Cisco WAN :: 2941 GRE Tunnel Setup ( Bridging Interfaces )
Oct 1, 2012
I have two Cisco 2941's going over a IPSEC VPN. I need to push the same network over this connection. For example i need 192.168.255.0 / 25 on my side and i need to plug in a laptop on the far end 2941 with the same network. I have built GRE tunnels before and i found a configuration online to brdige interfaces over a GRE tunnel.
when i get to adding the bridging to the configuration which i will show below i get an error. Please see below. Also when i try to add the same briding command on the GRE tunnel which is needed it doesnt show the bridging command as being available. The Cisco 2941's are both using version: mwr 2941-iprank9-mz.124-20.MRb1.bin.As i stated the only end result i need is to be able to configure a path from point A and B and have the same network on each end.

Any difference between these (2) mobile wireless router models?
MWR-2941-DC
MWR-2941-DC-A
I can only find mention of MWR-2941-DC-A in Cisco's product documentation.

I have this setup at home and I can't make wireless bridging to work with two WR740N routers.I tried 3 online tutorials and none of them worked
R1,R2,R3 = routers
The main router "R1" Is setup like this :
IP Address 192.168.100.1
DHCP enabled 192.168.100.120 - 192.168.100.150
Gateway 192.168.100.1

I want to implement QoS on our Core router but the core router makes use of GRE Tunnels to remote branch locations.so far all QoS techniques i want to use cannot be implemented using tunnel interfaces.
the core router is a cisco 7604 router with IOS version 12.2 (33)SRE while the remote locations have ISRs (2821).
Which QoS technique to use with respect to GRE Tunnels as there are times of congestion due to heavy network traffic to those remote locations.

We have just installed our first 2951 router, and were suprised to see in our Netflow collector that Tunnel interfaces appeared even though we did not configure any, I have seen other posts talking about PIM tunnel when using Multicast, but we dont use multicast and the tunnel is GRE questions are, where do these interfaces come from? how do they pick up an IP address? can we shut them down?

So in our DMVPN network, we have this Cisco 3845 hub router that is connected via a DS3 to the Internet, and our spoke sites usually have a broadband connection that typically have a maximum of 1Mbps upload capacity. We are getting ready to add a few more sites to our network that are connected to the Internet with 10Mbps upload speeds (and 50Mbps download). Spoke site routers are usually 800 series ISRs. We have seen spikes of 8-10Mbps on the hub router so far. So the question is that a site with 10Mbps upload speed transmit to the full capacity over a DMVPN tunnel or is it limited by other factors? What are those factors?

I have two MWR 2941's in a lab environment awaiting deployment in a SAToP environment. They are both running the latest IOS, mwr2941-adviprank9-mz.151-1.MR3.bin. After being up for about 4 days they both stop responding to telnet attempts. I do not get a reject message - it just goes to a blank secreen with a flashing cursor. The only way to fix it is to reboot. I read that an older IOS had a similar bug on the MWR1941 but I cannot find anything about the 2941 having issues such as this.

We got a new CISCO 2941 MWR router shipped with the “mwr2941-adviprank9-mz.122-33.MRA.bin” image .I am not able to configure the Ethernet service OAM(CFM) . We need to configure a outward domain and outward MEP.The system is not allowing me to configure a outward MEP. There seems to be no option to configure an outward MEP. I am successfully able to configure inward domain and inward MEP but this does not fit in our setup as we want CCM to be send outwards .

I am using a CISCO 2941 DC-A router,For the PPP testing.I was using GL card from the GL communications.In the case of GL card it supports this below Feature"In MLPPP Simulation, NCP can be configured to send Packets over PPP links in the bundle or on the MLPPP bundle."My query Is in the Cisco Router 2941-DC-A,Is their support for sending NCP over PPP in the case of Multilink(MLPPP).Because I found out that in the case of MLPPP the Cisco router sends NCP packets over MLPPP only. How to configure the cisco router to send NCP packets over PPP in case of MLPPP.?

One of my customer has raised a new requirement for implementation of short sequence number format support in PPP multilink header for Cisco MWR 2941 E1/T1 serial interface, whereas router is supporting long sequence number format.here is the output of "debug ppp negotiation" command:-Currently in the MWR debugging logs we can see that by default MWR is sending long sequence header format as below
*Mar 13 01:32:55.438: Se0/2:0 LCP: O CONFREQ [REQsent] id 238 len 25
*Mar 13 01:32:55.438: Se0/2:0 LCP: MagicNumber 0x26CDF693 (0x050626CDF693)

Is it possible to set up a vpn tunnel on a 1721 router that uses the following ios:

I thought I had read somewhere that tunnels were not supported on the 1700s but wanted to make sure. If they are I would like to know if they are supported in the above ios.

I just joined this company and they already ad a VPN to one of their partners that provides them access to some resources. We have now added a 2nd location but the partner wouldnt allow a 2nd VPN tunnel so the decision was made to give the new location a ASA5505 to tunnel thru the main office to access the resources at the partners site.Using ASDM i believe i was able to setup the tunnel to the main office but there is no resource there to use. Now i'm stuck and i do not know what to do to get to the partner site

how to setup a both ends of an IPSEC VPN tunnel using a software client such as shrewsoft vpn and an 800 series router?
I've tried following the instructions on cisco's site, but I don't really understand which interface I should use? Dialer, VLAN1 or UnNumbered to a Loopback?
I'm OK with most basic features of the router, but never had any luck with VPNs?

I am trying to setup a vpn tunnel on my AG241 router but not having too much luck. I am not on a static ip, i sort of get the feeling that as long as i know the current external ip address i should be able to get through to my xp machine with the shares on it.

I have a Cisco RV220W updated to latest firmware 1.0.4.17. I have been trying to get a VPN setup for the past few days without success. We had a test VPN up and running previously, but when we changed the IP's and secret key to connect the live VPN tunnel it failed and we haven't been able to get it working since.We have deleted both ends, rebuilt them probably 6 times each. We have changed secret keys, tried 3DES, AES, and AES256 encryptions with SHA-1. All the internal IP settings are correct :IE 192.168.1.1/24 or 192.168.1.1 255.255.255.0,External IP's are right, only oddball thing here is one of the external IP's is assigned by DHCP and is a /22 although the previous tunnel worked with the same ISP.

I am in need to setup a VPN tunnel to a vendors hosted network for AD authentication.To prevent RFC1918 Address overlap we are trying to NAT into a VPN Transit Network.I was given 209.235.17.232/19 and need to NAT these addresses:
209.235.17.233 <> 172.20.0.42
209.235.17.234 <> 172.20.0.43
The vendor is using 209.235.17.224/29 and NAT'ing to some 10.122.xx.xx addresses.
The Phase 1 requirements are:
Pre-Shared DH-Group2-AES256-SHA1 86400 seconds
The Phase 2 requirements are:
NOPFS-AES256-SHA1 3600 seconds
I have many l2l VPN tunnels configured using esp-3des esp-sha-hmac This is what I have configured on my ASA:
static (INSIDE,OUTSIDE) 209.235.17.233 172.20.0.42 netmask 255.255.255.255
static (INSIDE,OUTSIDE) 209.235.17.234 172.20.0.43 netmask 255.255.255.255
access-list VPN-TO-JIVE extended permit ip 209.235.17.232 255.255.255.248 209.235.17.224 255.255.255.248
access-list VPN-TO-JIVE extended permit ip 209.235.17.224 255.255.255.248 209.235.17.232 255.255.255.248
[code].....
Currently my side is trying to initiate the tunnel, but we are getting this message:
15 IKE Peer: 65.168.255.157
Type : user Role : initiator
Rekey : no State : MM_WAIT_MSG2
I am configuring the transit network for the tunnel properly or performing the NAT for my 2 devices.I am still trying to determine what device the Vendor has on their end.

We are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router. I am attempting to setup a GRE tunnel over IPsec back to the main office. The main office consists of a PIX515, a 2821 router, and a 2921 router.
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices. The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well. The default route is to use the ASA. We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515. Right now I am not able to get the tunnel setup. It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls. I will show the output of that command below.
Main Office The external address 198.40.227.50. The loopback address 10.254.10.6 The tunnel address 10.2.60.1
Offsite Datacenter The external address 198.40.254.178 The loopback address 10.254.60.6 The tunnel address 10.2.60.2
The main office PIX515 Config :

I'm trying to setup a VPN Tunnel between RV082 and WRV200.The RV082 has an static IP, the WRV200 has a dynamic IP. I have to Dyndns.org in the WRV200.I have setup the RV082 tunel auth like: Dynamic IP + email.In the WRV200 I setup the hostname with the username, and the domain with the domain part of domain entered in the RV082.In the RV082 VPN Log I got: Initial Aggressive Mode message from 11.22.33.44 but no (wildcard) connection has been configured.It seems to be working the IPSEC setup but the RV082 does not accept the connection because of a missmatch in the Remote Security Gateway Type parameter in the RV082.

i'm using an rv220W and i whant to know if is it possible to assign vpn traffic to a vlan when i setup an ipsec tunnel?
example:
Im using different vlans on my rv220W.
Vlan 10: engineers (ex: 192.168.1.0/27) no intervlan routing
Vlan20: sales (ex: 10.0.123.0/24) no intervlan routing
This is what i need: - An engineer is on the road and when he makes a ipsec vpn connection => assignd to the vlan "engineers" so he can access the server/pc's in that vlan.and when someone from the sales group starts a vpn connection he needs to be in the vlan "sales" so he can access his pc/data,...

I'm trying to set up a VPN tunnel between a Linux machine and a RVS4000 at a remote site (served via satellite connection). After many efforts, I finally succeeded (based on Openswan). However, while PINGing is OK, big packets (from the RVS4000 LAN to the Linux box) arrive corrupted.
I lowered the WAN MTU, with no success. What finally did the trick is to lower the MTU at the RVS4000 LAN interface. Since this is not possible via the Web I/F, I did it via telnet ("ifconfig eth0 mtu 1400"). However, this change is lost after router reboot. How can I make the LAN MTU setting permanent?

How can I set up a Cisco 831 router (branch location) so that it will accept inbound VPN Client connections and initiate a site-to-site IPSec tunnel to our hub location that uses a VPN 3005 Concentrator? I could get the tunnel to work by configuring it in a dynamic crypto map but interesting traffic on the Cisco 831 side would not bring the tunnel up.
