EA6350 Question VPN

• Linksys ea6350 questions

  So for starters, I have 2 switches, one for computers and the other for IP phones, they're plugged into a wired router, while the router is connected to the modem. My client has a switch mini under his office that connects to the network printer and his computer to the switch of the computer, plugged into a wall outlet that went to the telephone switch that makes a loop from one switch to another, the Microswitch who messed up his Copier IP addresses and IP phone and made 2 ea6350 wireless routers go down Router 1 is connected via the PC port on an IP phone, so it can get an internet connection (lets call this RouterD router), it worked before this, but now I have problems. The other router is connected through another mini switch that goes to the switch of the computer in the wiring closet, so it is not connected through an IP phone like this, but it does not work either since plugged the Microswitch in the switch of IP phone (lets call this RouterU router). I tried to install RouterD with an IP address that differs by the main router (192.168.0.1) DEFECT in the wiring closet (192.168.0.2) and he had point to the default gateway 192.168.0.1 and a 24 regular but it won't always connect to the internet, the settings previously were even if the phone is able to call and receive calls. I have not messed with RouterU yet because I was trying to trouble RouterD. The previous configuration I don't mess with, I plugged it in and it worked fine. I would appreciate would like to thank all the assistance.

  I have reset both routers EA would then follow it and create one at a time:

  http://www.Northshore-it.com/Tips/how-tos/cascade_linksys/#LAN_to_LAN

  The routers value EA one IP address static to 192.168. #.63 and the other at 192.168. #. 64. to reconnect to the LAN to LAN after reconfigureing.

  Is there a bridge mode defining routers on environmental assessment? Connectivity-online Internet settings => IPv4-online Bridge Mode

  If so, you can assign both to fill the mode then you can connect the WAN port on each EA router to the router main host. Then the linksyssmartwifi could be used.

• Question VPN on Cisco 7206

  Hi Experts,

  We have a VPN configuration between a Cisco 871 router and a Cisco 7206 VXR router.

  The 7206 is a location of the hub and the 871 is one of the rays.

  The 871 uses a DSL connection to connect to the internet.

  Today we receive a large amount of newspapers on the 7206, newspapers are as below-

  14 Dec 17:47:48.326 is: % CRYPTO-4-IKMP_BAD_MESSAGE: IKE message failed the validation test or is incorrect

  14 Dec 17:48:57.078 is: % CRYPTO-4-IKMP_BAD_MESSAGE: IKE message failed the validation test or is incorrect

  14 Dec 17:51:47.383 is: % CRYPTO-4-IKMP_BAD_MESSAGE: IKE message failed the validation test or is incorrect.

  Can someone advise if there may be a problem with the DSL connection or if it means something else.

  Hi Imran

  Looking at the error message, the keys of encryption on both ends do not match. Make sure that the pre-shared keys are configured correctly

• Question - VPN on PIX

  Our PIX firewall allows any set up inside. In the past, we have tried to establish a VPN connection from inside our network to a hub on the Internet VPN and it did not work. We were told that do VPN behind a firewall is not possible (I don't remember who said that). However, last week we had a customer VPN to their network through our firewall. I don't have the details on the equipment or Protocol. Technically, I would like to know what can and cannot be done from the inside using VPN and to understand the reasons. We went through a few updates on the PIX from v5.0 to v6.2, and I suppose this may have something to do with it. If someone could help or point me to documentation that explains this in detail, it would be highly appreciated.

  Thank you!

  Lori White

  The big problem with IPSec through a firewall is not so much the filtering (specific protocols can easily be let go), but generally the NAT'ing or more precisely, the PAT'ing (Port Address Translation). VPNS use IPSec or PPTP usually, that use a protocol that is not TCP or UDP based (ESP and GRE respectively). Whe ndoing PAT however, it relies on a TCP or UDP port number to differentiate the different sessions and so when a protocol arrives who doesn't have it, it is usually deposited by the PAT device ' ing.

  Many VPN solutions are now a feature called IPSec via UDP, or via TCP or transparency IPSec IPSec, or whatever you want to call. Basically, the VPN client and the hub encapsulate IPSec ESP packets in a packet UDP or TCP depending on the implementation, this p [rescue can be PAT would have correctly and everything works fine. Your client was probably using something like that.

  PIX 6.3 code will support IPSec and PAT, but only for an internal IPSec session. You are the best solution is to see if any VPN software you are using supports a kind of UDP or TCP encapsulation, then you'll be off and running.

• VPN only 1 end allows the transmission

  Hello

  Worked on a question VPN site to site of weeks now and I still can't solve, would appreciate anyones help (where is Keith Barker when you need him ;)

  Basically, a branch on a 5505 VPN for the main office, simple site to another, everything works fine.

  Main office has a new building with a new 5515 ASA. you will need to move the VPN connection to this new ASA.

  created the tunnel VPN rises without problem (all good isakmp)

  However, only the branch can be seen to pass, he gets nothing in return. You can see on the end of the siege, he receives these packets transmitted but nothing in return. Let to believe that the issue is on this new ASA.

• VPN not iniate on one side.

  Hi all

  I have a bit of an embarrassing question VPN site-to-site framework. The tunnel comes from the other end, but will not initiate traffic on this end. I have a 7.0 (4) ASA 5510 and the other side is a 12.2 (18) Cisco IOS router on what appears to be a 6509. Both hosts are using public address. If I run a trace of this end he spends just by the ASA and heads to the internet like there is no tunnel at all. If pings aside other tunnel will be fine and then the ASA sends traffic through the tunnel.

  Any help would be appreciated.

  Scott

  Thanks for the update! If it's static static, then tunnel should appear fine when emanating from each side.

  Now, you said that when you have removed the restriction of port on the ACL IPSEC everything has worked well. So, the obvious question is, what is configured on the remote site. If it is configured for all Ports or specific ports. If all ports, then you need to configure your side to match the same. If not, I've seen behavior like this, where the IPSEC Security Association is created only if launched from a remote website where you have a 'LICENCE' IP and the side of the answering machine is configured with specific ports.

  Can you let us know what is the ACL IPSEC configured on the router.

  Kind regards

• What data is visible to others on my network Hamachi VPN?

  Original title: VPNs?

  My computer has, LogMeIn Hamachi, installed on it and is connected to a network server in a remote location. The dialog box that appears when you select and open the program indicates that there is a direct tunnel to one of it is used at the remote location. Is it possible that this person could access or watch the files on my computer without my knowledge?

  Glance, the program Hamachi or any other program that affect the operation of Microsoft products is a valid query. It is a serious matter, if you have some knowledge about the original question (VPNs) that you would like to register here for future reference it would be great. If it's not..., "shrug of the shoulders." Do not answer.

  Incorrect answer as to the interpretation of the translation.  This explains the price, not whether or not the I have people wasting time (that I did not.)
   
  You asked your question here - a place where Himachi is not supported.  Rather than allow you to waste your time more far - I pointed out indirectly your madness.  If you need more franchise:

  If you have a question about Himachi VPN - it would be wiser to ask here:

  Always ask those that actually support the product you have a question about - the operating system is just a vehicle to operate the product.  You have a question about the built-in VPN WIndows battery?

• VPN connection question

  In my workplace, there are two networks is the local LAN that connect other computers to the internet and the wireless network which my computer connect to and is directly to the internet, my question is that is it possible to connect to the LAN over the internet using the connection V P N if yes how? Please help me because whenever I want to read my emails, I have to put the UTP cable which will be sometimes annoying.
  Please indicate all the measures that are needed to establish the VPN connection.

  Ask it professionals about your place of work.  They know what is possible and what is not.

  Where I work, there is an available VPN that allows connections to the LAN from outside work.  If I use a laptop computer provided by the company, access the LAN just as if I'm at work.  If I use my PC, I get a link that allows me to access a limited number of resources, such as the email of the company.  I can, however, DRC to my desktop at work PC and can get access to the local network.

• Questions of Virtual Private Network (VPN) connection

  OK I did some research on the private network connections, and I have a few questions:

  • Is it true that a connection to a vpn is possible thanks to a transport to a Wi - fi (I want to connect to a network non - bes)?
  • As far as I know, you can connect to a vpn only if create you a vpn manually account via the phone options menu. Is it possible to programmatically create the connection without having to manually create the profile?
  • This connection can be established via a proxy server?
  • Any article or the sample code will be really appreciated

  BlackBerry Smartphones have supported integrated to connect through a VPN using WiFi.  Other transport routes are not supported out of the box for this.

  There is no way to programmatically configure a VPN.  Virtual private networks can be configured on a BlackBerry Enterprise Server and pushed to users.

  BlackBerry Enterprise Server is able to connect through a proxy server.  All of the BlackBerry Java API does not include API to manage proxy communications.

• Question of VPN & ACS

  Hello

  It's maybe a stupid question, but I need to learn more about security issues, so here's my question: If the remote end users can access their corporate network via secure VPN, then why do need ACS solution? Thank you to educate me.

  My examples are not too clear. You are right in that you can provide access to the server to your VPN users through AAA filters for the VPN concentrator.

  In the environment where I work, we also use ACS to authenticate wireless users AS5300 dial-up users and access to our routers and switches.

  Here is a link that I hope this explains a bit more clear:

• ACL VPN question

  I have two questions that regarding ACL is used in the instructions on the Card Crypto:

  1. the two devices VPN should have the same ACE in the ACL? I know that without the second ACE site B below will not see as interesting udp traffic, but the will of the vpn tunnel fails because the ACL is not the same ACE?

  That is to say...

  Site has

  Access-list 110 permit tcp 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  Access-list 110 permit udp 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  Site B

  Access-list 110 permit tcp 10.0.2.0 255.255.255.0 10.0.1.0 255.255.255.0

  2. once a tunnel is established it will send ANY/ALL traffic destined to the remote network through this tunnel. If the first ACE in the ACL 110 to Site A list is used to bring up the tunnel, only tcp from to 10.0.2.0/24 10.0.1.0/24 traffic will use the tunnel or all traffic from 10.0.1.0/24 intended for the remote network to cross the tunnel?

  I guess my thought is this. The ACL is only used to determine valuable traffic and once the tunnel is up it is a free for all. Or the ACL only allows traffic that meets the criteria specified in the ACL list to flow once the tunnel is established?

  Thank you

  Brian

  Brian,

  Your statement

  'Or the ACL allows only traffic that meets the criteria specified in the ACL list to flow after the tunnel is established'

  Is correct, only the traffic that meets the ACL crypto will go through the vpn tunnel and all other traffic will be denied. If you need UDP traffic to travel through the tunnel, you need crypto ACL on both sides and not only on one side, that is, SITE A.

  Hope this helps,

• Questions of VPN tunnel

  People,

  You can help me understand how I can fix the following issues I have with a 1721 router (Version 12.3 (8) T5) and client VPN 4.6.01.x please.

  BTW, the server at 192.168.3.2 is a file, DNS, WINS server and proxy for the LAN environment. All the staff of the PC is required to use the proxy but visitors on the 192.168.2.0 network can access the internet directly.

  Back to my questions. I have the obligation to set up a VPN tunnel to connect to a PC that is running Terminal Server services / remote desktop on a PC to 192.168.1.9. When running the VPN software on the laptop I get a login prompt and everything seems fine. I ping the addresses of router and that works.

  But the three things I don't understand:

  1. I can't telnet with great success to the loopback address of the router, as well as other addresses 192.168.x.x. very well, but why is it possible that I can telnet to the 192.168.4.1 loopback address?

  2. I can't DRC to the server on 192.168.3.2. The server can (and) accepts connections on a subnet, I created the network of 192.168.6.x I put up as VLAN6 on SEA4 (the port of spare on the map of ether 4 ports). The only thing I did not in the configuration of the interface was the nat ip within the statement.

  3. I can't do a nslookup through the tunnel VPN (delays all the time) and neither can I http to the IIS server on the same 192.168.3.2 box. What I mean here is that other applications seem to work except telnet!)

  Then...:

  Why the telnet is so special? I thought that if I could telnet to the router, then I should be able to access the server. And before ask you, there is no firewall or whatever it is executed on the server by stopping this stupid connections. Hey, I'm the guy from router, not the jockey of server!

  I've managed to misinterpret the statement "corresponds to the address 105" in the cryptomap? The ACL would reflect the traffic flow both ways?

  I should have a statement of hash in the section of "crypto isakmp policy 5. The client indicates that the connection is OK then why should I need it?

  I appreciate your time to help. I was scratching my head a lot in the last two days.

  Timothy

  Your NAT config, it is what kills you here. You can telnet to the router interface, because then the NAT configuration does not take effect (because NAT doesn't happen for passing traffic THROUGH the router, FOR her). You must refuse the IPSec traffic to be NAT would have, otherwise, it does not match the encryption access list and is not encrypted on the way back.

  Your 100 access list is incorrect, remove it and add in the following:

  access-list 100 deny ip 192.168.0.0 0.0.255.255 192.168.5.0 0.0.0.255

  access-list 100 permit ip 192.168.0.0 0.0.255.255 everything

  That said NAT VPN traffic does 192.168.5.0, but NAT do it if he goes anywhere else (Internet).

  Also, you seem to have defined a map static encryption for your customer traffic, it is not used and may cause you problems with the list of access-105. Follow these steps to get rid of it and just use the dynamic encryption card:

  no card crypto clientmap 1

  You just need to have dynamic instance map (number 20) crypto left in your config file.

• Question of VPNS and router

  Hello

  I currently have a RV042G in my company.  It works fine, but I was looking for a solution that would allow me to use VPN so that I can tunnel inside and then again connect to the internet via the tunnel.  I want to have a way secure to connect to internet from my laptop while I am travelling and prefer to build my own VPN and do it myself.

  If I understand correctly, the RV042G does not allow this and it only access to the local network via the tunnel. What would be the next router allowing him to fill this purpose?

  Thank you!

  Hi rodman

  These devices work fine, you can also use third-party software not only software from Cisco to use the VPN features. On subscriptions, IAPH supports more special features such link Protect and IP addresses and you can have and buy a subscription in order to add these features to your device, however, if Don t you want what they you don t have to buy.

  Cisco provide one of the best support, it has plenty of support, it is possible via chat, email or telephone, it also provide assistance free of charge for the users of this forum if you don t buy a warranty

  I hope you find this answer useful,

• Question about encryption for a VPN established between two of our sites

  We have two routers Cisco 2951, one at our main location and one at a branch.  An engineer for a local company came and worked all the parameters, including the VPN between the two men.

  For an upcoming exam, the firm wanted to know what kind of security/encryption has been implemented between the two routers.  The engineer is no longer available, so I've went over our configuration files for each of the routers and will have questions about what to tell them (I'll be the first to admit that some of this stuff is over my head).

  I enclose the portions of the configs with "crypto" information he put in place.  If you see something wrong, or need something extra, let me know.

  Thanks in advance!

  That's what you use:

  Phase 1: 3DES, SHA1, PSK, Group2 DH (1024 bits), life time 86400 s

  Phase2: 3DES, SHA1

  Which is today considered legacy crypto, but probably nothing to worry. The crypto-config has always considered that there is "room for improvement"...
