Cisco ASA 5505-trouble after weekend

[brettpenza]

We've got a Cisco ASA 5505 firewall in a high school setting.  About 600 users internally.  The network is usually running fine.  However, on Mondays, or this week Tuesday (after a 3 day weekend) the firewall gets very hard to find.  Since it is the only access to the internet, most users are denied access.  I can't even ping the firewall on most of the clients, though it is occasionally accessible.   All the equipment appears fine.  I try rebooting the switches and firewall.   Sometimes it gets me a few minutes of up time.   Through all of this difficulty, there is no problem accessing information internally (server folders and files, client signons, all fine).  

Strangely,  the next day (after I'm ready to start buying replacement equipment)  everything is working fine again.  

Someone told me that I should check the logs and go from there.  I will do that tomorrow (if I can connect again), but does this make any sense to anyone?   

How could a problem which appears so dire, become completely resolved the next day?  

Thanks.

Brett,

Another thought I had is actually something that happened to me in July, which produced similar symptoms to what you are seeing and sent me on a wild goose chase.  When the issue is happening (and it's Monday so maybe you'll get lucky), see if you can get into you ASA and view the real time logs (or better yet, send them to a syslog server and save them nightly so you can search for them after an occurrence instead of needing to catch it red-handed). 

Look for a blue message to the tune of:

"SA-5-321001: Resource 'conns' limit of 280000 reached for system"

It is basically an intermittent DoS attack run by an infected machine on your LAN that uses up all of the connections so that services randomly stop working with what appears to be no rhyme or reason.  The beauty is that if this is the problem, the ASDM logs will show you the offending LAN IP, so you can track it down and get it off the network or clean out anything malicious.

Attached is the actual screenshot I took in July when I discovered the issue. The client IP below the messages ended up being the infected laptop causing the problems. We removed it and they've had no issues since. There is also a fair amount of info you can find on google if you search the log message above.

If this really does only ever happen on Monday or Tuesday, perhaps you have someone on your LAN with an infected laptop that only works from the office on those days and works from home/travels the rest of the week?

Thanks , 

That sounds like a great possibility.  I will check it out on next downtime. 

[brettpenza]

Okay.  Here is a copy of the log from the Cisco 5505 ASA during a spotty internet downtime.  Everything in the inside network is functioning fine (internal folder/file sharing, signons,  apps )  but many cannot get to the internet (everything goes through our 10.0.0.1 -Cisco 5505 ASA Firewall). 

I see lots of warnings, but I am not an expert here.   If anyone can check the log and see if there are any glaring things that would be causing this downtime,  or additional suggestions. Thanks.

Hello

Would you also:

Clear xlate <---- when applicable

then show
Show process cpu-usage sorted non-zero
Show Version
Show log
Show local-host

Hi, 

I'm getting closer to what looks like the problem.   show local-host connections is revealing that my inside connections is moving upward in the 200 - 300 range over about 10-15 minutes time.  But my outside connections are up over 1800 for the same period.   

Apparently this number just keeps climbing . 

Then I get "resource 'conns' limit of 10000 reached    and the ASA goes off-line. 

Is there something I can do to stop the outside connections (of which we shouldn't really have anyone coming in from outside).    Some settting I can put in place to keep the connections down in the safe area?    We do have unlimited set in our ASA. 

Not sure if I really understand what outside "connections" are on this firewall.    Are they actual devices from the outside?    

Here are the :

Brett,

the odd thing is that you have an unlimited license, so the amount of connections shouldn't even matter. Either way, I am not sure if this thread already contains your full configuration, otherwise, can you post it ?

[brettpenza]

Here it is . Thanks.

Hello

Check out the tcp idle/half and udp idle timeout values applied, This seems quite high to have idle and half open connections?

timeout conn 8:00:00 half-closed 8:00:00 udp 0:10:00 icmp 0:00:02

compared to the Cisco ASA defaults -
timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02

Also do you really need the FW to perform DNS - I don't see anything requiring this and you have dhcp relay enabled but it seems your dhcp server is internal so why do you need relay on the FW?

I moved the timeouts back to default.  Not sure how they ever got set the way they were. 

Things are running.  Hope this fixes it. 

As for the DNS and DHCP.   Yes, I think you are right that they don't need to be there. Our Windows 2008 servers do this and we forward from the servers to safedns.com for web filtering.  I am hesitant to touch the config right now since things are working.   

But,  do you think having the DNS, DHCP settings are slowing us down, or are they just bypassed?  Exactly how does the Cisco process that they way we have it currently set?  

Thanks.

Hello

glad to hear it's working -well and least to now!  please let us know if you begin to experience this issue again!

Yes, I hesitate to say it is all set. It is a funny thing, after 3 or 4 years with smooth service and never a thought other than a very infrequent reboot, these last 3 or 4 weeks have been quite stressful with the whole school getting all bent out of sorts.

In any case, the cisco FW is quite a unique beast compared with some other very user friendly solutions. And while I've had a very varied career in IT, I never really had to spend a ton of time configuring a Cisco Firewall.


I owe quite a bit to several of you who have helped me through this. I have learned a lot and your posts have led me toward a much greater understanding.

Thanks very much. I will certainly be giving you all as many points as I can for your efforts.

I am thinking that it might be a TCP SYN attack or something similar. Try and add the below to your global policy default class:

policy-map global_policy
 class class-default
  set connection conn-max 1 embryonic-conn-max 1 per-client-max 1
  set connection timeout embryonic 0:00:00 half-closed 0:00:00 tcp 0:00:00 dcd 0:00:01

[brettpenza]

Wow, putting in those two set connection statements completely shut us down.   I had to remove them to get service back. 

Any idea exactly what those statements are intended to do?

Thanks.

[Georg Pauwen]

Brett,

my bad...these settings are very aggressive, too aggressive, I should have given you values as the ones below. My apologies, as it shut down everything...(:

The purpose is to mitigate syn floods.

set connection conn-max 1000 embryonic-conn-max 3000 per-client-max 1000
set connection timeout embryonic 0:40:00 half-closed 0:20:00 tcp 0:20:00 dcd 0:00:01

I do  appreciate all the assistance here.   Unfortunately, we are still not up and running consistently. 

I have been running  show xlate, clear xlate,  show conn,  clear conn.   

I have taken suspicious ip's and added them to a group host to block both in and out.  But that is like treading water with a teaspoon.

The show conn count is just creeping up way too fast.  I am a novice, but we go from 0 - thousands in a few minutes.  Then the internet access shuts down.    I clear the connections and we can work again for a few minutes.   Is this normal?   

See the current config below.   This is obviously very frustrating.  Not sure how we went from 100% uptime to this.  We are a school setting with about 600 people.  Why are we getting thousands of connections grinding to a halt?   I have blocked all incoming and still the count grows. 

Thanks for any suggestions.
