Cisco Firewall :: ASA 5505 / Site To Site VPN Using Public Addresses On Local Network

Jul 28, 2011

I have a request to establish a site to site VPN with a customer. While collecting the information I give them our local network subnet which is a private subnet (192.168.5.0). They asked me if I could give them a public address instead. They can not work with the 192.168.5 subnet. Is this possible?
 
My side of the VPN is an ASA 5505 running 8.2(2). The other side i believe is a Checkpoint.

Cisco VPN :: Remote Client Cannot Connect To Local Network Or Site To Site ASA 5510

Jul 21, 2011

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.

Cisco Firewall :: ASA 5505 Site To Site RTP Traffic Is Hitting Deny All Rule?

Aug 13, 2012

Got an ASA5505 connected to another endpoint running IPsec and being NAT'd at each end to a 10.0.0.0/24 network. I can pass other types of traffic through the ASA 5505 but not RTP traffic. The moment it is NAT'd and hits the firewall rules it gets denied by the default deny at the bottom of the list.

Currently the rules are as follows
 
 Incoming External
allow ip any any
allow tcp any any
allow udp any any
default deny

 [code].....
 
It wont allow us to setup a voip call...however when the same call manager sets up a voip call NOT using this ipsec tunnel it works just fine.

Cisco Firewall :: ASA 5505 - Local Host Names To DNS Server At Main Site

Mar 3, 2013

I ran into a very interesting problem that occurred today and I'm trying to figure out why it happened. If it was one ASA 5505 that just required the reboot, then I'd have just chalked it up to a glitch, but when we built a new AD/ DNS server on the main network at the main site and changed the 3 Remote site ASAs to point to the new DNS server in the DHCPD options, none of them could ping any local host names to the DNS server at the main site they were now pointing too, but external host names { URL} all translated and pinged fine.
 
From a laptop on one of the remote sites, we could ping the new AD/DNS server(192.168.0.3) and the old AD/DNS server(192.168.0.2) and everything else at the main site, and telnet to port 53 showed successful across the Easy VPN from the Remote site to the new server at the main site. When wire shark was added to the new DNS server at the main site, the DNS request and replies for {URL}, for example, came and worked fine, but any requests for local resources never made it to the server from the remote sites.
 
A reboot of one of the Remote Site ASA's corrected the issue. Then I rebooted the other two remote site ASAs, and now DNS was working fine for everybody. I had also tried clearing the ARP cache on the ASAs before resorting to rebooting them. I also tried rebooting the laptop thinking the local DNS cache needed cleared before resorting to rebooting the ASAs. I'm struggling to understand why external, public host names made it through and resolved from the remote sites to the new server at the main site, but anything local failed before even reaching the new server(The new DNS server could resolve requests made by computers at the main site, but the remote sites that traverse the Easy VPN from the ASAs failed).  The new AD/DNS server is the only server configured for DNS for all remote site computers.
 
Is any of this making sense? I'm wondering if clearing the x late or local host tables would have corrected it without having to reboot. I'm just trying to grasp the understanding here and figure out what happened.

Cisco Firewall :: ASA 5505 - Unable To Access Certain Ports Over Site To Site VPN

Jan 16, 2013

We have a client that has a Cisco 1801W Firewall that is setup as a site to site VPN terminating to a Cisco ASA 5505. The tunnel is up and established, I can ping from both sides of the tunnel.
 
The problem is the clients behind the Cisco ASA (192.168.2.x) cannot reach certain ports behind the Router (192.168.1.x). The main thing we're trying to do is browse via UNC path (ex: \192.168.1.120 from a 192.168.2.x machine).
 
I got 3389 working after I changed the - ip nat inside source static tcp 192.168.1.120 3389 y.y.x.x 3389 route-map DM_RMAP_1 extendable Modified the command to include the public IP instead of interface FastEthernet0
 
I believe it has something to do with the way NAT and route-maps are setup currently but I'm not familar enough with them to make the changes. I worked with Cisco to ensure the VPN tunnel was fine and it's something security related on the Router.
 
Here is the configuration (removed a few lines not necessary. y.y.x.x = WAN IP of Router x.x.y.y = WAN IP of ASA).
  
Building configuration...
  
Current configuration : 23648 bytes

Cisco VPN :: Site To Site VPN IPSEC Tunnel From ASA 5505 To Clavister Firewall

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.

I wanted to know the maximum VPN client sessions (using the Cisco VPN  client) and Site-to-Site VPN tunnels that I can connect to my ASA 5505  simultaneously.
 
In other words, if I have x VPN clients and y Site-to-Site  tunnels, at any time, does x + y have to be <= 10 (Total VPN Peers)?  If yes, can I upgrade to the security plus license to increase the Total VPN Peers to 25?

Cisco Firewall :: Site-to-Site VPN Between ASA 5510 And 5505 Configuration

Apr 18, 2013

I am not very experienced with Cisco networking.

Here is the situation.
 
Site A - headquarters 192.168.1.x
Site B - remote office 192.168.20.x
Site C - remote office 192.168.30.x
 
Site A - ASA 5510
Site B - ASA 5505
Site C - ASA 5505
 
Site-to-site VPN is established and works between A and B, A and C. Users would like to establish a tunnel between B and C to work on a common project and the data is on Site B.
 
I tried configuring the S2S VPN with pre-shared keys on both firewalls at sites B and C but in the end it is not established (I cannot ping either side). I used the Wizard interface multiple times and one time the CLI. I generally followed the settings chosen between the headquarter and the individual remote sites and tried to replicate them. Obviously I have made a mistake somewhere.
 
Could there be any limitation on the ASA 5505 in terms of licensing and the number of S2S tunnels?

We have got site to site VPN configured between local site with PIX515 6.3(5) and remote site with ASA 5505 7.2(4) . Because of very unreliable internet connection in remote site , we have added new ISP link  which we want to use as redundant link .i understand ASA 5505 can be configured with two ISP link with SLA monitor method for redundancy as per this document ,[URL]
 
my question is how do i set up this pix 515 to have redundant VPN tunnel with remote site (when primiary ISP link fails in remote site and  secondary ISP links takes over ) .  I was thinking of using   PIX 515 with 2 peers in same crypto map used for that sepcific site to site vpn tunnel,not sure that is the right way or not though.But how would i configure ASA 5505 to use backup interface(where secondar isp router conects ) to particitae in Site to site Tunnel .

Cisco Firewall :: ASA 5510 / 5505 - Site-to-site VPN One Way Access

We have a Cisco ASA 5510 at our main office that makes connection with a 5505 at our other office using site to site VPN. (works)
 
Now for the question,
 
we want to access our other office from the main office but we wont want them to have access to our servers etc. so basically we want to control them but they shouldn't have the rights to control us.

Is this possible with a site to site VPN? and how to do it.

Cisco Firewall :: ASA 5505 Site-to-Site With UC540 Routing?

Dec 4, 2012

We are setting up a new phone system using the UC540 with a VPN connection between 2 buildings using 2 Cisco ASA 5505's at either end.The problem I am having is getting the phones at the remote site to connect to the UC540 at the main site.
 
Phones/Computers (10.0.1.0/24) -- ASA -------------VPN Tunnel------------- ASA -- UC540 -----------Data Vlan1 (10.0.0.0/24)
|------Voice Vlan100 (10.1.1.0/24)
 
What i am told by UC500 support is that the phones at the remote site will connect if they have connectivity to the TFTP subnet on the UC540, which is 10.1.10.0/30 I added the static route on the ASA and I can ping the 10.1.10.1 TFTP server on the UC540 from the ASA, but not for any other device on the 10.0.0.0/24 network, such as the DC.  I added the static route there and was able to ping, so something in the ASA seems to be preventing it. 
 
I also can't seem to get the ASA at the remote site to ping 10.1.10.1.  I've tried adding the static route there in hopes it would forward it through the VPN tunnel.

Cisco Firewall :: Site To Site VPN Configured On ASA 5505

Dec 2, 2012

I have a site to site VPN configured on a asa5505. The tunnel is up and the interesting traffic is successfully being encrypted. The issue is that when inbound traffic originating from a subnet outside of the encrypted range destin to the subnet within the encrypted range, the return traffic is sent into the tunnel and obviously fails.When traffic from 1.1.1.0/24 to 10.2.2.0/24 traverse the firewall the return traffic goes into the tunnel but it doesn't have the correct match parameters?Am I missing something?  I'm expecting that only traffic matching the crypto map will use the tunnel and all other traffic will utilize the default route.

Cisco VPN :: ASA 5505 - Users Aren't Able To Reach Remote Network Through Site-to-site Tunnel

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

Cisco Routers :: SRP527W Site-to-Site VPN Not Hiding Internal Addresses?

Jun 11, 2013

We recently purchased an SRP527W router because of its capability to configure site-site VPN tunnels. The configuration of IKE and IPSEC is working and the tunnel comes up but the problem is that the router is passing our internal IP addresses through the tunnel. The remote end we are connecting to requires us to hide all traffic behind one IP address which would ideally be our external static IP address from our ISP.

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 (site1.dyndns.org and site2.dyndns.org) 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 (site.dyndsn.org and site2.dyndns.org) of each site on both routers, with corresponding remote subnets

Cisco VPN :: 5505 Connection To Mapped File Shared Dropping On A Site-to-Site VPN

Nov 27, 2011

We've just deployed a site-to-site VPN using a 5505 ASA on the client's site and a checkpoint Nokia FW on our site. Everything seems to be fine except that the user's connections to their file shares seem to be intermittently dropping. One minute the connection to the shares is there, next thing it's lost. There is no logic to it because no two users are experiencing issues at the same time, as a matter of fact even on the same PC where a user has access to 3 shares on 3 different servers, one could be showing as connected whereas the other two be dropping. [code]
 
As you can see the Duplex and Speed are set to auto, I've rectified this since then and I'm keeping a close eye on the output errors, and collisions. However, I'm afraid that this did not rectify the issue and the users are still experiencing intermittent connection dropping to their file shares over the VPN!

Cisco WAN :: 5505 Correct Site-to-site / SSLVPN Security Device

Dec 12, 2012

I have tried Cisco presales but got bounced - go Cisco !So, i have a small customer who requires a single device which will provide .....
 
1/ Leased Line connection @ 10mb
2/ ADSL failover onbox (so configurable from CLI, unlike the 860’s which I see only have one ‘active’ wan port)
3/ IOS based
4/ integrated 4 ports (min) switch
5/ site to site VPN
6/ up to 10 x SSLVPN remote users
 
I did pitch in with ASA5505 with external ADSL router but he is “space-constrained”.It worries me when Cisco doc's say only one WAN port is 'active' - since it doesn't say the second port automatically comes up if the first goes down so I can't take a gamble on that being the case.
