I am having an ASA5510 with a CSC-SSM-10 module. I am able to block http traffic through the ASA but cannot block https traffic through it. Need to block https traffic using the CSC module.

View 1 Replies View RelatedOne of our customers has an ASA5510 with CSC SSM-10 security module. The software version of the module is 6.6.1125.0.Is it possible to do https filtering with this module ? The customer is complaining that this is not possible...from Cisco I've read the following:
• HTTPS Filtering
– Able to allow or block HTTPS traffic.
– Supports group-based and user-based HTTPS policies.
– Includes URL blocking/URL exception list support for HTTPS domains.
How to filter URL which includes "https", using the csc ssm module?

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?
My web server is out of public IPs. I requested more from my ISP and I got a different range with a different gateway. How do I handle the configuration on my Cisco ASA? Without any configuration changes to the firewall I saw the traffic hitting it and being blocked. I added an access rule to allow the traffic. I added a virtual interface on the ASA. I added a virtual interface on the web server. Using "Packet Tracer" the traffic flows from the outside interface to the new virtual interface. But I'm unable to access my web server and I don't see any traffic on that IP reaching the web server.Using Cisco ASA 5510.

The DMZ works fine with WiFi on it, but user's iPhones can't get email unless they turn WiFi off.Is there a simple way to allow HTTPS traffic through the DMZ interface to our internal Exchange server which is NAT'd on the 5505's external IP?
View 3 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 RelatedMy device has 3 interfaces configured: inside, outside, DMZ. Right now I can access the DMZ from the Internet and I can access the DMZ from the LAN using an exempt nat statement. I am having a few issues setting up DMZ > LAN access however. The servers running on the DMZ need to send information to my LAN such as syslog traffic for example. Will DMZ traffic be NATed or should this somehow be excluded? Bascially all LAN devices should get to the DMZ devices by their actual IP and vice versa. Are there any special statements I need to add to the ASA such as nat or ACLs to make this work? My LAN is 10.10.6.0/24 and DMZ is 192.168.254.0/24.

View 1 Replies View RelatedI have an ASA5510 with 8.3 and a Cisco PIX525 (retiring). The ASA was for VPN traffic only while the PIX was for all other Internet traffic. I'm trying to move all the traffic to the ASA5510 so I used the PIX to ASA migration tool. I migrated the PIX rules over to the ASA5510, however we can't receive email and there is no external access to our internal websites. But the VPN connections remain intact and internal users can get out to the internet.
When I run Packet Tracer on my outside (incoming rules) the packets are dropped at the inside interface. What am I missing?
How does a firewall block or filter traffic on a specific port or IP address?

View 1 Replies View RelatedI've been trying to figure this one out for quite a while. I currently have 2 inside interfaces (data, phone) and I am moving to 3 inside interfaces (servers, workstations, phones). I have not been able to get any traffic between the interfaces. With the current setup it was not a major problem. With the new setup it will be a major problem.
Below is a sanitized version of the config.

Up until recently one of my sites was able to get to a postilion subnet. Then we started receiving "host unreachable" e-mails. Posting told us SMTP traffic was not getting let in. I've compared the current config to a config that was saved before the issue popped up and found really no noticeable difference.
I tried a packet tracer trace with no luck: SiteB- Firewall# packet-tracer input outside tcp 11.2.2.36 12345 65.19.0.0 25.

Attached is a sanitized config. I'm not entirely convinced it's a firewall issue, but I need to some successful testing to prove otherwise.
I have configure Cisco 5505 as layer 2 firewall mode. I have vendor machine connected to Cisco ASA 5505 on port 2 as VLAN2 inside then VLAN1 outside connected to my internal network on layer 2 cisco 2960 switch. This machine needs access only to LOGMEIN then block all internal/internet traffic.

I have an ASA pair configured to replace a router that hosts a collection of IPSec Tunnels. Tunnels appear to work. I am lab'ing some additional controls that I would like to implement. On the Production Router that i plan to replace with the ASA's the current Tunnels are all wide open (all traffic allowed to pass). I was hoping to lock things down a little without having to reconfigure all of the Tunnels. My though was that an ACL on the Inside Interface blocking selected traffic Out (so into the LAN) should not impact the stability of the Tunnels but allow me to restrict some traffic from entering the LAN. One port that I was attempting to block is RDP 3389. When this ACL is applied to the inside interface it does not block Port 3389 at all. What am I missing? Is it that the trffic is being allowed because it is coming through one of my 'open' Tunnels?
Shouldn't IPSec Tunnel traffic be processed by the Inside Interface ACL just like all other traffic?

This work great on a 2821 Router, but not so much on the ASA.
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.
