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 VPN :: ASA 5505 / Dynamic-to-Static Site To Site VPN?

Nov 7, 2012

I have some sites already connected with ASA 5505 site to site VPN with both end static IP.  Normally, all traffic can come across without any problem.  Even I used "management-access inside" for both ASA.Now I have a new office with only ADSL pppoe connection.  I used easy VPN to connect from Site B:remote dynamic IP site to SiteA:static IP with similar example of this: [URL]

All my 5505 ASA are running 8.4(4)1
Site A - Static IP
Site B - dynamic IP with pppoe connection.
After EasyVPN connected, i do not know how do I remote manangment from site A lan to site B 5505 ASA?

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

Cisco VPN :: Reverse Route Injection On ASA5510 Site-to-site

Jul 29, 2011

We have two ASA5510's connected to two different ISP's and both able to initiate a site-site IPsec connection to a remote site. Depending on the state of the ISP's either ASA may initiate this VPN.We use Reverse Route Injection into OSPF for VPN clients and it works fine with the route being distributed when a client connects and disappearing when there are no clients.So we thought we'd try it for our site-site VPN's. Unfortunately when we enable Reverse Route Injection the routes are distributed regardless of whether the VPN is up or not, so if one ASA has initiated a VPN it's reverse route is distributed (which is what we want) but the other ASA also distributes a route for it's non-existent VPN. The result is that our gateway routers see two OSPF routes and can't ascertain which route is actually up.
Is there any way to distribute the route using Reverse Route Injection (or any other method) only when a site-site VPN is actually up? For various reasons we can't use BGP or other gateway routing protocols.Our ASA5510 are currently running IOS 8.2(1)

Cisco VPN :: Network-access Between ASA5505 And ASA5510 (site-to-site)

May 9, 2011

we set up a site-to-site-vpn between a 5505 and a 5510 (both asa8.3.1). We configured both sides using the VPN-Wizard in the ASDM. When we try to ping from the network behind the 5505 ( to any host behind the 5510 ( the tunnel gets established but the ping doesn't get trough. After that we tried to connect via RDP to any host behind the 5510 and it worked well (same with ssh, telnet,vnc etc.). Now we want to map a network-share on a 2008-Server behind the 5510 but it's not working. In the ASDM-Log I see some "denied by inside-access in"-messages for the ports 139 and 445. Isn't it right that the whole traffic in the vpn-tunnel bypasses the acl? Even if we open both ports we can't connect to the network-share?

Cisco VPN :: Multiple Site To Site IPSec Tunnels To One ASA5510

Dec 4, 2012

Question on ASA VPN tunnels. I have one ASA 5510 in our corporate office, I have two subnets in our corporate office that are configured in the ASA in a Object group. I have a site to site IPSEC tunnel already up and that has been working. I am trying to set up another site to site IPSEC tunnel to a different location that will need to be setup to access the same two subnets. I'm not sure if this can be setup or not, I think I had a problem with setting up two tunnels that were trying to connect to the same subnet but that was between the same two ASA's. Anyways the new tunnel to a new site is not coming up and I want to make sure it is not the subnet issue. The current working tunnel is between two ASA 5510's, the new tunnel we are trying to build is between the ASA and a Sonicwall firewall.

Cisco VPN :: Configure Site-to-site VPN Using 881 Router On End And Connecting To ASA5510?

I need to configure a site-to-site VPN using a Cisco 881 router on my end and connecting to an ASA5510 on my suppliers end.Our supplier has configured their end and I do not have access to their configuration.
They told us we have to NAT all inside address' to a single address ( as this is the only one they will let through their firewall/tunnel.I know how to set up the VPN but not too sure how to set up the NAT part.
My sanatized config is attached. The code I am using to NAT my inside network to the single address, and send all traffic accross the VPN tunnel as this address is correct? With the router running this config the VPN tunnel does not connect.

Cisco VPN :: ASA5510 Site-to-Site VPN Same LAN Subnets

Jan 21, 2013

I am setting up a VPN between my client and their owner, in order for the owner to access ressources at my clients site.Unfortunatly their owner already has an VPN connection to another site with the same subnet as the one on my clients site.I have setup a policy NAT to translate my clients internal LAN to a "NAT" LAN, and i can ping from my clients LAN to their owners LAN, but their owner can not reach any ressources at my clients LAN.
My client has a ASA5510 with a base license, but their owner has their firewall and routing "leased" or something like that, it actually was their ISP who configured the VPN settings. That means of course that i have very limited (no) access to the other site's firewall and I actually even dont know make and model of it.
And last but not least, the subnet the Owner needs to access is on my clients Core Switch and the ASA has an internal route to it.I have pasted in a interresting parts of the ASA config here below, the displayed subnets are not the real ones . [code]
