Cisco Routers :: Site-to-site VPN From SRP527W (dynamic IP) To ASA 5505 (Static)

Sep 6, 2011

I have an ASA5505 running which is on a static IP. I have just got an SRP527W for a remote worker and want to create a site-to-site VPN into the ASA. I have a number of other router of non-cisco brand which just all dial-in and connect no problem.
On other routers I have been abloe to specify the DDNS hostname in the VPN setup so that the ASA can identify it. I'm not sure how I setup the SRP527 to connect to the ASA.

Cisco Routers :: RV180W Site To Site VPN Static On One End Dynamic

Mar 22, 2013

I am having a heck of a time configuring 2 RV180W's to establish an IPSEC VPN tunnel.  I have some experience at this with other Cisco products (RV042/082) but I can't get these beasties to cooperate.One RV180W is at a client's office and there are to be 1x RV180W and 1x RV120W located at 2 employee's residences.The office has a Static IP and the homes have dymamic IP.I figured I would config the units in the homes to be initators and connect to the office where the static IP is.  This is failing for me so far. Any example (screenshot?) of a config where this is working?  The firmware on the RV180W's I am trying to configure first are current.I even tried testing from my office (where I have multiple static IPs available) from RV180W here to RV180W at client's office (static at both ends) and I can't get a tunnel to come up.  Obviously I am missing the boat at some point in the setup.

Cisco Routers :: Site-to-site VPN With Dynamic IP Addresses Using RV 120W

Mar 13, 2012

I want to connect two sites through a VPN tunnel, such that each machine can access all others, regardless of which site they're located.
The two sites have a VDSL connexion with dynamic public IP addresses. Unfortunately, our ISP does not offer static IP addresses with VDSL connexions.
I plan to do the following : install two RV 120W routers, one at each site, right after the VDSL modemconfigure the modems in bridge mode, such that the 120Ws get directly the WAN IP address and trafficuse DynDNS to assign domain names ( and to each siteassign different subnets to each site (ie 192.168.1/24 for site 1 and 192.168.2/24 for site 2)configure a VPN tunnel in gateway mode using the FQDN ( and of each site on both routers, with corresponding remote subnets

Cisco Routers :: RV042 Site To Site VPN With Dynamic IP?

Nov 28, 2012

I recently bought two RV042s to create a site to site VPN for a client.  I have several of these setups installed at other locations but this is the first version 3 hardware I've used.It seems like the dynamic IP functionality of the VPN setup may not be working correctly.  I've verified all settings on each router match and have deleted/recreated the setup several times just to make sure.  Here's the logs from the router with a static IP.
Nov 29 06:49:51 2012 VPN Log (g2gips0): deleting connection 
Nov 29 06:49:51 2012 VPN Log added connection description (g2gips0) 
Nov 29 06:49:51 2012 VPN Log listening for IKE messages 
Nov 29 06:49:51 2012 VPN Log forgetting secrets 
Nov 29 06:49:51 2012 VPN Log loading secrets from '/etc/ipsec.d/ipsec.secrets' 
Nov 29 06:49:51 2012 VPN Log (g2gips0): cannot initiate connection without knowing peer IP address 
Nov 29 06:49:51 2012 VPN Log (g2gips0): cannot initiate connection without knowing peer IP address 
I've tried both dynamic IP + email and dynamic IP + FQDN to authenticate the router using the dynamic IP and both give the same error as above.I did a firmware update hoping to fix PPPoE which seemed to be broken with a Netopia modem in bridge mode so both routers are on the latest firmware, v4.2.1.02.

Cisco Routers :: RV200W Site-to-site Vpn With Dynamic Ip

Dec 30, 2012

I've got a problem with establishing VPN site-to site tunnel from client (Cisco 1801/871) with dynamic ip addres. My central site using static address but remote site(s) has dynamic IP, and I don't want using dyndns etc. ... just simple any ip client connecting to central site. It had worked very well with Cisco 1812 which was changed for RV220W. Any other tunnels between two static sites works fine with RV220W.

Cisco VPN :: ASA 8.4 Fixed IP Site - Site VPN Remote Has Dynamic IP?

I am trying to get my head round configuring an ASA with V8.4 code where things have changed especially NAT.In earlier ASA 7/8.x code I belive the crypto map below would have allowed a properly configured remote router to connect irrespective of its WAN IP
I am struggling to get my head round how I achieve the same in ASA V8.4 . I have searched the web and found plenty of examples for earlier code but specificlly am trying to learn about how to achieve it with v8.4

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 Routers :: RV110W Does Not Support Site-to-site VPN

Jun 14, 2011

I bought RV110W Small Business Router yesterday but I cannot find manual and any support sources neither on supplied CD nor on Cisco web page - where can I find these sources? This devices does not have any product page on the web!
Warning: RV110W does not support site-to-site VPN. RV110W is probably the only one RV Cisco Small Business Router, which does not support even one Site-to-Site VPN tunnel. Router supports client-to-server IPsec (only by QuickVPN software!) and PPTP VPN, full IP6 support for LAN and WAN and fairly usefull firewall and admin tools similar to RV120W.

I am building a site to site VPN from our headquarters to a customer. I am using an ASA 5520. The customer is using Cisco 3945 routers. The customer has two VPN termination points. The customer requests that we make one of their termination points the primary VPN connection and make the other termination point the backup in the event that the primary VPN fails. How do I configure this on the ASA? Does the below configuration fulfill this goal?

Cisco VPN :: ASA 5520 / Site To Site Failover VPN Connection And Routing?

Apr 8, 2013

We have 3 sites, with a Cisco ASA 5520 at each location.
HQ (Headquarters)              internal network:,
DR (Disaster Recovery)       internal network:
BO (Branch Office)               internal network:
HQ and DR have a 100Mbps permanent MPLS link between each other.Branch Office has a Site 2 Site VPN connection to HQ. If it fails, it establishes a Site 2 Site VPN connection to DR. This works perfectly.Now the routing issue... There is no route to the BO in the routing table at HQ/DR. The default gateway is used to reach the BO and that works for HQ when the VPN is between HQ/BO. If the VPN fails over to DR/BO, HQ can't reach BO anymore.I need to have some kind of conditional route injection from the ASA where the VPN is established. I was considering a tracked static route, but I was wondering if the S2S VPN itself has a functionality to do so. I thought the Reverse Route Injection was it but it's enabled on our crypto map and doesn't seem to work...

Cisco VPN :: 5520 And 5505 Site-To-Site Tunnel Between Two ASA

Apr 2, 2013

I am using the Site to Site Wizard on an ASA 5520 and ASA 5505 from the ADSM. Both are using 8.4(5). When you create the configurations. Do you have to follow up the wizard configurations with manual ACL's to allow for traffic from each connected subnet to talk to each other? Or are they automatically generated in the configuration file? Have not been to school yet to properly understand how to create the VPN tunnels from the CLI and what to look for.

Cisco VPN :: 5520 - Site To Site Vpn Failing Randomly

Aug 4, 2011

I have a pair of ASA 5520s configured in failover mode that also acts as VPN endpoint for about 25+ site to site ipsec VPNs.  Of the 25 sites, 2 sites consistantly are having VPN issues while the other sites never have this issue. 
For example, at a branch office the network is, and at the headquarter the ASA has an interface with network  VPNs are setup to tunnel all traffic destined to the headquarter network and a couple of other networks with public IP addresses not directly connected to the ASA. 
When the issue occurs, I can ping anything in the or the range across the VPN, but I cannot ping anything in the public IP range.  ASDM reports that the tunnel is up.  Restarting the routers at the branch offices do not work.
So far, I have been able to resolve the issue whenever it occurs by doing the following, however this issue happening more and more frequently:
first, try killing the VPN tunnel and wait for the router and ASA to re-establish the tunnel, sometime that works.  If that doesn't work, I would failover to the standby ASA.  Sometime even that doesn't work, then I have to reload the standby ASA before I failover to it.
  All these site to site VPNs are setup the same way for the same purpose (to tunnel ad/exchange traffic), and this issue only happens to 2 of the branch offices which are using different ISPs - I even switched one of the 2 offices to a different ISP and router recently - still have the same issue.
