Cisco VPN :: Tunnel Between Asa5505 And Fortigate 80c Up But No Traffic
Nov 27, 2011
I have set up an ipsec tunnel between a Cisco ASA 5505 and a Fortigate 80c. The tunnel is set up as I execute pings from inside behind ASA to inside behind FG, however I cannot get connectivity to hosts behind the Fortigate (traffic is allowed through policies configured on the FG). What I noticed in packet tracer is that traffic is dropped at the step 'Vpn lookup' To troubleshoot I have configured a test ('fake') vpn connection through the vpn wizard and get the same result in packet tracer. I run 8.4 software on the ASA and this is part of the relevant config.

I have a number of sites in China, they have decent inter-country connectivity but poor connectivity when going overseas.
We have a single site in China witha dedicated 1:1 leased line that has good conectivity both inside and outside of China.
All the sites in China have ASA5505 firewalls
One of our Citrix farms is hosted in the UK and although the main site with the leased line is fine accessing the farm the other sites are not. I would like to try and tunnel just the citrix connectivity via a VPN to the China head office then use their connection to get out to the farm.
how to tunnel all traffic but not just specific traffic over the VPN.

I have two ASA 5505 on two different locations(main office and remote office) and I need the remote office to be in the same subnet as the main office since they move computers betweend the offices and they have fixed IP addresses on those computers and they have no right to cahnge to dhcp mode when they move to remore office. Is it possible to create like a bridge over the VPN tunnel so it extens the LAN ?

We have a HUB ASA5505 SEC+ with a few other ASA's connected to it via L2L VPN. We have 1 active Static L2L, 1 Active Dynamic L2L, and I'm currently trying to add a Second Static L2L Tunnel.I verified that each WAN Interface can ping each other, and both devices have full internet connectivity. There is no double nat or content filtering going on either. I did notice that my Cisco Remote Access VPN Client won't connect properly through the ASA despite full internet connectivity, but when I connect directly to the modem I was able to connect properly. So apparently the ISP isn't blocking IPSEC traffic AFAIK.
Static2 is currently using a Temporary TAC License since our license is currently awaiting arrival, but a show version output shows that all VPN/3des features are enabled. [code]

Got a problem routing trafic to my L2L tunnel...
Got an ASA5505 Sec+ with ip 10.45.10.1 on inside interface. Firmware 8.3(1). Got another Cisco router (From my ISP) with ip 10.45.10.254 - This one creates an L2L tunnel - To the 10.45.20.0/24 net.
On the 5505 ive got "route inside 10.45.20.0 255.255.255.0 10.45.10.254 1", and trafic is being directed to 10.45.10.254 as it should.
I know cause I can ping everything one the 10.45.20.0/24 net - But thats it... Cant RDP, connect to fileshare... Nothing.
When i test a PC and set it to gateway 10.45.10.254 I can access everything on the remote network. Do I need some NAT command or an access-list? I've setup AnyConnect VPN on the ASA and I can connect to both networks without any problems.

I'm having trouble configuring an ASA5505 on version 8.31 code for an IPSec tunnel. I've done this multiple times on 8.2.5 but can't seem to get my tunnel to even attempt to come up on this ASA. Not sure if it's relevent or not, but this remote ASA has never been used for another VPN tunnel before. When I attempt to ping a host on the other side of my tunnel, I just see the following: 8108# sho crypto isa sa
There are no isakmp sas
My local network is 10.1.1.X/24 and my remote peer network contains 66.37.227.X/24. I've been working on this for the better part of the day and would love to get it resolved.

Just bought myself an ASA5505 to replace a PIX 501, and having transferred over most of the previous config I've managed to get the two IPSEC VPN tunnels working as before.
Unfortunately when I try and SSH to the ASA the connection just resets instantly even when the tunnel is up. It seems as if the ASA is actively refusing the connection, though the log doesn't state this. I had always presumed that traffic over an established IPSEC tunnel was implicitly trusted and not subject to usual access-list rules.
I am unable to SSH to the ASA from the 10.0.0.x range, but I can SSH to a machine on 10.27.0.4 (so I know the tunnel is up and working)
Config (minus irrelevant sensitive information) is attached for reference.
Also - though I'm not sure how relevant it is given the tunnels appear to work - when I enter the line "crypto map meepnet-map interface outside" in config mode the ASA reports "WARNING: The crypto map entry is incomplete!" even though I have supplied the access-list, peer and transform-set variables.

I just joined this company and they already ad a VPN to one of their partners that provides them access to some resources. We have now added a 2nd location but the partner wouldnt allow a 2nd VPN tunnel so the decision was made to give the new location a ASA5505 to tunnel thru the main office to access the resources at the partners site.Using ASDM i believe i was able to setup the tunnel to the main office but there is no resource there to use. Now i'm stuck and i do not know what to do to get to the partner site

Currently, I have in a number of remote sites (with dynamic public address) a C800.On this Cisco, I have a config for initiating an agressive-mode tunnel to a central ASA.relevant part of the config:
---
crypto isakmp policy 10
encr aes
authentication pre-share
group 2
!
crypto isakmp peer address 1.2.3.4
[code].....
Now I need to replace these C800 by ASA5505. But I don't know how to replace the "crypto isakmp peer address" command in ASA.The C800 transmits both the password (abcdefg in my example) and the fqdn (remotesite1 in the example). how to configure the ASA to build the tunnel the way the C800 did?

I have an ASA 5505 with Base license and a vpn client. The scenario is like this: LAN -- ASA 5505 -- ISP DSL Router---( Internet ) -- Home DSL Router --- LAN -- VPN CLient, The ISP DSL Router gets a public IP address and the ASA gets a private IP address (ISP DSL router doing NAT) and I cant reach the internet with no problem from the LAN´s ASA side but I cant make the vpn tunnel connection from the LAN´s Home side so I told the provider to bridge the ISP DSL Router, to the ASA so the ASA could get the public IP but in order to do that the provider told me to do MAC clonning on the ASA 5505 which I did putting the ISP DSL Router MAC on the ASA. Now the ASA gets the public IP on the outside vlan by DHCP but when I try to make the VPN tunnel I just cannt. I can reach the public IP by ping on the ASA and I can see the pings coming in using debug but I just cant make the vpn client work.

inside network----ASA5505========internet===========Remote VPN client.
The ASA has one public IP on its outside interface and using PAT to the internet. It only has two interfaces, inside and outside using vlan. I created a IPSec VPN through CLI. My goal is for the remote client to browse the Internet throught tunnel.
Q1: Is it possible?
Q2: The remote side gets connected and has IP from the pool, with is part of inside network. But it cannot ping anything, including the gateway, which is the inside interface. I debug it, it shows the ASA receives the ping packages, but it doesnt send anything back to the client.

I am trying to setup my very first ASA5505 and I cannot get it to pass traffic from the inside to the outside. I am not using NAT/PAT. Here is what I have done so far.

[Code]....
Then from the asdm I permited everything from inside to go out but I cannot get any traffic through. I can ping the outside if I source the outside interface but not if I source the inside. The logs would not show me anything.
I did a packet tracer and it indicates the implicit deny rule at the end of the access-list is stopping my traffic eventhough I have allow rules above it?
I also checked the box in the asdm to allow traffic to pass without NAT

We are going to be setting up a remote access VPN to a Cisco ASA 5505, once connected to the VPN the internet traffic from the client will then go back out to the internet from the ASA (for web browsing), but Is there anyway to force the traffic through an AV server at the head office site before the traffic goes back out to the internet?

I am trying to configure dual ISP on my ASA5505.I have everything configured and working when eth0/0 is connected, but when I disconnect it, it doesn't route any traffic.The static route for the primary isp is removed and the static route to the backup isp shows up, but no traffic goes in or out. I should note that I'm doing this as a proof of concept so eth0/0 is connected to a router and eth0/1 is connected to another router. [code]

We have an issue where by we connect to various customers and the Cisco IPSEC remote access works fine from our LAN through an ASA5505 to a customer site.We have 1 customer that we have some issues with. We can connect from the LAN through to the customers VPN, authenticate and establish a tunnel but in we cannot pass traffic. When we try from outside of the office on a public internet connection the VPN works fine. What could cause this issue?

I have an ASA-5505. [code] I have an Exchange server on the 10.10.10.0 network. I need to be able to allow Active-Sync and OWA from the Guest WiFi through to the Exchange server on the 10.10.10.0 network. The Guest Wi-Fi uses external DNS so traffic is going out to the Internet and getting an IP address which is of course assigned to the Outside interface abd trying to come back in on that interface.How do I make this do what I need? How do I setup the rules to allow this traffic?

Let me start by saying that I'm just starting to study for CCNA, so the ASA seems to be a bit above me yet. The ASA's we are using is for VPN to our corporate office and only allowing access to our Citrix environment, so no direct internet allowed. We have a person who works in the remote office who has need for a caption telephone that requires direct access to the internet. The phone only supports DHCP, and getting the ASA to do an ARP reservations is proving difficult. For now I wrote an access list to allow it's DHCP address out but it still isn't working. The access list I wrote is:
access-list 101 extended permit ip host xxx.xxx.xxx.124 any log
access-list 101 extended permit ip any any
access-group 101 out interface outside
When I do a show access-list I'm seeing that traffic is hitting the access list as the hit counter has increased. When I do a show conn I'm seeing one of the IP's that the phone should have access to, however the flags are: saA, so I'm assuming they are not getting a response. According to the manufacturer, only outbound connections are needed, no incoming ports required. All traffic is TCP.

I have a working L2L between two locations. Location A and Location B.
Location A: 172.16.16.0/24
Location B: 192.168.0.0/24
I would like to block anything inbound to Location A from Location B that isn't initiated from Location A. The block should be done on the ASA5505 at Location A. Location B uses an ISR G2 router. i.e. Location A can start an SSH session to a server in Location B Location B cannot start an SSH session to a server in Location. .
I tried using a VPN filter on the ASA5505 but it isn't stateful, I cannot pass any traffic when using it.
Config on my ASA:
access-list vpn-traffic extended permit ip 172.16.16.0 255.255.255.0 192.168.0.0 255.255.255.0
access-list block-vpn-to-local extended deny ip 192.168.0.0 255.255.255.0 172.16.16.0
[Code]....
I also have an AnyConnect VPN setup for the ASA5505 and it is running 8.2(5).

Currently I have users that connect with the Cisco VPN client to our PIX 515e. Our corporate network is also directly connected to our partners network, sharing common address space. I want to be able allow our VPN users to connect to certain resources on their network. Since they already have routing for our address space, can I allow the VPN to only NAT traffic to certain destination addresses with a local IP address on our network? That way the partner's network does not have to change any routing since they would see the source address as a local IP on our network.

I have a cisco ASA5505, it runs a wide site to site VPN network and has 4 servers connected to it
10.50.15.4 > fileserver
10.50.15.5 > domain controller (exchange)
10.50.15.6 > terminal server
10.50.15.7 > terminal server
Now yesterday i removed 10.50.15.6 and replaced it with a new terminal server with the same ip address, ever since the ASA is blocking traffic between it and the domain controller (example)
2Oct 27 201214:51:0510600710.50.15.655978DNSDeny inbound UDP from 10.50.15.6/55978 to 10.50.15.5/53 due to DNS Query What has me baffled is the only thing different between today and yesterday is the new server is windows server 2008 and the old one was windows server 2003. The new server has the same LAN ip address as the old one to make the changeover seamless for the users.
why all the sudden my ASA has decided to block the traffic between those machines? all the other machines can talk to it fine just not the domain controller, and seeing that this is a terminal server naturally you can see the problem i face!
this router has worked flawlessly for 2 years now without any config changes and i cant work out why its blocking traffic between those 2 machines.

I've just bought a ASA 5505 to project my LAN. I've already use Cisco router in the past but it's the first time with ASA line.Everythings work except one major point, the return traffic is blocked by the system… I don't really understand how the zone based firewall is supposed to work but it seems OK by default, my LAN side is allowed to talk with the Internet but Internet is not allowed to directly call my LAN. The NAT is setup to use the IP of my outside interface.When I try to ping a public server, the ASA debug log show me that the communication can go out the network, with the good translation, then go back to the ASA from the public server and here, the ASA block it because the communication is not allowed.I've only found two workaround:
-allow inside trafic with static rules, and I say NO ;
-disable the zone based feature by settings all zone to the 0 level…
How I'm supposed to make my state-full firewall work with zone based feature?

I have two attachments that show my basic network layout. I can get from the VPN Cisco Client to Workstation 2 just fine with my current NAT rules in place. I can also get from Workstation 2 to Workstation 3 just fine. But I'm having issues when I try to get from the VPN client to Workstation 3... What would I need to do enable to get to Workstation 3 from the VPN client? IT seems very simple to me (just PAT that traffic as I do the traffic from Workstation 2 to Workstation 3) but that does not work.

I've had a Cisco ASA 5505 firewall connected to a cable modem (Virgin Media, UK) for the past 3 years. In the last 6 months or so I have noticed that the ASA would drop the outside (internet) connection intermittently, usually at least once every 1-2 weeks - the interface still shows as being up but no traffic crosses it, and computers on the inside network abruptly lose internet connectivity. Rebooting the ASA or administratively shutting down the interface and bringing it back up again would cure the problem straight away until the next time it happens.
In the last couple of days however despite nothing having been changed in the configuration the frequency of this connection drop has increased to the point where I would lose access to the internet within an hour of rebooting the ASA. It does not seem to matter whether or not there is traffic currently going out or not, inside computers just appear to suddenly lose internet connectivity.
I have tried the following without success:
1) I completely wiped the configuration (configure factory-default)
2) I changed the port the cable modem was connected to (eth0/0 -> eth0/7, changing switchport vlan accordingly)
I thought perhaps 2) had fixed it but it lasted a whole 2 hours before I woke up this morning to find that none of the internal equipment had internet access despite the fact eth0/7 was showing as up/up in ASA CLI.
This morning I manually set the eth0/7 port to "speed 10" (10Mbps, full duplex). It was previously set to be auto-negotiation (default) on both speed and duplex. As of this post it has managed to keep the outside connection up for 3 hours - but I'm not optimistic that it is fixed.
Interface counters have never shown any collisions, errors, etc - only packets input and output as expected.
Since the problem persisted across ports (eth0/0 -> eth0/7) I'm wondering whether or not the problem could either be faulty memory, or some kind of speed/duplex incompatibility between the cable modem and ASA.

I'm going nuts with this ASA5505. This is a secondary firewall used only in emergencies when the primary Checkpoint failes.
The basics, it has two trusted interfaces, E0/1 and E0/2-6. E0/1, inside2 has 192.168.01/29 and inside is 192.168.200.1/24. I'd like any traffic to be allowed from inside and inside2 to outside and any traffic from the inside interfaces should be routed. No restrictions should apply between the two interfaces.
inside works just fine but no traffic is going out of inside2, not to outside or to inside.
