Cisco VPN :: ASA 5520 How To Assure About Having IKEv2 Tunnel Instead Of SSL
Mar 18, 2012I've ASA 5520 with 8.4(3) running.I want to set up VPN remote access using following document url...I managed to get a connection running, but when I check the connection on the ASA, it shows as a SSL-tunnel, not an IKEv2 tunnel.How can I assure I have an IKEv2 tunnel instead of a SSL tunnel ?Can I do with annyconnect same kind of connections I used to do with the Cisco VPN client for IPSEC?

Nov 1, 2012We just migrated from a single 5510 to a dual (failover) 5520, It seems that everything is working except the remote VPN. We can establish a tunnel and authenticate as local users, (going to LDAP when all is working) but no traffic is passing. I know I am overlooking something but cant see it. [code]

Oct 2, 2012I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.

Cisco VPN :: 5520 - Tunnel Up But Not Passing Traffic
Jan 15, 2012I have a site to site tunnel between two 5520 ASAs. Tunnel is up but when I try to talk to the other side, the implicit deny on the inside interface of the local ASA blocks the traffic. When I ping, the tunnel comes up but in the logs it says it is blocking icmp from inside to outside. I have tried the sys opt connection permit-vpn but it is not working. The traffic is from 5 specific machines within the local sub net that I put in a network object group called Celerra_Replication.
I want to them to be able to talk to 5 machines on the far end of the tunnel in a seperate sub net. They are in a net wrok object group called GP_Celerra_Replication The ACLs I created for this appear to be created correctly allowing IP from Celerra_replication to GP_Celerra_Replication and the opposite on the other side.
Cisco WAN :: 871 / 5520 - L2L IPSec Tunnel Between Two Routers
Apr 4, 2011Here is the situation: A CISCO871 router is configured to establish an IP SEC tunnel with a CISCO ASA5520. The configuration is OK about that. I wish to configure the same CISCO871 in order to establish a LAN-to-LAN IP sec Tunnel with another CISCO871 at the same time in order to reach private network. So, I have followed the Cisco procedure Document ID: 71462 "LAN-to-LAN IP sec Tunnel Between Two Routers Configuration Example"; it works, I can reach the peer private network BUT ONLY when the IP SEC tunnel with ASA is not established.
It seems to be a routing problem...I don't find how to configure to make both tunnels up and functional at the same time.

Aug 23, 2011We have a 100 Mbps WAN circuit, we have configured an IPsec tunnel between ASA 5520 and Cisco 3845 Router for our DR site replication via Veeam Backup and Replication, it was working fine before, when we established the 3DES tunnel the traffic for certain subnets is dropped after an hour and it stops the replication, although tunnel remains up and we can access the other subnets, as soon as we clear the crypto SA and ISAKMP sessions on the firewall the traffic starts flowing again and then after an hour the traffic is dropped again.So far the testing and differnet configurations we tried are as under.
Tried with a different MTU size both on firewall and ESXi servers but nothing happened.Their is no QOS configuration.Checked the utilization on both ends its Noram although their are subsequent 100% spikes on Cisco 3845 but on average it remians at 30-40%.
Cisco VPN :: ASA 5520 8.4(3) Tunnel Default Gateway And Various Subnets
Apr 9, 2012I am struggling on a problem for over 2 weeks despite of various researches.
We have a Cisco router, then an ASA 5520 8.4(3).
The private interface of the ASA is connected to a switch, and so on connected to one interface of the router.
The private interface is as following : 129.88.63.253 255.255.248.0 (/21) =>
It is in the 129.88.56.0/21 subnet
Here is the part of the router config we are interested in :
!
interface Vlan32
ip address 129.88.63.254 255.255.248.0 (this is the tunnel default gateway configured on the ASA - 129.88.56.0/21 subnet)
ip address 129.88.71.254 255.255.255.0 secondary
ip address 129.88.75.254 255.255.252.0 secondary
ip access-group CVPN-depuis-129.88.56 in
ip access-group CVPN-vers-129.88.56 out
ip verify unicast source reachable-via rx allow-default
no ip redirects
mls rp ip
!
On the ASA, there is currently one default route for the tunneled traffic :
route Private 0.0.0.0 0.0.0.0 129.88.63.254 tunneled
As you can see, it's on the same subnet as the primary IP address of interface Vlan32 on the router.
The scenario is as following :
- we can connect to the VPN with the appropriate alias (LDAP connection), then we get an IP address in the defined range (it's a local ASA pool)
- the pool is : 129.88.71.0/24
- but, once we are connected, we can't do anything, because it seems like we don't have any network access
Cisco VPN :: VPN Tunnel Between ASA 5520 And Juniper Tears Down Intermittently
Feb 13, 2013VPN tunnel between ASA 5520 ver 8.0(4) and a remote Juniper firewall keep tearing down during Phase 1 rekeying. After the rekeying process fails, manually pinging one of the remote hosts that are proteced behind the Juniper firewall,initates the tunnel renegoation and rebuilds the tunnel successfully.
When the tunnel is down, sh crypto isakmp sa shows no active SA for the remote peer. That indicates the PHASE 1 negotation had indeed failed.When the tunnel is working, sh crypto isakmp sa indicates an IKE role of Responder - always.Clearly that also means Phase 1 negotation works only one way, i.e. negotation initated by the remote Juniper unit only.
Interestingly, the Syslog server logged the following SNMP trap messages at the time rekeying Phase1.Note, Line#2 and #7 and wrapped to the next line for easy of reading.
Line#1: IP = Remote-Peer-IP-#, Starting phase 1 rekey
Line#2: IP = Remote-Peer-IP-#, IKE Initiator: Rekeying Phase 1, Intf outside,
IKE Peer Remote-Peer-IP-# local Proxy Address N/A, remote Proxy Address N/A, Crypto map (N/A)
Line#3: IP = Remote-Peer-IP-#, constructing ISAKMP SA payload
[code]...
As I understand from the above syslog trap, the Responder ( the ASA unit this time) started Phase 1 rekey (Line #1). It prepare a message to be sent to IKE Initiator, that it is about to start rekeying Phase 1 (Line #2). Down on the next line, it indicated that the local Proxy, remote Proxy and Crypto map as N/A ( not avaiable).Why would the ASA unit send N/A message as shown in Line#2, is that normal?

View 7 Replies View RelatedCisco Firewall :: 5520 - SSH Socks Tunnel Set Up On Server
Jul 18, 2012I have the following setup
|| Socks Server || >> Switch1 >> ||Cisco 5520 ASA || -->> | Switch 2| -->> Clients
I have a SSH SOCKS tunnel set up on the socks server which is a Linux box. When I connect my machine to the switch 2, I am NOT able to receive and mail by setting up a mail client and it seems SOCKS traffic does not reach the socks server. I can however run a telnet command on port 1080 (socks port) which connects which shows that the port was going through and open. However there was no SOCKS traffic. When I connected the machine to Switch 1, SOCKS traffic worked as expected and I was able to receive mail.
This suggests to me that the ASA has some inherent rule that does not allow SOCKS traffic. IS this true and if so how can I bypass this?

Apr 11, 2013I'm trying to achieve a site-to-site ipsec tunnel to a Cisco ASA 5520. Most examples feature the ASA with a public interface that terminates the tuennel and a private network on another interface that the tunnel interacts with. Where my scenario differs is that the interface that accepts the tunnel is part of a public /29 network where I want the remaining hosts on that subnet to be able to route thrugh to the other end of the tunnel. My tunnel gets established, but any attempts to route via the IP assigned to that one interface result in the ASA rejecting traffic. If so, what configuration options should I consider?

Cisco VPN :: Establish Site To Site IPSec Tunnel Between ASA 5520 And 3030?
Feb 17, 2013We have configured a site to site tunnel from our ASA to another organizations Cisco 3030. It appears to have just one way initiation. We can do a ping to a device on the remote site and it will ping just fine. however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional. And once established, traffic can flow bidirectional.
