Cisco Firewall :: ASA 5505 Timeouts PPPOE?
Mar 1, 2012
I am tyring to remotely diagnose a troublesome ASA5505
It is connecting via PPPOE and the original suscpicion was that the PPPOE was going down during heavy loads during the day, i.e 9am and lunchtime. I suspected MTU and have verified the MTU outside is set to 1492
However further troubleshooting doing a remote ping to the PPPOE address indicates that this does not drop at all.
When remoteley connected to the ASA my session dies and any outbound internet fails, then in a few minutes it comes back.
all the time the PPPOE line stays up?
One thought is that although the line does not go down it is being crippled with traffic and just getting so unresponsive it appears it has died.

We recently got a 10 meg dedicated internet fiber connection installed. I connected it to a PIX 501 firewall and everything worked fine (I tested it for a couple of weeks). A couple of days ago I got a new ASA 5505 and replaced the PIX with this device. It works, but every so often there seems to be a timeout when surfing the web whereby I click on a link and there is up to a 45 second wait and then the page loads quickly. I was not getting this before on the PIX so I'm assuming it's not a latency issue with the connection. I am the only one using this connection on the network so it's not to say that it's being bogged down. I want to roll this out to the other users on the network but not when this is happening. The configuration is below:

Im running 8.3 on a 5505. We've got a few ssh tunnels originating from inside to some place on the internet. It seems these tunnels are closed every n minutes. I've seen two recommendations for altering the timeout values, and what I am interested in is infinite timeout (0) for these SSH tunnels.
Suggestion 1, alter timeout "conn". Default is 30 minutes, but I suspect this might have a negative impact because no inactive connections would be closed, ever. If it however is recommended to alter, how to set it to "0" (off/unlimited)? timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02
Suggestion 2, enable a ssh class map which explicitely set the timeout for the ssh connection. Is this recommended? How would I achieve unlimited time? And what about random-sequence-number disabled as seen below, is that really recommended?
class CLASS_MAP_SSH
set connection random-sequence-number disable
set connection timeout idle 48:00:00 reset
set connection decrement-ttl

We're getting "Connaction Timeout / Connection Failure" error messages several time per day. Here is our setup:
Verizon FiOS Internet (ONT Box) --> Cisco ASA 5505 --> EdgeMarc 4500 Router --> Cisco 300-24G Switch --> Dell PE1950 Servers
From past few months, we keep getting Connection Timeout and Connection Failure error messages in our vendor application which connects to SQL Server 2005. Also Terminal Server 2003 keep disconnecting for every few hours.After several days of troubleshooting, we come to know that this Cisco ASA 5500 is not working properly. When I access the ASDM, it shows several warning messages.I know there is a setting option to configure TimeOut, but is there anyway to test and track the ASA 5500 regarding this Timeout issues?

We currently use a linux software based firewall called IPCop that sits between our network and router (This is in bridged mode) IPCop conects over PPPoE and everything works fine.
However the system is not reliable and I fear not that secure so have purchased an ASA5505 now I have added the PPPoE info to the device using the ADSM software however although it picks up my external static IP I'm unable to access the internet. On IPCop I only had to enter the broadband credentials and it worked however I feel like I may have to add more to the Cisco, for example do I have to specify DNS servers and do I have to set a static route?
Here is my config file so far (Note I think I have turned on the ability to ping from internal to external). My config I have done through the ADSM as opposed to the CLI
: Saved:ASA Version 8.4(3) !hostname ciscoasaenable password 8Ry2YjIyt7RRXU24 encryptedpasswd 2KFQnbNIdI.2KYOU encryptednames!interface Ethernet0/0switchport access vlan 2!interface Ethernet0/1!interface

configure my ASA 5505. It is setup using PPPoE. What I want to do is this:
I have one of my IP addresses (99.23.119.78) setup for ftp using the ftp protocol to our internal IP address 192.168.1.3. What I need is to also allow for HTTP access but not just that, I need it to forward the http port to port 9000 because the web interface requires port 9000 for customer access. Previously on our old firewall customers were able to access the web interface by browsing to [URL]. I would like to not have to not require the port in the URL.
In addition, I would like to be able to setup a different IP address in our range (99.23.119.73) to be setup for http access using the standard port 80 for the same internal IP address (192.168.1.3). This URL will allow us to access the administration web interface for the FTP server.
Here is my current config:
Result of the command: "show running-config"

I've an ASA 5505 connecting to a vdsl modem. The ASA is doing the PPPoE encapsulation. I've noticed the traffic amount on the outside interface is always twice the bandwidth it receives on its inside interface. I can't believe the PPP encapsulation is taking that much. Only two interfaces (inside and outside)

I got a Problem on a customer which is using a Failover ASA 5510 pair with SSM-CSC-10-K9 modules.The clients have to connect to a webserver where they are doing some calculations.If they prepare everything and want to calculate everything what takes a couple of time the session is after about 3 minutes timedout.My first idea was to set session specific timeouts which are a bit longer then the normal but this setting did not work. I created a policy which did not work for me. How to set connection specific timeout's? [code]

Just recently we replaced our HQ Cisco-Pix with Cisco-ASA 5510. where we have many branches connecting to our HQ through site-to-site vpn.
Since putting this new ASA5510 at HQ , while we are getting a Remote-Desktop session into our branches clients, and at the time when even a single TIMEOUT occurs on the vpn-link so the remote-desktop session gets completly lost. then we have to re-connect the session.
This issue happens as i said above when a single timeout occurs on the vpn link. What is the issue with the ASA5510. because with pix we didnt have this issue, remote-desktops were never geting lost / reset with single timeout

I am using ASA 5505 with firmware 8.2(2). My ISP uses PPPoE as a WAN connection protocol. There is a problem with getting PPPoE session started on my ASA 5505. The debug output says that after negotiation of PPP-authentication protocol ASA receives a PADT packet from ISP’s concentrator. To get more information I captured all packets on outside interface with WireShark. Packet-dumps (in .pcap format) are attached in this post. I have tried all possible combinations of PAP/CHAP/MSCHAP values in “vpdn group MYGROUP ppp authentication” command. If you take a look at the packet-dumps you can see, that in case of “PAP” – ISP’s concentrator rejects negotiation (PAP is not supported by my ISP). In case of CHAP/MSCHAP (that ARE supported by my ISP) – ASA acknowledges the using of MSCHAP v.2 PPP-auth protocol, which is actually not supported by it…
Judging by MAC-addresses of ISP’s concentrators it is visible that Cisco’s equipment also is used.
The questions is: Why ASA acknowledges using of unsupported ppp-auth protocol during negotiation and what I need to do to resolve this issue? (ISP’s support says, that they cannot change PPP-auth protocol negotiation order. Also they says that I need to contact with manufacturer of my equipment).

I've been having this issue for about 3 months now, off and on, never seemed to be predictable but started happening more and more, which prompted me to look into it.
Currently, the DSL Modem is configured in bridge mode with the ASA handling PPPoE. The WAN address is being assigned via DHCP. The ASA is running 8.2(1). The WAN interface will drop it's DHCP lease and will not renew it without power cycling the DSL modem. I did a little bit of googling and found mention of setting "dhcp-client client-id interface outside", specifically this was an issue pre 7.2(22), but doesn't seem to affect my situation. Originally, I had the MTU on the outside interface configured as 1500, changing it to 1492 has not resolved my issue either.
I've enabled PPPoE and DHCPC debugging and posted the results below when the event occurs, I'm thinking this is moreso a PPPoE issue than it is a DHCP/DHCP Lease issue as I am not seeing any debug messages from DHCPC.

I just bought a 5505 to learn from and am trying to attach my VDSL modem as a transparent bridge.It goes....
Laptop >>> (VLAN1) Cisco 5505 (VLAN2) >>> VDSL modem >>> internet
X.X.X.10 >>> (X.X.X.254) ------ (Y.Y.Y.254) >>> Y.Y.Y.10 >>> A.B.C.D.
I'm using the ASDM, if I configure VLAN2 with the IP address of the VDSL interface I can ping the modem from the console session via Putty. If I take that off and configure up the PPPOE client I can't ping the VDSL modem, I'd expect that. If I then add in an IP address to the PPPOE client config like I assigned to VLAN2 it doesn't ping either.If I can't ping the VDSL modem I don't expect it would work but it seems I can only either give it a static address which pings but has no pppoe or give it a PPPOE config which means I can't ping the VDSL. why I can't ping the VDSL modem when the interface is set as PPPOE with an IP address?Presumably if I'm on the ASA console doing pings from there to the modem then I'm ruling out problems with the routing from the laptop (trying to isolate where the issue is)

I am trying to get a Cisco ASA5505 to get onto the internet using PPPOE through a Netgear DG384 ADSL router. I have the Netgear in Modem only mode - if you put it in Router mode internet access works fine. When I change it to Modem mode, the error I get on the ASA is PADI timeout. Looking through the config I think I am missing a Global NAT??Also not 100% on the best way to set the IP - we have a static IP from the ISP. Do you set the interface to use DHCP and get this address or set it statically? Then do you put the setroute option or put in a static? [code]

How can i determine the current PPPoE session duration on ASA 5500 Systems? If i use the different CLI commands like "show vpdn session state / show vpdn session pppoe state" the output says:
State: SESSION_UP Last Chg: 593595 secs.
The ISP is forcing a reconnect every 86400 seconds, so the value can't be the actual duration of the pppoe session. Does it only indicate the link duration to the attached modem or interface state? Is the only way to detect interruptions of the pppoe session with debug and syslog?

We have a Cisco ASA 5510 with:
-version: asa845-k8.bin
-ASDM: asdm-711-52.bin
Interface "Outside" is a PPPOE configuration.We currently have 36 site to site VPN connections up and running through the "Outside" interface. Now when we try to add, via ASDM, a new site to site VPN connection, we can not choose the "Outside" interface. The interface is just not available. All other interfaces are, bot those are inside interfaces.
I tried running ASDM on a different computer (thought that ASDM or java got corrupted perhaps), but the same problem appeared.Now when we "shutdown" the outside interface and "no shutdown" it again, the "Outside" interface is available again when you add a new site to site VPN profile.
Sidenote: if we check the current profile of a succesful running site to site VPN, it say's that it's using an inside interface. But that is, ofcourse, not possible.

I have 2 public ip, 1.1.1.1 anda 1.1.1.2. I'm connected to the ISP using PPPoE. I also have a router and a firewall. I want to assign 1.1.1.1 to router and 1.1.1.2 to the firewall. I do not want to NAT 2 times (one in router and one in firewall)That's why i want to bridge Fa0/0 and Fa0/1.Could this be done in Cisco router? I've done this command but it's not working as i want. I'm using bridge irb and bridge-group.

I'm trying to connect to an SMTP server using telnet via putty. Not just well known domains such as bigstring, aol, gmail, hotmail etc but also endless amount of not known or not popular ones.The problem is that although nmap says that port 25 is open, I can not establish any connection to ANY SMTP server (it just timeouts).I have tried disabling my firewall and using a proxy, but it still doesn't connect and now I've ran out of ideas. I also tried to disable my avast as well as legally used ip switcher program to make sure the problem is totally independent from my ISP.

I have a web cache server, and I redirect all the HTTP request to it using WCCP.
Everything works without a problem, however I have a monitoring system that every minute tests the access to some customer sites that are hosted inside our infra-strutcture.
As soon as I configured the WCCP the monitoring system complains of timeouts accessing those sites, about 20% of the requests start to fail (timeout).
I don't think it is the fault of the cache because in the WCCP ACL I exclude all traffic that comes from my monitoring system. However as soon as I turn of WCCP the monitoring system never ever gives timeouts accessing those sites.
Is there anything I should do in WCCP to tweak it? I have WCCP configured in my core gateway that is a CISCO 3750.

I have been having trouble with my DSL-2730B router. I am running a home network with a wired desktop connected via ethernet, two laptops, one desktop and three ipods connected wirelessly to the router.The problem is that at seemingly random times during the day the ability to connect to the internet is lost on all devices (wired or no). I also often lose the ability to connect to the router's homepage (settings) and upon inspection have found that when I ping the router I get time-outs (or sometimes destination host unreachable). This occurs on both wired and wireless at the same time and usually lasts anywhere from 10seconds to 10minutes at a time. I have reset the router numerous times including a reset via the web browser, unplugging the router and reconnecting and also have done a factory reset to attempt to solve the problem - all to no avail. As I am writing this I am using a different older router that so far (as of an hour) has not had the same issues.I should also mention that this happens regardless of which devices are currently on the network. I have had this problem with the wired-connection by itself and with my wireless laptop by itself.

We have recently put in a new 2901 router to be our IPSLA router and after adding 430 operations to it (215 ICMP and 215 UDP jitter) to cover off our state wide sites, it's reporting over half of them as timing out. Over the day, the timed out operations change so that our monitoring system shows the operations as down most of the time and up or warning state the rest of the time.
Some of the remote routers are reporting "SLA_FORMAT_FAIL" errors but I cannot find any references to this error.A ping from the router to the remote site router returns a ping time of 50ms or less and the network links are not conjested so QoS shouldn't be getting in the way. Our QoS policies would mark and prioritise the UDP jitter test traffic and the ICMP would be in the default class.
The 2901 is running 15.2(4)M1 and has 512MB RAM and 256MB flash. It's single homed into our core network switch. I've heard stories of 2900 series routers hosting 1000's of operations so I don't think we're taxing the router. CPU is sitting around 5% and memory is around 20%.
Below bits are for one set of operations.

I have set up a new wireless network for a customer and they want to use the guest portal for som users.The problem that I am expering is that on a particular site with many small buildings user complains that they have to reauthenticate using the webportal when moving between the buildnings. I have tired extending the idle user timeout on that particular wlan in the cisco 5508, but I still having this problem.
I would actually like if the user login via the guestportal at the beginning of the work day and after say 4-5 hours they have to reautencitcate.And if they loose network connectivity (moving between buildings, iphone/andriod shutting down wifi adapter, etc) they shuld be fine connecting again because they have aldready authecnticated once during the last 4-5 hours.
Is this possible via the ISE?My second question deals with 2.4 and 5 Ghz band.I use AP groups on each of my distribution areas. All groups have the same SSID but diffrenet egress interfaces (interfaces groups). And in some of these I want to save the 5 GHz band for voice over wlan and in others i would like to use both bands.
Do I have to create diffrent wlan profiles with diffrent radio policys and same SSID or could I do this in the AP group settings using RF-profiles?

So I recently purchased an E4200 to replace my aging and slightly ailing DLink DIR-655 which as served me well for going on 5 years. The part of the DLink that was giving me the issues was the wireless, the routing and switching worked fine however.
I do quite a lot of streaming of media from my home machine outside my network through the internet. Most recently I've been using Kalemsoft Media Streamer on my HP Touchpad, however I've used Zumocast, Windows Live, Splashtop, and a few others. I havent yet tried my PPTP VPN through the router for an extended period of time to see if it reflects this issue as well though.
Since replacing my 655 with the E4200 I've started experiencing a timeout issue. It seems to be semi-consistant and only happens after time of unuse or extended use (I havent timed it yet to see if it always happens after the same amount of time though).
Basically what occurs is this:
I'll be watching some video or listening to audio streaming from my machine and after a period of time (usually a long period of time) it'll suddenly lose connection, requiring me to re-connect through the software, like the NAT translation is timing out or something.
How it USED to work is this: It'd basically work until I stopped streaming.
My setup:
AT&T Uverse set to DMZPlus aiming towards my E4200 WAN port (sitting directly in place of the 655 I used to have)
All machines on the network are gigabit. I have ports 7000 and 7001 open for Kalemsoft Media Streamer on the E4200 per the specifications of the software.
The software understands UPnP so I have nothing specific forwarded on my machine, but I didnt previously either.

We were having a discussion of ios firewall vs. asa for smaller clients(less than 50). On using ios firewall(zbf or cbac)and an asa 5505/5510. One of the arguments brought up on using ios firewall on the router is that a router will do an ip sla failover. I have configured a number of isr's for this and i know it works good.

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

I'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.
