Cisco WAN :: ASA 5520 (Interface 1 And 2) Connection Settings

Feb 6, 2012

I have attached setup like this  :- This is the same scenarios as ASA with Dual WAN setup. But my requirement is different. I have added in ASA and configure sla is asa, all working fine. When one link goes down traffic pass through backup route. my sal config is below:-

sla monitor 100 type echo protocol ipIcmpEcho 10.5.5.120 interface Link1
num-packets 3 frequency 10
sla monitor schedule 100 life forever start-time now

show runn routes are :-
route Link1 10.5.5.0 255.255.255.0 10.4.4.5 1 track 10
route Link2 10.5.5.0 255.255.255.0 10.6.6.5 254
  
Is there any way that i can implement track on 2nd link to destination? because may be after Link1 failure when backup route was it would be able pass traffic to destination, may be link failure between Link router and Destination. Can i monitor backup link if that is active and traffic can pass to destination when 1st Link1 will fail.

Cisco Firewall :: Edge Router Connection For Outside Interface Of ASA 5520

May 1, 2013

We have ASA 5520 firewall.For broadband Internet access, we have T1 Router(edge router provided by ISP) which provides public IP's 198.24.210.224 / 29. We have usable public IP's 198.24.210.226 - 198.24.210.230 with default gateway 198.24.210.225. We assigned 198.24.210.230 255.255.255.0 to the outside interface.
 
If we connect the ASA 5520 outside interface directly to T1 router, can all packets with destination addresses 198.24.210.224/29 reach the outside interface without using other device like another router or switches?I just assume that only packets with destination address 198.24.210.230(outside interface ip) can reach the outside interface from the edge router.Is it wrong assumption?  If it is correct, then is there any way to route all packets with destination address 198.24.210.224/29 to the outside interface?

D-Link DIR-615 :: Game Keeps Disconnecting - Suggested Settings Missing From Web Interface

Apr 9, 2013

I keep getting disconnected from the game "Vindictus". I'm not sure what protocols it uses, but it shouldn't require any configuration on the Router, since it was working fine before. I upgraded the firmware to 4.13 in an attempt to fix the issue, but it didn't work. Some people have suggested "Endpoint filtering" to be set to independent, but I cannot find such an option. Where is the option? I was told it was on the Firewall page, but it is not there (Advanced->Firewall/DMZ). The router is supplied by Virgin Media (ISP) but I'm not sure if that matters.

Cisco VPN :: ASA 5520 VPN To Outside Interface?

Mar 20, 2011

I have a 5520 VPN that is otherwise correctly configured for access (so I would say).  It is in test (external IP x.x.x.10/22) running parallel on an external switch to a Check Point (x.x.x.4/22) that is the live setup.
 
I can tunnel consistently to the outside interface on its external IP from inside the network, which is probably natural since I'm inside the network making the attempt; however...
 
When attempting connection from somewhere outside the network, I generally do not get response from the device.  If I connect/disconnect from the Check Point VPN first, then I can subsequently get a connection to the ASA.  I did actually have one instance of non-massaged connectivity to the ASA, but there was nothing that I did in the configs that would allow me to claim credit for that instance.
 
So here's the question:  Is there a timeout setting that makes the outside interface go to sleep or something?  I'm still at the developmental stage where settings that would be obvious trip me up for hours.  I verified the routes.  the timeout configs are below; I believe they are all default..

arp timeout 14400
!
timeout xlate 3:00:00timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolutetimeout tcp-proxy-reassembly 0:01:00

Cisco Firewall :: Add Second IP To Outside Interface Of ASA 5520?

Nov 15, 2011

We have a block of addresses assigned to us by our ISP.  We need to assign one of these addresses to a vendor we use for traffic to one of their internal devices.  Lets say the address we gave them out of that block of addresses is 1.2.3.4
 
How do I add that address to the outside interface so that when traffic s sent to it that the traffic actually gets to the ASA as right now when we send traffic to that address it doean't make it to the ASA.

Cisco Firewall :: 5520 - Cannot Ping Through Outside Interface

Feb 3, 2013

I cannot seem to ping from the outside of my 5520 firewall to an inside network. I have a single physical outside interface connected to a Layer 2 switch, with a laptop connected to it. This is on network 10.11.131.0/28. From there, I cannot ping to the inside interface (which is a sub interface on G0/0) with network 10.11.130.0/24/ For some reason, it doesnt work.
 
Now. I had access-lists in place, but have removed them for testing and it still doesnt work. I have set the security level of inside and outside to 100, and entered the same-security-traffic permit inter-interface command - still no joy. Below is the relevant configuration.
 
Inside Interface
interface GigabitEthernet0/0.96
description L3 Interface - Informational Zone

Cisco Firewall :: ASA 5520 Interface Overrun?

Feb 23, 2011

Recently our network experience a Internal DoS attack. One internal server ( the network/security team doesnt have any access to the adninistration of these server) starts to send a lot of DNS bogus request to some DNS servers on the Internet. With sh conn detail we saw the IP of these server and blocked it with an ACL in the Internal ASA 5520 interface. After that, the server team disconnect the server, and made their job cleaning these infected device.  Everything goes normal again....
 
 Today, the same server starts again with the same problem. But a lot  worst thant the first time. The ASA starts to drops packets in the internal interface, the overruns was increasing dramatically ( like 10000 per second), the asp-drop table shows the same amount of traffic than interface overruns in the ACL-Drop line , and the CNT blocks for  16xxx with sh blocks was in zero. The sh acess-list INSIDE shows near 9 million hints in the line that deny the DNS request from the server to the Internet. Again, we disconnect the server and the problem was solved by the server team.
 
 It seems that our ASA cant handle in their internal interface the amount of traffic that these server send outbound. IS there anyway to raise the blocks in the firewall?  What is the best way to deny the servers connections ( ACL, or MPF or threat detection maybe), and avoid the ASA interface overruns even when the server sends these large amount of request.

Cisco VPN :: AnyConnect On Inside Interface Of ASA 5520

Aug 18, 2011

We currently have a setup where users connect to the inside of a firewall using the ipsec client. We are moving them to the anyconnect client but are unable to get it to work, we cannot even get a webvpn page on the inside.

When trying to connect with anyconnect the ASA reports an IKE initiator fail on the inside. and no tcp connection flag. We cannot get any response with Webvpn either I have tried using a different tcp port on webvpn but then the asa denies the traffic even though there are no rules denying.

Cisco Firewall :: ASA 5520 - Flags SYN ACK On Interface Dmz1

Jul 12, 2012

I know this issue probably has been beat to death, but I have yet to find the answer to my situation. We recently upgraded from a PIX515e to ASA5520. Shortly after the install I noticed a problem with the servers on our DMZ. This problem was NOT present with our old 515e. The problem is that there seems to be a communication problem between servers on the DMZ, specifically when I try to open the web server homepage from my mail server, I get time-outs. When I ping between the two in either direction, I get time-outs. This might seem trivial, but I have other data servers on the DMZ that need to communicate between themselves.

When we question the tech that performed the install, his answer was that there might be a problem with the switch the servers are connected to, or the servers might have a virus. He stated the process of ping should never involve the DMZ interface. And yes, our DMZ interface IP is the gateway for the servers. Now, if the DMZ (ASA) should never come into play with a ping, why when I turned on logging did I receive the error below? It sounds to me that the ping is going through the interface. Here are a few of the errors on the DMZ with the specific server IPs.
 
july 13 2012 12:50:04 106014 10.10.0.10 10.10.0.5 Deny inbound icmp src dmz1 10.10.0.10 dst dmz1 10.10.0.5 type 8, code 0
 
The ping problem was only used as an example the demonstrate that there is a comm problem on the DMZ. ASA is running in router mode.

Cisco VPN :: 5520 - Traffic Enters One Interface And Forwards To Another

Apr 19, 2013

I am building a new VPN Anyconnect solution. I want the traffic to enter a interface and that traffic should be forwarded to my "VPN-Machine".
 
The system is a ASA5520 with old software, I am not at work now so i cannot tell exactly.
 
So my question is, how do i make the traffic enter one interface and being forwarded to another? I have splitted the physical interface to several sub-interfaces.

Cisco WAN :: ASA 5520 - Routing Based On What Interface Traffic Comes

Mar 26, 2012

We have an ASA that has 3 IPSEC VPN tunnels and standard interenet trafic coming in on Int E0/0 that I need to have go out Int E0/1. E0/1 is directly connected to a Steelhead Riverbed 2020. The Traffic will need to come back out of the Steelhead Riverbed 2020 and into the ASA to Int E0/2. From here it needs to go out either Int E0/3 which is connected to a Catalyst 3560 Switch or back out Int E0/0 though one of the VPN tunnels. I attached a PDF with a diagram if that works.
 
The reason we are doing this is we have Riverbed's at all our locations and they need to talk to each other to optimize traffic. Is this routing possible any other way than PBR (Policy Based Routing)? I am of the understanding that PBR is not supported on the ASA or PIX.

Cisco Firewall :: ASA 5520 - Static Route To Inside Interface

Cisco Firewall :: Load Balancing Using Virtual IP On DMZ Interface Of 5520 ASA

Feb 21, 2012

We want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
 
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
 
These IPs are going to be NATted to all inside IPs.
 
Lets say our outside IP is X.X.X.X
 
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary. When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.

Cisco Firewall :: ASA 5520 - Second IP Range On Public Interface For NATing

Jul 9, 2012

I have a Cisco ASA 5520 (Ver 8.2(4)) with all four interfaces in use (Public, Private, DMZ, Local offices) and an IPS module, so there are no spare interfaces. I have used all of Public IP's on the current interface for various services (these need one to one mapping, so I can't port map mainly due to SSL certificate issues) and I need to add another Public IP range. The secondary option on ASA interfaces does not exist as on routers/switches and I need to use an additional non contiguous IP address range for additional services advertised on the Public interface that are NAT'd to be servers in my DMZ.
 
I have seen an example of adding a static arp on the Private interface to allow a secondary gateway to be used for outbound traffic, but I need to allow 14 new IP addresses to be NAT'd from the Public to DMZ and possibly also for outbound NAT'ing (from either Private or DMZ to the Public). I have a L2 switch between the ISP router and the firewall, so using VLAN's is not an option unless the ISP can be persuaded (highly unlikey) to add the seondary IP's as a sub interface with tagging. Anyway if this was actioned then we would have a massive outage on our current IP range during the transistion.

Cisco Firewall :: ASA 5520 Not Passing Full Interface Rate Traffic

Apr 12, 2012

I have an issue where our ASA 5520 is impacting upload (from LAN to internet) speed. We have a 100Mbps SDSL internet link and only see around 45-50 Mbps on the upload when going via the firewall, download is around 90+ Mbps so that is acceptable. I have tested a laptop connected directly to the internet router and that give near on the 100Mbps up and down speeds, but if I put that laptop on the LAN or directly onto the firewall interface I only see 90Mbps down and 45Mbps up. I have check that the interface speeds/duplex on the firewall, switch and laptop are correct and also checked there are no errors on the ports. I also turned off the IPS and that made no difference. In addition I have checked the CPU during download/upload (max): CPU utilization for 5 seconds = 9%; 1 minute: 3%; 5 minutes: 1%
 
In theory the 5520 should be able to cope with this throughput:

Cisco ASA 5500 Series Model/License:    5520
Maximum firewall throughput (Mbps):          450 Mbps
Maximum firewall connections:                      280,000
