Cisco Firewall :: ASA 5510 - Terminate Second ISP Link On One Of DMZ Interface?

Jun 20, 2011

On our ASA 5510 we already have one ISP link terminated on outside interface. There is correspoinding nat and global configured for outbound access to internet.
 
Now we need to terminate second ISP link on one of the DMZ interface to have redundancy for the primary ISP. 
 
When primary ISP link or router is down we need to send all the traffic to secondary ISP router.  How do we configure NAT and global for this condition that only when primary is down then only this NAT -Global should be used.  Do we have anything like object tracking associated with the NAT-global.
 
So that as long as Primary  RTR - object is up ASA will use the first NAT-Global pair. When primary ISP is down RTR-Object is not reachable then ASA will perform the second NAT-Global operation.
 
Also can we have default route pointing to Outside interface (primary ISP router) and in case of primary router failure it will point to secondary ISP. Do we have "track"  in the static route commands on ASA.

Cisco Firewall :: 5510 Security Plus To Terminate Client VPN Access For External Support Team

Aug 7, 2012

I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
 
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
 
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
 
3. does the CSC module provide any web proxy functionality?

Cisco VPN :: How To Use ASA 5510 To Terminate A LAN To LAN IPsec VPN

Aug 6, 2012

We have an ASA 5510 running 8.3 that we need to use to terminate a LAN to LAN IPSEC VPN.
 
Problem is we only have one public address available so have had to configure the link between the ASA and the Internet Router on private addresses.
 
Is it possible to NAT the public address to the inside or outside interface of the ASA and terminate the VPN on that interface?

Cisco Firewall :: ASA 5510 - Routing Between Interface

Mar 26, 2013

I have a WAN interface and 2 LAN interface. I need both the LAN be able to access a server outside the network via the WAN (outside) interface. I am using a ASA 5510 firewall instead of a router, because I don't have a router. It looks simple enough but it does not work. I ping from the a PC (172.16.22.8) connected to LAN (inside) Network to 10.10.10.1 which is the WAN local interface also did not work. But from the ASA Firewall, I could ping my LAN (inside) PC. I followed a config i get from this forum. However, it did not work. Below my config.

I'm not clear about the capabilities of the ASA 5510 GigE interfaces (eth0/0 and eth0/1) with an without IPSEC tunnels enabled.
 
This page [URL] shows a figure of 170Mbps 'Maximum 3DES/AES VPN Throughput'. Does that mean per IPSEC tunnel or for the whole interface if it is IPSEC-enabled?

Cisco Firewall :: ASA 5510 High Traffic On Outside Interface

Jul 31, 2012

I have little experience with firewalls, what I've learned has been by dealing with issues like this that arise from time to time.I know, I need to upgrade the version. It's in the works now. Anyways, my question/problem is: Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today.  On the dashboard of our asa 5510 the "outside interface" traffic usage is running contstantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.

Cisco Firewall :: ASA 5510 - Two External Subnets On The Same Interface

Oct 21, 2012

I have two ASA 5510 in an active-standby cluster, not that I think that the fact that they are clustered will be of any importance here so feel free to think of it as a single 5510. The internet connection is delivered in a single RJ45 connection. To be able to use it with the cluster there is a simple unmanaged switch connected between the ISP and the ASA's. I have two subnets with public addresses, for simplicity lets call them 1.1.1.0/24 and 2.2.2.0/24. Default routers are 1.1.1.1 and 2.2.2.1 respectively.
 
Can I somehow use both these subnets in the ASA's? Im currently using the first subnet and use PAT to direct traffic to internal servers. But if I want to use adresses from the second subnet wont that mess up the routing, since there is no way I can specify the default router for the second subnet? I have as of yet not tried anything, Im just trying to plan ahead and I cant seem to wrap my head around how this could possibly be done.

Cisco Firewall :: Cannot Ssh Or Ping ASA 5510 From Inside Interface

Apr 4, 2012

The ASA is configured in very simple transparent mode. As desired, traffic can flow in each direction between inside and outside. I can manage the ASA via console and direct connection to the management interface. The problem is that I cannot ping or ssh to the ASA via the inside interface. I need to be able to manage the ASA from any PC on the inside LAN. I suspect I am missing some easy aspect of the configuration but after a lot of hours I'm about at the end of my patience with it. Here is what I believe to be the relevant parts of the config. 
 
ASA Version 8.2(1)
!
firewall transparent
hostname issr1
enable password 2alej83t5cqT0FWd encrypted
passwd 4kleUY438I93.4ljdh encrypted

Cisco Firewall :: ASA 5510 Inside Access To NAT IP On Outside Interface

we have a server that has an outside IP and an inside IP. It's inside ip is 192.168.222.30/24 and it's outside IP is 199.204.50.2/29. The connection to this server from the outside is perfectly fine, but access from inside users to the NAT'd IP which is 199.204.50.2/29 is having issues, however, access to the inside IP works fine (this part makes sense)Will It be a must to set the inside DNS A record to the inside IP and not the outside IP, or can users on the inside interface access the NAT'd IP which is assigned to the server
 
LAN(192.168.222.0/24)<=====>InsideASAOutside<=====>(Server with NAT IP 192.168.222.30/24, it's also physicall assigned to this server).This is an ASA 5510 with 8.4.
