Cisco Firewall :: Users Behind ASA5505 Firewall Are Unable To Access Internet

Feb 24, 2011

I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.

When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.

The ASA5505 configuration is shown below.

hostname Firewall

interface Ethernet0/0
description Connected To Internet Router
switchport access vlan 10

Cisco Firewall :: 5505 - Users Unable To Access External Email Servers ASA?

Nov 28, 2011

I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using  ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA.  I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!

Cisco Firewall :: Unable To Access Inside Resources From Outside On ASA 5510

May 19, 2011

I have recently deployed a Cisco ASA 5510 Security plus firewall on my companies network, but there is a problem that I am finding hard to get by and I think it is ASA related.
From (inside we are not able to hit any of our sites that are on the (outside).  I have nat policies in place to translate the public to private, but I think I that I need some thing more.  This seems to be occuring mainly with our external web sites as well as another animoly with regards to FTP (but it may be fixed if the http issue is resolved.)
I was hoping some with a lot more knowledge on ASA firewalls than my self can spot the error in my run-cfgs.

Cisco VPN :: ASA 5510 - AnyConnect Users Unable To Access Remote Subnet

Jun 9, 2013

I have a weird problem which I have already submitted a TAC ticket about. When users authenticate through AnyConnect into our HQ ASA 5510 they grab an address from 172.16.254.x. What we have been noticing intermittently is that when logged into our network through the client they are unable to access their resources at one of our remote offices which is connected over l2l to the HQ ASA. This problem just started randomly a week ago and we have been working with Cisco trying to create a solution.
My quick fix is logging into a device at the remote office which is trying to be accessed and pinging the gateway of the virtual subnet for AnyConnect users. When I ping it goes through after a few dropped icmp packets and then the issue is resolved for about 8 hours or so.

Cisco Firewall :: Getting Internet Access On ASA 5510

Feb 27, 2012

the 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, but not sure this matters)
then I have one inside interface on, 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 network.
the management interface is on 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 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 (, but I can't ping anything outside from the PC... only the ASA's interface (at I have the gateway on the PC set as 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.

Cisco Firewall :: ASA 5510 With 8.0.2 - Exchange 2007 Outlook Anywhere / OWA Users

Aug 15, 2011

We have a ASA 5510 which was running 8.0.2, we recently upgraded it to 8.2.5 and since the upgrade remote users for exchange 2007 are not able to download any large email attachments(over or close to 1MB). This is only happening to Outlook anywhere users or OWA users who are connecting to the exchange server using https(443) externally. If the same users connects internally they do not face any issue. When i check the logs on ASA i am gettings lots of RESET-O and RESET-I entries. Looks like the connection between the client and the server gets reset.

Cisco Firewall :: Configure Internet Access - ASA 5510

Dec 9, 2012

I have to configure a default-factory firewall (ASA 5510) in a simple scenário like this image represents:At this moment i have configured the interfaces as represented above and at this moment what i want is grant access from a LAN computer ( to the internet.
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?

My firewall is running the software version 8.2(5).

We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN).

Cisco Firewall :: 2901 / ASA 5510 Guest Internet Access?

Jan 15, 2012

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.
