I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

For example, if i generate a icmp traffic from interface inside to outsite, the ASDM does not show the packets, when it shows it apperars just in one direction.

My network is on a 101.140.228.x ip scheme because that's what the wireless network is set too and we can't change that. (It's built into the hub and the manufacturer doesn't let us change it. The computer I am having trouble with is cabled into a Netgear Access Point in client mode. The Access Point is working basically like an oversized network card to pick up the wireless network across the field with the 101.140.x.x ip.

View 14 Replies View RelatedMy computer is a inspiron 17r and is only a month old. for the last week or 2, it has been disconnecting from the internet while at home. The computer says it has an internet connection and is discoverable on the LAN, but will not connect to the internet for browsing, email or any other internet activity. I can restore the internet by rebooting the computer, or by rebooting the router and modem, or by deleting the network and re-establishing it through the network sharing center. Any of these will work, but somewhere between 1 minute and several hours, I will again lose the internet. I have several other computers and devices and none of them lose the internet so I know the router and the modem are fine. This also ONLY happens at home. I take the computer to work and connect with no problems and stay connected for 9 or 10 hours.
I have looked for answers and have tried ip release and winsock resets. these also work for a period of time but eventually fail as well.
I have been configuring a cisco ASA 5520, everything is working fine but when i create an ACL:
-access-list OUT extended permit ip 172.16.x.x 255.255.255.0 any
-access-group OUT out interface outside
i added ports like www or 443 and it is not working to Internet access a router is before to my firewall connected to my headquater, i can see my private networks but i cannot able to reach Internet access,
I have two 5520s in a failover configuration. When browsing the internet behind them the speeds average 0.5Mb/1.0Mb Download/Upload. When bypassing the ASAs the speeds increase to 4Mb/6Mb. I have checked the interfaces on the ASAs and there are no errors, collisions, drops, etc.

View 10 Replies View RelatedI've got what is probably a very basic question - but i can't figure it out.I have: Internet (ADSL) -> 2851 (ADSL wic) -> 5520 -> internal LAN (192.168.1.x/24)
The asa has just replaced a Checkpoint firewall.I've set up the ASA to the point where all hosts on the internal LAN have internet access (using a dynamic PAT on that network). This all works well.
The problem i have is i am trying to allow access from the internet to an internal host on a specifc TCP port (as i had done on the Checkpoint) but i'm getting:
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:111.111.111.11/52135 dst inside:192.168.1.252/5555 denied due to NAT reverse path failure
From what i have read i need to add a NAT exemption for this particular use case - to avoid the dynamic NAT i have setup, but im not sure how to do so.I'm running 9.1 on the ASA, no VPNs yet. Just this basic setup.
I am new in ASA, I have the DMZ (10.1.1.0/24) configured on ASA 5520 and I achieve the reach Internet from DMZ (10.1.1.0/24), but now need reach DMZ from inside (172.16.12.0/24) and inside (172.16.12.0/24) from DMZ (10.1.1.0/24), in other words round trip.

I tried to create a VPN IPSEC to test but when I finished the wizard I lost the conection between the inside interface and outside. I use other interface for DMZ and other for printers network but this adapters are working properly. I have reviewed the NAT's and the ACL's but I don't see the problem?
I have delete the VPN IPSEC but it's still not working and I have the network down
When remote workers - working say from home connect into the company's LAN via an ASA5505, is it then possiable to then go back out to the internet using the ASA as the gateway to the internet.It works if I point towards an internal proxy server.

Bu once in a while even with just a modem connected to my computer I can't use the browsers. The signal from the router to my Xbox 360 works but sometimes it says there's DNS Error or IP Address Error causing my Nat to be strict. Once in a while, I can access my router's page when it's connected. [code]
View 19 Replies View RelatedYesterday I picked up a laptop of a friend of mine which had some problems with the Internet connectivity. Turns out, Internet only works when booted in Safe Mode, however, it does ping in Normal Mode so there is connectivity. Tried IE and Firefox, both do not work in Normal Mode and do work in Safe Mode. MSN Messenger won't work in Normal Mode either. After carefully checking the Windows event logs, it looks like some services are not booted in normal mode.I have executed the following steps and measures in order for me to see if I would be able to fix the problem myself.
1) Boot in Normal Mode:
- Checked the settings of the adapter, no exclamation marks or other problems.
- Installed Revo Uninstaller Pro > Uninstalled all present antivirus program
- Installed Microsoft Security Essentials
- Ran a Full scan with Microsoft Securty Essentials; 1 virus > removed (just a virus which gives pop-ups)
- Installed CC Cleaner, cleaned the whole system
- Shut off all antivirus programs, IE and Firefox still not working.
2) Looked for extra information:cmd > Ipconfig/all Normal Mode [code]
So,I'm living in a university campus and I've got an internet connection via a proxy server.The thing is,when ever I plug in the network cable,my PC recognizes the network,but the little network tray says "No internet access". But the curious thing is that the internet actualy works.My browser works,I can access any website (well,except the restricted ones via proxy) but it works just like any other internet connection in the campus. But,recently I've got my hands on a VPN account to have access to things that my proxy wouldn't allow me (torrents for example).But,probably because of that "No internet access" problem,when ever I try to make that VPN account,it tells me that I need to connect to the internet first. I already am,but my PC still keeps requiring an internet connection.I can't manualy connect to it,since I don't have the ISP data required. I've only got my VPN account data (VPN username and password).
This is kind of annoying,since this only happens to me,my other room mates don't have this problem,they plug in their cables,their network adapters recognize both the network and the internet access. Only mine says "No internet access" but the internet works fine.My operating system is genuine,when ever I go home and connect to my home network this problem doesn't ocure anymore,this only happens when I connect to my university's internet connection.I've tried reinstalling my operating system.Still no results.I'll attach a printscreen so you could see exactly what I mean.
my internet is being slow. It 'uplink' speed is 7mbps. when downloading or just surfing the internet 'task manager' says that the computer is using below 5% of the internet's speed capasity. it never gets higher than this, is there any way to change this so that i can us the full potential of the internets speed.
View 1 Replies View RelatedWe use Cisco ASA 5520 (in HA configuration) connected to Cisco Switch 3750, ISP connection (25 Mbps) is straight to cisco 3750 switch. Since, Internet traffic is now high, a seecond ISP will be added.Our plan is to do Internet Link Load Balancing. My understanding that AS5520 can not do balancing.What appliance do you think I can use to accomplish the link balance?Also, take in consideration that our current ASA is also our VPN server and there are two DMZ zones.
View 1 Replies View RelatedOur internet connection is connected to an ASA. The download speed is ok but the upload is very slow. we have been running some speed test from our LAN, and have been also trying to upload/download file.
Our ASA also have the IPS module. I turned this off but we've got the same result.
I send here attach the configuration file of the ASA.
Used a pair of ASA 5520s in HA to firewall the internet edge and to firewall traffic between internal security zones such as web and application layers? If so, is this best done using different security levels or contexts?
I'm thinking of using a routed context for securing the internet edge and then using seperate contexts for the web and application networks. Contexts will route via a L3 switch.
I have CUWN, WLC 5508 is installed and APs are 1142. Network is working fine but I am facing the problem with Android phone which are not browsing for internet.
Android phones connectes with wi-fi, it takes IP from DHCP well, which is pingable from any node of network. even I got be GUI of WLC on Android, but when it goes to browes for internet the message displayed " Page cannot be disply".
In same scenario if configure the Public IP on Android Phone (Via DHCP or Static) then it runs the internet smoothly.
I'm on the ASDM of a 5510 and the logging with in the ASDM is currently set just right, but when I go into the console via SSH and use "term mon" I don't get this logging showing up. [code] As you can see I have set the ASDM and console to the same level. Currently in the ASDM I can see a user getting denied access to a device, but in the console view I dont get that, which I woudl like.

Administratration | Firewall | Firewall Logs, I can select any or all items. Where do I view the log?
I can go to Logging | Logging Policies and select everything for the 'default' policy.
No matter what, I go to Status | View Logs, and select whatever severity level I want but get little to nothing, and definitely no firewall logging.
One of our client has a Cisco IOS router 2851 with Zone Based Firewalls, enabled.
We tried to configure the router to receive the logs and we receive it in the following format:
