Cisco Routers :: VPNs Between RV042s (v3) Keep Dropping Telnet Sessions

Jan 26, 2012

I have recently installed four Cisco RV042 v3 VPN routers for a customer of ours to replace existing Nortel Contivity 1010 devices which were providing VPN tunnels from the customer's 3 branches to their headoffice. The original Nortel devices were working perfectly but the customer wanted some firewall rule changes and the Nortels were proving to be somewhat inflexible and incomprehensible in their configuration hence why they were replaced.
 
When installing the Cisco routers I configured the VPN settings to match the Nortel device settings so that I could swap out a branch at a time without taking the whole setup down for a day.The customer has a Unix based dumb-terminal application running on a server at headoffice that they access from their branches using terminal emulators on Windows PCs and thin client hardware devices that support vt100 terminal emulation.
 
Prior to installing the Cisco RV042's everything was working fine. Now they are using the RV042's they keep getting the sessions from their branches dropped. Both PC users and thin client users are losing sessions and it happens with active and idle sessions. I have checked the logs on the routers when users are disconnected and there is nothing logged at that time (other than my login)... I had thought maybe it was to do with tunnel renegotioations so I have set to phase 1 / phase 2 SA timeouts to 86400 & 28800 seconds respectively but this has had no effect. I had also seen somebody advised disabling 'SPI' in the firewall... I have tried this and it makes no difference.

Cisco VPN :: 2811 HTTPS Sites Hang Through Web Vpn

Jun 27, 2010

Using webvpn on a 2811 w/ adv ent 12.4(20)THTTP sites work fine (in the url-list)
 
But when we try to use an HTTPS site, clicking on that site just hangs forever.  Debugs show the connection is making it, and the servers are getting the connections...
 
The destination servers are using self-signed certs, as well as the router.  They are not requiring client certs.

Cisco LAN :: 3750 - Range Command / Session Hang

Oct 18, 2012

I've noticed that when using the range command to configure multiple interfaces on a 3750 the SSH session oftens hangs. It's seems the more interfaces in the range command the more often it hangs. I have a feeling it also spikes up the CPU. Doesn't seem to be related to a specific version of code.

Cisco Switching/Routing :: 3560 Switches Hang Off With Sub Interface

Jul 22, 2012

Was building a small network in Cisco Packet Tracer and ran in to an issue.  I have 4 routers running OSPF, and off one of the routers I have 5 3560 Multilayer switches.  The router that the switches hang off of, I have a sub-interface with dot1q encapsulation, set for vlan 10 and an IP Address. 10.14.16.1/24.  The switches have interface vlan 10 configures, and have IPs in the same subnet.  From that router, I can ping/telnet to all the switches without issue.  My problem arises when I try and reach those switches from any other router.  OSPF is set to redistribute static and connected subnets.The routing table is populated correctly on all the routers.  When I ping and trace the packet, it looks like it makes it all the way to the respective switch, but the packet never makes it back.  I've played with the default route on the switches to no avail.  Am I trying to implement this incorrectly, or am I just missing something?

Cisco WAN :: RV082 V4.1 Internet Hang Until Cold Restart On Dual WAN?

Dec 22, 2011

I am having issue with a RV082 with firmware:

v4.1.0.02-tm (Sep 16 2011 18:40:48)
 
On setup 1 I have;Using 2 WAN, 1 from fiber 5mbps symetric fixed public IP and other is DSL private dynamic dhcp address 3mbps/900kbps

 On setup 2 i have:Using 1 WAN, from fiber 5mbps symetric fixed public ip Both router have exact same firewall configuration, subnet and port forwarding and we have the seccont backup DSL coming in a few day for setup 2.on both setup, the RV082 is the main internet gateway/firewall for a set of server...
 
Setup 1 work perfectly and been online for 2 week (since install) without issue
 
Setup 2 worked for 2 day then had to reboot, then work for few days then need reboot, now it look like it need to be rebooted every day. the internet just stop working and a simple reboot does the trick... also, when that happen I can stil remote in server that have port forwarded in the router or connect to router management port, but internet on the server is down... I tried opendns and google dns on both WAN connection and still no luck.I have followed instruction on various support forum;

-more reliable dns server
-lower MTU
-failover vs load balance
-disabling SPI and DoS protection
 
at this point I'm about to swap both router to see if it not a defective hardware or disconnect DSL WAN on setup 1 to see if its more stable but the whole point of installing this router was for Internet redundancy which so far dosent work as expected.

D-Link DIR-655 :: FTP Software Would Hang / Change Directories On Remote Server

Jun 17, 2011

One of the companies I work for uses a DIR 655 router. I'm having some trouble using FTP there.Initially the problem was that FTP software would hang or give errors when trying to change directories on the remote server. This problem went away when I switched from passive FTP to Active FTP.Now using Active FTP, the files appear to be uploaded with no problem. However, on closer inspection, the uploaded file has 0 bytes on the remote server.

We are uploading from a Windows 7 machine and uploading to our Web Hosting Company's Windows Server. I've actually written the one piece of software that is showing this problem but it uses a widely known open-source FTP library written in .NET. I've never encountered either of these problems with my software until I encountered the DIR-655.The other FTP software client I've tried is FileZilla. It has the same problem, 0 bytes files when using Active FTP.

One solution I've seen on DSLReports was to disable the Stateful Packet Inspection part of the firewall (known as SPI). This is really not a good solution for two reasons. Number one, I do not have access to the router's firmware/ configuration. Number 2, the company has a DIR-655 because they want the additional security. If we're going to disable SPI it just defeats one of the major purposes of owning the DIR-655.

Dell :: Inspiron Q15R Laptop - Half Of Websites Attempted Hang With IE9 / Windows 7

Oct 7, 2011

We have just got our daughter a brand new Dell laptop for her birthday, it is fine apart from she cant get into half the websites she wants to. On these websites internet explorer just hangs.

Examples of hanging websites are:Argos, Travel Republic, Easy Jet, Vue Cinemas, Bin weevils, National Rail, Expedia, Ebookers

The laptop has Windows 7 and Internet Exolorer 9.I suspect it is something to do with the dreaded Flash but the laptop has Adobe Shockwave Flash Object enabled and any attempt to download Adobe Flash Player results in a 12% timeout download (always 12%)

Funnily enough I have an old Dimension 5000 which behaves in exactly the same way including the 12% download but I expected a brand new laptop to work..Is this a known bug with Dell products ie. you cant access half the websites on the internet without a load of grief ?

Cisco WAN :: ASR1004 SSH 2 Sessions Terminating

Apr 24, 2013

I've got a problem with an ASR1004 running "asr1000rp2-adventerprisek9.03.02.00.S.151-1.S.bin".

When I'm performing extended ping tests using a tclsh script i'm geting this error message:

ASR_X1A2#ping 172.27.1.250

% Authorization failed.

When i'm pinging 12 diffrent destinations this happens to about 3 of them.

Checking the logs I found this:

Apr 24 19:42:56.071: %SSH-4-SSH2_UNEXPECTED_MSG: Unexpected message type has arrived. Terminating the connection

In my entire backbone this is happening only in this equipment, I've checked the connection between my ASR and the TACACS and it's OK, no packet loss. CPU and MEM are OK too.

We are using ACS 5.1 in our network. We have created users and grouped them as per the requirements. We want to restrict the user sessions in the network. A user should authenticate and able to access a network resource. But when he is active with that session, we need to block him from another successful authentication. We want to avoid multiple users using same user credentials for logging into the devices. whether this can be achieved by making configuration changes in ACS.

Cisco :: ASA 5505 Licensed Limit For SSH Sessions?

Sep 11, 2011

I have the default license for a ASA 5505 and this last Friday I received the attached log for SSH sessions through this firewall; we want to be clear about this issue. This limitation has to be with the 10 Inside Host or the Total VPN Peers limitations in this license? This firewall exists only to agree with a PCI requirement between our router and a communication with a Payment Card Industry Brand, all of this in the same site.
 
ASA5505 <164>Sep 09 2011 10:42:08: %ASA-4-450001: Deny traffic for protocol 6 src DMZ:X.X.X.X/2479 dst DMZ1:X.X.X.X/22, licensed host limit of 10 exceeded.
 
I hope that the communications through 22 TCP port, are not countable for license propose.
  
Licensed features for this platform:
Maximum Physical Interfaces  : 8
VLANs                        : 3, DMZ Restricted
Inside Hosts                 : 10
Failover                     : Disabled

Cisco AAA/Identity/Nac :: ACS 5.4 - Active Sessions Over The Limit

Jan 1, 2013

I've looked at the forum posts and the document post, and I understand the explanations. My question is, under system administration>max user session global settings, would setting a timeout (say 1 hour) purge these sessions?
 
Under access policies, I am not enforcing max concurrent sessions per user, due to some of our devices using a generic log in. But if I understand the explanation, and my understanding might be wrong, then setting an expiry timeout should purge the accounting sessions, right?
