Cisco VPN :: ASA5505 Can Reach All Remote Networks Throw Tunnels
Jan 31, 2011
I have a friend that have in his company an ASA5505 at central point and about 5 remote sites connected via Vpn site-to-site.All tunnels are up and reach the central network.The only traffic that pass throw the tunnel is the traffic with the ASA local network destination.
My friend asked me what it needs to reach from one Vpn remote site to another Vpn remote site, passing throw the ASA5505 central site.The ASA5505 can reach all remote networks throw the tunnels.
What it needs for the ASA to route traffic between the VPN´s tunnels?Does it need static routes on the remote sites to advertise the other remote sites ?

I have a (central) ASA5510 acting as a EasyVPN server and a number of (remote) ASA5505 as EasyVPN client. All the communication works fine between the different networks. The issu is the ASA itself. The remote ASA can ping the central ASA on it's internal IP-adress, but it can't ping any other resoruces at the central network. If I ping the DC at the central network from the remote ASA I get a deny in the central ASA with source address as the public IP-adress of the remote ASA and destination of the internal address of the DC. If I from the remote ASA do "ping inside ip-of-central-dc" it work's like a charm, but "ping ip-of-central-dc" dosen't work.

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 set up a full mesh LAN-to-LAN VPN for a client with 4 sites. Each site has an ASA 5505 running 8.2(5). Site-to-site VoIP traffic runs in the VPN tunnels, as well as traffic to/from a file-server located at the main site. There are two back-up servers, one at the main site and one at a remote site. The main site has 2 bonded T1s and the other three sites have a single T1. How should I go about setting up my QoS?
My top requirement is that VoIP traffic will never be pushed out of the way for data traffic. My secondary consideration is to give more preference to file-server traffic than to web traffic and to make back-up traffic the least important. I'm currently researching to see if the VoIP provider is DSCP marking EF on the VoIP traffic, but I am going to assume they are for now. I know the IP of the file-server and back-up servers.

I have 3 tunnels established (full mesh) with 3 CISCO ASA (all security+), through Internet : - Site A : ASA5510 - Site B&C : ASA5505, There is no main site or client site, each site has more than one network behind it. So I'd like to setup OSPF between all the ASA for them to exchange their route within the tunnel. I thought this was automatic when establishing the tunnel, but it isn't.

I have ASA 5510 and configured client VPN or Annyconnect VPN, when I connect to the ASA remotely using anyconnect I am able to get IP address as configued, from Internal network I can ping and RDP that anyconnect VPN desktop, but the problem is from the remote anyconnect VPN client I am unable to access internal network, when I use ASA packet tracer and check traffic from internal to anyconnect pool of addresses it gives result ok, but when i use packet tracer to check traffic on outside interface from anyconnect address pool to internal subnet it always gives the packet is dropped at WebVPN - SVC, and I can find any where related configuration for that.

-cisco 2651xm router
-cisco 1760 router
I have a cisco 2651xm router here at home, and at another remote location I have a cisco 1760 router, both are connected to the internet via adsl (WIC1-ADSL card).The problem is that from home I can't connect to the snmp-service on the 1760 router. I'm using a PC that's on the LAN of the 2651XM router, the blockage is in the 2651XM router, because if I swap it for a cheap plastic domestic router I can get snmp data from the 1760 router, and this is without any port forwarding in the domestic router. What config do I need on the 2651XM router so it will pass this traffic?

We are facing strange issue in our network. We have a remote branch which is connected to main branch using Leased Line. Remote branch is having Cisco 1700 Router. Every day in the morning time the remote router is unreachable. We are not able to reach (ping/telnet) the remote Router but able to reach L3 switch/ LAN behind this router. The users from remote branch is also not able to reach the local router but they are able to ping the Main branch.Users in the remote branch are not able to access any resources in the main branch during the issue.
During the issue, we have checked the remote branch router and found the CPU utilization of the Cisco 1700 router is very high (99%). If we run "Show process CPU" command (please find the attachment) specially IP input process is very high (97%).

I have one ASA with two tunnels. Each going to a different 3rd party Checkpoint firewall (site A, site B) Each site has two servers (A1, A2, B1, B2)I can only connect to A1 and B1. any connection to A2 and B2 fails. I have defined B2 and A2 in the crypto map to be protected.If I only have B2 or A2 in the crypto map ACL then the tunnel fails. Phase 1 does not come up. Its as if the ASA is ignoring the entries for B2 and A2.ASA running 8.4(2).I have also trashed the VPN and built via the wizard, same result.

I have 25 of these routers installed behind various providers and transport (DSL, Cable, UVerse). At sites where I have static IP, I can't reach any service inside, and in fact can't even reach the router for Remote Management. At all times the users indoes can do whtever they like, the have Internet access.
At sites where we draw a dynamic IP or use PPPoE, I can reach services and manage the router until a known issue stops the inbound traffic.

I have and office that the cable modem tends to go down on the weekend. Can i setup my asa to support a second provider so that if the one connection is slow for some reason, my users could connect to the second provider instead? they would both be used at the same time most the time.

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

I have been searching for days trying to find out what could be wrong with the configuration of an ASA5505 running Firmware version 7.2(2). I am trying to set up a hairpin connection between my laptop on the VPN tunnel (192.168.25.12) to access the server across the L2L VPN (192.168.1.10) on the diagram below.
The remote VPN function is working, as I can RDP to the 192.168.25.10 server from my laptop, and the L2L VPN is working since I can RDP from server 192.168.25.10 to server 192.168.1.10. I am trying specifically to run RDP from my laptop without having to log into the .25 network.
I have tried multiple changes to my NAT tables and my ACL configurations to no avail.[code]

We currently have a few 5505s installed at client sites which are connected via s2s ipsec VPN to our datacenter's 5510. We are using Nagios to monitor the local data center and remote client infrastructure (over the VPNs) which has been working well.
We would like to also monitor the remote 5505s using SNMP over the s2s tunnels but it doesn't seem to be working, the connection is timing out. We've configured the remote 5505s with the same snmp statement we used on the 5510 (snmp-server host inside <remote datacenter IP> poll community ***** version 2c) yet the Nagios SNMP check cannot connect to the remote 5505s. We've also tried the command using 'outside' without any luck, not sure how to get SNMP to route over the VPN.

I have a ASA 5505.|I configured it for remote access VPN from cisco VPN client.the ASA receives a public ip address on outside interface via PPPoE.I can connect to public ip of outside interface and address 10.1.1.2 is assigned to my Cisco vpn client.the problem is that I Cannot ping or reach ASA internal IP address 172.16.29.1 in any way when I am in VPN from outside,while I Can ping other hosts on 172.16.29.0/24 when connected in VPN.this is a problem brcause when I am connected in VPN to ASA I Cannot configure it..Then I Wanted to ask if it is possible a configuration which gives addresses from network 172.16.29.0/24 (the same as inside network) to VPN clients instead of another network (10.1.1.0/24) [code]

I have configured ASA 5505 for remote access VPN to allow remote user to connect to the officce LAN from remote locations. VPN working fine, users can access offce LAN and sahred resource etc but once they connected to VPN, they can not browse the internet ? Internet browsing stop working as soon as their VPN client connnect with ASA 5505 t, once they are disconnected from the VPN , again they can browse the internet.
Does ASA 5505 blocks the internet browsing for VPN users ? Is there anything else I need to congfure to make sure VPN users can browse internet? Do I need to configure Split Tunnleing , NATing or routing for the VPN users?

I am trying to configure RemoteDesktop on a home lab ASA5505 with IOS 8.4.1 and no matter what I tried, I am unable to remote into a local server behind the firewall. I've searched online and found several threads with solutions online including here at Cisco Support Community forum and have tried them all, but have no success. I'm sure it may be something very simple that I've missed.

I have setup a Remote access VPN on my ASA5505 firewall through the ASDM wizard.I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows incoming Rx packets. However, Tx packets remain 0, so no traffic is going out. My ASA5505 is configured as router on a stick with 25 different VLAN's. I want to restrict traffic to one specific VLAN using a crypto map.When I issue a ping -t command on my connected Windows box, the firewall log shows me the following message:
"IKE Initiator unable to find policy: Intf outside, Src: 10.7.11.18, Dst: 172.16.1.1."
"This message indicates that the IPSec fast path processed a packet that triggered IKE, but IKE's policy lookup failed. This error could be timing related. The ACLs that triggered IKE might have been deleted before IKE processed the initiation request. This problem will most likely correct itself." [code] I have really no idea what's going on. I have setup a Remote access VPN countless times but this time it shows me the error as described above.

I have several locations with time clocks (a Kronos application) on a small home network with outgoing traffic wide open.I have a server in my office behind an ASA5505 router/firewall, also with outging traffic wide open. I have tried taking the device off of the remote network and giving the it a public, static ip address so it is actually on the internet, yet the server cannot see the device, but it can ping it. I was advised to put the device on the remote private network and set up a virtual server using port 8080 at the remote location. The server is still unable to see the device. I also set up a virtual server for VNC. When I am on my server on my work network behind the ASA5505, I can start my VNC viewer and attach to the device at the remote site using the IP of the router (apparently the device has a build in VNC server).
I have also tried to NAT my server to a public IP, I have set up incoming and outgoing rules on the firewalls at both ends.this should be a fairly straight forward connection.

A customer has a ASA 5505 with a remote access vpn. They are moving their internal network to a new scheme and would like users who come in on the vpn to access both the exisiting and new networks. Currently the can only access the exisiting. WHen users connect to the remote access vpn, the asa gives them an address of 192.168.199.x. The current internal network is 200.190.1.x and they would like to reach their new network of 10.120.110.x.
Below is the config:

I have an ASA 5520 8.2(3) and allowing my remote client-to-site-vpn clients to access resources directly connected to my ASA on separate lower security interfaces (not the outside) besides just clients on my internal networks. Someone mentioned to me configuring 'VPN on a stick' however from what I've read this seems to be only applicable when it comes to split-tunneling back out the outside interface (could be off on that). Is this possible on other lower security interfaces as well, and if so what would a mock config that accomplishes that look like (acl's, nat, etc)? Also, if I want internal users to be able to connect to these remote clients once they are active, are there any nat statements necessary (such as nonatting them) or are the vpn clients just seen as internal clients from the rest of the internal network's standpoint by default?

We have two sites connect with an IPSec L2L VPN.
-Site A: 192.168.13.0/24
-Site B: 192.168.2.0/24
On both sites we have a ASA5505(Base license) to terminate the tunnel.On Site B we also got a remote access vpn to which we can connect using the vpn client.The lan2lan tunnel works fine and so the remote access vpn.Now i want to connect to Site A using my vpn client connected to Site B. [code] There are no vpn-filters or other special policys in place..If tried to ping from my vpn client to Site A while i was debugging ipsec 255 on site B: the asa matched the l2l-tunnel for traffic sourced from 192.168.25.x to 192.168.13.x but when im doing a show crypto ipsec sa detail there are no packets getting encrypted..so of course no packets reaching my asa on site a.

I have noticed a problem recently that our Remote Access VPN will randomly stop working. I will be able to connect and enter my Username+Password and it says Connected, but I cannot ping Remote Resources. If I check VPN Client Statistics, it shows Many Packets Sent/Encrypted, but None Received. It seems this problem affects all devices at once, but leaves the L2L tunnels intact.
It seems to randomly start working for a while, and everything seems fine until it stops working again. I verified that it is not a firewall problem, and it occurs on multiple ISPs and computers.
We also have 2 Static L2L Tunnels, and 1 Dynamic L2L Tunnel all of which operate flawlessly. All sites/remote users use split tunneling.
Below is the config, I just added the keepalives on the RA Tunnel to see if it would work, I haven't noticed any difference yet.

inside network----ASA5505========internet===========Remote VPN client.
The ASA has one public IP on its outside interface and using PAT to the internet. It only has two interfaces, inside and outside using vlan. I created a IPSec VPN through CLI. My goal is for the remote client to browse the Internet throught tunnel.
Q1: Is it possible?
Q2: The remote side gets connected and has IP from the pool, with is part of inside network. But it cannot ping anything, including the gateway, which is the inside interface. I debug it, it shows the ASA receives the ping packages, but it doesnt send anything back to the client.
