Sep 12, 2011Running ASA 5510 with code 8.3 in it.We have our few https portal and OWA websites in HO.We access these sites from the network behind the ASA.All works perfectly fine.
In order to have control on internal network traffic we placed a web-filtering device (Fortigate) in transparent mode.To start with of we haven't blocked anything via new box but https portal and OWA stopped working from certain computers.At the same time other https sites were reachable from the same computer/s.We checked that website was tracable using traceroute from ASA,Fortigate and even from interal computer(from the one which it is not opening).This behaviour is random.

Cisco Firewall :: ASA 5510 HTTPS Filtering Bog Down
Feb 15, 2012I am running a Cisco ASA 5510 with Trend Micro Interscan. We have it set up to filter https except for a handful of sites. It is filtering the ones we don't want ie: facebook, and youtube. Though it is causing all other https to slow to a crawl. Therefore some sites it times out on us. What should we be looking for to change so it isn't slowing the allowed sites down?
Version numbers
ASA - 8.4(3)
ASDM - 6.4(3)
Trend - 6.6.1125
Cisco Firewall :: Open A Port In ASA 5510 Firewall Using ASDM?
Oct 20, 2012I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.

It then cuts me off.

Cisco Firewall :: ASA 5510 Filters URLs In HTTPS?
Nov 22, 2011My company uses a pair of 5510 ASAs as the gateway to Internet. I once configured policy-map to filter certain webpages (facebook, twitter, ...etc) and they work fine. However nowdays those websites all support HTTPS. In the https the URL seems encrypted so can't do regex match... Is there anyway that I can still block those webpages?
Another two ways I can think of are
1. Block IPs (don't really want do this unless absolutely necessary)
2. Block DNS for the URL (however they can work around by setting static DNS entries)

Cisco Firewall :: ASA 5510 - Cannot Open ASDM
Mar 20, 2011We are running a Cisco ASA 5510 in our district. We have been using it for about a year and a half after an upgrade from our PIX. I have been using the CLI to manage it but I wanted to start using the ASDM. I installed the ASDM Launcher last Friday but could not access it. I have enable the http server on the ASA, assigned an IP to the interface, and granted my machine's IP inside access. On Friday I was unable to launch the ASDM. I then downgraded Java. I came in this morning and was able to connect through the launcher. However I could not make any changes as it would give me an error message and often popped up with "lost connection" type messages. I then closed the ASDM but could not reconnect after that. When I try to connect through the launcher I receive the message "Unable to launch ASDM from 172.16.5.1: Connection reset". When I try https://172.16.5.1/admin/ from a browser I simply receive "page cannot be displayed". I'm not sure why I can't connect.

Cisco Firewall :: ASA 5510 - Graph In ASDM
Aug 28, 2012Running Asa5510, 8.2.5, with asdm 6.4.5 and I am looking for a graph in asdm that will show me what protocols and internal ip addresses uses the most traffic. Maybe a bit like "Top 10 protected servers under SYN attach". My reason for this is of cause I see a very high traffic pattern from one of my interface during the day and need to identify what is using bandwidth, protocol and source address.
I could use Net Flow feature in the Asa, but it´s not "real time" and forces me to setup a net flow collector. Can 8.2.5 not give me this information with built-in graph/tools?

Jan 24, 2013I do have one other question first. What's the effect of the crypto key zeroize rsa command, and then crypto key generate rsa modulus 1024 while I'm SSH'd to the ASA? Can I do it? Or do i need to be consoled in or connected a different way?
ASA 5510:
ASA Version 8.4(1)
asdm image disk0:/asdm-641.bin
asdm history enable
http server enable
http 10.1.1.83 255.255.255.255 inside
http 10.1.1.82 255.255.255.255 inside
Shouldn't that right there be enough to access ASDM from either host .82 or .83? Because I cannot. But if I add http 0.0.0.0 0.0.0.0 inside, then I of course can.
Cisco Firewall :: ASA 5510 / ASDM Access With Remote VPN
Apr 18, 2012I have a cisco ASA 5510 that I have set up currently to access via ASDM through the Inside interface. When I VPN in using our older VPN server I can connect to it fine. I recently set up the ASA to also be a VPN server which will eventually replace the older server for our HQ. I noticed that when I'm VPN using the ASA as the VPN server, I can only ASDM to the public which I prefer not to allow. Access to the inside doesn't seem to work this way. What configurations if any would be causing this. I'm assuming it's some thing I need to adjust in the VPN configuration.

Jun 16, 2011i have an issue with ASA 5510.
I connect to the device - https:/interface
I see the options such as download launcher etc.
But.. whenever I click on this I get stuck
Internet Explorer gives "page not found"
Or at the foot of the page it says "unable to download statup_lr"
Firefox says cannot connect
It is running 6.2.5.53
I can connect if I go to a PC where I have already downloaded the ASDM launcher (from many years ago)
Tried Win 2003, 2008 and Vista, and Windows 7
Tried downgrading to Java 6 r 7. Can I download the launcher from the Cisco website rather than the device? If so where?

View 7 Replies View RelatedCisco Firewall :: ASA 5510 / URL Paths And Regular Expressions In ASDM?
Apr 2, 2012I've recently switched to an ASA 5510 on 8.4(3) coming from a Checkpoint NGX platform (let's say fairly quickly and without much warning ). I have a couple questions and they're kind of similar so I'll post them up. I've read docs about regex and creating them both via command line and ASDM, but the examples always seem to include info I don't need or honestly something I don't understand yet (mainly related to defining classinspect maps). If someone could provide a simple example of how to do these in ASDM that would be useful in understanding how regular expressions are properly configured. So here we go.
I know this is basic but I need to make sure I understand this properly - I have a single web server (so this won't be a global policy) where I need to allow access to a specific URL pathfile and that's it. So we'll call it est estfile.doc. Any other access to any other path should be dropped. What's the best way to do this in ASDM (6.4)? I think if I saw a basic example for this I could figure out next few questions but I'll post them as well just in case.
I have another single public web server (again this won't be a global policy) where I'd like to specify blocking file types, like .php, .exe., etc... again a basic example would be great.
Lastly, and this is kind of related, but we have a single office/domain and sometimes we get spam from forged addresses appearing to be from our domain. On Checkpoint I used to use its built-in SMTP security server and could define if it received mail from *@mydomain.com to drop it because we would never receive mail externally from our own domain name. I saw something similar with ESMTP in ASDM and it looks kind of like how you set up the URL access mentioned above. Can I configure this in ASDM as well, and if so how?
Cisco Firewall :: No ASDM SSH Access To Inside Int Across L2L Tunnel In Asa 5510
Jul 19, 2011So I've run into a problem on my ASA5510, post-upgrade I can no longer connect to the inside interface from across our L2L VPN. I've tried both ASDM and SSH and the connections fail. I see in the logs that the attempt is being made, but it will eventually time out. There have been no problems with this type of connection with any previous upgrades, just this particular upgrade, I went from 8.4(1) to 8.4(2). I don't see much in the release notes or anything in a pre/post config diff that jumps out as a cause to this behavior. The only thing I did see in the release notes "CSCtg50770 Mngt-access (ASDM,SSH) to inside intf of 5580 fails over RA VPN session" which sounds like it could be my problem, but that was in the "Fixed in 8.4(2)" section and says it's for a 5580, maybe the fix for the 5580 broke it on a 5510??? I hope not and that I'm simply missing some new setting that I need to enable for this type of connection as this device is in a remote office.
