Cisco Firewall :: To Enable Access To Use RealVNC On ASA 5505

Feb 27, 2011

I am trying to enable access to use RealVNC on our Cisco ASA 5505 without using VPN. RealVNC uses port 5900. Users should be able to vnc to 99.23.119.78 and reach our internal server 192.168.1.4. So far they are receiving connection refused.

We recently purchases the Cisco ASA 5505 to get familiar with it, possibly buying more appliances for our branch offices. However, since the appliance is installed, our SIP telephones no longer register with our SIP service provider.
 
The SIP phones are all on 10.0.1.0/24 while the SIP provider is external via the outside network. I copied our configuration below. how to enable SIP for all 10.0.1.0/24 hosts and ports 5060, 5160, 5260, 5360?

Cisco Firewall :: Can't Access ASA 5505 Via SSH

Apr 23, 2010

I can't access our ASA 5505 via SSH from the outside. I've configured this through the ASDM to allow SSH (Device Management > Management Access > ASDM/HTTPS/Telnet/SSH). I added a rule that allows SSH on the outside interface from 0.0.0.0 0.0.0.0. When I try to ssh in with putty, it says "server unexpectedly closed network connection" When I watch the logs on the ASA, it shows a Built inbound TCP connection on port 22, but then immediately a Teardown TCP connection. It doesn't show it's being blocked by any rule. Is there something I'm missing on enabling SSH?

Cisco Firewall :: Access From Outside Of 5505?

Mar 8, 2013

I have a web server behind my 5505 that I'd like to access from the outside of the 5505 (still within my home network though). Its running on port 3000. I made the changes but I have been unable to access my server from the outside.

I do have an Airport Extreme in from of the 5505 and the 5505 is getting its address via dhcp from the airport. So I'm trying to hit 192.168.2.57:3000 from my wireless airport network.

Cisco Firewall :: ASA 5505 / Can't Access Web Server

Jul 9, 2012

We have a Cisco ASA 5505. As of yesterday we could no longer access our web server (the web server is hosted off-site). Pinging the DNS address and direct IP (from the firewall and a PC) both return no response. Pinging the IP from the T1 router responds properly, meaning the router can access the web server, but the firewall cannot. Accessing the web server has never been a problem, and no configuration changes have been made to the network/firewall. Other locations can access the web server just fine.

Cisco Firewall :: ASA 5505 - Having No Access To Webpages?

May 3, 2013

I'm currently facing a problem with a ASA5505. I've set it up from factory defaults... From the CLI, I can ping an the outside interface, the GW and an outside IP (ex:8.8.8.8).So I believe that there's no connectivity issue and the configuration is correct.
 
However, for a reason that I don't know, users can't have access to web pages.The product license allow me to have 50 host connected. Currently I've only got one host connected...
 
When I enable syslog, I can see the following messages :Deny traffic for protocol 17 src inside: 192.168.1.20/64429 dot ouside:8.8.4.4/53, licensed host limit of 0 exceeded.Where this limitation can come from ?

Cisco Firewall :: Remote Management Access Through VPN On ASA 5505

May 21, 2012

I have a remote ASA5505 running 8.4(3) with a working site 2 site VPN tunnel to my main office. (The main office is running an ASA 5510 with OS 8.4.3 as well). The encryption domain is all private IP on main site vs. 172.16.10.0/23 on remote site.
 
Relevant config of the remote ASA:
 
interface Vlan1
nameif inside
security-level 100

[Code].....
 
I can manage the ASA on the outside interface (outside of the site 2 site VPN) using the TACACS credentials I can also ping my management station from the ASA using the inside interface, but as stated, the other way around does not work. I have not yet tested if management from the local 172.16.10.0/23 subnet works, but I will try this next.

Cisco Firewall :: Restrict Internet Access With ASA 5505?

Jul 5, 2011

I would like to restrict Internet traffic (HTTP & HTTPS) for Inside Users with an ASA 5505. I would like to setup a proxy-like system where a User/Password must be entered before the User can actually browse the web.
 
I know that this can be done with an additional RADIUS/TACACS+ Server. Is this also possible without any external AAA Server, so with User/PW stored on the ASA locally only?

Cisco Firewall :: ASA 5505 InterVLan ADSM / SSH Access

Jun 29, 2012

I am running into a issue that I cannot seem to figure out. I have a asa 5505 with the Security Plus license. I setup a native vlan where all of my network devices sit on. ie my Wireless Access point has an ip of 192.168.3.2, my switch .3. I have no issues managing these devices from any vlan I am on (permitting firewall access rules). When I try to access my ASA via ASDM/SSH. I have to use the gateway of the vlan I am on. For instance. If I am on vlan 10 I have to use 192.168.10.1 for access, if I am on vlan 20 I type 20.1...etc...etc If I type in 192.168.3.1 I get an error in the ASDM logs that states TCP reset by appliance. This is for any gateway I type except for the gateway of the vlan that I am connected to. I am posting a sanitized config. How can I configure the ASA to permit access via any gateway.

Cisco Firewall :: Can't Access Internal Servers From Behind ASA 5505

Apr 3, 2013

I am having some trouble accessing some backup Email (Outlook Web Access) and Citrix servers located behind an ASA 5505 firewall at a remote datacentre. Simply put, when I go to the specific URL (e.g. [URL]) I do not arrive at the splash page, I just get a message saying that the server took too long to respond in the web browser. I'm wondering whether I have missed something on the configuration or the firewall itself is not letting my requests through. The remote servers are located at a remote Disaster Recovery site and use the subnet 192.168.4.0/24. I am at head office which is connected to the DR site via a VPN using 192.168.1.0/24.

Cisco Firewall :: ASA 5505 Static Hosts Cannot Access Outside

Feb 9, 2013

I have configured the ASA in a very similar manner to how the PIX was set up but I'm having trouble with some hosts on the inside accessing the Internet. Any inside hosts which use DHCP work fine. Any inside hosts with a static IP (and configured on the ASA with a "static" rule) cannot access the Internet. For example, in the config below the server daviker-dialler cannot access the Internet. I've spent a few days working on this now and have started from scratch several times but I'm not getting anywhere. Apologies for all the X's everywhere, didn't like to post anything sensitive on the Internet.
