Site to Site VPN of IOS - impossible route after VPN + NAT

• Site to Site VPN NAT conflicts

  I have a site to site vpn between my main office and an office.  Traffic between flow correctly with the exception of some protocols.  My main router has static NAT configured for port 25 and a few others.  For each of these protocols that have a static nat, I can't send the traffic from my office to the IP in the static nat

  either I can't access port 25 on 172.16.1.1 of my office of the branch of the 172.17.1.1, but I have remote desktop access

  It's like my list of NAT is excluding the static entries that follow.  I have posted below the configs.  Any help would be appreciated.

• Client VPN router IOS, and site to site vpn

  Hello

  Im trying to configure a vpn client access to an ios router that already has a vpn site-to site running. I don't see how the two can run on the same router.

  So I guess my question is is it possible? and if anyone has therefore had a config that they can share or a useful link.

  IM using a router 800 series with 12.4 ios

  Thank you very much

  It can be done. Look at this config example that shows a router configured with a site to site VPN and client vpn - connection

• Site to site VPN with router IOS

  I want to create a VPN site-to site on the Internet. On the remote site, aside from the VPN to the head office, there should be no traffic not allowed in internal from the Internet to the network and that there should be no traffic from the internal network to the Internet allowed. The internal network will run a private 192.168.x.x address range.

  I'm going to use a Cisco 2811 router integrated of services on the remote site and this will last an IPSec VPN that will end a hub at Headquarters. I understand that this router has an IOS and IPS firewall built in.

  Would I be right in thinking that because I don't want to have access to the Internet (except VPN) or should I configure IOS firewall features on the router? And there is no point in the configuration of the features IPS wouldn't?

  My thought is that only an entry in list of unique access to deny pi a whole applied inbound to the interface that connects to the Internet would be the best strategy. I think that the command "sysopt connection permit-ipsec" should allow the VPN to form even with the ip address to deny any any ACL (or is it just a Pix command? If Yes, then I have to allow ESP and UDP 500 (ISAKMP) from the public address of the hub at Headquarters to allow the VPN to form wouldn't I?).

  Think I'll probably expand slightly the access list to allow the icmp Protocol, ssh and https traffic from the IP address of firewall seat outside so that I can monitor the remote site and access it safely if the fail VPN.

  And I wouldn't need one access list on the interface connected to the internal network I would like because the range of addresses would be not routable, so they would not be able to initiate connections to the Internet (all the trffic to the remote site is specified under a valuable traffic to bring up the VPN)

  Use one of the IOS Firewall inspect commands or the IPS would be useless and have no effect in this case wouldn't it?

  I really just need to know if the ip address to deny any any ACL on the external interface on the remote site is the best solution (and the simplest), and whether it will be safe.

  We used to use fiewalls Pix for remote VPN site to site, Amazon refuse incoming connections on the external interface by default but now I have been informed that these series 2800 routers will be used later, so I would get my thoughts straight and be able to build safe to do the same work all existing PIX are doing (they are all installed for just the VPN at Headquarters as in) the first paragraph).

  I would like any advice or thoughts on the subject. I don't know there must be a ton of people who put routers for the same purpose.

  Thank you in advance.

  I did a lot of implementations site VPN to another using IOS routers. They work very well. Based on my experience I offer these comments and I hope that they will help you:

  -you don't want a list of incoming access on the external interface, but you want more in it than simply refuse an ip. There is no permit-ipsec sysopt connection in IOS so you want to certainly allowed ISAKMP and IPSec/ESP. I suggest that you also want to allow SSH. I would like to allow ICMP but only starting from the address space of the network head end. I do not allow HTTPS since I generally do not allow the http server on the router. If you want HTTPS then certainly enable it. To facilitate the ping and traceroute on the remote I frequently allow icmp echo-reply, timeout and unreachable port from any source.

  -I want to put an inside interface access list. There are certain types of traffic that I don't want to send from the Remote LAN. I have usually refuse any trap SNMP or snmp for LAN devices and refuse out of the local network icmp redirects. I also often configure RPF controls inside interface to catch any device which is misconfigured.

  -If you want to allow SSH when the VPN is not active (and I highly recommend that you do) then you will probably need to configure at least 1 (and maybe more) users and password of the router ID. And you want to configure authentication on the vty use local authentication if the head end authentication server is not available.

  -I'm not clear from your description if you plan to run a dynamic routing via the VPN Protocol. I wish I had a dynamic routing protocol because I want to announce a default route to the remote control via the VPN. I do not locally configure a default route on the remote router. This way if the VPN tunnel is up there is a default route pointing to the tunnel and if the VPN tunnel is not up then there is no local route by default and users on the remote database can not access the Internet. It is a simple and very effective method to ensure that all user traffic must pass through the central site.

  -regarding the routes defined on the remote router, my approach is that I define a static route for the endpoint of the tunnel to allow the tunnel to implement and I set up static routes for the subnet to the head of line I can SSH. And I do not configure other static routes the on the remote router.

  -You probably want to disable cdp on the external interface and also to disable the proxy-arp (and I don't make any ip unreachable).

  -There is frequently a problem when using VPN site-to-site with fragmentation. If a device on the local network sends a frame of maximum size, and then the router needs to add additional headers for IPSec, then the frame is too large and requires fragmentation. I like to use tcp adjust-mss ip to control the chunk size for TCP traffic and avoid any problems with fragmentation.

  -I don't think you want to set up the firewall or IPS from the features of IOS on the 2811.

  I hope that your application is fine and that my suggestions could be useful.

  [edit] after posting my response, I read through your post again and realize that you make to a VPN concentrator. The approach I have proposed on the execution of a routing protocol works for me because I usually have a router IOS in mind. It would not work to connect to a hub.

• Site to Site VPN Cisco IOS 1941 15.0 (1) M1

  Hello

  I am currently developing a Site VPN site between an ASA and a router in 1941. Configuring VPN on the SAA seems to be ok, because it works without problem with router 1841 with IOS 12.4 to the other site. The same VPN configuration on the new router in 1941 with M1 IOS 15.0 (1) does not work. It seems that the access to the crypto map list is the problem. The router never start the VPN connection. When the ASA attempts to establish the VPN, the debugging of the router log shows:

  ...

• Routing multiple subnets on a site to site VPN

  What is the recommended solution to deliver several subnets on a site to site vpn? Each subnet requires its own policy or a policy can be used for one or more subnets if the remote site has several subnets? In addition, if the remote router has only two fastethernet interfaces, it'll work if one of the interfaces of subinterface configuration or router on a stick?

  If you talk about static routing, you can simply add the routes and change the ACL for encrypted as a result traffic.

  If you want to run a dynamic routing. you will then need to IPSEC VTI.  Here is the link

  http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t14/feature/guide/gtIPSctm.html#wp1063136

  and although I did not use of subinterfaces for IPSEC VTI. but according to me, it will work.

• Is site to site VPN with sufficiently secure router?

  Hello

  I have a question about the site to site VPN with router.

  Internet <> router <> LAN

  If I have a VPN site-to-site configured on the router above with another site. I configured to block incoming Internet connections with the exception of VPN to access list. What are the risks of the LAN is exposed to threats from the Internet? Recommend that you put in a firewall between the router and the LAN, or replace the router with a firewall?

  Thank you

  Hi Amanda,.

  Assuming your L2L looks like this:

  LAN - router - INTERNET - Router_Remote - LAN

  |-------------------------------------------------------------------------------|

  L2L

  Traffic between the two local area networks is protected by the VPN tunnel. It is recommended to use the recommended security (strong encryption settings) to ensure that the encrypted traffic would not be compromised through the Internet.

  On the other hand, if you talk about outbound plaintext to the Internet, as when a user acceses google.com, then you just make out traffic, but never allow all incoming connections.

  If you want to protect your network with advanced security as a FW features, you can consider ZBF, which is the available in IOS Firewall/set function:

  Design of the area Guide of Application and firewall policies

  If you consider that this is not enough, check the ASA5500 series.

  The PIX is also used VPN client, such as the VPN Cicso 5.0 client access, works very well. Router is used as a server SSL VPN, too much work

  I know there are a lot of data here, I hope that these data may be useful for diagnostic purposes.

  All suggestions and tips are greatly appreciated.

• IPsec site to Site VPN on Wi - Fi router

  Hello!

  Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

  I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

  See you soon!

  Michael

  I suspect that.

  Thank you very much for the reply.

  See you soon!

• SA520w routing through site-to-site VPN tunnels

  I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.

  A - the site 10.10.0.0/24

  Site B - 10.0.0.0/24

  Site of the C - 10.25.0.0/24

  Any help is greatly appreciated.

  So, that's what you have configured correctly?

  RTR_A

  ||

  _____________ || ___________

  ||                                            ||

  RTR_B                                RTR_C

  Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.

  Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.

  I hope this helps.

• IPSec site to site VPN cisco VPN client routing problem and

  Hello

  I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.

  The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.

  There are on the shelves, there is no material used cisco - routers DLINK.

  Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.

  Can someone help me please?

  Thank you

  How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.

  Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL

  DE:

  access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255

  TO:

  access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255

  Also change the ACL 190 split tunnel:

  DE:

  access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255

  access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255

  TO:

  access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255

  access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255

  Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.

  Hope that helps.

• A Site VPN PIX501 and CISCO router

  Hello Experts,

  I have an at home test lab, I set up a site to site vpn using a router Cisco PIX501 and CISCO2691, for configurations, I have just a few links on the internet, because my background on VPN configuration is not too good, for the configuration of routers, I followed this link:

  www.Firewall.CX/Cisco-Technical-Knowledgebase/Cisco-Routers/867-Cisco-ro...

  and for configuring pIX I just use the VPN Wizard of pix. All confgurations but ping failed. Hope you can help me with this, don't know what to do here (troubleshooting).

  Joint here is the configuration of my router, topology, as well as the pix configuration. Hope you can help me with this. Thanks in advance.

  Hi Mark,

  I went in the Config of the ASA

  I see that the dispensation of Nat is stil missing there

  Please add the following

  access-list allowed sheep ip 192.168.1.0 255.255.255.0 172.21.1.0 255.255.255.0

• Impossible to get to the beach for additional IP addresses on IPSec Site to Site VPN

  Hello
  I am trying to set up a free IPSec Site to Site VPN between an ASA 5510 (ASA Version 8.2 (3)) to the AC and a Cisco 877 (12.4 (24) T3) to a branch.

  At the end of the branch, I have the 192.168.244.0/24 subnet.
  At the end of HQ, I have the 172.16.0.0/22 and the 10.0.0.0/8 subnets
  The inside interface of the ASA at Headquarters is 172.16.0.15/22

  When installing VPN Wizard I ticked the box NAT - T, and I included the additional subnet in the list of protected LANs.

  I can sucessfully all the subnets 172.16.0.0/22 but not access anything in the 10.0.0.0/8 subnets.
  The Packet Trace ASA tool shows the traffic inside the interface of 172.16.0.0/22 in the direction of 192.168.244.0/24 through the outside interface properly spend, but the 10.0.0.0/8 does not work. He gives no precise information why the 10.0.0.0/8 traffic is dropped.

  [HQ_LAN]---10.0.0.0/8 & 172.16.0.0/22---172.16.0.15(inside_int)-[ASA 5510] - IPSEC-[RTR 877]---192.168.244.0/24---[BRANCH_LAN]

  I suspect it might have something to do with NAT?

  Help, please.

  Hello

  Peer VPN you do not accept the LAN between these two peers of vpn segment.

  On your ASA

  inside_outbound_nat0_acl list of allowed ip extended access all <> 255.255.255.0

  and

  Router:

  access-list 100 permit ip 192.168.244.0 0.0.0.255 172.16.0.0 0.0.3.255

  access-list 100 permit ip 192.168.244.0 0.0.0.255 10.0.0.0 0.255.255.255

  Please make the same statement subnet explicitly between two vpn peers and finally please add this route on SAA.

  Same question on this ACL so, statement of not identical subnet between two peers of vpn, please make sure it identical at both ends.

  outside_cryptomap_2 list extended access allowed object-group ip <> <> 255.255.255.0

  Route outside 192.168.244.0 255.255.255.0 ASA_EXTERNAL_GW

  Let me know the result.

• VPN - PC (vpn client) problem-&gt; router-&gt; (site to site vpn)-&gt; local network

  Hello

  is it possible to install?

  I have a pc and I want to connect to the Remote LAN.

  PC (using vpn client) - vpn (internet)---> ROUTER1 - a vpn (MPLS network)---> ROUTER2---> SERVER site

  How can I connect to a remote server? Is there an easy way?

  I did the configuration of the vpn client (I can connect ROUTER1 and access a LAN via vpn with 192.168.1.x), but I can't connect to the server, even if I set the subnet (192.168.1.x) under the access list of site to site vpn (access list for traffic that must pass between ROUTER1 and ROUTER2).

  Please advise! Thanks in advance.

  Looks like I've not well explained.

  On ROUTER1

  ===================

  1 ACL VNC_acl is used to split tunnel, so you should include IP server_NET it NOT vpn IP pool.

  2 ACL najavorbel is used to set the lan lan traffic between ROUTER1 and ROUTER2, 2 you should inlcude

  IP 192.168.133.0 allow 0.0.0.255 0.0.0.255

  You must change the crypto ROUTER2 ACL of the minor or the najavorbel of the ACL

  The other way to is to the client VPN NAT IP to a local area network lan IP ROUTER1, in this way, you don't need any changes on ROUTER2. But I have to take a look at your configuration to make the suggestion.

• Troubleshooting IPSec Site to Site VPN between ASA and 1841

  Hi all

  in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

  I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

  I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

  It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

  It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

  Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto.      (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

  I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

  It's the running of the 1841 configuration

  Joerg,

  ASA receives not all VPN packages because IOS does not send anything.

  Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

  The problem seems so on the side of the router.

  I think that is a routing problem, but you only have one default gateway (no other channels on the router).

  The ACL 100 is set to encrypt the traffic between the two subnets.

  It seems that the ACL 101 is also bypassing NAT for VPN traffic.

  Follow these steps:

  Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

  I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

  Federico.
