Having some problems blocking users installing/using secure browsers proxy. Currently runing ASA 5520 ver. 8.3 & IPS SSM-20 7.0 (2) E4 & Websense web filtering. Able to block most proxy sites with Websense that use port 80 but recently found that some users using some products like Njutrino that use their own secure browser that use it's own proxy over SSL connection.

View 1 Replies View RelatedI have an ASA 5520 with the below config
Gi0/0: outside (Internet)
Gi0/1: inside (Internal users)
Gi0/2: DMZ (web servers, ftp, Mail etc..)
I have a SMTP relay deployed on the DMZ for mailing. I have also a mail servers installed in the internal lan,
I want to allow trafic from dmz to reach internal lan, and i want normally also allow stmp relay from dmz to reach Internet.
How can i block trafic from DMZ to reach Internal Lan (instead of smtp) if the to allow trafic from dmz to internet i must put ANY in the policy?
For allowing trafic from DMZ to reach Internet, the policy must be DMZ -----> ANY ----->Services., this policy means DMZ can implicity reach Internal Lan?
I have an ASA 5505 and I setup a port with a PC connected to monitor the LAN interface. I see all the traffic from the LAN going out and traffic coming back in no problem. What I do not see the the AOL Instant Messenger traffic at all. I have WireShark on the PC and I filter for AIM traffic and I see nothing.

Windows Messenger continually connects and disconnects. This behavior is permanent I only have problems with Messengers (all releases), web page access is correct. I check bandwith saturation and It's ok, I use less than 50% of each DSL. I configured the correct size of MTU for each DSL and the problem continues.Is there any way to set priority to this service? Is there any way to check if the "load balance mode" affect this kind of connections?

View 2 Replies View RelatedI have a wireless router Linksys WAG200G.Im having trouble since a few days for use Windows Live Messenger 2009. I tried some tips for correct (cleaned cache, uninstall and re-install the software, checked the firewall, programs related to the software, etc).I was thinking that this was a trouble with my computer, but was made tests with other 3 computers, that cannot connect too (and can connect in others wi-fi connections, in other places) and in the attempts are being generated the same error: 8100030d.Searching in the internet, i saw that the problem could be with the router.
I didnt made any changes in the router configuration, and are using this equipment since last 2 years without any problem. I didnt tried to reset the configuration yet. But tried to disable the router firewall, and the problem occurred again.I tried some tips in this forum, like changing the MTU and including ports of messenger in the router configuration, but it didnt work.

View 1 Replies View RelatedI'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
I have an asa 5520. How would I configure my dedicated management interface to be able to route off subnet while the firewall is in transparent mode?
