Rule NAT VPN problem
Hello people, I had a lot of trouble trying to solve this problem, but hoping someone here can enlighten me.
I have a remote site that hosts a number of services that we manage remotely with an IPSec VPN connection. When connecting to the site connect us very well and can make most of the actions like RDP and connect to servers for maintenance, but a service fails to connect unless I have add a NAT rule exempt to the configuration of the router (ASA 5505).
Once this rule in place service work, but other services that initially worked work stoppage. In short, this rule must be in place while doing a single task, but then contracted for other tasks. I hope that there is some sort of rule or behavior, I can add to the ASDM configuration makes it so I don't have to manually add this rule whenever I connect.
Here are the details of the rule:
access-list 1 permit line outside_nat0_outbound extended ip 192.168.15.192 255.255.255.192 192.168.15.0 255.255.255.0
NAT (outside) 0 outside_nat0_outbound list access outside tcp udp 0 0 0
When the connection is established without the rule in place the ASDM syslog shows these warnings:
Deny tcp src inside: outside:10.100.32.203/135 dst
The strange thing is 10.100.32.203 is IP internal my host computer. This is not yet the external IP address of the network I connect from. Is it possible a problem with the VPN pool using a subset of the subnet of the VIRTUAL LAN inside? Inside VLAN is 192.168.15.0/24 and the VPN is 192.168.15.200 - 250. I am ready to reconfigure the VPN address pool but need to do remotely, and am unaware of how to do this reconfiguration safely without losing my remote access, since physical access to the router itself is currently very difficult. If more details are needed, I am happy to give them. Hi GrahamB, Yes, the problem with too much running in subnet. There are a lot of private-address available, so please create a new group policy and tunnel-group and fill pool separate to value ip address and remote with it, when the new cluster to solve your problem, can safely remove the old one. I hope this helps. Thank you Rizwan Muhammed. Tags: Cisco Security Bizzare vShield Edge-NAT/VPN problem Post - 5.1 upgrade Hoping someone can shed some light on this issue for us - the TLDR is that NAT rules seem to be causing unexpected behavior on the VPN traffic after a vCloud 1.5 to 5.1 upgrade. Background: We work with a hosting provider to manage our vCloud environment. Quite simple - 2 ESXi hosts, a few NFS data stores. They have recently updated us of 1.5 and 5.1. For most of our committees, we have just one network of vSE/Routed that connects a subnet to a network of "WAN" and pulls a public IP address from a pool. Send us (NAT network address) and leave (firewall) ports (for example port 3389 for RDP) to the virtual machines selected. Most of these networks also have a VPN tunnel from site to site with a physical Firewall through the internet. After the upgrade, we went and converted our rules to match the period of initial and active INVESTIGATION "multiple interfaces" - effectively subtracts to compatibility mode. Everything was going well (even for devices of vSE always in compatibility mode) Question: We first noticed this, when a customer reported that they are unable to access a virtual machine via RDP using it is internal (protected VSE) IP through a VPN tunnel but could access the virtual machine via RDP using its public hostname/IP address. Allow us all traffic between the VPN (firewall has a whole: a rule for VPN traffic). When we connected to troubleshoot (just thinking that the VPN was down), we found that we could connect to any port on the computer through the VPN tunnel except 3389remote virtual. I can ping from the local subnet to the VM troubled on the VAPP network without problem. I was able to connect to other ports that have been opened on the remote virtual machine without problem. I couldn't connect to 3389 through the VPN. We thought he could be isolated, but found the question on each VSE we have: If there were a the DNAT rule to translate the inbound for a particular port, this port would be insensitive when traffic through the VPN tunnel that is meant to be the target of the DNAT rule. Someone has an idea what could be the cause? Looks like it is a problem experienced during the upgrade. These hidden firewall rules will not disappear until the firewall configuration is updated in some way. So go as - upgrade (1) upgrade VCD (2) update VSM (3) to redeploy the entry door to upgrade the edge of the gateway to version 5.1 (4) convert the firewall rules to the new format (where firewall rules have no management interface or traffic) (5) to change the properties of the bridge and the multiple interface mode (6) change the specification of the firewall somehow, that is to add a dummy firewall and remove it, turn off, then turn on the firewall, etc.. Which should cause the deny rule go away Can connect, I see not all network resources. The Vpn Client, worm: 5.0.01, is running on an xp machine. It connects to the network is behind a 6.3 (5) pix501-worm. When the connection is established the remote client gets an address assigned to the pool 192.168.2.10 vpn - 192.168.2.25: The vpn client log shows: Line: 45 18:07:27.898 12/08/09 Sev = Info/4 CM / 0 x 63100034 The virtual card has been activated: IP=192.168.2.10/255.255.255.0 DNS = 0.0.0.0 0.0.0.0 WINS = 0.0.0.0 0.0.0.0 Area = Split = DNS names It is followed by these lines: 46 18:07:27.968 12/08/09 Sev = WARNING/2 CVPND/0xE3400013 AddRoute cannot add a route: code 87 Destination 192.168.1.255 Subnet mask 255.255.255.255 Gateway 192.168.2.1 Interface 192.168.2.10 47 18:07:27.968 12/08/09 Sev = WARNING/2 CM/0xA3100024 Failed to add the route.

I can ping the remote client, on an inside ip behind the same pix When I get the 'route add failure' above, but I cannot ping the computer name. I activated traversal of NAT using the PDM, but when I connect with this option, I get the error that the "remote endpoint is NOT behind a NAT device this end is behind a NAT device" and ping fails. Behind the pix are a few computers with no central server, so I'm failed a WINS server for remote clients. I created the vpn with the wizard. The configuration file is attached. Any suggestion would be appreciated. Kind regards Hugh Hugh, sure you can classify based on the whole conversation, but you don't have to do but be certainly provide assessments. To sum up the shrinking global problems, the main objective was to ensure configuration VPN RA on the PIX501 has been corrected. 1. we have enabled NAT - T on the firewall - even if it wasn't the question, but need it either it should you RA other places - travseral NAT VPN sensitizes the firewall on the other ends NAT devices - here is some good information on NAT - T for reference in the future http://www.Microsoft.com/technet/community/columns/cableguy/cg0802.mspx 2. we fixed the VPN-POOL/28 network as well as the access list and acl to be coherent crypto sheep. Here is a link for future reference with many PIX configuration scenarios http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/prod_configuration_examples_list.html Finally, your only question remaining, we can say is purely isolated with the customer software vpn and MAC machine. You could maybe try a different version of the client in the MAC, or also look at the release notes for the open caveats to avoid cisco cleint managing versions and MAC versions if there are problems. http://www.Cisco.com/en/us/products/sw/secursw/ps2308/prod_release_notes_list.html Concerning I've recently updated to 8.3.2 and I have been informed of these NAT changes, but even after reading the https://supportforums.cisco.com/docs/DOC-12569 I am still unable to rectify the communication network 192.168.100.0 VPN with hosts on 172.16.1.0 and 172.16.9.0. VPN clients connect to the external interface, and I try to ping inside and the demilitarized zone, respectable 172.16.1.0 and 172.16.9.0 hosts.

Networks VPN NAT l2l problem-Dup-HELP! I use a router IOS as a VPN L2L device to connect my site to several different customer locations, some of them use the same internal IP addresses. These VPNS have been working well. I recently added another client to this system and I am now having a problem with the new configuration. With this configuration, I have NAT my internal addresses. NAT works correctly, but it NAT my bad common NAT addresses and therefore do not generate the tunnel. My internal IP 10.10.x.x incorrect NAT pool 10.129.x.x decent NAT pool 10.99.x.x Help... :)) Thank you The problem is simple. You have almost an identical ACL for two guests. As the first NAT rule has been added previously, it comes into play. To resolve this issue, you must set explicit host/subnet destination match instead of 'none' keyword. For example like this: ip access-list extended ME-CRYPTO-ACL permit ip 10.129.40.0 0.0.0.255 host 10.10.131.63 ip access-list extended ME-NAT-ACL permit ip 10.10.10.0 0.0.0.255 host 10.10.131.63 ip access-list extended SA-CRYPTO-ACL permit ip 10.96.21.0 0.0.0.255 host 10.99.2.95 ip access-list extended SA-NAT-ACL permit ip 10.10.10.0 0.0.0.255 host 10.99.2.95 Another solution is more complex and harder to understand (and explain), you can use Virtual models with tunnel-protection for each customer, VRF and NAT for common services. ___ HTH.

I use special NAT to public IPs are mapped on different servers and our monitoring system and it seems to work very well. For each address of individuals using a NAT, I created the following access rules: Allow HTTP WAN1 everything [PA] Allow SSH WAN1 everything [PA] Refuse all WAN1 everything [PA] Allow rules are of a higher priority so my experience with other firewalls suggests that they should be applied first blocks access to all ports and ports HTTP and SSH then would be open. What seems to be the case is very disconcerting, with any rules applied Allow refusal rules are removed completely open all ports. If I move the priority of rule Deny it blocks all ports, as expected. My question is how can I prevent access to all ports except ports HTTP and SSH with the router in NAT mode specific. When an access rule is set on a NAT 1 rule at 1, you want to change the public ip address to the private IP which is mapped to the public ip address. Allow to use HTTP WAN1 everything [private address] Allow SSH WAN1 everything [private address] Refuse all WAN1 everything [private address] ASA VPN Site to Site (WITH the NAT) ICMP problem Hi all!

Try to find what happened. I had the remote end raise the tunnel, as they can ping resources on my side. I am unable to ping 10.90.238.148 through this tunnel. I used to be able to until the interface of K_Inc has been added. The network behind this interface is 10/8. I asked a question earlier in another post and advises him to play opposite road of Cryptography. And who did it. I was able to ping 10.90.238.148 of 192.168.141.10, with the config below. I am at a loss to why I can't all of a sudden. A bit of history, given routes have not changed. By adding the command set opposite road to cryptography, I find myself with a static entry for the 10.90.238.0 network is what fixed it initially so I don't think it's a problem of route. The remote end had an overlap with the 192.168.141.0/24 that is why my side is natted on the 10.40.27.0. None of the nats have changed so if adding the reverse route worked for a day, it should still work.

My guess is that your two static NAT is configured above policy nat you have configured for the VPN? If this is the case, move your above these static NAT NAT policy and you should see the traffic start to flow properly. -- Please note all useful posts Hello I'm working on a customer site and they have a problem with one of their VPN (we have other works well), but it is a major issue and I think it's because we use manual NAT and NAT of the object on the same server for different things. Traffic between indoors and outdoors: It works with a specific manual NAT rule of source from the server 10.10.10.10 object Inside SRC-> DST 10.10.10.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 SNAT
It works with a specific using the NAT on the server of 10.10.10.10 object Remote SRC-> DST 1.1.1.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 <3rd party="" fw="">= VPN =-> 1.1.2.10 1.1.1.10
If we have the manual NAT and NAT object it does anyway. So the question is (as I am new to zip code 8.3 ASA) should not mix the 2 types of NAt and look at configuring it all with manual NAT or NAT object? With the NAT object out it does not work as it is taken in ouside NAT inside all: Dynamic NAT (inside, outside) source no matter what interface (this NAT to 1.1.1.1 then does not match the card encryption for VPN) and I tried a no - nat above that, but that does not work either. Straws and hugging come to mind try to configure a different config. Any pointers in the right direction would be great. Kind regards Z Hello I'm not sure that installing even with the explanation. Each NAT configuration I did for VPN used Section 1 Manual / NAT twice. You have configured the rule by default PAT that you use as Section 1 NAT rule. NAT rules in the new software are divided into 3 sections You should also notice that the Section 1 and Section 3 NAT has "line number" similar to the ACL parameter type. So if you have a default existing PAT rule configured for Section 1 and just add another Section 1 NAT rule without line/order number (VPN NAT) then it will just fall under the existing rule, making the new useless rule. I would advice against the use of the rule by default PAT as Section 1 NAT rule. Finally, this means that you be constantly watch and edit its configuration when you try to configure more specific rules. As a general rule 3 of the Section the PAT above default configuration would be the following NAT (inside, outside) after the automatic termination of dynamic source no matter what interface This would mean that you need to remove the old. That would mean as naturally as the change would temporarily dismantling all the current connections through "inside", "Outside" while you change the NAT rule format. If after this configure a NAT twice to the VPN (wihtout the setting "auto after"), it will be the rule in article 1 while the default PAT will be Section 3. Of course, Section 1 will be matched first. I'm not quite sure of what your setup of the foregoing have understood. You're just source NAT? I guess that the configuration you do is something like this? network of the LAN-REAL object 10.10.10.0 subnet 255.255.255.0 purpose of the MAPPED in LAN network 1.1.1.0 subnet 255.255.255.0 being REMOTE-LAN network 1.1.2.0 subnet 255.255.255.0 NAT static destination of LAN LAN-REAL-MAPPED Shared source (indoor, outdoor) REMOTE - LAN LAN If the network 1.1.1.0/24 is supposed to be one that is connected directly to your "external" to the format interface may need to be anything else. -Jouni Hi all I have some problems with nat/sheep on a pix 515e. the pix is connected to a tunnel of site2site on the external interface. the problem is to ping the vpn tunnel to the hosts of the demilitarized zone.

What I'm trying to Setup is the following, his IP address of a site can reach the beaches on site B and visa versa. Site A Site B 192.168.10.0 172.16.0.0 192.168.20.0 IPSEC tunnel - 172.17.0.0 -. 192.168.30.0 172.18.0.0 I tested with one subnet to another subnet that works. However, when I try to group the objects it fails. As an example I can set up a VPN of 192.168.20.0 to 172.18.0.0 that I can pass the traffic through but its unable to reach other subnets.

Thank you. Andrew, Accroding to your config, each network is behind a different interface of the SAA, so you will need to change the NAT rule for each of them, for example: NAT (DMZ_Zone, outside) 1 static source ad-network-local ad-network-local destination static obj obj-remote control-remote control NAT (DB_Zone, outside) 1 static source local-network-db db-network-local destination static obj obj-remote control-remote control NAT (AD_Zone, outside) 1 static source local-network-dmz dmz LAN destination static obj obj-remote-distance Please review and give it a try. I hope hear from you soon. VPN problem when local lan IP is IP LAN Corp. Hello I'm having a problem to access corporate services when an example of one of our servers IP address matches an IP address of a local host from the local network, accessed from. Is there a way to bypass and or solve this problem? I use split tunnel, I send you all DNS requests through the tunnel and assigning the DNS name. I inherited this network which is a 192.168.0.0/23 with many services on 192.168.1.x that match easily private local lans. Hello Michael, To resolve the overlap, you need hide the remote with a NAT rule network, so that VPN clients point to an address using a NAT on the SAA. Can I know the version of your ASA? Thank you. Portu. VPN problem taking in charge the VRF CSR Hello community, I am currently evaluating CSR at AWS (60 day trial) and already around the usual problems and specialty architecture network AWS design. I can't open a TAC case, because we purchased no license. We will, once this last problem is solved. Current configuration: It works fine - no problems here. All HA tests work as expected. So far, so good. Now, we had to create a VPN connection to a special local location of our society. We should create a policy based VPN location (no support for VPN road based there). It is a two-to-one VPN. Two advisors of the connection to a gateway onPrem. The two tunnels, run the same field of encryption. OnPrem routing is based on the State of the tunnel. We put this tunnel in the VRF door of entry. Routes are injected to the door VRF routing table by VPN process (reverse-way static in crypto map). To get these exported to consumer VRF routes, there is a network statement in door VRF BGP process. Well, this also works fine if we do this only with CSR A. Reachablity is out. CSR B the delivery of the CSR due to taking work supported the VRF VPN. However, if we establish the second CSR B tunnel, there is something strange happens. Tunnel is very well implemented. Traffic through the tunnel at CSR B is accepted and routed to the destination. Created at door VRF on CSR B traffic is routed in its own VPN very well. However, traffic from a VRF client who reached CSR B (traceroute proved that) is not routed through the VPN tunnel, despite the VPN client routing table is to say. CSR A running the same configuration, there is no problem. Only on the CSR B. I don't understand this. If remove us the configuration of the tunnel of CSR and create only tunnel on CSR B, it still does not. I don't understand why, because I did a comparison of config and found no difference. Someone at - it an idea, whats going on? How can I debug this problem? CSR - A: B 172.29.13.176/28 [20/0] via 1.1.119.182 (vrf - default), 3w4d CSR - B: with route (doesn't work is not for the customer VRF) No itinerary (work, because only sent by public transit to the CSR - A) This problem is hard to describe, I would really appriciate discuss with a TAC engineer in a WebEx. Is this possible? Thank you. Hello Tobias,. The problem you describe is going to be outside our CSR platform expertise. Looks like the CSR works well and HA works as well, and now you're trying to find a solution to a problem of network/VPN that you are facing.
