Won't Allow Any TCP / IP Connections As IPSec Driver Has Entered Block Mode
Apr 6, 2011
I am having some trouble with one of our servers at work. Basically it won't allow any TCP/IP connections as the IPSec driver has entered Block mode. I have been advised by our external IT support (I can't get hold of him at the moment, that's why I am here ) to go into the command prompt and type: regsvr32 pdstore.dll but when I do this is can't find the file.What is pdstore.dll as when I Google this it comes up with nothing, so is this the correct command?

I need to block 4000 nodes (Ultrasurf, TOR exit nodes) and I've written a script that will ssh and copy in these objects (prob 100 at a time) into an object group and then put a blanket deny. I don't see a flood of traffic (occassional hits every other day, etc) but I was wondering what the impact would be? Can the ASA handle an object group of that size plus an ACL with it? Any way to block incoming connections from TOR/Ultrasurf?

After getting the cable set up (some new wireless modem that comcast gave us) we were able to connect to the internet once, after putting in the password, but after that the next day our computer would not recognize any networks at all, it's just say no connections are available.I already:-restarted computer,-reset modem (we used to have a router and a cable modem but now only the wireless modem)-rolled-back drivers,-disabled then re-enable driver (did NOT uninstall or reinstall)-opened the computer up, take out the adapter, tryed and got the dust off-unscrewed and rescrewed antenna- tested a laptop, and it had an internet connection - and probably a few other things which I can't rememberLast time on the computer, I uninstalled a few things with revo, ran registry cleaner, browsed internet, and installed a new nvidia driver (after the problems arose). I was able to install a netgear wireless usb adapter (which is how I'm on the internet right now), but it frequently gitters and I can't use the NetGear for very long seeing as how a different computer uses it.

I have an RV220w in office, which I have configure it for ipsec vpn connections. Behind router there is a NAS for file storage. [code]I have managed to connect to router from my home with ShrewVPN and I can ping every client connected to RV220w.The problem is that I can't connect to neither to router's web interface nor to NAS web interface or any other intranet web page ( the browser doesn't give any error, but keeps loading without showing the web page). Although, I can access web pages from my laptop.Also, in windows file explorer when I connect to NAS, although I can browse folders I can't copy files from my laptop to NAS and vice versa, I always get timeout error (I have checked the permissions to NAS and in addition I succeed to copy a small txt file 1kb, but no luck with bigger files).I also tried with QuickVPN client, but I had the same results. When I connect with pptp from windows everything works like a charm.My laptop has windows 7 64bit.

I have a hub and spoke network with over 100 remote sites that connect to me via ipsec vpn. One of these locations, the only one using FIOS coincidently, is initiating 200+ tunnels back to my side which is causing saturation issues on my DS3. (I can post config if requested), and how can I limit the number of active tunnels it's establishing?

We are planning to use an ASA 5540 to terminate about 3000 IPSec connections. The maximum supported IPsec VPN Peers for this platform ist 5000, so this should be ok in theory.
What is a bit unclear to me is what exactly happens when (for whatever reason) all 3000 clients try to connect at once ? Perhaps it's not at once but depending on timers this could mean 3000 incoming IPsec connection within 10-20 seconds.
Will the the ASA cope with it ? I can't find any info regarding this on CCO. It's also not that easy to test/simulate.

I'm now trying to implement a IPsec VPN network over transport mode in my simple network environment.I got two Cisco 2811 routers connected each other and each router hosts a client PC running Windows7.
I have finished the configuration on both routers and make them running over transport mode.However, as what it should be, transport mode indicates the communication between two end stations (two PCs) the client PC (install or configure something) to make the network fully works?

I have a Linksys WAG200G DSL wireless router and I recently got Network MAgic. When I am trying to connect to change the wireless settings, it always gives me the message that it cannot connect to the router no matter what password I enter! I even used really simple ones such as admin admin and It WONT connect. It gives me the message "Could Not Access Routers Settings". I have the ESET Smart Security AV & Firewall and I have properly configured them to allow communication of Network Magic. I should note that I CAN connect to the router through a browser.

you can configure a cisco 1905 router with vpn ipsec site-to-site in an aggressive mode? If so, any link to what I do? The VPN works well, but on site A, I had to configure a crypto map associating the IP address for site B (wich is dynamic), so if the connection on site B broken, I will have to configure another crypto map.
The scenario is:
Site A - ASA 5510 configured as a VPN concentrator and firewall for enterprise.
Site B - Cisco 1905 connected to Internet through a ADSL through a dynamic IP address and starting connection to Site A, bellow is the configuration:
crypto isakmp policy 10
encr 3des
hash md5
authentication pre-share
group 2
crypto isakmp key xxxxxxxxxxxx address W.X.Y.Z
[code]....

I got an ASA 5510 system currently in single context mode, with CSC SSM installed. Single ISP uplink to internet, no VPN. And now customer would like add another ISP uplink, without invest another box for HA.What come across my mind is make the current box into multi context. There's some area i need to concern and also need yours perspective on it.
Question 1: For making the firewall into multi context, am i need to do it from scratch, issue mode multiple command. Then rebuilt the current production config into one of the context, then another context meant for the new IPS uplink, and one admin context?
Question 2: For CSC -SSM licensing requirement, model ASA 5510 with security plus license is able to support 2 context. So if i split my firewall like what i mention in question, what exactly number of context do i own (admin, context A, context B)?
Question 3: For CSC-SSM module in multi context mode, so the management port of CSC SSM must attach at admin context?
Question 4: After configured all the policy and traffic to scan, how exactly i should do in order apply this policy to the interface? Should i only enable at admin context, then firewall service-policy rules, and apply it global, OR should i also do the same action on context A and Context B?

I am not able to connect to any webpages in normal mode, even after restarting i still have the same problem [However it works in safe mode with networking]. The network connections show that it is connected and the signal strength is excellent. I then have to keep restarting the laptop like 3 to 4 times and it works. Its kind of frustrating to keep doing this all the time and besides i am scared by restarting the laptop so many time can harm it.

I received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
In a redundant Sup-6E setup, the following configuration is supported :
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
If you invoke shared backplane mode, the following configuration can also be supported:
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
Here's the command and information about the "shared-backplane" mode :- [URL]
Currently, we have 2 SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:
1- One will be used to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
My questions are:
1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?

i got a Dir-655 router and Dell 1501 wireless -N mini PCI card (802.11 bgn compliant). Router was set to mix mode but my desktop Dell XP8300 can connect only till G mode.
1) I search on web and some said that i need to set my router to N mode only for my desktop to connect to N mode. IS THIS SOLUTION CORRECT??
2) Another issue was my sis got other old brand latop which can only connect to B mode, if i set to N mode only, she won't be able to connect it right?

I need to run an ethernet cable of about 60ft from the mpoe to the server closet. The path is rather challenging to pull the cable through. I was told that I could utilize the 66 block in the mpoe and the other 66 block in the server closet to make this run. Is that really possible? Just punch down the 2 pairs?
