Security / Firewalls :: Cisco - Unable To Configure Site-to-site Vpn

Sep 14, 2012

I am configuring Site-to-Site VPN with another company. I already make a couple of tunnels but with this one I have a problem. They I already using on their side my local network 192.168.10.0/24 (server is 192.168.10.10) so we need to use imaginary network 172.16.0.5 as server address. Now I need to do NAT 172.16.0.5 to 192.168.10.10 but I am not so good in that.

Cisco VPN :: 5505 - Two Site To Site To Same ASA Firewalls

Nov 6, 2012

I have a scenario whereby I need to add a second VPN tunnel to a Cisco ASA, however its peer address will be on the outside2 interface on the remote firewall. 
 
we have ASA1-HQ 5505
 
Inside address - 172.16.20.0
 
Outside1 - 1.1.1.1
Outside 2 - 2.2.2.1
 
ASA2-DC 5510
 
Inside Address- 172.16.30.0
Outside1 - 3.3.3.1
Outside2 - 4.4.4.1
 
There is currently a VPN tunnel between 1.1.1.1 and 3.3.3.1. I need to add a 2nd VPN tunnel utilising outside2 addresses 2.2.2.1 & 4.4.4.1 respectively.
 
I have labbed this out, however i cannot get traffic going down to the 2nd VPN tunnel. I have created the following routes on each firewall
 
ASA1-HQ
 
Outside1 0.0.0.0 0.0.0.0 1.1.1.2 (metric 1) (Next hop for outside1 interface)
 
Outside2 4.4.4.1 255.255.255.255 2.2.2.2 (metric 1) Peer address of 2nd vpn tunnel)
 
ASA2-DC
 
Outside1 0.0.0.0 0.0.0.0 3.3.3.2 (metric 1) (Next hop for outside1 interface)
 
Outside2 2.2.2.1 255.255.255.255 4.4.4.2 (metric 1) Peer address of 2nd vpn tunnel)
  
I have tried adjusting the Crypto map Priority values however this has made no difference. One theory I have is the local addresses potentially would need to be on a separate network in order for traffic to traverse the 2nd VPN tunnel.
 
the crypto maps i have created are:
 
ASA1-HQ
 
Outside1 (Priority10)  S 172.16.20.0 /24 D 172.16.30.0/24 Protect ESP-3DES-SHA Peer 3.3.3.1 (Nat T Enabled)
Outside2 (Priority 1)  S 172.16.20.50 /32 D 172.16.30.50/32 Protect ESP-3DES-SHA Peer 4.4.4.1 (Nat T Enabled)
 
ASA2-DC
 
Outside1 (Priority10) S 172.16.30.0 /24 D 172.16.20.0/24 Protect ESP-3DES-SHA Peer 1.1.1.1 (Nat T Enabled)
Outside2 (Priority1)  S 172.16.30.50 /32 D 172.16.20.50/32 Protect ESP-3DES-SHA Peer 2.2.2.1 (Nat T Enabled)
 
Is what I am attempting feasible?

Cisco Security :: 7206VXR And Watchguard / Establish A Site-to-site VPN Connection?

Nov 13, 2011

our customer unfortunately uses a Watchguard.Finally we could establish a site-to-site vpn connection.To test if the connection re-establish again, we cleared our vpn session by "clear crypto isakmp <session id>" and after that "clear crypto sa <ip address of the peer>"After that, the session  is down on our site, but the watchguard keeps the Phase I still up, either the deleting messages from our cisco are visible in the watchguard log files.Watchguard helpdesk told us, that the messages are only seen as a deletion message for Phase II, therefore Watchguard keeps Phase I up and running.Here you could see the cisco 7206 log messages aftre the clear commands:
 
: Nov 10 13:22:06.508 MEZ: IPSEC(delete_sa): deleting SA,
2011-11-10 13:22:06 Local7.Debug   649460013:  :   (sa) sa_dest= <local peer>, sa_proto= 50,
2011-11-10 13:22:06 Local7.Debug   649460014:  :     sa_spi= 0xEB0AE65A(3943360090),
2011-11-10 13:22:06 Local7.Debug   649460015:  :     sa_trans= esp-aes 192 esp-sha-hmac , sa_conn_id= 669,
2011-11-10 13:22:06 Local7.Debug   649460016:  :   (identity) local= <peer>, remote= <peer>

[code]....

In my opinion, it looks ok and we do not have problems with other VPN devices with this kind of tests.what could be done that the watchguard deletes Phase I, too? Or that an explicit Phase I deletion message is created and sent by our cisco 7206?

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.

Cisco AAA/Identity/Nac :: Configure Radius Authentication Across Site-to-site VPN For ASA 5510-01 For Remote Access?

Jun 28, 2012

I am attempting to configure Radius authentication accross a site-to-site VPN for my ASA 5510-01 for remote access.
 
 ASA5510-1 currently has a live site to site to ASA5510-2.
 
ASA 5510-1 - 10.192.0.253
 
ASA 5510-2 - 172.16.102.1
 
DC - 172.16.102.10
 
ASA5510-01 can ping the DC and vica versa but is unable to authticate when i perform a test. ASA5510-01 can authenticate to a DC on it;s own LAN but not on the remote LAN that DC sits on.
 
I have double checked the 'Server Secret Key' and ports as well as various users which all work locallly. ASA5510-02 authenticates to DC with no problems.

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

Aug 22, 2011

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 (192.168.89.1) 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 192.168.89.1, 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 :: 851 - Configure QOS For Voice Traffic Over Site-to-site VPN Tunnel

Jun 16, 2011

I want to configure QoS for voice traffic over a site-to-site VPN tunnel. I have a Cisco 851 router on the branch end and a Cisco 1800 router at the HQ. The setup is an Avaya Gateway located at the HQ and the idea is that the phones at the branch office are connected over the VPN tunnel to the gateway at the HQ.

I have a 1MB internet link at the HQ from a service provider and 256kbps internet link (from a different service provider) at the branch office. The branch office has just 3 users.

Cisco Security :: ASA5505 Site-to-Site VPN And SLA Monitor

May 13, 2012

I have a couple of ASAs 5505 (HQ & Branch) running version 8.2(4).  They are configured with a Site-to-Site VPN over a single WAN link: [code]

I want to enable sla monitor on one of the devices in order to know the real status of my unique link because the interfaces sometimes don't go down, so I don't have any real statistic of failures. 
 
All the information is related to dual ISP links failover.  Is there any extra-consideration for my single link scenario?I already have a static route route outside 0.0.0.0 0.0.0.0 192.168.0.1 1 so I think I have to overwrite it with something like this route outside 0.0.0.0 0.0.0.0 192.168.0.1 1 track 1. Is this correct?If so, when I overwrite it, will the S2S VPN go down and will it go up automatically?

Cisco WAN :: 2911 - Site-to-site IPsec Vpn / Unable To Ping Remote Network

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).
