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
I have a customer who wants to disable cdp on all switches for securtity reasons. The same customer has also LMS 4.0 installed.
When disabling cdp, does it affect the topology services on LMS? Can you still see the topology tab on device manager or the topology map of the entire network?
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:
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?
I wanted to know the maximum VPN client sessions (using the Cisco VPN client) and Site-to-Site VPN tunnels that I can connect to my ASA 5505 simultaneously.
In other words, if I have x VPN clients and y Site-to-Site tunnels, at any time, does x + y have to be <= 10 (Total VPN Peers)? If yes, can I upgrade to the security plus license to increase the Total VPN Peers to 25?
Licensed features for this platform: Maximum Physical Interfaces : 8 VLANs : 3, DMZ Restricted Inside Hosts : Unlimited Failover : Disabled VPN-DES : Enabled [Code]...
my company has used Split Tunneling for all of our VPN uses, however we recently purchased 2 ASA5505s for use at various jobsites, and have been running into problems with Local Network Administrators blocking certain traffic that we need to operate. They allow full VPN connectivity to traverse their networks, so we are able to use our LAN Resources over the split tunnel no problem.
We have it set up as a Dynamic L2L Connection, and this ASA is operating flawlessly minus the traffic being blocked upstream by the network admin. Our VPN topolgy is Hub & Spoke. Below is excerpts from our config on how the VPN is set up: [code]
What we'd like to achieve is being able to pass ALL traffic (LAN & Internet) through the VPN tunnel, then be processed by the Hub ASA (192.168.9.1) on the other end. I am guessing crypto map + routing would have to be changed?
access-list to_hq extended permit ip 192.168.101.0 255.255.255.0 0.0.0.0 0.0.0.0route inside 0.0.0.0 0.0.0.0 192.168.9.1Disable NAT on Spoke. Is this how I would go about doing this??? We need ip address dhcp setroute so our ASA can find the other end and form the VPN tunnel, and I am not sure how this would affect things. [code]
I am planning the upgrade of an ASA 5550 Active/Passive cluster from 8.0 to 8.2 according to the "zero downtime upgrade" documentation available in the web.
I do not have another cluster for comprehensive testing, but I executed a simple migration procedure on a tiny 5505 and neither licensing features nor the configuration (the command sintax) were affected by this process. I know this is something to care about if you go to 8.3, but this is not my case.I browsed the release notes of 8.2(5) and no special disclaimer was found by me with respect to this release. So everything should work just fine, but I would like to double check for input with respect to these two subjects:
1.Will the licensed features (vpn, concurrent connections, etc) be preserved? 2. Will the configuration be preserved ?
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]
We are planing on offering low end ASA 5505s as a customer offer to connect their network to our cloud as this is a business requirment. However, one of my colleagues is convinced that the license for the 5505 is *not* based ont he number of IPSEC endpoints, but the number of distince connections via *any* tunnel. So, according to him, if you have a license for 10 IPSEC endpoints, if you have 11 people connecting via *one* tunnel from a customer's network to our cloud, you go beyond your license.
I'm getting an "ACL does not match proxy IDs" error that I'm not able to troubleshoot, googled this with a lot of results, tried some; but nothing applied.I have setup 2 tunnels, 1/one from a pix 515e (office) to an ASA 5505 (hosted server) for my guys to access the hosted server2/A second one from the ASA 5505 to my client's firewall so that its equipments can reach the hosted server and from the hosted server reach the equipments.Both tunnels are working fine, my issue comes when I'm trying to join my clients equipments from my office, ie cascading the tunnels.
This is the first time I'm trying to cascade some tunnels, no issues with other vpns I have been building.I'm joining the configuration of the pix and the asa and an extract of the syslogs showing the error, any obvious error I haven't seen!
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
We currently have a tunnel configured between 2 ASAs
1- Is it possible to assign 1.5 Mbits of Bandwidth(BW) to this tunnel?. Then if Tunnel number 2 is configured I could assign 2 Mbits to that one for example?
I am not referring to prioritizing certain type of traffic over the IPsec tunnel, I am referring to Tunnel 1 has 1.5 Mbits of BW guaranteed for all traffic that goes thru it. Same for tunnel 2
Then
2- How to monitor the amount of BW in an IPsec tunnel?
We just recently upgraded a 5540 ASA running 8.2 to a 5555 running 8.6. I have a question concerning disabling proxy ARP with static nat rules in place. We have several instance where devices in a dmz have a static nat entry to the outside and a static nat entry to the inside using the same IP. My question is if we disable proxy arp on the inside interface would that cause device on the inside not to be able to reach the device in the dmz? From what I have seen you don't want to disable it on the outside interface due to all the static nat translations. But we have some that are have nat translation going to the inside as well. How does proxy arp come into play there? Below is a diagram of an example of the setup I a referring to. This is on the new 5555 running 8.6
We have dynamic NAT configured from inside to outside interface, but still it is showing NAT entry as below.
"NAT from inside:177.26.99.10 to outside:177.26.99.10 flags Ii"
Expected NAT entry should as below :
"NAT from inside:177.26.99.10 to outside:111.111.111.111 flags Ii"
We were considering implementing "ip verify revert-path" .Hence here i am thinking whether xlate-bypass is the issue here and implementing same with "ip verify revert-path" woud be a good idea.
I have a RV082.I need to disable the firewall, since firewalling is done better elsewhere.However disabling firewall Remote management on wan ip is forcefully enabled.I don't need Remote management, keeping it enabled is a security risk for my setup.I don't understand the rationale behind the choice to forcefully enable remote management if firewall is disabled.Is there a way to disable both firewall and remote management?Or at least a workaround?
I'm on firmware 2.0.0.19-tm on a probably v2 hardware. (Cannot find this info in the web configuration).This is not the newest even for v2 hw but I cannot afford to break it trying to upgrade the firmware.Moreover no release notes for firmware releases refers to a correction of firewall/remote management behavior.Is this behavior also in newer firmware releases?
We need Solution for disabling Anti-Replay on the Firewall for a specific tunnel. ASA 8.4(2) ) does not support disabling Anti-Replay on specific Ipsec tunnel , is it true , then if we want to disable Anti-replay , what we have to do in ASA5540 .
I have just logged into the ASDM for my 5520 and can see under the "Firewall Dashboard" tab that I can enable these graphs/stats, why would they be disabled? So I was wondering if I enable these and they use alot of memory how can I disable them again?

i bought a cisco 2950 series switch to play around with and im trying to set it up to SSH. I have google'd a bit on how to do this and i've sort of hit a wall... i have downloaded the cryptographic image from cisco's website, installed a TFTP server (think this is where my issue lies) but when i do the copy tftp flash global command i keep getting the error accessing "xxxx" message.I have tried allowing the server through windows firewall, disabling windows firewall, allowing access through the router..
We have a PIX firewall 515E running version 6.3(4) and there are few site to site VPN's installed on it. We want to find out the isakmp key for those VPN tunnels. On ASA, We can run the command "more system..." and it displays the key, but it seems it doesn't work on the PIX 515E.
I have one ASA with two tunnels. Each going to a different 3rd party Checkpoint firewall (site A, site B) Each site has two servers (A1, A2, B1, B2)I can only connect to A1 and B1. any connection to A2 and B2 fails. I have defined B2 and A2 in the crypto map to be protected.If I only have B2 or A2 in the crypto map ACL then the tunnel fails. Phase 1 does not come up. Its as if the ASA is ignoring the entries for B2 and A2.ASA running 8.4(2).I have also trashed the VPN and built via the wizard, same result.
I tried looking in ASA documentations but unable to find out that how many IPSec Tunnels can be terminated to an ASA cluster. I have 5545 running only two IPSec Tunnels so far but need to terminate 18 sites all up and would like to confirm how many tunnels we could terminate? Is there a limitaion to it?
I am setting up a network that will use the 1941 router with a cellular card (HWIC) to connect to the Internet for communication with remote stations in the field. The 1941 has a static IP address (166.142.xxx.yyy) on the Internet provided by the ISP (Verizon). The 1941 is connected via ethernet to the ASA5510. The end goal is to have the field cell routers (Digi Transport WR-44-R, also static IP) connect to the ASA5510 via VPN tunnels for communication back to the servers behind the firewall. I'm not sure exactly how to configure the 1941 so that the remote router can connect to the ASA using the public IP of the 1941 router. I have the 1941 working stand alone and can connect to the Internet and pass traffic, but I tried a static NAT to translate the public IP to the private IP of the ASA and cannot pass traffic. below is part of the 1941 configuration: [code]
Do I need to use VLAN bridging to accomplish the task or am I missing something with the NAT?
I currently have 3 pcs - one desktop ethernet - one desktop wireless adapter and one laptop wireless. I unplugged the desktop wireless a few nights ago - I have since been on the ethernet desktop fine but when I tried to log on with the laptop wireless - no deal. So I replugged the wireless desktop and then the laptop was o.k. to connect. This doesn't seem normal but I don't know. One unplugged pc on the network shouldn't affect the others should it?
I recently switched over to a new cable modem/wireless router, which is the Zoom DOCSIS 3.0 (Model: 5350-00-03). Me and my brothers have set up a second router, a Netgear N300 (Model: WNR2000v2), on the other side of the house. After the switch, our data usage has been increasing. I just want to know if having two routers affect more data usage.
I notice that SPI is disabled by default on the DIR-600 (in firmware 2.10 and 2.11 as well).Port forwarding still works with SPI on (use it for BitTorrent).So why is it off by default?Does it slow down things?
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'm in the throes of configuring my 5520 to supply different group policies based on LDAP group membership. I'm finding that no matter what I do only the default group is applied. I'm sure it'll be a simple fix - but I just can't see it. [code]
