Cisco VPN :: ASA 5505 - Users Aren't Able To Reach Remote Network Through Site-to-site Tunnel
May 21, 2011
Remote-access users aren't able to reach our remote network through a site-to-site VPN tunnel between two ASA 5505's.
I've seen several threads about that here, I've run through the walkthrough at [URL] I've taken a stab at setting split tunnelling and nat exemption, but it seems I'm still missing something. Remote-access users can reach the main site, but not the remote site.
Remote-access (vpn-houston) uses 192.168.69.0/24.
The main site (houston) uses 10.0.0.0/24
The remote site (lugoff) uses 10.0.1.0/24

cisco products and am struggling getting a VPN going between an ASA 5505 and 5510. I have a VPN created (using the VPN wizward on both) and it shows the VPN is up, but I can't ping the remote site (from either side).

I have ASA 5505, i configured site to site vpn between central site and remote site and is working. Now the problem is we use remote site for troubleshooting purpose, so we need to create a tunnel from remote site to central site. I need to configure such a way that remote site can craete a tunnel to central site, but central site not able to create a tunnel, it just respond to remote site.

we have two ASA 5510s one in 8.4(4) and one in 8.2(5) in a site-to-site VPN setup. All internal traffic is working smoothly.Site/Subnet A: 192.160.0.0 - local (8.4(4)) Site/Subnet B: 192.260.0.0 - remote (8.2(5)) VPN Users: 192.160.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible.
Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise.There are also some weird NAT rules that I am not happy with that were created after I upgraded Site A ASA to 8.4
Site A internal: 192.160.x.x External: 55.55.555.201(main)/202(mail)
Site B (over site-to-site) is 192.260.x.x External: 66.66.666.54(all)
I pretty much just have the basic NAT rules for VPN, Email, Internet and the site-to-site.What do I need to add for the VPN to be able to access the site-to-site network?
Here is my NAT config:
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static VPN_Network VPN_Network no-proxy-arp route-lookup
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static DOMAIN_REMOTE DOMAIN_REMOTE no-proxy-arp route-lookup
!
object network DMZ_Network
nat (DMZ,Outside) dynamic interface
object network DOMAIN_LOCAL

We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.

It's been a long time since I played in Cisco CLI.Using a Cisco 506 Firewall 6.3(4) PDM 1.0?Problem is I created a site to site tunnnel with a vendor and since then our remote VPN does not work. Completely times out so I am sure I broke something in the crypto map or something similar.
Tunnel is policy 10 using access-list 101
Remote VPN is Policy 20

At the main site, I have 3 5508 WLCs each part of a mobility group (wlcMain-MG). In NCS, under "System/Mobility Groups" for each controller, I see each controller listed as "local" with the other Controllers listed with the group name "wlcMain-MG". None of the SSIDs are "anchored".
I have a new site with a 2500 series WLC that I would like to push out 2 SSIDs. This site contains two customers. One customer is the Main customer with the second customer leasing space.
I have the Cust2 WLAN at the remote site set to have traffic egress out of a local interface on the 2500 WLC (this traffic is then tunnelled back to their Main location via an ASA which houses the DHCP scope for that vlan). I can connect to this SSID, obtain an IP Address off the ASA and am tunnelling without issue.
For the Cust1 WLAN at the remote site, I would like to broadcast an SSID from the Main location on those same APs which are registered to the 2500. It is my understanding, that I anchor the SSID at the Main site and identically configure the SSID at the remote site. This will allow the end user to authenticate to the RADIUS server at the Main site and be placed upon the correct vlan (we are using DOT1x and dynamic vlans).
For my test, I am starting simple. I have created a test WLAN with no authentication. At the main site, on 5508 WLC3, I have created the test WLAN, and placed the interface into a low security vlan (call it VLAN-low). I have anchored this test WLAN to that controller. At the remote site, I have created the same WLAN (but placed it into the management interface for now - the VLAN-low does not exist at the remote site) and configured that WLAN to anchor back to the WLC3 at the main site. I am unable to obtain an IP address from the remote site. I have placed the remote site WLC in the wlcMain-MG as well. How close does the code need to be on the controllers - the 5508s are at 7.0.116.0 and the 2500 is at 7.0.220.0? What could I be missing?

I have a situation where I need to have remote users vpn into my ASA 5510 and then turn around and hit a site to site tunnel. Now when I am in our office I can hit the site to site vpn fine. When I am at home and vpn to the asa I can not get to the site to site resources. Do you see where my config is incorrect? result of the command: "show run"

I have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: [code]
After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. 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. [code]
All these remote networks are at the Main Site Clavister Firewall.

Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.

i have a client who needs to establish a VPN tunnel from his satellite office (Site A) to his corporate office (Site Z). His satellite office will have a single PC sitting behind the ASA. In addition, he needs to be able to VPN from his home (Site H) to Site A to access his PC.The first question I have is about the ASA 5505 and the various licensing options. I want to ensure that an ASA5505-BUN-K9 will be able to establish the site-to-site tunnel as well as allow him to use either the IPsec or SSL VPN client to connect from Site H to Site A. Secondly, I would like to verify that no special routing or configuration would need to take place in order to allow traffic not destined for Site Z (i.e., general web browsing or other traffic to any resource that is not part of the Site Z network) to go out his outside interface without specifically traversing the VPN tunnel (split tunneling?)Finally, if the client were to establish a VPN session from Site H to Site A, would that allow for him to connect directly into resources at Site Z without any special firewall security rules? Since the VPN session would come in on the outside interface, and the tunnel back to Site Z goes out on the same interface, would this constitute a split horizon scenario that would call for a more complex config, or will the ASA handle that automatically without issue?

I am using a Cisco ASA 5505 Here is a description of my topology.
Headquarters = 192.168.201.0
Client X = 172.16.0.0
Datacenter = 10.12.0.0
Site to Site Tunnels:
Headquarters ---> Datacenter
Datacenter ---> Client X
I want to ability for computers in the Headquarters subnet to access the Client X subnet.I have tried setting up a static route to push all traffic destin for 172.16.0.0 to the datacenter, but was unsuccessful. how I can route all 172.16.0.0 through the tunnel.I have tried ading a static route on my ASA but without success.

I do have a 5505 up and running, and passing data... url...Now I am trying to get a IPSEC VPN tunnel working.I actually have it up (IKE phase 1 & 2 both passed), but it is not sending/receiving data through the tunnel.
The networks concerned: name 10.0.0.0 Eventual (HQ Site behind Firewall)name 1.1.1.0 CFS (Public Network Gateway for Palo Alto Firewall - Firewall IP: 1.1.1.1)name 2.2.2.0 T1 (Remote site - Outside interface of 5505: 2.2.2.2)name 10.209.0.0 Local (Remote Network - internal interface of 5505: 10.20 9. 0.3) On a ping to the HQ network from behind the ASA, I get port map translation creation failed for icmp src inside:10.209.0.9 dst inside:10.0.0.33 (type 8, code 0)
I am suspecting that there is a NAT error and/or a lack of a static route for the rest of the 10.0.0.0 traffic, and that I may have to exempt/route the traffic for the HQ network (10.0.0.0), but I haven't been able to get the correct entries to make it work. [code]

I'm currently trying to configure a Site to Site tunnel between an IOS Router and an ASA 5505 running 9.1
When the private subnet of the IOS Router was 10.0.0.0/24 and the private subnet of the ASA was 172.16.1.0/24, it connected fine.
I'm now trying to set it up where both private networks are 10.0.0.0/24, and created network objects, edited the ACL for interesting traffic, and created the twice NAT translation rule, but the tunnels aren't coming up.
There is the IOS Router(R1) and the ASA(F2). In between them is one Internet posing router that is just set up to allow both sides to reach their WAN addresses.
R1 and F2 have private network (10.0.0.0/24) and need to communicate. Twice NAT can be done all on the ASA to allow this, but I must be doing something wrong. The way I understand it, is that the R1 should see the traffic coming from 10.51.0.0/24 and sending to that traffic. The ASA will take that traffic, and the inside network should see it come inbound as 10.50.0.0/24. So the F2 private network communicates with 10.50.0.0/24 and R1 private network sends traffic to 10.51.0.0/24.
I turned on "Debug crypto ipsec" and "debug crypto isakmp" but no output is showing up or giving any hint that it is trying to establish anything.

version 12.4

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.

It is normal DNS requests from site B to site A DNS. however, if the site to site tunnel is disconnected, site B not able to request site A DNS and do not jump to second DNS 202.66.192.68. I want siteB can use secondary DNS: 202.66.192.68 when tunnel is not connected.

I am using 5 Cisco 5505 ASA builed site to site VPN. site B,C,D,E all site to site VPN to site A with only IKEv2 IPSEC configurartion.
Reading from Site A ASDM. Monitoring VPN always can read all four site are connected. But, I found that Site D and E the login time during reset time to time with few hours.
1) I would like to know the login time during reset is normal or not?
2) any setup or configuration can fine tune the site to site VPN. Make VPN tunnel more stable?
3) any menthod can monitor site to site VPN is health or not?

I have ran into this problem in the past but clearly I usually change one of the remote host sub net ranges to something other than main site. Now I am in a situation that I just have to configure it this way. I just need some insight before implementation.
Inside (10.10.10.x/24) ASA5505 outside (97.65.x.x) ßà (97.664.x.x) outside ASA5505 (10.10.10.x/24)
Trying to create a site to site tunnel between each location with same sub net. I have found a lot of information about setting up this configuration with 8.3 and later but nothing for the image 8.4 and image 9.1(1) as everyone knows the ACL's and NAT statements are written differently now.

I've got a Cisco 5520, to which is a Cisco 5505 is connected via a Site to Site tunnel.The tunnel works just dandy, with traffic happily being passed to and from my Inside interface.
The issue comes with users connected to the 5505 access our DMZ, it simply refuses to work. I've read many posts about the changes made in 8.3 (which I'm running on the 5520) when it comes to NAT exemptions which I believe is the issue I'm having but I'm not able to implement any configuration to allow my site to site VPNs to connect to hosts within the DMZ.

On one of our branch locations ASA, I have a L2L VPN setup we are adding wireless to this remote location, and the AP's will talk back to the controller at HQ. The AP's are on the downstream L3 switch, and they have been placed on the mgmt network. It's definitely not ideal to have these AP's on the mgmt network, but for now that is how it is setup.
From HQ (163.122.x.x) I can ping and reach the ASA (10.200.2.1, and the downstream L3 switch 10.200.2.100, but when I ping one of the AP's, I get timeouts and and the following error on the ASA:%ASA-3-305005: No translation group found for icmp src outside:10.205.216.73 dst mgmt:10.200.2.152 (type 8, code 0)
It appears it's a NAT issue on the ASA, but I'm confused on what I need to change. Why can I ping the ASA and the switch from HQ, but not the AP's which reside on the same mgmt network? I don't really need it to NAT, just to pass the connections. I currently only have the following two NAT statements in the configure

I have a simple question, but want to make sure before I start. I have 3 5505 devices, 1 at corp, and 1 at two site locations. Is it possible to have multiple tunnels on the corp asa? one to site #1 and one to site #2?
My license is Base on all of the ASA's. I already have remote user VPN setup on the devices as well. Will that hurt or hinder anything to add the tunnels?

I'm having some troubles with SSLVPN connectivity. I've setup SSLVPN at one site and it works great with web access, file share, RDP plugin etc. at the local LAN on that site. But I also would like to reach another site (connected with an IPSEC tunnel). Is this possible? if it is, how do I do it?Both firewalls are ASA5505, one 8.31 and one 8.22 Just a note, it works to connect with IPSEC client and reach the remote site just fine.

I setup RA-VPN under local asa 5510 IP pool (192.168.127.0/24) and all was working fine. I got internet and local network access.
Then i have 5 site to site VPN working fine but when im traying to access to those L2L VPNs from the remote acces client im not able to do that. So after that i decided to obtain IP addresses from my DHCP server so i can obtain IPs from my local network (172.17.16.0/16) and then access normally to the VPN site to site. But the surprise was that the VPN cisco client is getting local IP address (172.17.16.222) perfectly but im not able to access even to my local network.
I have the same-security-traffic permit inter-interface same-security-traffic permit intra-interface enable.

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) :

I have a site-to-site VPN already established, everything is working as it should. I'm trying to block the remote network from accessing our network since we only need to access theirs. I'm sure this is something very easy to implement with an ACL but I'm not sure where this rule needs to go. The VPN is on ASA 5505.
