  This does not happen to config 1. If it's a PIX, I would use the

  No.-config-mode keyword after the No.-xauth on isakmp crypto "key."

  command line. It is not available on IOS IPSEC and I have never

  needed to do before. I am running Cisco IOS 12.2 (5.4) T on a VPN of 1721

  router. The static map seems to work by itself. What I am doing wrong?

  I saw her a couple of times and to be honest have never taken down to an exact cause, although in this case it looks like almost to the point of control request an IP address which is weird. Try the following:

  1. Add "card crypto secure1_in client configuration address to initiate" and see what it does.

  2. try 12.2 (8) code T5 with it, I had a previous user running 12.2 (11) T and we got the same error messages, returning to this level of code it is resolved.

  In addition, you wouldn't need:

  > access-list 110 deny ip 192.168.10.0 0.0.0.255 172.16.30.0 0.0.0.255

  for example, so that you do not NAT client VPN traffic?

• LAN-to-LAN tunnel between VPN 3000 and Cisco 1721

  Hello

  I have a current LAN-to-LAN tunnel configuration between VPN 3000 (3.6) and Cisco 1721 (12.2 (11) T).

  When I use the encryption = authentication and Des-56 = ESP\MD5\HMAC-128 for the IPSec Security Association, everything works fine.

  However, I would like to Turn off encryption for some time getting the speed improvements, so I changed

  Encryption = null esp (in 1721) and to "null" in VPN-3000.

  Now the tunnel is setup but I can spend only ICMP traffic. When I pass the traffic UDP\TCP the message below appears the Cisco 1721

  % C1700_EM-1-ERROR: error in packet-rx: pad size error, id 75, hen offset 0

  Has anyone seen this behavior?

  All those put in place an IPSec Tunnel with only the ESP authentication and NO encryption between VPN-3000 and Cisco 1721?

  Thanx------Naman

  Naman,

  Disable you the vpn Accelerator? "no accel crypto engine. Sure that you can't do with a null module vpn.

• Cannot ping vpn client of 1721 cli on the tunnel endpoint

  I have a 1721 fortunately supporting ipsec vpn client connections. With one small exception, everything works perfectly fine.

  The VPN pool is 10.10.10.1 - 10.10.10.254

  The interface internal f0 is attributed to 192.168.1.254/24.

  In my example:

  Ip address of the VPN client is 10.10.10.5

  The host address of an arbitrary machine on the internal lan is 192.168.1.151

  I am able to ping 192.168.1.151 10.10.10.5

  I'm * not * able to ping 10.10.10.5 192.168.1.254 using the cli on the 1721.

  There is a very good reason to want to solve this problem. I would like to be able to access a tftp server on the client vpn directly from the router in order to download the new startup-config files. Is it possible to get the traffic of vpn-/ tunnel-point endpoint client tftp to travel through the tunnel?

  When you ping from the CLI on the router, the packet will be from the external interface, not the IP address fa0 interface. The VPN client and the router only built a tunnel from the 10.10.10.5 address the 192.168.1.0 network, then the router not cryptera a package that her origin is outside the IP address.

  Try to ping extended to 10.10.10.5 and source of 192.168.1.254 package and see if it works. If it does, you will have also to the source of your TFTP packets from inside interface, you can do with:

  IP tftp source interface fa0

• VPN Throughput on 1721

  I have trying to find max VPN throughput on my 1721 VPN package. I don't finy nothing difinitive. I use the Ethernet interface of the WIC to connect to Congress and other centres, so it is not limited by the line rented in most cases.

  The exact flow of a 860MPC base (1721) Cisco router is based on a number of factors. Encryption/encapsulation type, version of the code, etc.

  3DES IPSec router to router "in the laboratory" with 1400 bytes packets are out 8 MB I think. If your network is not "in the lab" you can expect less (probably much less) than that.

• VPN between a router from 1721 to a Juniper srx 240

  Hello

  Is it possible to set up a vpn tunnel on a 1721 router that uses the following ios:

  C1700-y7 - mz.124 - 13b .bin

  I thought I had read somewhere that the tunnels were not supported in the 1700s, but wanted to make sure. If they are I would like to know if they are supported in ios preceding.

  Thank you.

  Yes, 1721 supports the termination of VPN tunnels and you need IP/firewall and IPSec 56 or sets features IOS IP/firewall and IPSec 3DES.

  Here is the Cisco1721 router for your reference data sheet:

  http://www.Cisco.com/en/us/products/HW/routers/ps221/products_data_sheet09186a00800920ec.html

  However, please note that Cisco1721 has reached EOL:

  http://www.Cisco.com/en/us/prod/collateral/routers/ps221/prod_end-of-life_notice0900aecd8044473f.html

  In addition, the current ios you have: c1700-y7 - mz.124 - 13b .bin does not support IPSec. You need to download IOS with IP/firewall and IPSec 56 OR / IP/firewall and IPSec 3DES IOS feature sets to support IPSec.

  I hope this helps.

• Problem with PIX 501-> L2L 1721 VPN

  I am setting up a site to site vpn according to the http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a008051a69a.shtml.

  I want to connect 192.168.105.0/24 and 192.168.106.0/24.

  PIX01 is 192.168.106.1, with dynamic external IP (B.B.B.B)

  RTR01 is 192.168.105.1, with dynamic external IP address (I'm just using DHCP current address of the ISP as A.A.A.A in the config of PIX01 - this is a temporary application, not critical where I can update the address if necessary)

  It seems that the VPN tunnel is established but traffic does not return the router to the pix.  I temporarily hosted all of the traffic on indoor/outdoor PIX interfaces (and icmp).

  If I enable icmp debug I see ping requests from the client to 192.168.106.100 internal interface of the router (192.168.105.1), but no return icmp:

  On PIX01:

  ISAKMP uses UDP/500 and it is true he helped through phase 1 being upwards (QM_IDLE).

  IPSec uses ESP or UDP/4500, and this is what must be authorized by the FW.

• Routing problem between the VPN Client and the router's Ethernet device

  Hello

  I have a Cisco 1721 in a test environment.

  A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

  The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

  The configuration was inspired form the sample Configuration

  "Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

  and the output of the ConfigMaker configuration.

  Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

  side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

  Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

  (customer has a correct route and return ICMP packets to the router).

  The question now is:

  How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

  conf of the router is attached - hope that's not too...

  Thanks & cordially

  Thomas,

  Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

• 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.

• VPN works, but cannot access the LAN...

  I have cisco vpn client connection to a 1721 at the office. the client connects and I can access the office LAN but but not the local network. I have the box checked in client vpn to allow access to the local network. Help, please!

  Hi Matt,

  The config looks good. Please make sure that you get a route to 192.168.69.0 255.255.255.0 network only after the connection to the VPN client. Please also correspond to the exit "route print" before and after the connection. One last thing, I hope that the local network is not 192.168.69.0.

  HTH,

  Please rate if this helps,

  Kind regards

• Is there a 64-bit version of the VPN Client for the coming of Vista?

  Is there a 64-bit version of the VPN Client for Vista to come for VPN 3000 series concentrators?

  Hello

  A bit is a tour here.

  According to Cisco:

  Install the VPN Client on a Vista 64 bit Machine will cause an error 1721

  Cisco IPSec Client does not support 64-bit. If the user requires a 64-bit support, upgrade path is to use the Cisco AnyConnect VPN Client instead, that supports 64-bit. Note that the AnyConnect Client supports only SSL VPN (CSCsi26069) connections.

  So if you want to go with 64-bit, you need SSL support on the VPN 3000 series and replace all IPSEC with SSL connections.

  Please rate if this helped.

  Kind regards

• Prevent the fragmentation of vpn

  I've very fragmented with this configuration, and for this reason, the remote sites cannot receive a bandwidth good vpn.

  2821 is the router of the seat and the location remote vpn 1721.

  1721 features a module vpn.

  What can I do?

  Edgar,

  This link is OK - lets do some math:

  IP header - 20-byte

  TCP header - 20 bytes

  IPSEC header - 56 bytes

  Standard LAN NIC MTU = 1500. When a syn tcp connection is launched - the TCP stack will do the following: -.

  If the NIC MTU = 1500, 20 bytes of the TCP header takeaway, Takeaway 20 bytes of the TCP header - announce a MSS of 1460.

  When you turn on PMTUD (enabled by default on all Microsoft OS) all packages have the DF bit set.

  If you negotiate a TCP session, in 1460 with the DF bit is set, the packets arrive ready Firewall/VPN device for encryption...

  but the device must add 56 bytes of encryption to the contents of the package... 1460 + 56 = 1516, but the interface's MTU 1500 right! Ooops!

  If you start using a ping with the DF bit set - it is misleading because an ICMP packet is 20 bytes, with IP info - so the reported MTU willl

  be 1480! not what you are looking for.

  To be sure, I always do the following: -.

  20 bytes of IP header

  20 bytes of TCP header

  28 bytes for the encapsulation of GRE (if I want to use dynamic routing over VPN protocols)

  56 bytes for IPSEC

  Up to present = 1356.

  I always calculate a surcharge if I deal with VOIP: -.

  12-byte RTP

  All totaled = 1344

  I also allow "fudge" so I use 1300 bytes as the MSS to heart... extermely workes fine for me.

• VPN and MTU issues

  Recently, I have set up a 1721 running IOS c1700-k9o3sy7 - mz.122 - 15.T5.bin

  This router terminated a VPN with another router, a 1721 with the exact same version of IOS. This router has initially been connected via a WAN link on eth0 wireless. We moved their on a t1 as the main interface with the wireless as a backup. Then we had to

  -Configure a loopback - its ip address device would end the vpn

  -make the source of the vpn packages come from the loop

  -Configure static routes w / higher administrative distance

  Do all this we tested VPN - they worked. Unplugged at t1 connection and traffic moves on the wireless. We checked the vpn clients could connect. Everything worked ok...

  Except when you move large files between hosts behind fa0 via the vpn to the guests at the bottom. To prove the vpn worked and routing was in place, we could telnet from a host behind fa0 via the vpn to a remote host and you connect... Then, we would try an ftp files more. We could connect to the ftp server BUT once a file transfer started things would hang.

  We opened a Cisco tac case and it turned out that the addition of

  IP tcp adjust-mss 1300

  the interface fa0 fixed all - file transfer worked.

  My question why would be reduced aid package size? The vpn add some packages generals cauing more large packages to remove?

  A clue was here, BUT it's PPPoE - no VPN...

  http://www.Cisco.com/univercd/CC/TD/doc/product/software/ios122/122newft/122tcr/122twr/wftbrda.htm#1064471

  I'm looking to explain why this reduced MTU size worked. I would of never figured this out on my own...

  Here's the running-config, we used. Don't forget that everything worked (switching between WAN, vpn, NAT connectivity link) except the transfer of files and when large amounts of data was pushed over the line as MS-sharing files/printers, emails with attachments (a few hundred k). The only change is a line at the fa0 interface.

• disorders of VPN

  I have a router in 1721 at home and I'm putting in place so that I can vpn inside via the cisco vpn client. I got to where I could successfully vpn, but I could not access all networks inside. All I could do was one of the servers, 172.16.0.10, ping and everything inside of the interfaces of the router. I could not access web pages hosted on any of my servers and I couldn't ping the server to 192.168.1.10. My config my router is attached. I tried checking allow local access in the vpn client transport options. My router is running crypto/ip/fw/ID/ip /... ios 12.3.22

  I'm not very familiar with VPN and only recently got my CCNA.

  I will attach my config in a separate configuration, I had to change some info

  In fact, it should work.

  Try to use the same address pool, or an address of interfaces for all inside for translations from the outside.

  Make sure that you have added a second interface loopback with ip nat configured inside.

  Please attach the full config again otherwise, collaborating with "sh ip nat translation" exit.

  I hope this helps, please note and mark it as resolved if it does.

• Ins easy vpn server address Pool

  Hello

  I have? ve a router cisco 1721 with a single card wic adsl.

  This router gives me nat (dmz servers) and internet connection.

  Now, I need to implement with this router a vpn server that is easy to provide the vpn connection to customers who use the software of cisco vpn client 4.8.

  I followed step by step the instructions to turn on the server but when the wizard tells me an address pool... I do not know.

  The router has 2 addresses fastethernet, 192.168.156.253 and 192.168.158.253 (secondary).

  My LAN works whith 192.168.156.x address.

  What will be the address pool?

  Best regards

  heze54

  Edgar,

  Configure the pool of addresses as something different from these two networks, as I said in my previous post.

  IP local pool vpnpool 192.168.3.1 192.168.3.254

  I hope this helps.

  Thank you
