Cisco Firewall :: Fails To Download File Through ASA5540
Dec 12, 2011
We have ASA 5540 with 8.2 SW. We are trying to download a file (3 MB pdf) from https session which fails if done behind the firewall. In case, the client bypasses firewall, the file gets downloaded as usuall. Interesting thing here to note is that when client is behind the firewall, its takes a long time to download the file and the file size always 312 Bytes, of course its a corrupt file.
I am configuring an ASA5540 firewall for a client, only difference to usual being that it is to run in Transparent mode. I have looked through for an EAL4 transparent firewall config guide but found nothing and therefore assumed that the usual one would be used.The clients security bod has now come back and insisted MAC filtering should be used but I can find no reference of this anywhere. Does MAC filtering is required to make a transparent box EAL4 compliant and if so where I can find documentation supporting this?
I had a working vpn configuration between a local and a remote router; the remote router is not under my administration.Now I moved the vpn termination from my side to an ASA5540 software version 8.0(3). The tunnel is up but there is no reachability. The "show crypto ipsec sa" on the ASA shows encapsulated packets but NO decapsulated packets! Routing and no_nat are properly configured.
while downloading .avi file from internet, the connetcion got disconnected and the download could not be completed. How to locate that incomplete file in my computer and also is it possible to download the file from where it was disconnected?
I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary. Here are the log messages I got:
Mar 8 15:11:08: %PIM-5-NBRCHG: neighbor 188.8.131.52 UP on interface Vlan150 (vrf default) Mar 8 15:11:08: %PIM-5-DRCHG: DR change from neighbor 0.0.0.0 to 184.108.40.206 on interface Vlan150 (vrf default) Mar 8 15:11:11: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 220.127.116.11 (Vlan150) isup: new adjacencyMar 8 16:16:08: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 18.104.22.168 (Vlan150) isup: new adjacency Mar 8 16:18:54: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 22.214.171.124 (Vlan150) is down: K-value mismatch
I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?
I have this 2x ASA5540 firewall and notice the it is configured with a standby ip. The firewall is run in Active/Passive mode.However, the standby ip of this firewall is not point to the secondary firewall and vice versa for the primary firewall. [code]
1) May i know how is this configuration valid in the first place? I have checked through the configuration. None of the configuration is related to this ip address.
2) Can we remove this standby ip address on both the firewall and correct to the correct primary and seconadary ip address in both firewall?
3) We tried to use this ip address but cannot be used ? Is it related to the configuration of the standby ip address.Do note that the ping to this ip address x.x.x.120 is unreachable.
i have two CAT3750 need to place in L3, and it supposed that used as L3 switches by SVI for L2 routing, and I want to these two configured as redundancy by HSRP. but now I can only have one ASA5540 to connects these of L3 switches.
so, here is my questions:
1. does ASA5540 support multi vlan?
2. does it support spanning tree protocol?
3. if I've choiced to use trunking between two L3 switches, does it can pass through HSRP hello msg?
i try to upgrade acs 5.2 with the patch 5-2-0-26-1.tar.tar.Firstly it is not the correct extension when downloading the file from the download software area.then when I enter "patch install 5-2-0-26-3.tar.tar FTP" I get the following error message:
I am having difficulty uploading files on the internet because the speeds are so slow. My download speed is 23.88 MBPS, bu upload is .3 mbps. This seems to be a recent problem. The other computers on the network get upload speeds of 5mbps and do not have any problem, so I think there is some problem unique to this computer, and not a network problem. I can't back up my files because the speed is too slow.
Windows IIS server configured behind a Cisco ASA 5540 listening on port 443 currently. Access-list and static translation configured. I have been ask to redirect all port 80 calls to port 443 for this web site only at the firewall. I have suggested moving it behind our content switch with negative results. Can we do this at the firewall level? how to accomplish the redirect for a single site. 8.2.4 is current code
I upgraded our ASA5540 to 8.4, THEN noted the increased requirements for Memory. I purchased the 2Gig upgrade, but when installing in the Primary unit today, noted that there were 4 slots. Slots 1/3 had 512Mb modules, so I installed the 2 x 1Gig modules in slots 2/4.
The ASA5540 came up clean, and it "sees" the entire 3Gig of memory.
My question: Is this a SUPPORTED configuration? All documentation I have read only mentions 2Gig of memory. Also, If I had FOUR x 1Gig memory modules, would the ASA5540 support the 4Gigs of memory?
I have requirement received from one of my customer. the part number given as ASA5540-AIP40-K8, same time requesting for addition of another 4Port GE Module (i believe its SSM-4GE Module). Is any option to add this module in to the above specified model (ASA5540-AIP40-K8).
As per my understanding the ASA5540 have the option to add 1 additional module only, so if we AIP-SSM module, we don't have any free slot left with to add another SSM-4GE Module in the firewall.
i am not getting even the option to add SSM-4GE in the ASA5540-AIP40-K8
I am migrating firewall fortinet to ASA5540 with inside (192.0.0.0/24), dmz (192.168.0.0/24), and outside (x.x.x.x), but the users of inside network gain access to the aplication for two ways: the first way is trough routing between inside and dmz, for example 126.96.36.199 to 192.168.0.20, and the another way is trough static nat between inside and dmz for example 188.8.131.52 to 184.108.40.206 (192.168.0.20 static nat). Is posible in Cisco configure that? because when i configure only firewall route the first way is OK, but when i add the second way only nat is work!
I have an inside network using PAT to one outside address. Our DNS server is on another local, but outside address. I can't get the inside network to successfully get addresses.I have another inside address that just uses the wirewall and gets addresses just fine from the same server.I have the box checked in ASDN that enables DHCP on the inside interface and points to the correct DHCP server,PAT service is working properly if I use a hard coded address for a machine on the inside network.This is an ASA5540 with 8.3(2)
My Expertise with Cisco ASA is Very less. I have observed Input errors in a Couple of Interfaces in Cisco ASA 5540 Firewall. [code] I need to Clear the Input errors on this particular Interface.Will Clear interface GigabitEthernet 0/0 will work?
I am attempting to FTP to a remote site through a IPSEC tunnel.When I am transfering large files the ASA5540 is showing syslog errors stating "connection timeout". What I think is happening is after about 1 hour the firewall is closing the connection control port for the FTP session and neither end is notified so eventually the transfer is stopped.What do I need to modify in the FW to accommodate these larger files?
We need Solution for disabling Anti-Replay on the Firewall for a specific tunnel. ASA 8.4(2) ) does not support disabling Anti-Replay on specific Ipsec tunnel , is it true , then if we want to disable Anti-replay , what we have to do in ASA5540 .
I have a ASA5540 firewall set-up with an interface MTU of 1500.
I suspect that we are receiving packets with a larger MTU but have not found an easy way of confirming this. Any command that can be run on the firewall to display the MTU packet size being received on an interface?
We are also running Solar Winds so could query an OID if such a variable exists.
what´s going on with an asa540 configure in multiple-context mode. I Have a cacti server on my lan and now I´m try to monitoring the interface with snmp. When I try to get this information returns the error message:
CISCOASA/CONTEXTA# JUN 11 2013 01:52:00: %ASA-1-1-6021: Deny UDP reverse path check from 10.6.6.6 to IP_SRV_CACTI on interface inside JUN 11 2013 01:52:01: %ASA-1-1-6021: Deny UDP reverve path check from 10.6.6.6 to IP_SRV_CACTI on interface inside
If I try to ping returns the same error:
CISCOASA/CONTEXTA# JUN 11 2013 01:56:09: %ASA-1-1-6021: Deny icmp reverse path check from 10.6.6.6 to IP_SRV_CACTI on interface inside
Following attached the conf of my asa My question is Why I can´t ping or even use snmp ?
how can i discover product actual part number from the device through console.I have a bought a cisco ASA5540-AIP20-K9 and i want to check either is the product is shipped us as a right product.And i want to check total BoM requriements from entering the ASA console through any CLI Command.Below My Cisco ASA BoM which i purchased.

Is there a way to trigger stateful (or stateless) failover on ASA 55xx (8.0.3) when there's a failure on the IPS unit? I understand the fail open/fail close and its application on a single firewall, but the better solution for an IPS failure in a redundant pair would seem to be a stateful failover to the other ASA, and I don't see that as a documented feature.
I am having issues with monitoring our Cisco ASA5505 devices with "SolarWinds Orion NPM 10.2" through the use of SNMPv2. On some devices we see that SNMP polling stops and that the ASA's interfaces would show up as unknown - usually when the link to the device goes down/up or after a random ammount of time. At that point SNMP polling data is no longer updated and all we can rely on is ICMP for device status. I can resolve the issue by restarting the remote ASA OR restarting the SolarWinds server after which polling resumes. We are only seeing this behaviour with our remote ASA's.
Our setup is as follows: Head End: Cisco ASA 5520 [ASA 8.3(2)] Remote: Cisco ASA 5505 [ASA 8.3(2)]
I have found a SolarWinds article listed below that possibly identifies the issue that we are having but am not sure where to start.
The client is only interested to have one-WAN(MPLS) and One internet circuit with Dual ASA5510 primary/failover configuration. In the event primary firewall fails, there is no direct WAN/internet connection to failover firewall. I beleived that to mitigate the issue, I needed to add a layer 3 switch , and have each circuit (MPLS/Internet) or (modems/routers) connect to a L3 switch. L3 switch will do the vlan based routing based on the state of firewall. ? am i correct? The client want automatic failover to secondary firewall in the event the actual firewall failed without impacting the day to day business.
I have an ASA-5505 which I have been managing using ASDM from a PC and a Mac.I just happens that the Mac has not been used in a little while and when I tried to use ASDM on it, it fails.I've had a trawl through various posts and release notes (after updating various components in the process, incl Java with all the diabling/security updates of late) but am still having the problem and this is where I'm at:
- the ASA runs v8.4(2) and ASDM 7.1(1)52 - release notes state that ASDM 7.1 should work on Java 7 on Windows 7 and MacOS 10.7 - ASDM starts fine on my Windows 7 PC running Java 1.7.0_13 - I am also running Java 1.7.0_13 on MacOS 10.7.5 - on MacOS, ASDM starts, asks for credentials, download/refreshes the cached app... and then crashes with the following exception message:
The root cause of the issue seems to be that a Java class called apple.laf.AquaTableHeaderUI is not found..Now, I don't know much about Java, but that seems to be an Apple UI related class - I presume that it would be good to use this to give ASDM a more native look and feel, but why on earth is there no fallback? or am I missing something?
