Cisco Firewall :: ASA 5505 Connection Limit And TIME_WAIT Freezing Device
Sep 30, 2011My little ASA 5505 is working great The device appears to be artificially crippled and limited to 10,000 connections. This isn't a "CPU limit" it's just some fake limit in the device as far as I can tell.
The problem we have is that we are only using around 500-600 connections and CPU usage is only like 25%, and yet the connection count is pegged at 10,000 and locks us out of our network.
I am pretty sure this is because there are a lot of "dead" TIME_WAIT connections hanging around not being used. In our application we only have the couple hundred connections but they do move around a bit every now and then.
Is there anyway to get the device to ignore the "dead" connections and not count them towards the artificial limit on the device given that it's pretty clear the CPU / etc., is not utilized sufficiently. These aren't real connections, we only have a couple 100 established, they do just move around a bit however.
We are really only using 500-700 connections according to our servers, the others are just sitting in TIME_WAIT doing nothing.
Cisco Firewall :: 1921 - IOS Firewall (ZBF) Limit SMTP Connections From Same IP
Mar 14, 2013IOS Firewall (ZBF) Limit SMTP connections from same IP
we are running a Postfix MTA behind a IOS Firewall (ZBF) on a CISCO1921. Sometimes we get more than 2000 smtp login attemps like
postfix/smtpd[123456]: connect from (...) (...) postfix/smtpd[123456]: lost connection after AUTH from (...)
in one second. May be bruteforce or DoS ... nevertheless - we like to protect the Postfix MTA from this stuff.
Can we inspect the smtp and limit connections in a time period from the the same IP? Something like "not more than 10 smtp connections during 60 seconds from the same ip" .

Cisco Firewall :: To Put In ACL To Limit Inbound 2621
Apr 20, 2013I have a 2621 router - old. but works well.Need to put in an ACL to limit the inbound SMTP traffic to be FROM a specific set of IP's, and deny all others.
I have tried various combinations with no luck. Something obvious, I am sure.
When I do a show access lists 160 it shows all SMTP traffic being snagged by the SMTP deny statement. All other traffic works correctly.

Cisco Firewall :: ASA 5510 Ver 8.2 Rate Limit
Jan 17, 2012I'm trying to limit one of my inside hosts, since it's been a little of a hog. I have 3Mb available from my ISP via 2x T1. I'm testing this on a computer in a lab:
PC 10.10.10.10------Cisco2960-------- 10.10.10.1 Inside - ASA - Outside 208.66.x.1------------------------208.66.x.2-Cisco 2811-2xT1
Here's what I've tried so far, please see text in red:
***global (outside) 1 208.66.x.115
***nat (inside) 0 access-list No-Nat
***nat (inside) 1 0.0.0.0 0.0.0.0
[Code].....
It didn't work... I was able to max the bandwidth again. I also tried to apply service-policy to inside int, which didn't make a difference.

Dell :: Wi-Fi Limit Connection And Power Startup On XPS L322X
Feb 1, 2013I got my XPS L322X yesterday, and this problem occured from the first time I turned on my laptop. Everytime I turned on or restarted my computer, I could connect to my wifi router, and everything works well in the first 3-5 minutes. But later the wifi connection turned to "limit", and if I searched for the networks again, all wifi hotspots disappeared!
And if this problem popped up, there would be a follow-up problem -- I could not turn off my computer nor restart it! If I tried to restart the computer, it stayed on the "restarting" screen for 5 minutes, and a "power_start_up_failour" error warning later. If I then restarted the computer by pushing the power button for 5 seconds, it showed that the network adapter was disabled. Enableing the adapter would start this whole problem all over again!
Cisco Firewall :: ASA5505 - Inside Hosts Limit
Feb 18, 2012The ASA5505 I am working with has this from the show version:
Licensed features for this platform:Maximum Physical Interfaces : 8VLANs : 3, DMZ Restricted Inside Hosts : 10Failover : Disabled VPN -DES : EnabledVPN-3DES-AES : Enabled VPN Peers : 10WebVPN Peers : 2Dual ISPs : Disabled VLAN Trunk Ports : 0
This platform has a Base license.
Does the Insides Hosts :10 line mean that only 10 devices can be connected to the firewall at one time? I would like to connect an AP to one of the PoE ports and have possibly more than 10 connected. Is this possible with this ASA5505?
Cisco Routers :: RV082 Firewall - Limit Connections By IP
Mar 25, 2012RV082 - 1.3.2 I need to have RDP and pcAnywhere enabled to a customer site for remote support, but need to limit the incoming IP ranges to only our offices. I have the port forwarding set up and tested working. I then set up rules to deny all traffic on the needed ports and added rules to allow a few IP ranges from our office locations. I even tried a rule allowing all traffic from our main office but that also failed to allow RDP or pcAnywere connections.Now I can no longer connect from any of our remote offices. I followed the limited instructions that I found in another post but its not working.

Jun 3, 2013Worried about denial-of-service attacks. They have 11 vm's that share a connection and want to set it up so that there is a maximum amount of traffic allowed to hit each vm, so if there is a DDoS attack it will only affect that one VM instead of all the VM's on the same connection.

View 3 Replies View RelatedCisco Firewall :: 3389 Any Ability To Rate Limit Connections?
Dec 9, 2012I'm trying to determine whether Cisco has any equivalent (in any platform) to some of the existing firewall rules within our iptables infrastructure. [code] What this does, is allow port forwards on port 3389/rdp. However, if a single IP opens too many connections within a timeframe, it starts dropping new ones.This is a critical requirements for certain security scenarios, such as preventing RDP brute forcing. A similar principle can be applied to 22/ssh.I've had a look around, rate limiting searches generally land me on QoS based discussions. I've seen people ask similar questions and get referred to CBAC. Whilst I can see similarly worded functions there such as limiting "half open" connections, I don't see anything there that limits the actual number of connection attempts you can make.

Aug 7, 2012We need to have one connection with less internet bandwidth assigned to it than all other other connections. Basically it is a separate conection from all others, incoming just from one switch port and separate VLAN.I know this can be done on the switch by limiting the bandwidth allocated to a port,
however, is it possible to have the speed limited down, just before it goes to the internet, ie, on the ASA, rather than doing it on the switch?The firewall is an ASA 5505.

View 1 Replies View RelatedCisco Firewall :: ASA 5525 - Bandwidth Management (Rate Limit) Using QoS Policies
May 22, 2013 We have an ASA 5525 running version 8.6(1)2 and a 10 MG pipe. I have execs that want to limit bandwidth on users for stuff like youtube, stream media, and downloads. I found the article on ‘Bandwidth Management(Rate Limit) Using QoS Policies’ so it appears our firewall can do what we want. I’m not a cisco person. My knowledge is limited when it comes to configuration – that’s why we have SmartNet.
Can bandwidth be limited on end users and/or can they limit the ‘bandwidth rate limit’ to just youtube, steaming media, and downloads? If so, what should the limit be? and I’m assume this would be for ‘incoming’ traffic only? we’re running into some bandwidth hogs – usually youtube and/or streaming media. We have a Barracuda web filter which we’ve used to block and monitor activity but I simply do not have time to babysit this all day. I should also mention we do have critical data running up and down the pipe; such as credit card processing, DB replication between in house DB and hosted website, TPCx and EDI, FTP, and such that we don’t want restricted.

Aug 18, 2011 My company has a peer to peer network of 10 personal computers without a server. Operating systems from Windows XP to Vista. I've recently installed a Cisco RV120W Wireless-N VPN Firewall. It's configured in DHCP Server Mode with printers/copiers that have static IPs below the DHCP range.
I'm having a problem with certain stations being used for personal networking, shopping, etc. during business hours. Consequently I would like to limit internet access on these stations. However, some internet access is required because of online database software that's an integral part of our business. I've been reading in the Administration Guide about URL Blocking. Would it be possible to give static IPs to certain stations and then limit their internet access to 1 or 2 specific websites?
FYI, I've read about the Trusted Domains and Blocked Keywords but cannot quite understand how to parley this into the solution I need.
