Customer remote VPN cannot ping certain IP
My Cisco VPN client can establish the tunnel with my successful ASA5505 Office vpn but cannot ping some IP such as an internal server (10.100.194.6).
FIREWALL-1 # ping 10.100.194.6
Type to abort escape sequence.
Send 5, echoes ICMP 100 bytes to 10.100.194.6, wait time is 2 seconds:
!!!!!
Success rate is 100 per cent (5/5), round-trip min/avg/max = 1/1/1 ms
Why I can't ping certain IP?
Help, please.
Thank you.
Hey Kevin,
Check out the capture, it is obvious that there is a problem of internal routing as we can see packets from the VPN client requests, but there is no response from the server package.
Please ensure that the server has pointing on the Firewall VPN subnet route.
HTH.
Kind regards
Dinesh Moudgil

Hello
I would like to change the current reserve of VPN to something overlapping to the LAN.
You're also missing NAT0 for the VPN Client connection that is your problem more likely.
You can try these changes

You can also change your settings for encryption for anything other than a. You can use AES.
Hope this helps

Peer AnyConnect VPN cannot ping, RDP each other
I have an ASA5505 running ASA 8.3 (1) and ASDM 7.1 (1). I have a remote access VPN set up and remote access users are able to connect and access to network resources. I can ping the VPN peers between the Remote LAN. My problem counterparts VPN cannot ping (RDP, CDR) between them. Ping a VPN peer of reveals another the following error in the log of the SAA.
Asymmetrical NAT rules matched for flows forward and backward; Connection for icmp outside CBC: 10.10.10.8 outside dst: 10.10.10.9 (type 8, code 0) rejected due to the failure of reverse NAT.

Hello
Seems to me that you can clean the current NAT configuration a bit and make it a little clearer.
I suggest the following changes
network of the VPN-POOL object
10.10.10.0 subnet 255.255.255.0
the object of the LAN network
subnet 192.168.1.0 255.255.255.0
PAT-SOURCE network object-group
object-network 192.168.1.0 255.255.255.0
object-network 10.10.10.0 255.255.255.0
NAT static destination LAN LAN (indoor, outdoor) static source VPN-VPN-POOL
destination VPN VPN-POOL POOL static NAT (outside, outside) 1 static source VPN-VPN-POOL
NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source
The above should allow
- Dynamic PAT for LAN and VPN users
- NAT0 for traffic between the VPN and LAN
- NAT0 for traffic between the VPN users
You can then delete the previous NAT configurations. Naturally, please save the configuration before you make the change, if you want to revert to the original configuration.
no static source nat (inside, everything) all electricity static destination RAVPN RAVPN
No source (indoor, outdoor) nat static static NETWORK_OBJ_10.10.10.0_28 destination NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_10.10.10.0_28
No source (indoor, outdoor) nat static everything all NETWORK_OBJ_10.10.10.0_28 of NETWORK_OBJ_10.10.10.0_28 static destination
No network obj_any object
No network object RAVPN
In case you do not want to change the settings a lot you might be right by adding this
network of the VPN-POOL object
10.10.10.0 subnet 255.255.255.0
destination VPN VPN-POOL POOL static NAT (outside, outside) 1 static source VPN-VPN-POOL
But the other above configurations changes would make NAT configurations currently simpler and clearer to see every goal of "nat" configurations.

ASA VPN cannot ping ip local pool
Hello
We have ASA 5510 a device be deployed for a period of time. Everything works fine except customers local VPN cannot ping local customer VPN which get their IP address to the local swimming pool. They can ping anywhere on the local network of company, but not each other. I don't know there's a logical explantion for this because of an ACL but all appreciated the advice...
Thanks in advance
Keith
Hi Keith,
I think that, in order to allow a customer VPN reach another VPN client, the SAA should turn the VPN traffic (because it will receive the traffic of a VPN tunnel and re - again to send another tunnel.)
Can you add "same-security-traffic intra-interface permits" and try again?
Federico.

Site to Site VPN - cannot ping remote subnet
Hi all.
I have a site to site VPN IPSEC between a 5510 (HQ) and 5505 (Remote). Everything works on the tunnel. Crypto cards and ACL is symmetrical. I see that the tunnel is in place for the required subnets. However, I can not ping of internal subnets inside 5510 to Remote LAN inside 5505 and vice versa. I have other rays VPN 5510 where I can ping within remote LAN successfully x.x.x.x. Can figure out what I'm missing. I can ping internet points, but cannot ping HQ.
Any suggestions?
I'm also an instant learn the ASAs, so I'm not an expert. I know that I encouraged outside ICMP. My statement SHEEP and crypto are running off of the same group of objects that lists subnets of HQ.
Thanks in advance.
5505 lack the command:
management-access inside

VPN - cannot ping the next hop
Then some advice... I have configured a server VPN - pptp on my router, create a vpn for the customer at the site. For the moment, the client computer can connect and a connection to the router. I can ping from client to the router (192.168.5.1) but cannot ping 192.168.5.2 (switch) or 192.168.10.X (workstations)
What I try to achieve is to access the internal network (192.168.10.X), which is the end of the layer 3 switch. Any help/extra eyes would be good.
Here is my design of the network and the config below:
Client computer---> Internet---> (1.1.1.1) Cisco router (192.168.5.1) 881---> switch Dell Powerconnect 6248 (192.168.5.2)--> Workstation (192.168.10.x)

Hi Samuel,.
I went through your configuration and picked up a few problematic lines...
First of all, you can't have your vpn-pool to be in the range of 192.168.10.x/24, because you already have this subnet used behind the switch (this would be possible if you had 192.168.10.x range connected directly to the router). In addition, you may not link your virtual model to the WAN ip address, it must be bound to an interface with a subnet that includes your IP vpn-pool range.
The cleaner for this is,
Create a new interface of back of loop with a new subnet
!
loopback interface 0
192.168.99.1 IP address 255.255.255.0
!
New vpn set up, pool
!
IP local pool defaultpool 192.168.99.200 192.168.99.210
!
Change your template to point the new loopback interface,
!
interface virtual-Template1
IP unnumbered loopback0
encapsulation ppp
peer default ip address pool defaultpool
Ms-chap PPP chap authentication protocol
!
All vpn clients will get an IP address of 192.168.99.200 192.168.99.210 range. And they will be able to get the router and up to the desired range 192.168.10.x/24 behind the router. Packages get the switch, then to the host. Host will respond through the gateway (switch)-> router-> Client.
PS: Sooner, even if your packages arrive at the host, the host will never try to send the response back through the gateway (switch) packets because STI (hosts) point of view, the package came from the same local network, so the host will simply try to "arp" for shippers MAC and eventually will expire)
I hope this helps.

Site to site between ASA 8.2 VPN, cannot ping
Two 8.2 ASA is configured with a VPN tunnel from site to site, as shown in the diagram:
Clients on the inside network to the ASA cannot ping inside, network clients, else the ASA. Why not?
When the rattling from inside network SALMONARM inside network of KAMLOOPS, the following debug logs can be seen on SALMONARM:

Why clients cannot mutually ping on the VPN tunnel?
Hello
Create a NAT0 ACL at both ends.
ex: 10.30.0.0 ip access-list extended SHEEP 255.255.0.0 allow 10.45.0.0 255.255.0.0

Edit: at the beginning, I mentioned ACL #, it may not work.

Customer quick RV042 VPN cannot ping lan network
Hi guys,.
I just created a client2gateway on RV042 IPSec tunnel and use the remote PC quick VPN client tries to connect to this router.
Fast VPN showed that the tunnel has been established. But I couldn't ping the LAN behind the router RV042.
Can someone help me?
Thank you.
Hello
Yes, you are right. To use the fast with RV042 VPN, it is necessary to configure the user name and a password for access to the VPN Client page. As this router does not support VLANs, you can only connect the VPN client to the LAN subnet (you cannot connect the client to any beach IP configured with multiple subnets)
Kind regards

Remote VPN cannot access devices LAN or internet
So I have a server and a computer inside that I can access through an ASA 5505 with ASA 9.2 (1) and ASDM 7.2 (1)
The computer on 192.168.1.110 via port 8080 can show me a demo site.
The server on 192.168.1.222 got my DNS, HTTP, FTP, mail and more about it.
Outside, I got a computer (by outside, I hear from the firewall and the cable directly into the computer) on 192.168.20.2 and firewall outside being 192.168.20.1
From the outside I can access the 8080 without problem (and I guess as well with the server, but it is on another default gateway and are not accessible right now). -When I connect through my VPN I am assigned 192.168.30.5 but unable to connect inside the computer through 192.168.1.110:8080.
This will return the error: asymmetrical NAT rules matched for before and back flow; Connection for udp src outdoors: 192.168.30.5/49608 (...) dst inside: 192.168.1.222/53 refused because of the failure of the path reverse NAT.
Somewhere, I had a conflict or a non-created access rule. Anyone who wants to take a shot?
I marked with "BOLD" for what I thought that may be the cause.

"Nat" bold configuration is incorrect, as you would expect.
Replace it with something like this
the object of the LAN network
subnet 192.168.1.0 255.255.255.0NAT (inside, outside) 1 static source LAN LAN to static destination HOST-VPN-VPN-HOST
I also suggest using a separate access the ACL of the Tunnel from Split 'standard' list.
For example
standard SPLIT-TUNNEL access list permit 192.168.1.0 255.255.255.0
Naturally, you must pass the ACL above to used "group policy" .
In addition, if you want to control the incoming connections to VPN users in 'outside_access_in' ACL, then you could change the default settings on the SAA by running the command
No vpn sysopt connection permit
If you need to return back then just to deliver without 'no' in front. Then back to its default value. This does not show in the running configuration by the way.
With this setting all connections from VPN connections should be allowed on the interface ACL interface that ends the VPN connection. If in your case that would be the ACL attached to the 'outside' interface.
Hope this helps :)

remote VPN cannot access mail server of asa
Hi dear.
I have the router that connect to the asa.
Internet line to connect to the router so all the nat translation is made to the router.
router outside the ip:x.x.xx
router inside the ip:10.0.0.1 interface that is connect to asa outside interface (asa outside ip address: 10.0.0.2)
my mail server to connect to the DMZ asa.
DMZ interface ip address:172.16.10.0./24
mail server IP:172.16.10.10
I'm twice nat for the ip address of the mail server.
1.i do to asa.
static (DMZ, Outside) 10.0.0.10 172.16.10.10
in this mail server ip 172.16.10.10 translation translating 10.0.0.10(10.0.0.10 ip est un sous-réseau de la plage de connexion routeur et asa).
second nat to router.
IP nat inside source static tcp 10.0.0.10 25 25 ext x.x.x.x public ip x.x.x.x
I have no problem with my nat translation to my e-mail server.
I have set up remote client vpn to asa and apply crypto map ASA outside interface which is 10.0.0.2
I do THE static nat router for asa outside ip address.
IP nat inside source static udp 10.0.0.2 x.x.x.x extensible 500 500
IP nat inside source static udp 10.0.0.2 4500 4500 extensible x.x.x.x
I have no problem with the vpn connection. I can connect vpn connection. but I can't access mail server. 172.16.10.10
What can I do in this situation?
I should be writing sheep-access list?
If Yes, how can I write this access list?
Yes, you must configure access on your ASA sheep-list as follows:
IP 172.16.10.0 allow Access-list sheep-dmz 255.255.255.0
NAT 0 access-list sheep-dmz (dmz)

Cannot ping computers on the subnet remote site vpn while to set up
Hi all
I encountered a problem of site to site vpn for ping answered nothing of machines of remote subnet.
the ipsec tunnel is ok but I can ping the ASA distance inside the interface ip
Here is my scenario:
LAN1 - ASA5510 - ASA5505 - LAN2 - ordinateur_distant
LAN1: 192.168.x.0/24
LAN2: 172.25.88.0/24
remote_machine_ip: 172.25.87.30
LAN1 can ping to ASA5505 inside interface (172.25.88.1)
but cannot ping ordinateur_distant (172.25.87.30)
Inside of the interface ASA5505 can ping ordinateur_distant
LAN2 can ASA5510 ping inside the machines on LAN1 and interface
Is there something I missed?
Thanks much for the reply
I don't think it's something you really want to do.
If you PAT the whole subnet to LAN1 ip (192.168.1.0/24) to 172.25.249.1, then LAN2, will not be able to reach the specific host on LAN1, cause now, you represent the LAN1 network, with a single ip address.
So traffic will become a way from LAN1 can reach LAN2 and get the response of LAN2 through the PAT on 172.25.249.1
But LAN2, is no longer specific hosts LAN1 ip traffic, since you only have 172.25.249.1, to represent the subnet to LAN1.
If you still want to PAT the whole subnet to LAN1 (192.168.1.0/24) ip to 172.25.249.1, then you have to do outside the NAT.

some help me
(Q) ping remote ip unable on ASA is not Firewall not on pc (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance
Note - I can ping PC but not the same subnet ip on ASA2 L3
PC---> > ASA1 - ASA2<>
Hi Matt,
Let me answer your question in two points:
- You cannot ping an ASA on another interface other than the one where you are connected to the ASA of.
For example, ASA1 and ASA2 are connected through their interfaces 'outside '. ASA1 (or any other device on the external interface) can not ping/access ASA2 on his (ASA2) within the interface. The only time wherever this can be substituted is a tunnel VPN with the command "access management" configured for other interface, for example management-access inside
- Traffic ASA1 ping to a remote client behind ASA2 won't over the VPN tunnel and as such is not encrypted. That's because ASA1 will forward traffic based on its routing table that probably this way through its 'outside' interface Except that traffic is allowed with the ASA2 (using the ACL), it will fail.
We can do on the routers of sourcing our ping to another interface, but it will not work on the SAA.

You need dynamic nat (for available IP addresses) for the two side to every subset of remote access to the other side remote subnet and so they can access every other subnet as if both from the traffic from your central location.
example:
Say, this IP (10.10.10.254) is unused IP to the central office, allowed to access remote tunnel 'A' and 'B' of the site.

Hi all
I have a client who uses a 506e with the cleint 4.02 for the remote VPN Cisco. The pix is multiple inside roads. The first network inside is 192.168.1.X and E1 of the 506 is 192.168.1.1. The second network is 10.71.56.X.
The problem is as soon as the VPN is connected I can ping any host on the 192.168.1.X, but not anything on the 10.71.56.X network. Without netbios or the other. From the PIX, I can ping hosts on two internal networks.
Here is the config below. Thank you!

You use 10.71.56.0 255.255.255.0 in two places
you route to it via 192.168.1.1, but you're also allocation of addresses for vpn clients. Guests who are on the segment 10.71.56.0/24, if they manage to get the connected vpn client package (which is assigned a 10.71.56.x) address, would not send the response packet to this request on the local subnet, the router that has the 192.168.1.1 interface, which is what would be needed to make it work.
You must use a different network for your vpn clients block - you cannot use the same ip through two different networks space.

Cannot ping sub interface from my remote site VPN gateways
I can't ping my gateways to interface my remote vpn connection sub
I can ping 192.6.1.0 network, but can't ping network 192.6.2.0 or 192.6.3.0
When I remote desktop in 192.6.1.20 I can ping all the networks, including gateways to interface sub.
I think that something in my asa is misconfigured or not added
ASA NAT rules:
Exempt NAT Interface: inside
Source 192.6.0.0/16
Destination 192.6.10.96/27
Static NAT interface: inside (it's for the local NAT of E0/0 out)
Source 192.6.1.1/16
Interface translated outside the Destination: 172.35.221.200
Dynamic NAT interface: inside
Source: no
Destination: outside
ASA access rules:
Permit outside
Source: no
Destination: out
Services: udp, tcp, tcp/http
Static routes:
Interface: Outside > network: all outdoors DSL (shows no DSL in the graph)
Some incorrect configuration:
On the ASA:
(1) directions are incorrect, the default should point to the next hop route, that is to say: the internet router: 172.35.221.x, as follows:
Route outside 0.0.0.0 0.0.0.0 172.35.221.x
---> where x must be the router internet ip address.
existing routes need to be removed:
No route outside 0.0.0.0 0.0.0.0 192.298.47.182 255
No route outside 0.0.0.0 0.0.0.0 172.35.209.81 in tunnel
(2) the following declaration of the static NAT is incorrect too and should be removed:
static (inside, outside) USSLTA01_External USSLTA01 netmask 255.255.255.255
--> You can not NAT interface on the SAA itself.
(3) for the SAA within the interface's subnet mask should be 255.255.255.0, no 255.255.0.0. It should be the same as the router interface subnet mask:
interface Ethernet0/1
nameif inside
security-level 100
IP 192.6.1.254 255.255.255.0
(4) on the way to access these sub interfaces subnet on the SAA as follows:
Route inside 192.6.2.0 255.255.255.0 192.6.1.235
Route inside 192.6.3.0 255.255.255.0 192.6.1.235
Route inside 192.6.4.0 255.255.255.0 192.6.1.235
On the router, configure it by default route as follows:
IP route 0.0.0.0 0.0.0.0 192.6.1.254
