Cisco Firewall :: ASA 5510 - Web Interface And SSL VPN Pass Through?

Mar 1, 2011

I have a trouble with Cisco ASA 5510. I configured an SSL VPN with bookmarks to some application. When the users make access to the Web Portal they have to login twice: one for enter in the SSL and one for enter in the application.
 
How to bypass double authentication?

Cisco Firewall :: Pass Management VLAN Traffic Through ASA 5510 In Transparent

Mar 10, 2013

We have a small cisco 1800 series workgroup router that seperates our network from the outside world.  The data coming into our network goes into the router on interface fa0/1 and comes out on interface fa0/0.  fa0/0 is split into 2 sub-interfaces (fa0/0.2 and 0/0.3).  These sub-interfaces correspond to a desktop and server vlan on our network.  The workgroup router is connected to a 3560G trunk port (we'll call it switch 1) and switch 1 connects to another 3560G (we'll call it switch 2). Recently I was asked to add another layer of security to our network by installing an ASA 5510 firewall and forcing certain types of traffic to authenticate using their domain credentials for our network.  The firewall was set up between the router and switch 1 in transparent, multi-context mode.  There are 2 security contexts, 1 for the desktop vlan and 1 for the server.  Both have the same security settings applied to them since we want the same behavior regardless of whether they are trying to access the servers or the workstations.

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.

Cisco Firewall :: ASA 5510 Interface Throughput?

Feb 4, 2013

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 WAN :: 3825 Router Interface Does Not Pass Traffic

Mar 7, 2012

we have a Cisco 3825 router which does not work well with a DSL  modem(ISP provided). I have configured the Gi0/0 port of the router to  plug into this DSL modem but it does not ping to the ISP gateway. If we  do a shut/no shut on the interface then it work fine for about 30 secs.  Sometimes even for 1 hr. Then the packets drop and we cannot pass any  traffic through this interface.
 
Now, if the ISP connection is terminated on a computer it works fine. It works fine without dropping any packet.I  have tried various options like using a straight/cross cable. I have  tried to configure the interface negotiation for 100/full, 100/half,  auto/auto and almost all the options.I have also tried to interconnect the devices using a L2 device like a HUB. Nothing works.

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 :: 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

Jun 28, 2012

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.

Cisco Firewall :: ASA 5510 - Failed To Locate Egress Interface?

Jul 22, 2012

having a bit of trouble setting up our 5510.  None of us have ever played with a firewall before.  We've got most of the basics covered.  I was able to get to the outside world to do a software update to the box, but my laptop that sits in the inside can't see the outside.  We only have the default access rules in place at the moment.  Our old ISA firewall rules don't really translate all that well to this new box.

Cisco Firewall :: ASA 5510 Allowing ICMP Unreachable On Outside Interface

Oct 25, 2011

I am having some issues with my ASA 5510 (running ASA 8.2) dropping ICMP unreachable-fragmentation-required-but-df-bit-set type messages coming in on the outside interface. I have the following entry in the ACL for the outside interface:access-list outside_acl extended permit icmp any interface outside and there are no other entries in that list that should take precedence and drop the packet. Pings from outside to the ASA work when this ACE is present and do no when it is absent so it is clearly taking effect. I see the following entries in the debug log when sending a large non-fragmentable packet (that would cause an intermediate router to send back this ICMP response) out to the internet through the ASa,As far as I can tell I am not running ICMP inspection; I don't want it to do any stateful magic here since the outgoing traffic would have been ordinary data from another protocol and would not have caused an outgoing ICMP connection to be built to match against.
