DIR-655 web configuration page from any LAN device (even a device not directly connected to the DIR-655), so I know the DIR-655 is on that LAN correctly.
But when I try to connect WIRELESS to the DIR-655, it doesn't work at all. Although the wireless NIC is connecting to the DIR-655 (e.g. it asks me for the WPA key), it can't pull an IP address, so there is no connection to the LAN or internet.
I got an Fritz Box from my new Provider to connect to the internet using Fiber To Home. the box is now im my living room and also acts as an WLAN Router. I would like to configure my WRT54GL which in located in my office from a router to a repeater to establish a WLAN bridgde.
Can I configure a PIX (515), as PPTP client to establish a tunnel with non-Cisco PPTP server ? Can my PIX initiate this type of connection ?Today, I use a PC with PPTP client to establish this and I want replace this with a PIX and I don´t want depends of a PC.
As you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:
Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.
I am trying to establish a connection with an already existing IPsec VPN for file sharing. I click on the icon and get error messages when I type the correct username and password. I also entered the shared secret key correctly. I do not know where to enter the "group" name that coincides with the key I was given.
- Ipsec tunnell between two 881's - An Aruba access point trying to set up a tunnell back to controller through the ipsec tunnell, on udp 4500 - Even though traffic shouldn't be NAT'ed (and other traffic is not), udp 4500 is NAT'ed
I guess this might be default behaviour, thing is that it used to work when it was set up as a route based easy vpn.
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.
can I force an IPSEC L2L tunnel to use NAT-T encapsulation no matter what? Automatic detection says none of the endpoints are behind NAT. I know I can disable it by the "crypto map XXX set nat-t-disable" command, but I want the exact opposite.
I have a very strange issue where asynchronos routing is making my life as a technician very hard.
A side question; Can I do something about an ISP that is policy-base-routing its ESP traffic (and/or translating it)?
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.
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;
! Denies vpn interesting traffic but permits all otherip access-list extended NAT-Trafficdeny ip 172.19.191.0 0.0.0.255 172.16.0.0 0.3.255.255deny ip 172.19.191.0 0.0.0.255 10.0.0.0 0.255.255.255deny ip 172.19.191.0 0.0.0.255 192.168.128.0
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.
