Cisco VPN :: 2811 MGRE Tunnel Is Not Establishing Between Two Routers
Aug 5, 2012
A multipoint GRE (mGRE) and IPSec tunnel is built between two routers. The topology of the device is briefied below:Configuration in End Router: This is a cisco 2811 router. Amoung 2 ethernet interface ,one is using for LAN and one is for WAN. In WAN part , we have configured mGRE (Tunnel1 and Tunnel 2)by creating sub-interface of the router. From the interface ,we terminating the link to MPLS cloud from there its pointing towards our core router.From End router we are advertising the path through EIGRP and from the cloud BGP advertisied to the core router.[code]
Have a 6500 using the vpn spa with ipsec tunnels. The plan is to migrate all tunnels over to DMVPN. When we configured the mGRE tunnel and bring it up, all the other tunnels slowly drop. As soon as we shutdown the mGRE tunnel, all other tunnels come up. We have a tunnel key set for the mGRE tunnel. The only limitations I could find were that we only source 1 mGRE tunnel from an interface, I could not find anything about sharing and interface with p3p tunnels. Is it possible to source an mGRE tunnel and p3p tunnel from the same interface?
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.
I have recently bought two CISCO routers RV220W for our main and brach office mainly for VPN tunneling. I didnt know they are routers only not modems. so I have set it up using BT 2wire Router as modem only.
I have successfuly setup the routers and manage to establish the VPN tunneling between two routers. AS bt doesnt give static WAN IP address so I have used Dyndns which works fine. although I have 5 static ip address which cannot be used for WAN unless i cahnge to one IP address even then BT tech said it will not work.
when I created the tunnel i could ping both servers with their IP only not with the names. I can ping them fine locally. I could also see the network from branch office to main office but not from main office to branch office. today when I restarted the server I cannot ping both server i mean vice versa but VPN tunnel is established. now I cannot see the network from branch office to main office as well.
Both sites running windows server 2008 standard. main office server has 6 NIC cards two wwith public and three with private ip addresses, its also runing Terminal server, exchange, file etc. the branch office has two NIC card one with private and one with public ip. Intially I could establish the VPN tunnel as the network range was same on both sites so I changed one in th e10.0.0.0 range other in 192.168.1.0 range and VPN tunnel was established straightaway.
As soon as the VPN tunnel was created I manage to creat an external trust without any problems and both servers are added in each other forward zones as name servers.
in the main office the fues went off and I had to re-start the router and now the VPN tunnel is not establishing, mainly the error is ISAKMP-SA Expired I will paste the log of both routers below
1. How to Clear Old or Existing Security Associations (Tunnels) on RV220W 2. how to fix the problem where I can ping the server with their IP as well as domain names ? 3. how to set it up so that both sides can see the network resources as well as access it ? 4. how to set it up so if the staff in branch office wants to log on the domain in main office he can simply do it as he does it in his office.
I'm seeing on an IOS VPN Tunnel interface which keeps going down and then back up...
We have a Cisco 2811 acting as a VPN Hub router on the backbone, which connects to various client sites over VPN. Of the 7 VPNs configured so 6 work well and are generally trouble free. The VPN interface on the other VPN keeps going down ,multiple times throughout the day, just recently the client has been noticing loss of connectivity. The remote router is managed over the VPN so there is always some kind of traffic over it.

ISP on each circuit cannot provide more than 3MB, so soon will get three circuit each of 3MB. ISP recommends to terminate all the links on Layer2 switch and have a trunk to the Router. I need all experts opinion on this proposed setup. We currently got 2811 with two GigaEthernet ports. We plan to have three GRE over IPSEC Tunnels (One tunnel for each circuit) to load balance/load Share/redundancy.
We have two Cisco 2811 Routers setup with a GRE tunnel that we would like to constrain the bandwidth on to replicate a satellite connectinon of 400 kbits. We tried the bandwidth command 400, but from what I understand that is only for routing metrics and not actual speed of the interface.
We are facing network heavy and slow performance at one of our remote site, we are using Cisco2800 series router with same IOS on either of the sites.Our WAN network is running on BGP with EIGRP configured and tunnels were configured on either of the sites. As part of the testing I have removed the tunnel to see the performance was ok from Head office to remote branch and the WAN network is getting heavy and slow down when we put the tunnel back in hub and spoke.

I am using a Cisco RV110W (Firmware 1.2.09) in a branch and I would like to create a VPN Tunnel to another site that has a Cisco RV042 (firmware v4.2.1.02)
What would be the correct Configuration? the current configuration I am using is
in the RV042 i am using
Check Enable Local Group Setup Local Security Gateway Type : IP Only IP Address : RV042 Pulbic IP address
I have a asa and Cisco 2811, needs to build a site-to-site ip sec tunnel between them. Due to a requirement need to encrypt inside traffic, i need to apply on the inside interfaces on both devices to build the tunnel.
I don't see a problem but just want to check if it would work on terminating on Inside interfaces on both ip sec peers.
We have a fixed IP address 3G data SIM which we intend to use as backup for our ADSL connectivity using a CISCO887VAG+7-K9 router. (We have previously implemented similar using the older CISCO887G-K9 router without any issues)
The problem is, we don't seem to be able to establish 3G connectivity with this new router. Our service provider assures us that the SIM card is active (although they have seen no connection attempts from us on their RADIUS server)
The router is running IOS version 15.1(4)M4 and the following is the relevant config we have used:
My company bought another company and moved them into our building. the company moved in but are on an entirely different network all together. wired separately, different domains.what i would like to do is be able to have them communicate with each other. have users on company A be able to use printers on company B's side of the network.
I live in a very rural location with very few high speed Internet options.Unlike a lot of others, i have a relative 1.5 miles away who does have a high speed internet connection and is willing to up their package and split the cost with me. We've each gone up on our roofs with binoculars and confirmed we have a good line of sight, so setting up a long range point-to-point connection is what I am looking to do.
I already have a Tranzeo CPQ (TR6) to place on my roof (destination), so I just need something on my relative's house (source) to connect with.My initial thought was just to pick up another Tranzeo unit like mine from eBay for $100, but after doing some research, it appears the Tranzeo unit I have can only act as a client at the destination, so placing one at the source won't work ... or am I wrong here?
I have used my Tranzeo in the past over a much shorter distance (<800ft) to link up with a consumer Belkin N router, and it worked fine. For this new setup,I'm looking to connect the source's long range unit into my relative's router, then connect the Tranzeo on my roof to my router's WAN port.This way, my router will receive a DHCP address from my relatives router.
I have two routers 2811, which set ntp client. Different versions of the IOS, other devices are working properly. My routers takes time to ntp with other router,which take time from ntp server.
Attached are the configuration files for the devices in question. I have a 5510 that belongs to my company and a 5505 that belongs to another company. The 5505 sits behind the 5510 and is able to connect to the Internet. My thought was that VPN access should be a trivial pursuit. I was planning on just giving the admin at the remote office the public IP address that's natted to the 5505 and all would be good.
How to set up a home network with 2 routers, where R1 acts as the DHCP server and R2 is basically a switch, connected LAN to LAN and everything is on the same subnet. Currently I have a different setup:Both routers have the DHCP server enabled and I connect R2's WAN port to R1 LAN. Therefore I have 2 subnets. Now my special requirement is that R2 is a DD-WRT router, which establishes a VPN connection to StrongVPN, so that all internet traffic via R2 is encrypted and goes through the StrongVPN server. Now my question:If I change my router setup to the same subnet, meaning R2 connects LAN to R1 LAN and I disable DHCP server on R2, will R2 still be able to establish the VPN connection?
I am having an issue with establishing L2L VPN with remote site. My side is cisco asa 5520 and other side is check point UTM-- tunnel is not up.just wnated to confirm on my sidde if the configuration is OK.al the parameters using are correct for both side. any issue with below conf ? default route is pointing to my next GW address is there additiona default is required for VPN ? to reach the remote LAN somthing like pointing to remote peer address.to give a brief idea front end device is router as GW wher in internet is terminated and other wan connections ASA is behind ther GW rtr and outside int of asa and lan interface of GW rtr is having public ip. LAN switch is connected to ASA
What are the IPv6 anycast addresses using for?, are they some kind of broadcast? I have a router 2811 I'm configuring ipv6, do I need to use these addresses?
I'm at a FOX affiliate TV station, and in order to connect our EAS Device to the internet & Fox Splicer, I need to setup a Statio NAT, so we picked up an 1841 on eBay.
I've done a little configuration in HyperTerminal.
I've done these ip addresses:
FE0/0 10.1.10.13 this is the subnet our EAS device is on FE0/1 10.110.81.174 this is the subnet of the Fox Splicer.
I need to have NAT translate 10.1.10.11 to 10.110.81.170 and I also need to set a route for 10.110.81.0/24 pointing to 10.110.81.161
The Exchange can receieve emails but it will not send them. It cannot make connection to any of the smart hosts on port 25 or can't even send mail using DNS. When I run telnet my.smarthost.com 25 it will not connect but if I run that from the router then it connects fine.

I have installed a new 2901 router with the IOS version 15 code (c2900-universalk9-mz.SPA.152-3.T.bin). I have a template config that I have created for my remote VPN routers that I have been using on 2811 routers with version 12.4 (c2800nm-advipservicesk9-mz.124-24.T1.bin).I do have the securityk9 active on the 2901 software

Issue is when I do a "show crypto session" the GRE tunnels session status read down on the 2901 router but on the 2811 session reads up-active. Everything is working and I am routing over the GRE Tunnels.
I would like to set up a POTS Dial connection between 2 Cisco routers, using the modem card WIC-1AM-V2. I'd like to use this as an out-of-band connection to a remote site, if the primary internet connection fails. So, this setup will only be used in one direction, 1 router placing calls, the other one receiving calls.Here's my config of the receiving router:
chat-script dial "" ATZ AT OK "ATX3D T" ATS0=8 TIMEOUT 120 CONNECT C interface Async0/2/0 description out of band for network no ip address encapsulation slip async mode interactive line 0/2/0 session-timeout 5 absolute-timeout 10 script connection dial login local modem InOut transport input all escape-character BREAK autoselect ppp stopbits 1 speed 115200 flowcontrol hardware
[code]....
This config is working fine, when dialing in via a Windows Hyperterminal Dial connection. After a while of dialing I get the login prompt of the router.Now I want to have a router placing calls instead of a Windows Server. I can't figure out how to tell a router to place calls to a POTS phone number.
I have 100 mbps fiber connection. I bought 320N today I bought 320N and here is the problem:
We have a switch in the building. I am getting connection via CAT5. So I choosed "Use as WAN Port" from Ethernet settings. There is not much you can do here. I just used PPPoE and connected internet without any problem. The problem is I am only getting 32mbps. When I connect CAT5 cable directly to my computer I am getting 92mbps.
Maybe WAG320N is not establishing a full duplex connection.
My ISP (OTEnet, Greece) offers IPv6 connectivity in the form of dual-stack IPv4/IPv6 with the requirement that the router supports DHCPv6 Prefix Delegation for establishing an IPv6 connection.Using other routers (Cisco 887W, DrayTek Vigor2130n), I have established an IPv4/IPv6 connection but I am unable to do so with the EA4500. As a matter of fact, when I have the "IPv6 - Automatic" option enabled the router not only cannot obtain an IPv6 prefix from the ISP but it gets stuck in the connection attempt and never obtains an IPv4 or an IPv6 address. I have to disable the IPv6 option in order to simply establish an IPv4-only connection without problems.So, my questions are:
1. Does the latest (2.1.38.38880) firmware support dual-stack IPv6 and DHCPv6 Prefix Delegation?
2. If the router cannot negotiate an IPv6 connection why is it not establishing an IPv4 connection only but gets stuck in the process?
I have a gateway to gateway vpn (home-office) working fine for almost an year btw 2 wrvs4400n routers, This morning, the VPN tunnel was down. I clicked "Connect" from the web based interface, but it does not reconnect.
I tried setting up a new tunnel using the VPN setup wizard, but it says it can't connect to the remote router. Which is strange, since I can ping there normally.
Is it possible to have a site-to-site IPSEC tunnel between 2 identical RV110W routers?I basically want one of them to initiate a secure tunnel with the second so that computers from one router subnet see the computers from the other router subnet.
the RV110W IPSEC site-to-site tunnel, are there necessary 2 x public IPs for it to work, or only 1 public IP is enough? [code]If it works with 1 public ip, the "CLIENT" RV110W configuration should be straightforward (in Advanced VPN SetupRemote Endpoint i fill in the dyndns address?), but how do i setup "HOST" RV110W?
Is it possible to configure an IPSEC GRE tunnel with RIP on an SRP527w? I see RIP, GRE & IPSEC are all possible.. But I'm not sure about them all together securing the GRE tunnel??
I basically want to do this with the SRW routers not native IOS. Single head end hub & spoke.
