• 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.

• Any bug IOS (ADSL + IPSEC) with Cisco 1721?

  Hello

  I tried to install an IOS image with support ADSL and IPSEC on a Cisco 1721.

  When the router works fine with ADSL, it does not work with IPSEC and vice versa.

  I tried to change the router with a similar 1721, but nothing has changed.

  I tried the following images (I found them with IOS Scheduler) for IPsec:

  C1700-o3sy756i - mz.121 - 3.XP3.bin

  C1700-o3sy756i - mz.121 - 5.YB5.bin

  When I install the versions of IOS, I can't see the ATM interface.

  Have you noticed any IOS bug related to ADSL + IPSEC with the Cisco 1721 versions?

  Thank you

  Paolo

  Hi Paolo

  It comes to the interface card WIC ADSL is not supported in versions of software you tried.

  According to "Software Advisor", the card WIC-1ADSL is supported on the platform of 1721 in the following versions:

  12.2 (13) T, 12.2 (4) AGO, 12.2 (4) 12.2 (4) YH, YJ 12.2 (8), YL 12.2 (8), YM 12.2 (8), YB, YN 12.2 (8)

  So, you will need to get a new image, a crypto of the cause.

• Tunnel of sIte establishing btn two routers cisco 1721

  Hello

  I need to establish IPSec site to site tunnel between cisco 1721 (version supports for IPSec). U can help me to set up the basic configuration.

  The network diagram is standard. The objective of the implementation is to establsih a communication between two end counterparts.

  IE LAN---> router---> Internet--->---> LAN router

  Thanks in advance

  Concerning

• 1721 router + 4esw, WIC + IOS firewall

  Hello

  I have a router (192.168.157.254) Cisco 1721 with a 4port10/100 wic installed.

  Is it possible to filter using IOS Firewall if wic address and lan are similar? I know it's that they have different ip addresses is possible, but if they are in the same LAN?

  For example:

  A server (192.168.157.10) connected directly to the router FILTER wic and using the LAN interface.

  Is possible?

  Best regards

  Yes, the IOS Firewall can filter even if the address LAN and wic are similar. The following link can help you

  How can install and active the new IPS IOS definitions?

  I checked all internal investigations of Cisco TAC and the error messages and I couldn't identify the problem. It does not seem you have a memory problem, you have available 15meg. I try three things and then maybe contact TAC to see if they can help.

  1. download the file again just in case it is damaged.

  2. give your file extension .sdf just in case the name of the file ips_sdf into a problem (shouldn't be).

  3 download the homeless, just in case there is an invalid content in the file that you currently have.

  4. it seems that you have installed to SDM. Try the SDM to install signatures.

  I hope this helps, if not repost or give a TAC guys.

• 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.

  OK, you get it now in your debugging:

  It is an indication that do not match your ray keys. I suggest remove and re-add the key on both devices. When you add it back on the router make sure that you just cut and paste it, cause this can add extra spaces at the end which become part of the key. Enter it manually on both devices and see what you get.

• 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

  Edgar,

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

• Remote SSH connection fall

  Hello

  I have a Cisco 1721 I configured to allow SSH connections in the Internet router on port 2922. For some reason, the SSH connection randomly gets abandoned, most of the time in the middle of typing a command. I don't think it is related to the length of time that I have in the router because I can't rest, usually more than 4 minutes. Any kind of help would be appreciated.

  Thank you

  Brandon

  Hello.. I have my doubts about your static NAT configurations... If you change the access list applied to the ethernet0 (102) and allow ssh (port 22) you can ssh on port 22 of the router E0 IP address Outside... ? .. If the connection is stable and you can then your static NAT might be the cause of the problem.

  I hope this helps... Please, write it down if that is the case!
