• With tunnel VPN ASA5505 problem

  The business needs is for a VLAN again on site to go directly back to an internet service to site B.

  Site A and B are connected by a service of WES MB 100.

  A site is a site of campus with about 25 switches. Him become VLAN on the site is for the engineer access only, so they can access their companys remote access service. This VLAN must stay back so there is very little potential of a trade-off on the live network.

  The solution that I just put in place is to place an ASA5505 as the dhcp server for him VLAN become to Site A. All clients on that VLAN become get a 192.168.100.x address. The external interface on the ASA5505 to Site A is put on the live network to allow a site VPN tunnel to be put in place between the ASA5505 and the Internet - an another ASA5505 firewall

  The Site A ASA5505 was put in place with inside and outside interfaces with the same level of security. 192.168.100.x subnet is exempt from NAT. Traffic is configured to transmit via the interfaces with the same level of security and the tunnel of L2L is coming.

  But I can not all connectivity to the internet from any host on the 192.168.100.x VLAN.

  This is made more complex because the external interfaces on both of the ASA are the corporate network...

  The default route to the Site B ASA5505 is 87.xx.xx.1, the ISP router.

  The Site B ASA5505 connects directly to the ISP router.

  Dan

  There are some parts of the configuration that you have published to that surprise me, such as the assignment of the default route on the inside interface. But these things are not at the heart of your problem. I agree that the core of your problem is probably the sheep access list. If I understand your needs, what you need is 192.168.100.0 is not translated by going to meets B, and is translated by going to the Internet. But your translation says access list never 192.168.100.0 since your access list as another destination:

  access-list no. - nat extended ip 192.168.100.0 allow 255.255.255.0 any

  My suggestion is to rewrite this access list and change the destination of the 'all' to be addresses behind B (LAN to B).

• ASA5505 PROBLEM VPN

  Hello

  Seems to me that configurations are for the most part very well. But of course, they may be different from those who has the remote site. We do not know what are the settings on the other site of this connection VPN L2L.

  NAT0 has configuration of a line that is not necessary (line below)

  permit access list extended ip lan - imp 255.255.255.0 inside_nat0_outbound 1.1.1.0 255.255.255.0

  You can use the "package Tracker" on the side of the CLI to check what happens to first traffic

  entry Packet-trace inside tcp 1.1.1.100 12345 192.168.1.100 80

  I guess the address LAN IP is changed for some reason any so replace the IP addresses above with random IP of the LAN and LAN REMOTE if necessary addresses.

  Issue the command above twice. If the second output always stops in VPN Phase DROP then there are a few problems on each side of the connection VPN L2L in configurations.

  You can check the output of the following command after issuing the command "packet - trace" above also to check what is happening in phase 1 of the VPN L2L negotiations

  ISAKMP crypto to show his

  If that runs through then I would start looking for a problem with related configurations "crypto map" configurations.

• ASA easy VPN connection problem

  Hi guys,.

  I configured easy VPN between 5510 and 5505. Every thing seems fine, however, if there is no traffic in the tunnel in the next few hours, I can not initial 5510 5505 (customer) traffic. But if I first traffice 5505, there is no problem.

  Anyone know why?

  Thank you

  Hello

  This is normal behavior, it is part of the easy vpn functionality. The 5505 will act as a remote for the 5510 vpn client. This isn't like a site to site vpn or both ends know the IP address of the remote peer, and so that each peer can initiate the connection, here the 5510 don't know on the network and 5505 IP when it will connect via the easy VPN.

  If you want the tunnel to be put in place at both ends, I would say that you are using a classic site-to-site connection as described here:

  http://www.Cisco.com/en/us/docs/security/ASA/asa80/Getting_started/ASA5505/quick/guide/SITESITE.html

  I hope this helps.

• Œuvres ping for the VPN ASA5505 RDP does not work?

  I have an ASA5505 VPN remote access facility

  I have a server connected directly behind the ASA and I can ping the server without problem.

  The reports being encrypted and decrypted packets VPN client

  However when I try to RDP to the server packages encyrpted keep incrementing but the decrypted packets are not.

  I also do not see all RDP traffic hit the server (checked by ethereal)

  I did a packet trace and it succeeds, but ends with a parody of IP which I believe is correct as is the vpn traffic and not actually be encrypted.

  This is the correction of the RDP session, I'm confused by one ICMP denied on line 2 that I am able to ping the server?

• ASA5505 problem of asymmetric routing? (I think)

  Good evening everyone,

  I'm looking for suggestions for a solutoion I met today... I am installing a new router and firewall into an existing network. The router is an Edgewater VOIP router to a cable connection with static IP. The firewall is an ASA5505 (security more). There is a third-party router in the mixture (Cisco 1841) which has a PTP connection goes to another site. I'll try to verbally explain the architecture of the network:

  Unfortunately, the existing network was flattened on a 19 on which I'm not allowed to change so:

  VLAN 1 = data network (they used a large 19)

  VLAN 40 = voice (for VOIP phones)

  Edgewater Port 4 > UNTAG 1, tag 40 > ASA5505 Port 0

  Edgewater Port WAN > Cable Modem

  Edgewater DHCP Server for VLAN 40

  ASA5505 Port 0 > UNTAG 1, tag 40 > router Edgewater

  1 port ASA5505 > UNTAG 1, tag 40 > Cisco 2950 FE0/4 (set manually vlan the native 1 2950 to work)

  2 port ASA5505 > UNTAG 1, tag 40 > Cisco SG300 Gig1

  Voice of ASA5505 route 0.0.0.0 0.0.0.0 VLAN40_IP_OF_EDGEWATER

  ASA5505 data route 0.0.0.0 0.0.0; 0 VLAN1_IP_OF_EDGEWATER

  ASA5505 DHCPD for VLAN 1 (small subnet, the rest is ready for static with a gateway from the Cisco 1841 (infrastructure))

  Cisco 2950 4 > UNTAG 1, tag 40 > ASA5505 Port 1

  Cisco 2950 GIg1 > UNTAG 1, tag 40 > Cisco 2950 B

  DG of Cisco 2950 a = IP of Cisco 1841

  Cisco 2950 B Gig1 > UNTAG 1, tag 40 > Gig1 Cisco 2950 (rising MM fiber)

  Cisco 2950 B FE11 > UNTAG 1, tag 40 > Cisco 1841 FE0/0

  Cisco 2950B DG = IP of Cisco 1841

  Cisco 1841 FE0/0 0/0.1 dot1q native 0/0.40 dot1q 40 > FE11 Cisco 2950 B

  Road to Cisco 1841 ip 0.0.0.0 0.0.0.0 firewall VLAN 1 Interface IP (Changed to ip route ip VLAN40_NETWORK VLAN40_IP_OF_EDGEWATER and VLAN1_NETWORK VLAN1_IP_TO_ASA5505)

  Cisco also has internal IP routes through the private point of connection to another site...

  I'm replacing out of their existing connection is a sonicwall firewall and adding a few new POE switches for VOIP phones, VOIP router and an ASA5505. I can't play nice no matter what I tried. It seems that I am running into problems of asymmetric routing (ASA send me some)

  Deny TCP (no relation) on the VLAN 1 static and given dhcp VLAN40 DHCP handed the Edgewater works fine, I can browse on without any problem)...

  I'm not sure what the best approach is to do this. They need to keep the 1841 for now until a connection VPN of STS can be configured with the ASA5505 to their ASA5510 at the other site (months on the road by their budget). All of their PC is statically allocated and using their default gateway as the C1841.

  If you need output all configs I created so far or havy of suggestions on how to solve my problem, I'd love to hear about them. I tried everything short of re - structuring their entire network or deletion of my VOIP router that manages a large number of configurations for VOIP PBX phones.

  Thank you!

  Jon

  Apologies, but this is a very confusing description of how it is configured.  A diagram would probably help.

  If the new VoIP router's DHCP server for vlan 40 where are the customers compared to this?

  You have two lanes on the SAA pointing the VoIP router, what is the reasoning behind this?

  Why are you the ASA to the router VoIP trunking?

  The VoIP router can hand out DHCP addresses for a network, that it is not directly connected or is it why you extended vlan 40 completely out to the VoIP router?

  The router VoIP must give the vlan 40 IPs.

  I guess maybe it's to do with my lack of understanding as to exactly what does a VoIP router (as opposed to a normal router).

  So maybe you could clarify?

• BSOD with VPN Client problem

  I use the VPN Client 5.0.06.0110 to connect to my computer at home at my desk, which has an ASA5505.  If my immediate network to the client PC connection is lost while the VPN is active, I get a BSOD.  There is no problem if my grave DSL or a cable beyond my router is disconnected.  He only (and always) will fail if the network cable to the computer running the VPN Client is cut (or if my router loses power), while the link is connected.

  I am running:

  Windows 7 (all updates installed)

  Pentium Core 2

  4 GB of ram

  Atheros L1 Gigabit 10/100/1000 controller

  Any suggestion would be appreciated.

  BTW, here is the description for your reference:

  PC restarts if physical link is disrupted when a VPN connection

  Symptom: Restart the computer (the user can also see a Blue Screen Of Death (BSOD) before the reboot, based on the setup of the PC) if the physical link is disrupted when a VPN connection (that is when you see the error message "a network cable is unplugged).  This can occur if you run "shutdown" on your PC is connected to the way of the switch, turn off the SOHO router (or switch) the PC is connected to, lose your WiFi connection, or even disconnect the LAN cable to your wired Ethernet port. Conditions: Loss of physical connection during a VPN connection.

• Client VPN connectivity problems

  I use the cisco VPN client to connect to our network, located behind a 515E. The client is authenticated and gets an ip address but cannot ping or connect with one of the hosts. The connection is to a network of customers that is also behind a 515E. I have successfully connected using the same policy to other places and have had no problem. What confuses me, is that we have used to have a Netscreen firewall before and he had a netscreen vpn client which connected since their network with a problem. Is that something they need for their firewall so that we can get through the traffic?

  Try to turn on NAT - T on your pix, by setting up:

  ISAKMP nat-traversal 20

  and configure the client vpn accordingly:

• VPN Client problem

  A remote user on our network has problems with the Cisco VPN. They are using Win XP, Cisco Client 3.5.2 and connect via a router of Compaq Ipaq into a modem cable. When they VPN in our 3000 VPN concentrator works very well. When they try to VPN in the PIX on our network, it indicates that the client is no longer. If they use a Microsoft VPN to connect to the network with the 3000 (we run both MS and Cisco VPN) with it set to use the remote control, the default gateway, the Cisco VPN will connect to the PIX, see the network behind PIX, ping stuff behind the PIX, but not map a drive. The remote user can ping the PIX of their unVPNed in the remote location. No other user is a problem connecting to the PIX (except those with the bad remote access or broadband satellite which cannot VPN into anything anyway). We have even a few AOLer connect to it. Help me please.

  If the compaq ipaq router makes a PAT, that might be the problem. PIX is unable to manage the ipsec clients who crossed pat. The vpn3000 has some mechanism to deal with this. PPTP is different to ipsec.

  You must ensure that the ipsec client has its own public routable ip address.

• VPN Tunnel problem. external interface has private IP

  Hi all

  I don't know if it is wired or not!

  When our ISP provide us an Internet connection our real IP is configured on the ethernet interface, while the serial interfaces have a private IP address.

  The problem here is when I'm trying to configure a VPN tunnel to another router.

  Anything in the configuration is smooth, except for the part where I put the serial interface is my outside.

  The tunnel is still low coz the IP address will be my private (serial interface) during the configuration on the router counterpart is my public IP address.

  So I am woundering is there a way I can force the VPN tunnel to take the IP address configured on the side LAN? Or any other work around?

• ASA 5505 ASDM VPN connection problem

  Hello

  We are running a version of firewall ASA 5505 8.4 (4) 1. The ASDM version is 6.4 (9).

  The problem is when the creation of remote access VPN connection, it works fine for about 2-3 days.

  After that, the VPN client cannot connect more and gives the error code 789.

  In this case, the VPN clients are clients of Windows 7 from different remote networks with the same problem scenario.

  Windows 8.1 clients cannot connect at all and show the same error code...

  All connections go through the keys defaultragroup and preshare match on both sides.

  When the user to connect attemps I receive the following text in the log of the ASDM:

  6 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, P1 retransmit msg sent to the WSF MM
   
  5 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, in double Phase 1 detected package.  Retransmit the last packet.
   
  5 April 10, 2015 10:53:03 IP = 5.240.31.116, encrypted packet received with any HIS correspondent, drop
   
  When I implemented the remote login through ASDM I followed the instructions according to the following link:

  The steps were a little different, but almost the same, given that these instructions show an old version
   
  I'm interested in trying the steps according to this link but not sure this will help me solve the problem id:

  Hello

  If you use local authentication (user name and password on the SAA), so why you would need this threshold?

  tunnel-group DefaultRAGroup ppp-attributes
  No chap authentication
  ms-chap-v2 authentication
  !

  Remove it and try.
