Right now, in my network there is no proxy server and all users go straight through the ASA to access internet. I would like to put a squid with dansguardian (for web filtering). Steps in getting all http and https traffic from ASA go via my squid?
View 18 RepliesI need to redirect all http and https traffic from one source in a dmz network, to port tcp/8080 on a proxy server on the inside network.
The source device doesn't handle proxying very well, so i've been advised to redirect the tcp/80 and tcp/443 ports to tcp/8080 as it passes through the firewall.
Scenario is thus:
PIX 515E 6.3 (5)
DMZ server: 172.31.255.250 (Real IP), 10.44.181.236 (NAT IP)
Inside Proxy server: 10.44.132.28 (Real IP), 172.31.255.110 (NAT IP)
I've configured a static NAT redirect using the following command: static (inside,dmz) tcp 172.31.255.110 www 10.44.132.28 8080 netmask 255.255.255.255 0 0
When I try to add the next command of: static (inside,dmz) tcp 172.31.255.110 443 10.44.132.28 8080 netmask 255.255.255.255 0 0
I get the following error: ERROR: duplicate of existing static
Is there a work around for this at all or am I stuck with the limitations of the software?
i have the following scenario :
ISP1-------ASA 5510----------ISP2
|
|
|
LAN
i would like to use ISP2 for all http/https/ftp traffic.how could I force my ASA to set a different gateway for http/https/ftp traffic ?i have tried several solutions such as nat/pat rules, nothing seems to work.
I am using ASA5510 and i want to know if it is possible to redirect http traffic to an internal proxy software. I explain : PC from the LAN use a internal proxy in their IE browser but some other PC doesn't use it.They are directy connected to the Internet using the Public IP from the WAN interface ( via NAT). Can we redirected this HTTP Traffic from the WAN interface to the Proxy in the LAN ?
Http Traffic will be routed like that : PC -> WAN interface -> Proxy -> WAN interface -> Internet In fact,can we create a rule saying : All http traffic which doesn"t come from the IP Proxy must be redirected toward proxy.
For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
But if the CSS is already handling traffic for existing url... traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?
I am trying to make a redirect from http to https. the goal is whenever a user writes in http://10.80.199.71 it should be redirected to https://10.80.199.71 I am just haveing some trouble making it work.

View 7 Replies View RelatedI have an ASA 5505 that I am using to connect my contractors to via an inside interface, the outside interface is my private LAN. I have setup on our corporate Proxy server to allow traffic from my outside interface of my ASA to go to the internet without credentials BUT log internet activity. The question is I want to know if the ASA can send that http & https traffic to my proxy server and all other traffic to my default route? I want to be able to send all internet traffic to my proxy server. This will avoid me asking the contractors to place proxy credentials in their browsers.

View 2 Replies View RelatedOn a Catalyst 6509 switch I have configured wccp protocol in order to redirect the Http traffic to a Bluecoat SG8100. It was working fine until a new L3 interface implementation.Thereafter I was unable to redirect the http traffic due to an error reported from the Cat6509: [code] After some checks I supposed that the problem should be the UDP 2048 port connection between the Switch and the Bluecoat while the switch L3 port and the bluecoat are on the same Lan. A deep analysis found that the WCCP protocol seems to be as follow:
-Proxy address 10.64.28.240 to Switch Port 10.64.28.250 Here I Am
-Switch Port 10.64.28.250 to Proxy address 10.64.28.240 I See You
-Switch Port 10.66.0.251 to Proxy address 10.64.28.240 UDP 2048 packet (dropped by firewall)
It's strange to me that the first dialog is correctly handled by the correct Cat6509 interface while the UDP packets are flowing from another Vlan interface not configured with the WCCP and apparently not involved on the protocol.Last of all the WCCP is now disabled and unusable?
I have got a Cisco router connected to a LAN and to the internet.I was wondering if I could nat https traffic from inside to internet to a local server (Proxy) on a given port for example tcp 8080.

ip nat inside
int fa0/1

ip address 41.x.x.x.x 255.255.255.248
ip nat outside

Never seen a Cisco, or any other L3 switch before. Nor an Lx router. Any step by step,or class room or web based training, or a partner or Cisco helper to get us up to speed on this.Goal is to limit http and https traffic in favor of telnet to an AIX server and RDP to a Windows TS. Printing would be ahead of http/s and below the others.

Two days ago, we changed our old 525 with asa 5520 ( ver 8.2 ). Configuration is the same, except the version. It even retains the same global interface and static public ip address as the old device.All worked well during that period.Yesterday, one of the http applications , not tested other day, was found not to be working. To test, we switched back to the old 525 , however nothing was working when we did that.Does the static statement which actually does the translation for this application carry any arp problems or so.how can i check this problem.

The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https.

View 2 Replies View RelatedI have a TAC on this, but thought I would throw it out here too. We recently upgraded a 5520 to 8.4 code so HTTPS traffic can filter through the CSC. Well, it takes several attempts to pull up any https pages. Cisco thought it may be hardware, so I swapped out the CSC, but before I go through the hassle of moving licnese, I brought a second ASA with CSC, which prior to this was their main ASA running 8.2 code and did not have issues, of course HTTPS did not filter through it either. the exact same thing happened on this ASA. So apparently it is not hardware related. One other thing I found, if I bypass https, it still happens, and the only solution is to shut down the CSC module. Now I think it may be the ASA policy that while not the cause, but is being difficult. I found that if you pull SIP inspections out, and reapply them in testing voice issues, you must reboot the ASA for them to work again. I am wondering if this is the case with the HTTPS traffic not releasing from the CSC even with the ACL having it removed. I need to try that next.

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?
