Cisco Firewall :: ASA 5505 - Create Access Rule To Connect To System Using RDP?

Mar 6, 2012

Just started using our ASA 5505 v8.2 (1) Trying to configure the ASA appliance to allow access into an internal resource (i.e want to be able to RDP into a system behind the ASA from the internet).I have used a static NAT:

static (inside,outside) netmask
 access-list OUTSIDE extended permit tcp any host eq 3389
When I view the logs it is reporting the following:Inbound TCP connection denied from (external IP) to /3389 flags SYN on interface outside.Been pulling my hair out with this one as I believe I have everything configured correctly.

Cisco Firewall :: 5505 Block Port 80 On A Specific Host In LAN

Apr 22, 2012

I'm using an ASA5505 (8.4(1)) and would like to block port 80 on a specific host in the LAN so machines in other remote LANs connected via VPN can't access this port on the host. Devices in the local LAN should have access to this port on the host. Here are the commands I'm using:
-access-list block_port extended deny tcp any host eq 80
-access-list block_port extended permit ip any any
-access-group block_port out interface inside
These commands are not working as I would expect them to. When I browse to from a remote machine over the VPN tunnel I am able to access the host web server.

Cisco AAA/Identity/Nac :: ACS 5.3 Cannot Create Default Network Access Authorization Rule

Jun 10, 2013

when I click 'Create...' under Access Policies > Default Network Access > Authorization, and then press the 'OK' button, it says 'Please configure at least 1 condition.' However I have no way to configure conditions as the 'Conditions' text is just bold text and not a link or any sort of configurable area. If I go to 'Customize' on the bottom right and add conditions to the right list box, I still have no options when I press Create. Also, the 'green light' next to Default Network Access is grey with a line through it. This is the most cryptic system I have ever used

Block Access To Internet On Specific Time Intervals?

Aug 10, 2011

I have the Qwest/Actiontec Q1000 modem/router. I go to the ip address using my web-browser and open up advanced configurations -> access scheduler. I select a computer (and it automatically adds the MAC address) and then the days/times I want the internet to be accessible. However, when I click "add" (to add my internet allowance to the scheduler list) it just says 12:00 to 0:00, which is essentially permanently blocking the internet for that computer.

Cisco WAN :: 1841 To Block Access To A Specific Interface

Feb 11, 2013

I have an 1841 between my firewall and the ISP.  Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network.  I use the inside interface for configs aand snmp access, etc.   Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN.   I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface?  I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.

Cisco Firewall :: Ubuntu 10.04 / Firewall Starts Randomly Responding To ARP Requests For Other IPs

Aug 22, 2011

I have my firewall on IP (for example, real IP is a class C address).  I have a web server (Ubuntu 10.04, though this happened before with an 8.04 box as well) on ip  Everything will be functioning fine, and I won't have any issues for a while.  Then, randomly I'll have problems getting to my web server, getting disconnected from SSH sessions.  I go to one of my linux boxes and do an "arping -b" and I will get  two responses, one from my firewall and one from the box, as illustrated below.  The only way to correct the issue that I've run into is to reload the firewall, which will then behave properly again until it randomly decides to start answering ARP requests on the other IP again.
