Cisco Firewall :: ASA-5520 - Cannot Hear Outgoing Message
Dec 9, 2009We have setup the IP phone proxy on our ASA-5520, we had a couple of issues with the initial setup, but nothing major. It has been up and running for a few weeks and basically everything works perfectly just like we designed it except for 1 strange audio issue on outbound calls. We can make a call to anywhere, no problem, if the call is answered, no problem, perfect call setup and good quality 2 way audio. But if the person we called doesn't answer the call and that call goes to their voicemail we loose all audio from that point forward, we do not hear their outgoing message or get any prompts just dead air. The same situation appears to be true for any "recorded" service on the other end of the call.

Oct 30, 2011Here's the current scenario:
[LAN] <---> ASA 5520 <---> Cisco 2911 <---> [Internet] <---> Server A
|
|
[DMZ]
Whenever I access a website running in "server A" (only HTTP traffic) everything works fine. The problem is that when I try to access a different service on the same server but listening on port 2000/tcp I get the TCP Reset-O message on the ASA and the workstation's browser says that "Internet Explorer cannot display the webpage".
A weird thing: if I access this service from a machine on the DMZ, it works fine. From the LAN (Inside) it does not work. The main difference is that from the LAN to OUTSIDE the ASA does NAT. From the DMZ to OUTSIDE it's just routed. I did another test from the LAN and the captured traffic is attached. I've been messing around with protocol inspects and firewall + NAT rules on the ASA but no luck at all.
Cisco Firewall :: 5520 - Error Message When Trying To Access ASA (8.0(3)) With Asdm
Aug 26, 2012When trying to access the asa (8.0(3)) with asdm the console send follwing error message:
vPif_isVpifNumValid: pifNum out of range!
vPif_getVpif: bad vPifNum(0xa6) from 87EBC81 from 83833B4
Have a strong suspicion that it is a hardware failure (since asdm has worked and have tried to restart the box) can not see any errors with any show commands, but could it be a RAM error .

View 1 Replies View RelatedCisco Firewall :: Changing Syslog Message 106100 Severity Level?
Mar 5, 2012I'm fine tuning some of our ASA logging config, and am having an issue with one particular syslog ID.The message is: syslog 106100: default-level informational (enabled)and the log settings are:
Syslog logging: enabled
Facility: 20
Timestamp logging: enabled
Standby logging: disabled
Debug-trace logging: disabled
[code]....
This ACE log entry is generated by explicit deny any any statements at the end of all the ACLs, e.g.access-list inside_access_in extended deny ip any any log interval 600 Based on the config, I would expect to see this being logged to the syslog server, but not to the local buffer, but am still seeing them locally in the buffer:
Feb 22 2012 10:58:20: %ASA-4-106100: access-list inside_access_in denied udp INSIDE/HOSTABC(52629) -> OUTSIDE/HOSTXXX(162) hit-cnt 5 300-second interval [0x3baecf1e, 0x0]
It also still shows these as level "warning", %ASA-4-106100, instead of the default %ASA-6-106100 I've tried removing and re-applying the config at different levels but it still reports in the buffer log as level "warning", %ASA-4-106100 This also doesnt affect every 106100 log that is generated. Most messages are generated at the correct level 6 severity but some seem to randomly log at level 4. There doesn't seem to be any pattern to this. The same access-list line can produce severity level 4 and 6 106100 messages.
Cisco Firewall :: Error Message When Failover From Standby To Active In ASA5585

Cisco Firewall :: 5510 Inspect SIP Dropping Request Message Packets
Mar 17, 2011I have 2 ASA 5510 firewalls at 2 different sites. Both running on version 8.0.4. Users are using an Instant Messaging type of application provided by a local telco here which is able to send and receive SMS using SIP (from the packet capture that I've done).
When users use the IM in site A, they are able to send and receive text messages via the IM from behind the firewall. However, when the users are in site B, users are able to send out text messages but not able to receive them.
I noticed that when I remove "inspect sip" from site-B's global policy map, users from site-B can successfully receive text messages. I have confirmed that it is the firewall that drops the packets as I have captured the inside and outside interfaces of site-B's ASA and I can see the incoming sip "request: MESSAGE" packet on the outside interface but I do not see the packet exiting the inside interface.
I have cross check both firewall configurations, and I do not see anything suspicious commands relating to sip that might cause this issue. Is there any command to troubleshoot why the sip inspection is dropping the sip packets on site-B?
Cisco Firewall :: Upgrade From 5505 To 5520 On Network - ASA Firewall Throughput
Feb 27, 2013I'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.

View 1 Replies View RelatedCisco Firewall :: 5520 Identity Based Firewall Doesn't Work Using Citric Published
Jul 26, 2012We are using the newest release of AD Agent (1.0.0.32.1, built 598). The ASA Firewalls 5520 are having the software release 8.4(3)8 installed.When somebody tries to connect thru the Identity based firewalls from a citrix published desktop environment (PDI) the connection is not possible. Checking the ip-of-user mapping on the firewalls (show user-identity ip-of-user USERNAME) mostly doesn't show the mapping of the USERNAME and the PDI the user is logged in. The user-of-ip mapping of the PDIs IP-address shows mostly other users, which then are used to authenticate the acces thru the firewalls.
What is interesting, that on the AD Agent using "adacfg.exe cache list | find /i "USERNAME"" i can't see the PDIs IP-address neither because it is mapped to another user.Is Citrix Published Desktop environment supported to connect thru Identity based Firewalls? How AD Agent, Domain Controllers and Firewalls are working together? On the firewalls with "show user-identity ad-agent we see, the following:
-Authentication Port: udp/1645
-Accounting Port: udp/1646
-ASA Listening Port: udp/3799
Why Cisco does use 1645 and 1646 and not 1812 and 1813?The Listening Port is used for what purpose? we tried the AD Agent modes full- download and on-demand with the same effect.

Currently there is a rule in place to allow an incoming connection on port 2222 from a specific ip address to allow access to a web app our developers created. This is a test before the web app is released live. Now the web app can communicate with the specific address and port but the incoming connection on port 2222 isn't getting through. Everything looks great in the firewall but how can I log any hits this ACL takes to identify any potential problems?

Cisco Firewall :: 5510 - Display User Message When User Connects Using AnyConnect Client?
Apr 20, 2009We are using an ASA 5510 and remote access (SSL VPN) using the AnyConnect client.
Is it possible to display a user message when a user connects using the AnyConnect client, matching a specific dynamic access policy? Can the message be displayed when the action is "Continue" rather than "Terminate"? I can't seem to get this to work and wondered if there was a LUA function to do this.
We have a DAP which gives a restricted ACL when the user's anti-virus is out of date, and I wanted to notify the user to update their anti-virus and reconnect.
