I have installed a new ASA5510 with CSC, and everything is working properly except the access to websites using https. All sites/access to them seem to be blocked by the ASA. I have read that this access is by default enabled and I have tried to add configuration to allow https access to the firewall but without success. [code]

View 9 Replies View RelatedI am having trouble with our ASA5510. After upgrading the internal memory from 256 MB to 1 GB and upgrading the firmware to 8.4.2 we are experiencing that the ASA is running out of 1550 byte blocks. When that happens it is not possible to connect to the ASA by ADSM or SSH and new VPN IPSEC tunnels are not coming up. The only way I know how to fix this is to reload the ASA. This is happening every 2 to 3 days.
In the free blocks graph one can see that there is a loss of about 20 blocks per 10 minutes.
My company has a peer to peer network of 10 personal computers without a server. Operating systems from Windows XP to Vista. I've recently installed a Cisco RV120W Wireless-N VPN Firewall. It's configured in DHCP Server Mode with printers/copiers that have static IPs below the DHCP range.
I'm having a problem with certain stations being used for personal networking, shopping, etc. during business hours. Consequently I would like to limit internet access on these stations. However, some internet access is required because of online database software that's an integral part of our business. I've been reading in the Administration Guide about URL Blocking. Would it be possible to give static IPs to certain stations and then limit their internet access to 1 or 2 specific websites?
FYI, I've read about the Trusted Domains and Blocked Keywords but cannot quite understand how to parley this into the solution I need.
I am running a Cisco ASA 5510 with Trend Micro Interscan. We have it set up to filter https except for a handful of sites. It is filtering the ones we don't want ie: facebook, and youtube. Though it is causing all other https to slow to a crawl. Therefore some sites it times out on us. What should we be looking for to change so it isn't slowing the allowed sites down?
Version numbers
ASA - 8.4(3)
ASDM - 6.4(3)
Trend - 6.6.1125
Running ASA 5510 with code 8.3 in it.We have our few https portal and OWA websites in HO.We access these sites from the network behind the ASA.All works perfectly fine.
In order to have control on internal network traffic we placed a web-filtering device (Fortigate) in transparent mode.To start with of we haven't blocked anything via new box but https portal and OWA stopped working from certain computers.At the same time other https sites were reachable from the same computer/s.We checked that website was tracable using traceroute from ASA,Fortigate and even from interal computer(from the one which it is not opening).This behaviour is random.
My company uses a pair of 5510 ASAs as the gateway to Internet. I once configured policy-map to filter certain webpages (facebook, twitter, ...etc) and they work fine. However nowdays those websites all support HTTPS. In the https the URL seems encrypted so can't do regex match... Is there anyway that I can still block those webpages?
Another two ways I can think of are
1. Block IPs (don't really want do this unless absolutely necessary)
2. Block DNS for the URL (however they can work around by setting static DNS entries)
How to block a single website, but I want to do the opposite. I would like to block all website except for a handful of them. Any example configs?

can't access gmail or any https sites at all such as fnb.co.za or auction sites ect... I've tried resetting my rooter, configured all the settings as they were when working, I have basically gone into my network & sharing centre and change adapter settings to make sure all the settings there are as should be, reset , & config all of those as well, I've also gone into cmd and reset my D-link completelly from the command, and also tried to restore my computer to an earlier stage which did not work either , Now all I can gather is that It has to be a block some where most likely with the rooter , which is blocking access to port 443.

View 2 Replies View Relatedthe set-up is: a DSL modem in half bridge (it does all the PPPoE connection) passes our static IP (55.167.x.x) to the ASA's outside interface ... (the modem has an IP of 192.168.1.1, but not sure this matters)
then I have one inside interface on 192.168.43.1, which connects to a server and we have a working site-to-site VPN between this server and a client.. so I know most of it's set up right ... nothing else is on the 192.168.43.0/24 network.
the management interface is on 200.200.1.0/24 so it's out of the way and incidentally connected to a dedicated PC, which also has console access via the blue serial cable.
the last interface Main_Network is on the 192.168.0.0/24 network and it's this that I'm trying to get to work... at the moment I just have one Windows PC connected directly (does it need to go through a switch?) into the ASA for testing with a static IP (192.168.0.72), but I can't ping anything outside from the PC... only the ASA's interface (at 192.168.0.30).. I have the gateway on the PC set as 192.168.0.30 by the way.
The ASA can ping all the inside machines and anything I like outside.
Here's my config ... the static routes are there for when this replaces the current modem/router and the whole network plugs into the ASA.

Should i configure some acl? I read that all traffic from an interface with a superior security level to other interface is allowed, so since my inside interface has a security level of 100 and the outside 0, it should be possible access to internet from an inside computer?!
From all configurations and examples i have seen around, they all contemplate a fixed IP address from the ISP, but in my scenário i have a dynamic one. This fact matter for the configuration i want to do?

View 2 Replies View RelatedWe have an ASA5505 UL bundel, updated with this license "L-ASA5505-SEC-PL=" to enable traffic from DMZ to Inside. No NAT or rules deployed for that yet.
On the Inside we have Exchange 2007 in a single server installation. The public url for smtp, ActiveSync, OWA and Outlook Anywhere is mail.company.se. There is a static NAT for outside traffic to access above mentioned services on inside. Now, on DMZ there is the WLAN for guests to access the Internet. How ever, our Smart Phones with WLAN turned on, cannot sync to the Exchange Server on the Inside! The DMZ gets IP-addressen from ASA on DMZ Interface with external DNS configured. How can I configure the ASA to achieve the function of ActiveSync from DMZ to Inside with the public URL from the phones?
I have a closed network that is not connnected to the internet, just other sites that we want to communicate with. We have a cisco router connected to the outside interface on an ASA5505 and a cisco router connected to the inside interface on the same ASA5505. I have an inside interface that connects our management LAN, five separate DMZ interfaces with a separate LAN (VLAN) on each DMZ interface and the outside interface that connects to the other sites. Data is not allowed to mingle between the five DMZ's.
Alll connections to the other separate nodes are handled with the router on the external interface. IPSEC GRE tunnels have been established between all sites and BGP routing has been verified. Pings are good between inside, dmz and external interfaces and between the DMZ's and the other sites, to include hosts on our local networks and hosts at the remote sites. Inter and intra traffic is enabled.
When a remote site attempts an https connection, the initial ACK handshake makes it through the ASA5505, but the return SYN/ACK is being knocked down and I don't understand why (it is not because of ACL's, they are any any at this point).
Why the return SYN/ACK to the remote site isn't getting through the ASA5505 outbound. Will probably have the same issue with FTP, but right now, just trying to solve one problem at a time.
ASA5505 is in routed mode, not looking to NAT since the IP addresses in the DMZ need to be reached by their real IP address.
I have a PIX 501 with 6.2 FW. The firewall inside network is connected to a Windows server (Mailserver). I can get access to most websites on all clients as well as on the server. However, there are some particular websites, such as facebook.com that the server and all but one client cannot access. I get a "cannot display the webpage" in internet explorer.
I have disabled the Windows firewall and AV. I have also scanned for any malware and no malware was found.
I found on the forums a "fixup protocol dns" solution, but my PIX version does not support it.

We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN). We bought the block of 16 IPs (in a different subnet) which is routed through the main router (69.x.x.x)and configured the outside interface of ASA with a public IP 64.x.x.x and subnet mask 255.255.255.240. Below is the network structure.
But, we can't access the ASA by it's public IP.
DSL Modem → RV082 router → Switch → LAN
(69.x.x.x) ↑ (192.168.0.0)
Cisco ASA 5510
(outside: 64.x.x.x, inside: 192.168.0.172)
I have a subnet for guest network access, both wired and wireless. We have a Netgear ProSafe that is trunked to a Cisco 2901 performing 'Router-on-a-Stick'. For most internal traffic, it all stays behind the ASA. But for guest traffic, I have a route-map that sets the next-hop address as the outside interface of the ASA. The question is, how can I still permit those users to access our internal DNS servers? Do I need any particular NAT translations, exemptions, DNS doctoring, hairpinning, etc.? I have an ACL on the inside interface that permits traffic from the guest networks to our internal DNS servers, and then the next ACL line denies any other traffic from the guest networks to any of our internal networks.
