LAN >; PROXY >; PIX >; >; >; Internet. How?
Hello
We use PIX 515E (and we are satisfied), but now I need Activate Proxy Server with some restrictions (user can´t download files .exe etc.).
Current setting: user has in Internet Explorer (for example) on the connection setting is checked "use proxy server" (192.168.1.151, port 3128) and all restrictions are applied successfully. BUT: If the user uncheck this setting - it can connect to the internet and no restrictions are applied on him - he can download whatewer he wanted.
On the old version of firewall (kerio winroute 4.2.5) I can put the packet filter rule, and only the user who put the proxy can connect to the internet.
Can you help me how I can configure PIX?
Thank you, Milan
Hello.. as the internal DNS is 192.168.1.2, you must allow access to this IP to talk to the DNS servers of the ISP.
access your lists looks like this:
access-list outbound01 permit udp host 192.168.1.2 host 194.228.2.1 eq 53
outgoing access list permit udp host 192.168.1.2 host 194.228.2.61 eq 53
outbound01 list of access permit tcp host 192.168.1.151 all http eq
outbound01 list of access permit tcp host 192.168.1.151 all https eq
make sure you nat the 192.168.1.2 host out.

LAN Proxy Server settings are not retained
I get an error of security proxy server credentials when connecting to Office365 from the local network connected PC Split HP runnng Windows 8.1. We use a proxy server.
When I check the control panel configuration, internet options, Connections tab, network, under the proxy server section settings button the box IS COCHEE to «use a proxy server for your LAN...» »
I uncheck the box, click on OK and it backs up to the Connections tab. In this tab, the box apply is grayed out (which may seem reasonable, given that the changes I made are on a screen of a level down on the LAN configuration screen.
Anyway, after a while and always after the system has been locked on in «standby mode", settings return to check a box to «Use a proxy server for your LAN...» »
The changes are simply not found. My user account is administrator.
Any solution to this setting removed by using a proxy server?
I solved it without defining the system to its default settings. Thinking that maybe it's a corruption of user admin role I added other roles to my user profile form which also have the ability / permission to make changes. Fact:
Control accounts of user/group/tab Manage User accounts / light tone my admin account / Advanced tab/advanced/users/select my account/member/added the roles of IIS_UISRS, network and Network Configuration operators. (not easy thinking for an average of fall through user)
all saved and accrued
Once this is done, the Lan Proxy settings have been stable.
However, a prior problem with the audio still exists. The default value of the audio device continues to change speakers on the 2nd screen rather than the laptop speakers. I can make changes and he returns back from a seemingly random way. HP, a system Dingo! Maybe a bios update will fix.

Easy switch of the LAN proxy server settings?
In order to access the internet at work, I need to go through a proxy server. But whenever I get home I have to turn off the proxy server. So, whenever I go home at night I have to click on 'Internet Options' (shortcut on the desktop), then "connection", then "network settings" and finally uncheck the box "use a proxy server for your LAN". And then every morning when I get back to work I have to do it again and re-check the box.
Is there a way to make a shortcut directly on the screen 'network settings '?Better yet, could I get a click button to switch the proxy on and out, directly from my office? Does anyone know all the gadgets that offer this feature?Hi Taikoman,
Please use the forum for Support of Vista,
Please use your favorite search engine and do a search for "switch proxy on and out". You should be able to find an editing software to do the job.
NOTE:
Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.Hope this helps,

get anonymous on the Internet - how?
How can I be incognito when you surf the Internet, which is not allowing the sites I visit to know me.
It is difficult to be completely anonymous, there are many technical sites can recognize you. In Incognito or private browsing mode, Firefox does not distribute the cookies that have been set in regular browsing windows. However, sites can still learn your IP address, plugins and optionally data stored by Flash Player.
To hide your IP, you might consider a private VPN or TOR service.
To manage what plugins are listed then to ask Web sites, you can change an internal preference (plugins.enumerable_names - he is not very good documentation on this subject at the moment, but this article has more information: http://www.ghacks.net/2014/07/11/hide-plugins-visited-links-webrtc-we...).
To control the access and the use of Flash local storage, you can try an add-on like BetterPrivacy.
Of course, block sites of information normally find available can break some of them...

I downloaded malware to microsoft. Later (Odile is one). My problem is: if I start the laptop (XPS M1210) normally, when I want to start "Odile" - "Microsoft tool emergency response" (which seems to be the solution), the "personal shield pro 2.2" attack the computer and prevents all extra work." If I do it in safe mode, somehow it doesn´t enter the networks, as a result, programs to clean the scan only partially. No solution. I also tried to use "MS support tool for emergency response. Other programs are Loaris... work partially in safe mode (without ilnternet) and well in its entirety, but stop as soon as the malware takes over.
I think, I need to have the computer is running in safe mode with networking, but how do the internet to work in safe mode? any other ideas?
sincerely

Cascading the WRT54G2 BEFSX41 lan - LAN. No Internet access.
My kids each received a ipod touch so I thought I would add a WRT54G2 to my existing wired network that uses a BEFSX41 as the gateway device to provide access to the internet.
I followed instructions from Linksys lan - lan waterfall, defining the WRT54G2 as IP 192.168.1.2 as the BEFSX41 is 192.168.1.1 and connecting port 1 of the BEFSX41 to port 1 of the WRT54G2.
Ipods to connect to the WRT54G2 and I can access the control panels for each router to my computer (XP) using their assigned IP addresses.
But the iPod can not connect to the internet and the WRT54G2 cannot ping external IPs.
Where my Setup seems to differ the intructions of Linksys, is they claim all the WRT54G2 to use "Automatic Configuration - DHCP" as the type of Internet connection while the BEFSX41 has disabled DHCP and all the network devices have a manually assigned IP address.
Any advice would be appreciated. Thanks in advance.
Guessed it.
I had enable DHCP on for the BEFSX41 and set the IP address of the DHCP beginning to a value greater than the static IP already in use.
IPods are now cruise the ' net.
