Cisco Firewall :: ASA5505 Call Quality Is Very Poor
Nov 3, 2011
I have a client using a VOIP service to a third party provider (RingCentral). They are connected via Cable ISP (6mb) to the Internet and now experiencing performance issues with their VOIP service. They indicated that the call can be heard but that there is jitter and choppines in the call and they have to place a regular landline call. Their provider recommended using QOS to improve. I did not see anything straight forward on the ASDM interface to do this and figure it may require command line to accomplish.
They have Cisco IP 303 and 5252G2 phones which connect through an ASA5505 7.2(4) to their provider for service. Apparently the voip app uses the following ports:
UDP
5060-5090
8000-8200
16384-16482
What would be the best solution to improve performance or perhaps traffic shape / priortize traffic to work. I assume this may be happening if there are heavy downloads or activity happening on the network. The ASA5505 is on 7.2(4). Some coded examples for the above info.
I have a wireless router on the ground floor of my home which is wired to my PC on the 3rd floor. The wifi signal is of poor quality on the 3rd floor. I cannot move the router to a different floor since all of my connections are wired through the home into my networking room (on the ground floor where my router is). I wish to add a media receiver to a different room on the 3rd floor that is not wired already for networking. Streaming video files wirelessly to the media receiver from my router will not work because as stated previously the signal quality is poor on the 3rd floor. My mobo on my computer has ASUS wifi GO. Can I enable the wifi go on the mobo of my PC (located on 3rd floor) to connect to the media receiver (also on the 3rd floor) for streaming? The media receiver will also have an internet browser so will I be able to connect to the internet as well if it is networked to my PC and my PC is connected to my router on the ground floor?
I basically want to keep my PC connected to my main router for high DL speeds and also have my PC networked wirelessly to my media receiver using the on board wifi go. If possible I'd also like to be able to access the internet on the media receiver via the PC.
I recently bought a Bose Soundlink bluetooth speaker and have paired it with both my ipod touch and ThinkPad w500. The iPod Touch sounds great, but the audio coming through the speaker via the w500 sounds like it is clipping, especially at normal-loud listening levels. Both the soundlink and the w500 have the latest bluetooth driver updates installed. The clipping occurs even when the main volume (and iTunes/Spotify) is turned down to 50% power.whether there is a way to reduce the "power" of the bluetooth signal so it does not cause the speaker to distort. Audio played through the speaker via 3.5mm from the w500 sounds great even at high volume.
Currently installed bluetooth drivers:
Bluetooth Enumerator (Microsoft) ThinkPad Bluetooth 2.1 with Enhanced Data Rate (Broadcom) Bluetooth Hands-free Audio (Broadcom) Bluetooth Remote Control (Broadcom)
Do you know if it is possible to filter TOIP flows between call server (Siemens technology) and phones ?Specialy, PIX is able to support dynamic ports opening?? Is there an ALG embeded?Is it required to upgrade PIX or not? is required a special licence??
I got a problem yesterday with a customer that says that the calls from a CISCO IP Phone 7961 to an Alcatel 4018 IP Touch didn't work, well the phone rings but there's no voice; I manage a CISCO ASA version 8.2(1) and I was checking the Inspection Rules in the Service Policy Rules section and when you open the inspection_default at the Rule Actions tab I find that the H.323 H.225 and H.323 RAS box wasn't checked so I ask to the customer to made a test and the same problem happen so I checked both box and again ask to the customer for a test and it works.
I was talking to a partner and he said that maybe this Inspect fix some signaling parameters of this protocol that can't work fine behind of a firewall.
my client wants to make videoconference call thorugh Microsoft Office Communicator, this should be operating between host from one site to another one, but we already configured some rules in the firewalls, and making some test I see that the videoconference use dynamic ports (1024 to 65535) and if we let to operate the videoconference we should remove all the rules in the firewall and that's not the point.
We use MS RRAS services behind a Cisco ASA 5520. In testing the performance I have found that we can only get a little over 2MB of througput when connected to the VPN server over a broadband connection. I have verified that the issue is not the RRAS server itself as I can connect to VPN from the LAN and the througput tests at 300-400MB. I also connected to the LAN directly on the outside of the firewall and only get 4 or 5 MB from there which does not seem right. None of the switches are showing any errors. I believe that I have the passthrough stuff setup as I should. I even went through these steps as recommended by Cisco.

I am trying to use the built in feature of Cisco ASA 5510 smart call home feature with the purpose of automatic backup creation by email. I found the configuration [URL]. I already configured the said instructions but when I send a test email it says it cannot contact the email server. Below is the error that I am getting from our ASA. I am new to firewall.
OGI-MNL-ASA-FW0# call-home test profile ASA_Config_Backup INFO: Sending test message to fcaccam@example.com... ERROR: Connecting to SMTP server xxx.xx.xxx.xx failed: CONNECT_FAILED(33) ERROR: Failed: CONNECT_FAILED(33)
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.

i have asa 5505 with the asdm v5.2 (4), and the asa v7.2(4). This platform has a base license. if i upgrade adsm and asa on v6.2(1) and v8.2(2) if I lose my license and that you need to activate them? i configured site to site vpn (this firewall and the another) that i lose my configuration if i upgrade my firewall.
I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.
Internet ISP -> Juniper SRX 210 Ge-0/0/0 Juniper fe0/0/2 -> Cisco ASA 5505 Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (8.8.8.8).
Issue:
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30) 2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA. 2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop. 3. Allowed all services in untrust zone in bound traffic in Juniper SRX. 4. Viewed the logs when I was trying the ping 8.8.8.8 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (63.223.117.170).
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic. I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did. That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below. However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

there is a line set with a provider with EoMPLS.This is an international line coming with 10M connectivity.the line is working fine with udp traffic but with tcp we don t get any use more than 1M.
I am trying to figure out how to setup quality of service on my network. At the moment i have computers connected to the PC port of my IP phone and the IP phone connected to the switch.I want the PC to stay on the default native VLAN and the phone to go on the VLAN 10I am using SNOM300 and SNOM360. I will configure the on the phone the VLAN ID and the priority.From my research, there are two ways that I can go about this on the port that is connected to the phone I canswitchport voice vlan vlan-idorswitchport voice vlan dot1pand then I will have to execute the commandmls qos trust cosmy question is which command do i use to configure the ports, and am I on the right track? Also, this is how I configure the ports that the IP phones are connected to, how do I configure the port that my Asterisk PBX server is connected to?
We are having issues transferring a 200GB VHD file across our point to point without being corrupted in the process. Any good application for testing the line quality across the point to point?Preferably we want something free, but if there is an in depth tool that costs money, we are open to that option as well.
I took my router with me to visit family at Christmas. It wouldn't allow the wired computer through the switch, but yet I could talk to the router with my laptop. Rather than reconfigure, I bundled up my router & laptop and let well enough alone.Now that they're all back at my house, I can't reliably get the laptop to connect - Low Wireless Signal error. I've reset the modem & router repeatedly. Tried Channels 1,6, 11 and 8&9 too. n only, as that's my laptop's. On 2 occasions it has connected, rebooted and auto connected and run for 4-5 hours. Then it's gone. I've beat this mess for 3-8 hours per day, for days...!!!Laptop(Vista) connects to every other wifi I've tried. It's sitting 4 ft from the router.

Is it possible to use IP "aliases" on an ASA5505 to use as static NAT public IPs to private IPs? For example, I have int e0/0 connected to my ISP using a /30 subnet and I have my private LAN connected to e0/1 with a /24 subnet. At the moment I can use the one usable IP from the /30 to NAT to the private LAN. The ISP is also routing a /28 subnet to the one public IP of the ASA. I would like to use some of the /28 IPs for NAT also. Can it be as easy as just adding the NAT commands? I figure I would have to add that subnet to the ASA somehow, no? In other devices (including the SA520) they use a concept called IP aliases whereby you define what additional IPs the device can use in its NAT config. Does the ASA support aliases? Maybe I have to do something with VLANs?
I have 1 network that I'm trying to make secure, and it needs to access 2 seperate networks. I tried using an ASA5505 that I had on the shelf to accomplish this but discovered that I had the basic license and that was prohibiting me from getting my connection to my 3rd network. I scrapped that idea and grabbed an old pix 501 off the shelf to bring my connectivity to my 3rd network online since the 3rd network is only passing ip traffic to a small group of servers on the outside I figure the 501 should be just fine.
So, here's the problem I am running into:My internal network is 10.10.16.0/16, I have a new domain controller with DHCP on it handing out addresses in the 10.10.16.0/24 range.External Network 1 is 192.168.16.0/24. The services I need from that network are primarily in 192.168.0.0 range, however there is a comcast router 75.123.123.123 (Changed of course) that provides high speed internet I need for my www traffic.External Network 2 is 10.1.1.0/16 I have about 4 servers I need to access on this network and that's it. This network has it's own domain and DHCP controller and I've been given a range of ip's to use on this network of 10.1.3.180-10.1.3.189 My switch is just a plane jane 3com switch with minimal management so I am attempting to use my ASA5505 to handle my layer 3 routing.
So here's my issue:ASA5505 (IN:10.10.16.1, OUT: 192.168.16.6): Passes traffic to External Network 1 and to the comcast router, no problem. All my computers on my 10.10.16.0/16 network have access to everything on 192.168.0.0/24 as well as getting full name resolution and www traffic across the comcast router. Can NOT access 10.1.1.0/16 no matter what. From inside the ASA or from on the inside LAN ports. It CAN ping the PIX 501 PIX 501 (IN:10.10.16.3, OUT: 10.1.3.180) Can ping EVERYTHING. Can ping 192.168.0.0/24, can ping 10.10.16.0/16 and can ping 10.1.1.0/16. Set to globally assign the other IP's in my range as addresses for outgoing traffic.Workstations (IN: 10.10.16.XXX DHCP, using 10.10.16.1 as gateway) Can only access everything on External Network 1. ZERO access to External Network 2. ATM I have both INSIDE and OUTSIDE ACL's wide open for both firewalls just to get connectivity going. I will be tightening it up after it is operational.Attached find a log file (Sensetive data removed of course) that contains the sh run and sh ver for both the ASA5505 and the PIX 501.
I just got an ASA 5505 with Cisco Adaptive Security Appliance Software Version 8.0(4) alredy loaded on it. Should I update/upgrade it to the newest IOS release, or is the 8.0(4) good and stable?
I've been trying to get my WRVS4400N connected to my ASA5505 on the internet through a Cox connection, but it isn't working. I cannot get the ASA to be the DHCP server for the wireless router. I've configured the wireless router as a gateway and pointed the DHCP server to the ASA but no addresses are being passed through to the wireless router. I've included a copy of my config.
We are trying to utilize a 5 ip block of addresses provided by our ISP. What we have assigned from them is like this: 10.10.10.46 - 10.10.10.50 is our ip range. 10.10.10.45 is the gateway. Subnet is 255.255.255.248. If we assign 10.10.10.46 to the outside interface how do we accept inbound traffic from the other addresses?
I have Vlan 100 (inside) and Vlan 65 (Outside)I'm trying to configure RDP and ping traffic from Vlan 100 to Vlan 65 One way.If I connect 2 PCs on E0/0 and E0/1 they can happily ping the their own VLAN ip add 192.168.100.3 and 172.16.65.1I've copied my config,
I have a asa 5505 Sec plus with 3vlan, inside, outside and dmz.
On the outside i have 5 ip's for my use, and in the dmz i have a webserver that need to communicate with one sql server on the inside.
The "sql" also needs to be accessible from outside and thus has a static nat with a dynamic nat so it replies from same ip as on nat ie 72.72.72.5 webserver is natted with 72.72.72.6
sql inside ip is 192.168.1.2, gw 192.168.1.1 webserver ip is 192.168.2.100 gw 192.168.2.1 sec lvl on inside is 100 and on dmz 50
with a dynamic policy running inside-net/24 to dmz-network/24 translagt to dmz 192.168.2.2 i can get it to ping 1 way from inside to dmz, but not the other way around...
All i need is to open 1 port ie 6677 both ways for this communication to work.
I'm not very familiar with the CLI and do most stuf in GUI (know i should learn CLI, but time doesnt let me)...
on access rules i have just added everything from any to any using , ip, icmp, tcp and udp just to be sure... :-)
I want to make it so if a user tries to use a different DNS server the request will be redirected to the one they should be using.I thought this might work but the ASA doesn't do PB routing
ip access-list extended transparent_dns permit udp any any eq 53 route-map redirect_dns permit 10 match ip address transparent_dns set ip next-hop ip.of.your.server route-map redirect_dns permit 20
[code]....
The DNS server is windows 2003?Would policy based NAT or WCCP work for this? If so how would I go about it?
I would like to use an ASA5505 as a simple LAN-to-LAN ethernet router. My plan is to configure two interfaces with the same security level and then use the command that allows interfaces with the same security level to communicate with each other. I can get this to work without having to setup and ACLs or NAT stuff.
for the purpose of a redundency, incase the primary ISP goes down the backup kicks in.Can this be done with the basic license (max 3 vlans) or you need to have the security plus license. (20 vlans) Currently not using the 3rd vlan (dmz)
setting up ASA to allow passive FTP connection! I can get the FTP client to connect but it does not pull the directories. I have opened 21 and range of 55536-55566. I had some trouble gettting the range opened and saved. Normally with other small business routers (GUI) I make sure those ports are forwarded and ftp works.
Is the ftp inspection killing connection or is it my config?
Do some have some realistic performance numbers for a ASA 5505 on a mixed setup with local internet breakout and site to site vpn ( and don't tell me 150 mbps 3des throughput on a 100 mbps ethernet) - what can be expected in a live environment where we f.ex feed it with a 100 mbps internet connection - with a site to site vpn with f.ex 20 office workers running office on a remote terminalserver and mixed local internet breakout.
