My question is very simple is there any way or feature that could allow us to have a backup VPN tunnel on at the secondary ISP at the asa 5520? Lets assume if the primary isp goes down is there any way for the VPN tunnel come online at the backup isp ? [code]

View 33 Replies View RelatedI have two routers on my local network:
1. ADSL Wi-Fi router provided by my ISP. This is the primary router for my network which is connected to the internet. Router IP: 192.168.1.1 (DHCP enabled)
2. TP-Link wireless router which is connected to the primary router through its LAN port (not WAN) with its DHCP turned off. So I'm using this router ONLY to extend the network to another area. This is a 3G enabled router. Router IP: 192.168.1.2
There are two different wireless SSIDs but basically only ONE network (all the PCs connected through any of the two routers are on the same subnet and have same IP range i.e. 192.168.1.x). I want to use the 3G internet connection through the secondary router when the ADSL connection is down. Whenever the ADSL connection is down, I would just connect the 3G-USB to the secondary router, all the computers on the network should connect to the internet while skipping their route through the primary router WITHOUT CHANGING ANY SETTINGS. Is it possible? Do I need to modify the routing tables? Or is it possible by configuring the DHCP server to assign the primary DNS address as 192.168.1.1 and secondary DNS address as 192.168.1.2?

I already configured the said instructions but when I send a test email it says it cannot contact the email server. Below is the error that I am getting from our ASA. I am new to firewall.

We have an ASA 5520 in production with a brand new internet feed we've just finished installing. We connect to our corporate office via a VPLS. In our corporate office we have a Cisco 1841 (I think that was the year it's made! ) with an ADSL feed with a static IP address plugged in directly.
We have a user VPN that we integrate with our user directory on the router, which connects via the ADSL. The users get an IP addres at the tail end of the 172.31.14.0/24 range, which is the same as one of our corporate subnets (we just reserver a few address, we don't have many VPN users).
Both the ASA and the router connect to each other (via the VPLS) on the internal subnet 10.255.255.0/24.
-The ASA is 10.255.255.1
-The router is 10.255.255.100
Currently the default route for the corporate office goes out the Dialer interface for the ADSL, which means that's where our internet goes out there (all proxying aside, we'll leave that out of this one). ip route 0.0.0.0 0.0.0.0 Dialer1
We'd like to change that default route to go via the VPLS to the ASA, and then out to the internet using the new feed. All the ACLs and rules are in place at both ends for this to work. If I change the default route on the router to: ip route 0.0.0.0 0.0.0.0 10.255.255.1Then it works as expected.
The problem is that then the user VPN breaks. I had hoped I wouldn't have to do any configuration on this but it looks to be so. I'm guessing that the VPN packets are coming in via the ADSL and back out via the new internet. It would be simple if the remote client had a static IP address as I could put in a static route for each user, but it's always going to be dynamic.
What do I need to put in place to get this working? I thought maybe I could leave the default route via the ADSL and put in a next hop rule to go via the VPLS for the specific subnets that need the new internet, i.e. have a subnet specific default gateway, is this possible? (I gave it a go but it didn't seem to work, I think I didn't implement it properly though as it still went via the ADSL, maybe because there is a nat route-map as well?).
I would like to knwo if i have dual ISP feature with my ASA 5520 licence? With ASA 5505 i can see Dual ISP feature but with ASA 5520 it's not!

In that setup now I have to add one more subnet and as the first subnet is been defined in ASA indside interface, I have to assign secondary Ip to the inside interface so that new subnet users can easily reach here and go outside.
View 1 Replies View RelatedI have a pair of ASA5520s in active/active failover - this works fine. Both primary and secondary ASAs are running 8.2(2) code.I have a 30-day temp 50 seat SSL license that I applied to the primary. I then started having problems with L2L tunnels.
I noted that if the 'show crypto isakmp sa' state for an L2L was MM_STANDBY, then the remote protected net could not reach my side. However, I could ping across to the other side at which time the state changed to MM_ACTIVE as I would expect and the remote could then reach my side.
I believe this results from the differences between the two licenses. When I applied the 50 seat SSL lic. it disabled failover, but I was willing to risk that for a few days to do show my customer the benifits of SSL connectivity. Note license differences. Is this causing the MM_STANDBY IKE issue and if so can I overcome it and use the 50 SSL VPN Peers lic.

I have a working DMVPN solution. I am trying to stand up a secondary DMVPN hub at our disaster recovery site. We are trying to deply to a Dual HUB SIngle DMVPN solution. The HUB2 DMVPN router has an INSIDE trusted interface and has an OUTSIDE UNTRUSTED interface.
The inside is 10.248.11.X...the Untrust/public is 192.168.93.11 which is connected to our DMZ 3 on the ASA 5520.....then I am trying to NAT the 192.168.93.11 to an outside public IP 199.248.30.X....just not working...have had 2 tickets open with Cisco this week and they still are unable to resolve. I am sure it is the ASA5520 is not configured correctly.
i just received a RMA for failed ASA 5520 that was acting as secondary unit in multicontext configuration. What would be correct procedure to install it back in production? Do i need to restore backed up config of the fallen unit or is it just enough to enable multimode and connect to existing (primary) unit? Any good link for documentation that deal with this issues.

I have a client that has an ASA 5520 that has two internet connections, FIOS and Comcast. The ASA is configured to failover from the FIOS to the Comcast if the FIOS fails. This works perfectly fine. However, I was wondering if VPN and other inbound traffic will come into the secondary connection when it is active. I think VPN will work inbound when the FIOS connection fails, but I am not sure about the other inbound connections.

View 12 Replies View RelatedI 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.

I 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.
Here 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.
I have a two ASA 5520's and I want to be able to see or monitor the traffic between each tunnel. I am using external addresses but for the sake of this question I will use the following: 1.1.1.1 to 2.2.2.2 . How can I montior the traffic?

I 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
VPN 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?
I am getting the below messages in my cisco asa 5520, during this time tunnel is down. just what to check whether the problem is at remote FW or with asa

|| 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?
We have a Cisco ASA 5520 supporting multiple VPNs - both remote-access and Lan-to-Lan. We would like to monitor the bandwidth utilization of the IPSec Lan-to-Lan tunnels.
