• Change of SG 200-18 - management - VLAN / telnet/ssh-access?

  Hello

  We have a switch SG200-18 that should be used as a switch of working group in our environment (SW

  Version 1.1.1.8). In collaboration with CLI on big and mid range Cisco gear during the past two decades, I have a hard time to understand what follows on the SG200:

  (o) I want to change the management VLAN by default '1' to the management - VLAN used in our environment. Of course, I created this vlan in SG200-config, however when it comes to assign the management IP and VLAN management interface in the advancement of the corresponding film under "Interface IPv4-> management VLAN" selectable is the default "1". see screenshots (closed)

  So, how to define a management VLAN 1 different?

  (o) how to enable telnet/ssh-access the SG200-18 - I'd be much more comfortable with a CLI environment ;-)

  Thank you very much in advance for your help,.

  Hello Ewald,

  Sx200 series switch does not currently offer a CLI option. Have this feature if the Sx300 and 500 series.

  What about chaning the vlan management, you have two options.

  (1) changes the vlan by default under management VLAN > Default vlan settings. This will change all the ports and the management vlan.

  (2) adds a port as a port untagged in the new VLAN. Once this is done, make sure that something is connected to this port, like a computer. Now you should be able to change the vlan management. (This is done to prevent locking)

• Allow remote access to the VPN Cisco ASDM

  Hello

  I am trying to access asdm Setup for the user remote vpn. Our ASA running version 9.1 (1). ASDM is running version 7.1 (1) 52

  I have apart from the interface within the interface enabled for vpn tunnel and I use 3rd interface (asdm_inf) dedicated to this purpose.

  In the asdm, I enabled the management to asdm_inf interface. In the section ASDM, HTTPS, Telnet, SSH, I also add ASDM/HTTPS(port 444) for asdm_inf, ip_address 0.0.0.0 mask 0.0.0.0.

  However, when I connect to the vpn client and try https://asdm_inf:444, the connection is broken with timeout.

  Where could I go wrong? Any help would be appreciated.

  Thank you

  Hello

  Well, split tunnel is incorrect, you are tunneling to 172.16.66.0/24, while your BFD which you want to manage the ASDM to is 192.168.244.0/24, so the ACL split tunnel should also 192.168.244.0/24 network.

• Limited access to the vpn connection

  We have 3 sites connected with the vpn site-to site cisco Pix 515-525-501. We have also 2 cisco 3005 concentrators vpn for users remote access to the system. I have a remote user that needs to connect to one of our servers in order to manage it. Remote users get internal ip address, once they sign in and they get access to all servers and PCs as if they were at the office. Is it possible to block this specific user and give permission to only to a server?

  Thank you

  Hello

  A much better way to filter traffic is using firewall rules. First, assign a separate group of VPN for your users who need to access that server. Assign a pool to this group.

  Then, go to Configuration-> policy Mgmt-> rules: Add a new rule that will be allor traffic from the pool of the group to that specific server (source is the address of the user, the destination is your server). Create another rule for the return shipping.

  Create a new filter (Configuration-> policy Mgmt-> filter): Add the two rules created earlier.

  Go back to the remote access and then apply the filter itself (you can find the firewall drop-down list in the 'Général' tab) and... VOILA

  Rate if all ok.

  See you soon.

• SSH access to PIX

  Hello

  I have a PIX 515. I set up SSH access to the external interface. But if I access denied with connection error.

  Invalid message type

  I set up a user name with privileg password all. Siftware is Version 6.2.

  Access with PDM works very well.

  someone an idea?

  Thank you

  First of all you have todo the foillowing

  hostname XXXXXXXX

  Domain XXXXXXXX

  passwd XXXXXXX (this is the password used to authenticate Telnet / SSH)

  Then, you create a pair of RSA keys

  CA generates the key rsa 512 (check this command you can have fun with levels of encryption, that is to say 512 or 1204)

  Allow ssh hosts/networks to your PIX

  SSH #ip address or network # #subnet mask # #interface #.

  FOR EXAMPLE

  If my external IP address my 1.1.1.1 and I needed to access your pix, you will need to enter the following command

  SSH 1.1.1.1 255.255.255.255 outside

  If you get the prompt for a user name try pix, I use software very good LSVCCs of terminal.

• The VPN client VPN connection behind other PIX PIX

  I have the following problem:

  I wanted to establish the VPN connection the client VPN to PIX on GPRS / 3G, but I didn t have a bit of luck with PIX IOS version 6.2 (2).

  So I upgraded PIX to 6.3 (4) to use NAT - T and VPN client to version 4.0.5

  I have configured PIX with NAT-T(isakmp nat-traversal 20), but I still had a chance, he would not go through the 1st phase. As soon as I took nat-traversal isakmp off he started working, and we can connect to our servers.

  Now, I want to connect to the VPN client behind PIX to our customer PIX network. VPN connection implements without problem, but we can not access the servers. If I configure NAT - T on the two PIX, or only on the customer PIX or only on our PIX, no VPN connection at all.

  If I have to connect VPN client behind PIX to the customer's network and you try to PING DNS server for example, on our PIX, I have following error:

  305006: failed to create of portmap for domestic 50 CBC protocol translation: dst outside:194.x.x.x 10.10.1.x

  194.x.x.x is our customer s address IP PIX

  I understand that somewhere access list is missing, but I can not understand.

  Of course, I can configure VPN site to site, but we have few customers and take us over their servers, so it'd just connect behind PIX VPN and client connection s server, instead of the first dial-in and then establish a VPN connection.

  Can you please help me?

  Thank you in advan

  The following is extracted from ASK THE DISCUSSION FORUM of EXPERTS with Glenn Fullage of Cisco.

  I've cut and pasted here for you to read, I think that the problem mentioned below:

  Question:

  Hi Glenn,.

  Following is possible?

  I have the vpn client on my PC, my LAN is protected by a pix. I can launch the vpn client to connect to remote pix. Authenticates the vpn client and the remote pix makes my PC with the assigned ip appropriate to its pool of ip address.

  The problem that I am facing is that I can not anything across the pix remote ping from my PC which is behind my pix. Can you please guide me what I have to do to make this work, if it is possible?

  My PC has a static ip address assigned with the default gateway appropriate pointing to my s pix inside interface.

  Thank you very much for any help provided in advance.

  Response from Glenn:

  First of all, make sure that the VPN connection works correctly when the remote PC is NOT behind a PIX. If that works fine, but then breaks when put behind a PIX, it is probably that the PIX is PAT, which usually breaks IPSec. Add the following command on your PIX VPN client is behind:

  fixup protocol esp-ike

  See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/df.htm#wp1067379 for more details.

  If it still has issues, you can turn on NAT - T on the remote PIX that ends the VPN, the client and the remote PIX must encapsulate then all IPSec in UDP packets that your PIX will be able to PA correctly. Add the following command on the remote PIX:

  ISAKMP nat-traversal

  See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

  NAT - T is a standard for the encapsulation of the UDP packets inot IETF IPSec packets.

  ESP IPSec (Protocol that use your encrypted data packets) is an IP Protocol, it is located just above IP, rather than being a TCP or UDP protocol. For this reason, it has no TCP/UDP port number.

  A lot of features that make the translation of address of Port (PAT) rely on a single to PAT TCP/UDP source port number ' ing. Because all traffic is PAT would be at the same source address, must be certain uniqueness to each of its sessions, and most devices use the port number TCP/UDP source for this. Because IPSec doesn't have one, many features PAT fail to PAT it properly or at all, and the data transfer fails.

  NAT - T is enabled on both devices of the range, they will determine during the construction of the tunnel there is a PAT/NAT device between them, and if they detect that there is, they automatically encapsulate every IPSec packets in UDP packets with a port number of 4500. Because there is now a port number, PAT devices are able to PAT it correctly and the traffic goes normally.

  Hope that helps.

• The VPN Clients need access to the subnet on another router

  Hello

  We have a pix 515e PIX Version 8.0 (2)

  We have two subnet 10.1.x.x/16 and 10.2.x.x/16

  The firewall is on 10.1.x.x and vpn clients can access this subnet.

  The firewall can ping 10.2.x.y where x is a server in the other subnet.

  On the 10.2.x.x customers out the firewall.

  The problem is that vpn clients cannot access the server of 10.2.x.y even if the pix can ping 10.2.x.y and the road for him.

  What I need to check that the vpn rules are correct in the pix 515e?

  I think it is a rule of exemption nat or something like that not exactly sure.

  Everything would be a great help.

  Thank you

  Hello

  For clients VPN access to these subnets, check the following:

  1 NAT exemption include these subnets (if not using NAT)... it's the NAT0 ACL command

  2. these subnets is included in the split tunneling

  3. these subnets have a route to the PIX to send traffic to the VPN client pool.

  4. There are no ACLs not applied to the inside interface of the PIX deny this communication.

  Now access from branch LAN LAN of HQ each other.

  I face problems that are
  (1) in the direction of LAN, they can access HQ LAN & resource, but cannot access the internet. I did not configure NAT on the router PH
  (2) can I access internet BRANCH LAN via HQ LAN INTERNET. Where can I access the Internet of general management of the LAN of the PH router directly while access to the VPN to the local network of HQ?
  (3) in the Site of the Directorate, phone hard cannot work but phone on PC can call to Headquarters. Hard IP phone are same in remote network (172.16.1.0/24 ). What's the problem? How can I configure separately?

  Please give advise me how should I do.

  Hello

  (1) in the direction of LAN, they can access HQ LAN & resource, but cannot access the internet. I did not configure NAT on the router PH

  Answer:

  You must configure the NAT and crossed to the ASA HQ so that the VPN branch router provides LAN and u-Turn, access to Internet of the SAA.  You must first seup NAT for the branch on the SAA router subnet, then you must type the command:

  permit same-security-traffic intra-interface

  Here's a great example for VPN client hairpining.

  (2) can I access internet BRANCH LAN via HQ LAN INTERNET. Where can I access the Internet of general management of the LAN of the PH router directly while access to the VPN to the local network of HQ?

  Yes, you can

  (3) in the Site of the Directorate, phone hard cannot work but phone on PC can call to Headquarters. Hard IP phone are same in remote network (172.16.1.0/24 ). What's the problem? How can I configure separately?

  You must change your subnet VLANS to be different from the subnet HQ voice phone IP VOice VLAn, it should be fine.

• Restrict access to the administration to WLC5500

  Hi all
  We have configured all our devices in WLC5500 with a service port interface, which helps us to management and monitoring. Given that in our situation, the management interface is accessible from enterprise networks, this means that desktop clients have the ability to achieve the WLC logon screens.

  Is the only way to restrict access to ports to place an on the management interface access ports, or am I missing a GUI/SSH secret command / button that will allow me to disable or limit the management of devices through the management interface?

  In which case I'll have to use an ACL on the WLC management interface, are there any known issues with denying them access to the ports http, https, telnet, ssh and LWAPs trying to connect?

  Thank you
  Leon

  You have hit it on the nose.  You must have an ACL that blocks the terminals "non-admin" to http/https/telnet/ssh/snmp on the device.  as long as you have the permit ip any at the end of the ACL, you should have no problems, or explicitly allow udp 5246/5247

• Itineraries other nets will be lost when using the vpn client?

  I have a very general question. I intend to implement a security solution for the extranet partners to connect to our intranet using VPN client. IPSec will close on the external interface of the Cisco PIX firewall v6.3.

  Now, my consirn is, I downloaded the vpn client to test but I saw no advance settings to define what network traffic will pass through the IPSec tunnel and which will be routed normally. Is it by default all traffic passing through VPN? Is that what it means if there are other networks using their default route, they will not be able to achieve? (i.e. the Internet).

  Thank you.

  That would depend on how you set up the PIX. You can allow the VPN to your site and access to the Internet at the same time. This is called the split tunneling. It is configurable on the PIX, not the customer.

  This link might help you get started, but I'm sure that there stronger links.

• SRA 4600 - users to limit who can connect to the VPN

  We have a SRA 4600 and wishes to restrict access to the VPN to only a handful of our users active directory.  that is when they visit the Web page for the SRA and try to logon, once that they connection they told you they have VPN access.  That, or else they are simply limited to be able to open a session.

  How we would accomplish this?

  Since you are using AD, you can create local groups on your device and then restrict access to specific ad groups.  The way I work is that a domain has several groups assigned to him, and whenever someone logs in, they show some bookmarks are in the group that they have access to (Yes, it works if you are in more than one group).

  If you don't want people to connect at all, make sure that they are not member of the ad groups that access.

  You can find the setting under user-> groups-> Edit-> ad groups.  This tab appears only if the group is assigned to an AD domain (under portals-> fields).

  NetExtender may be restricted in the same way - just make it is available only for groups you want to have.

• Access PIX using SSH when connected remotely with VPN client

  Hello

  I think that this should be a fairly simple for someone to sort for me - I'm new to PIX configuration If Yes please excuse my stupidity!

  I changed the config on our PIX to allow only access via SSH (rather than via telnet as it was previously configured)

  Now, everything works fine when I'm in the office - I can connect to the PIX using SSH without any problem.

  However, if I work from home and connect to the office using my VPN client (IPSEC tunnel ends on the PIX firewall itself) I find that I can not connect to the PIX.

  I have configured the PIX to access ssh on the office LAN subnet and the client pool of IP addresses used for VPN connections by using the following commands:

  SSH 172.64.10.0 255.255.255.0 inside

  SSH 192.28.161.0 255.255.255.0 inside

  where the 1st line is reference to the office's LAN, which works very well, and the 2nd line denotes the IP address pool configured on the PIX for VPN access.

  Can someone tell me how to fix this? I have the feeling that its something pressing!

  Thank you

• Termination of the client PIX VPN and Internet access from the same interface

  Hello

  VPN remote users connect to PIX (7.2) outside interface, but need to have these clients to access the Internet through the PIX outside interface as well. Need this because PIX IPs is registered and allowed access to some electronic libraries. One way would be to set up a proxy within the network and vpn users have access to the Internet through the proxy, but can it be done without proxy?

  Yes, public internet on a stick
