Cisco VPN :: 5520 / IPSec VPN Won't Initiate From Remote Site

Sep 8, 2012

I have a site-to-site VPN configured between a 5520 at our data center, and a 1700 at a client's site for site-to-site connectivity.  What I've noticed is, is that the VPN can only initiate from my Data Center, never from the client router.  I can telnet into the router and start a telnet session sourced from the "inside" interface and it fails, yet I can see the NAT translations get created in the state table that should match the crypto-map.  However, if I ping a host on the inside of the remote LAN from my workstation (behind the 5520) to bring the tunnel up, and run the exact same command on the client router once the tunnel is up, it works.  Right now I have a continuous ping running from my workstation to keep the tunnel up, but obviously that's not the best solution
 
I had to modify this config to NAT the LAN addresses at the client to a non-overlapping subnet, so anything coming from 128.1.0.0/16 should be NAT'd to 192.168.105.[50-200]/24.  I've also got two static NATs for inbound access from the data center and those seem to work fine.

Cisco VPN :: Establish Site To Site IPSec Tunnel Between ASA 5520 And 3030?

Feb 17, 2013

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.

Cisco WAN :: 2911 - Site-to-site IPsec Vpn / Unable To Ping Remote Network

Apr 3, 2013

I have two Cisco routers - 2911 in HQ and RV180 in branch office. Because in HQ LAN network I have some development servers, to which guys from branch office need to have acces, I decided to setup VPN site-to-site between HQ and branch office. Everything went quite smoothly, on both devices I see, that ipsec connection is established. Unfortunately I am not able to ping resources from one network to other one and vice versa. Below is the configuration of 2911 router (I skipped som unimportant (imho) configuration directives) :

Cisco VPN :: Remote Site Redundancy IPSEC Between 2911 And ASA

Nov 11, 2012

We already have IPSEC VPN connectivity established between sites but would like to introduce some resilience/redundancy at a remote site.
 
Site A has an ASA with one internet circuit.
 
Site B has a Cisco 2911 with one internet circuit and we have established site-to-site IPSEC VPN connectivity between the 2911 and the ASA.
 
Prior to getting the new internet circuit, Site B had a Cisco 877 with an ADSL line which are still available but aren’t currently in use.
 
The internet circuit at Site B has dropped a few times recently so we would like to make use of the ADSL circuit (and potentially the 877 router too) as a backup.
 
We thought about running HSRP between the 877 and 2911 routers at Site B and, in the event of a failure of the router or internet circuit, traffic would failover to the 877 and ADSL.
 
However, how would Site A detect the failure? Can we simply rely on Dead Peer Detection and list the public IP address of the internet circuit at Site B first with the public IP address used on the ADSL line second in the list on the ASA? What would happen in a failover scenario and, just as important, when service was restored – I’m not sure DPD would handle that aspect correctly?
 
I’ve read briefly elsewhere that GRE might be best to use in this scenario – but I can’t use GRE on the ASA. I have an L3 switch behind the ASA which I may be able to make use of? But I don’t want to disrupt the existing IPSEC VPN connectivity already established between the ASA and the 2911.   Can I keep IPSEC between the ASA and 2911 but then run GRE between the L3 switch and the 2911? If so, how would this best be achieved?  And how could I also introduce the 877 and ADSL line into things to achieve the neccessary redundancy?

Cisco VPN :: 5520 Controlling Remote Site Access Through LAN-to-LAN

Mar 19, 2013

We have 2 5520 ASA's working in an active/standby function at our central site. The remote agencies have control of their ASA's or other devices able to create VPN tunnels back to the central site. When a new remote agency wants to connect to our central site we assign them a network range that is routable on the central sites network.We ask that the remote agency NAT into the addresses we provided them.This way we are able to route back to them. We assign the interesting traffic and then they we start communicating by way of the tunnel.  
 
Since the central site can't control the traffic coming in on the site to site tunnel other than just defining the interesting traffic AND we aren't able to control the NAT on the remote end how can I put an access list on the central site ASA to allow only certain ports and IP's by way of access list?   Ultimately, I'm trying to limit traffic on the central site coming inbound to only allow traffic I want.  I tried applying a group policy to the lan2lan site to site tunnel, but it failed for some reason. It actually prevented all traffic. Can I apply a group policy to a site-to-site tunnel?  
 
I'm struggling here a bit as I don't have control of the remote end.   They can NAT whatever they want to an address in the range we assigned them.   The tunnels interesting traffic is set to full ip to the central site's destination.  The interesting traffic on the central site is set the same. However, on the central side...I want to limit that traffic to only certain ports by way of an acl.  If it is possible to assign a site-to-site tunnel a group policy and filtering is done in that method, can

Cisco VPN :: 5520 VPN Filtering And Access From Local To Remote Site

Cisco VPN :: ASA5505 - IP Address Pool In IPSec Client And Site-to-site VPN

Jul 10, 2012

We have a scenario where the Cisco ASA 5505 will be one end of a site-to-site VPN. The same ASA 5505 also allows Client VPN connection. The question is around IP pooling. If I assign a pool of IP's (192.168.1.20 - 192.168.1.30) for Client VPN connections - do I need to be sure that those same IP's are not used on the other side of site-to-site VPN ?

There could be PC's/Servers running 192.168.1.0/24 on the other side of site-to-site VPN. Would this cause an address conflict ?

I see that when I do this syntax in ASA: show crypto ipsec sa.They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505.

Cisco VPN :: 4500 Switch - Dot1q Tunneling Via PPTP IPSec VPN Site-to-site Tunnel?

Nov 28, 2012

I have a situation where the site-to-site tunnel is already established using PPTP IPSec VPN with non Cisco Gateways terminating the link on each end. These non Cisco Gateways do not support L2TP tunneling, and there is no plan to change them.Beyond the Gateways on both ends, we have a Cisco 4500 series switch. We need to forward the 802.1q tagged VLANs between the two sites. Is it possible to use 802.1Q tunneling in this case, going via a PPTP tunnel ?
 
Cisco's setup uses dot1q-tunnel over a L2protocol-tunnel to preserve the original client VLAN tagging, so does this mean that the only option we have is to setup a L2TP tunnel at the Cisco device endpoints, and have that tunnel go through the existing PPTP tunnel (established between the 2 non Cisco VPN Gateways) ?
