I would like to connect devices to my network so that their traffic passes through a proxy running on my computer. I figured the best way to do this is by setting the proxy on my router to the one I am running, but then I would need to have another connection to the computer running the proxy or else there would be an infinite loop ?? something like that. so:
Internet -> router (1) -> my proxy on comp A -> router (2) -> computer B

I access the internet from my company�s LAN, which has a restrictive firewall, so I cannot request the admin to open any ports manually for me. Hence I use a software called your-freedom. This proxy software supports both http as well as socks 4 and 5 proxy (by entering the proxy IP 127.0.0.1 (localhost) and Port 8080 for http proxy OR 1080 for Socks Proxy), and I have successfully been using web browsers and some other softwares that support proxy/ allow proxy info to be entered to login/ connect to the internet. Your-Freedom also supports port forwarding.However, the softwares I intend to use do not have any options to enter proxy methods or proxy ports (as far as I have noticed). I have tried to proxify these 2 softwares using softwares such as SocksCap and Free Cap, but either they don�t work, or my settings in proxifying are not correct. I believe I will have to do port forwarding or proxify the softwares, but have been unable to do so in the correct manner.
Following is the info on the 2 softwares:
1.NOW Trading terminal:[FONT=Times New Roman]Normally when I start the NOW or Zerodha software, the software starts and I get a login screen, but under firewall conditions, I get the initial Splash screen but then the software stops with the error: [b][u]NOW Initialisation failed for Interactive Engine << os error>>.
2.PowerIndia Bulls:The software is written in Java and starts with a batch file (PowerIndiabulls.bat) located in C:UsersDEFAULT_USERNAMEAppD..... I converted this batch file to .exe (with battoexe software) and then ran it through a proxifying software. The .exe start properly without proxifying software but not under proxifying environment. Basically the software needs to connect to the internet using Port 443. I am also expected to keep ports 443, 41599 and 59598 open. software's requirement is available at Indiabulls Securities: Indiabulls Securities is a leading capital market company offering securities broking and advisory services, depository services, equity research services to its clients in India. (item no. 5).To confirm, while the software is unable to connect through port 443, you will get an error message: "Connection to Login Server could not be established" when you try to login with any random Username and Password.To know that the software is able to connect properly, you will get an error: "This User ID is not enabled to be used with this product".

At the moment we have all our users going through a Proxy Server, Microsoft ISA but I want to know whether I could scrap this and utilise the ASA.
Would it be possible to create a Network Object with an IP range (Domain Users) and then have a list assigned to this of any Websites not permitted?

I have recently been having a very annoying problem with my internet connection. I am not able to connect to some websites: the sites that are unavailable can not be accessed on any device connected to my home network (wireless or plugged directly into the router). I know that the problem does not lie with the sites themselves, since they are working for other people, and I know the sites are not blocking my IP, because when I reset the router, the problem sites become accessible but other sites become inaccessible (on all devices). The problem isn't the router either: I've tried two, and the same problem has arisen with both. Moreover, I have established that the problem does not lie with DNS resolution. I have repeatedly flushed the DNS cache; DNS lookups work fine on the problem sites, but when I ping the given IP addresses I am getting some packet loss (not necessarily 100% loss). When I use a proxy, I can access the sites without any problem.

my internet connection has dynamic IP. So when I download some file from file sharing site, and if my internet connection breaks, my download can't resume from where it had stopped since my IP adress is changed.But if I stop the download manually (without breaking internet connection), as the IP address remains same, I can resume the download from that point. I mean can I use a proxy server so that everytime the download resumes, it reports a constant (static) IP to the website?

I'm planning to migrate a customer from ACS 4.2 to ACS 5.3.
I have migrated the configuration for all the services but I'm thinking how to configure ASA 8.4 cut-through proxy service in TACACS+.
The same ASA uses TACACS+ for device mngt and RADIUS for vpn remote-access services.

We have a custom web application which is heavily relying on javascript. We're trying to access it via the webportal but this application does not load correctly (it barely shows a white page).
the link is [URL] and SUBIF-ISP2 is the public interface facing the internet. This is the rule as displayed by the CLI:
proxy-bypass interface SUBIF-ISP2 path-mask oursubdirectory target [URL]
Despite having this command in place, nothing changes. I tried multiple combinations adding the xml and hostname rewrite or changing the interface but nothing, the page is the same like if this rule was not applied.

I am using a squid proxy behind an ASA5520 firewall to collect the users to the internet. Squid is just necessary to log what is going on in order to find a quick solution when the internet slows down.
Considering that I have unlimited licenses and I would like to get rid of squid, I wonder if the ASA has some functionalities to track which websites are being used and how much traffic is generated. If there is not, I would like to know if Cisco offers a good product to replace Squid.

I have a Dell Inspiron E1505, I am currently in France and trying to connect it the University's proxy server, and I have followed ALL instructions provided by the university as to how to go about doing this. Each time I enter the proxy address and everything and it doesn't pop up an error message or anything like that, it simply doesn't connect to the internet or give the opportunity to input my password and username.

I have an issue here, I need to connect to various anonymus proxy servers, the ip's of which can be freely found on the web. I've tried doing this from a broadband connected computer and it's ok, but the thing is that when I try doing this from a computer that is tied to o router, it doesn't work at all.

I was recently trying to access , a free Japanese Internet radio service. It is region locked (ie. Japan only).I've used Japanese VPN and proxy to try and bypass the lock, but somehow it (the website) knows I'm based in UK (which is where I live). Even through VPN and proxies, is it possible to know where the IP is based?

i want to acces the video content of the Dutch television channels, but i am living abroad, they track the ip, see i am not in holland and dont show the content. There are some companies providing a vpn subscription in the Nethderlands for 15 Euro a month and that works perfect, just its a little expensive. Now my hope was to buy a seccond hand vpn router, that i want to put at my parents place in holland, and some how use it in the same way as the vpn service of the company. So using it to connect, and browsing trough this connection to get a Dutch ip.

I can't access some sites, loading times are endless and they look totally strange when I can access them (No images and so on). Sites are completely random, some examples are GamersLegacy.it - Starcraft 2, Diablo 3, Dota2, World of Warcraft, League of Legends, Inferno eSports - Homepage (videogames forum)FINECO: Conto, Investimenti, Trading, Prestiti e Mutui - Banca diretta, online o con promotore (bank) Sigma Draconis
1) Cleaned laptop with Ad-aware and Malwarebytes, found 2 issues but didn't fix the problem.
2) Closed firewall, nothing either.
3) Canghed/flushed DNS, tried both openDNS and GoogleDNS, nothing.
4) She CAN access those sites, she has same connection to the router (via wireless) and she has same OS (Windows Seven). I think that means it's my problem, not a router one.
5) Tried to lower MTU settings in my wireless connection as I read that could be the problem, nothing new here.
6) Here comes the tricky part. I tried to access those sites via proxy (Ninja Cloak | Fast, free, anonymous web browsing with NinjaCloak.com) and they actually work!

We just recently upgraded a 5540 ASA running 8.2 to a 5555 running 8.6. I have a question concerning disabling proxy ARP with static nat rules in place. We have several instance where devices in a dmz have a static nat entry to the outside and a static nat entry to the inside using the same IP. My question is if we disable proxy arp on the inside interface would that cause device on the inside not to be able to reach the device in the dmz? From what I have seen you don't want to disable it on the outside interface due to all the static nat translations. But we have some that are have nat translation going to the inside as well. How does proxy arp come into play there? Below is a diagram of an example of the setup I a referring to. This is on the new 5555 running 8.6
