Cisco VPN :: ASA5505 - Any Way To Force Traffic Through AV Server

Jan 29, 2012

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?

Cisco VPN :: ASA5505 / WebVPN - RDP Plugin Cannot Force Java Client

Jun 22, 2010

I have just configured a ASA5505 running 8.2.2 as a webvpn server for clientless VPN connections.
 
I need to setup a particular bookmark for a RDP session which forces the use of the java client for those who can't seem to get the ActiveX control working for some reason or another (virus scanners/firewalls/scerutiy policies etc).
 
I created a bookmark as follows, but it always tries to connect with the ActiveX control first when logging on from an IE client.

Cisco :: Force GRE Traffic To/from A Loopback?

Oct 29, 2012

I have a setup with a few sites that have layer three switches behind firewalls. I've been successful in setting up GRE tunnels between all the layer three switches, the GRE traverses IPsec which goes between the firewalls at each site. That way, the GRE is encrypted over the Internet and I don't have to deal with protocol forwarding and stuff. The GRE tunnels are terminated at the loopback addresses of each layer three switch, this works well for the most part, except that I need to put static routes for each loopback address in each switch to point via the firewalls, because when OSPF comes up over the GRE tunnels it starts advertising the loopbacks, and as such the switches think they can get to them over the GRE (which is built from the loopbacks to begin with), as you can see, sort of a catch 22. The static route method works fine, but it makes it so that I can't access the loopback address for monitoring/management purposes from any other sites on the basis that the local core tries to send it directly to the firewall rather than over the GRE tunnel. Is there any way to force only the GRE traffic out via the firewall while letting any other loopback-destined traffic go over the GRE? I'm thinking this could be done with a properly-matching route-map, but I'm not sure where I would apply it, could I apply it directly to the loopback or would the GRE traffic skip that on the way out?

Cisco Routers :: RV220W - How To Force All Traffic From VLAN To Go Through VPN

Nov 21, 2012

Just setup two RV220Ws with a IPsec VPN connection.  All working well.  However, I have a question regarding how to force ALL traffic from a VLAN to go thru the VPN.IPsec from site A (EU) to site B (USA) working good.  On Site A I have a dedicated VLAN that needs to have ALL traffic (internet included) be sent thru the VPN tunnel.  The main purpose of this is to have internet presence as if in the USA.  This is necessary to access some sites available only in USA specially for the kids -their web sites will not display content because they're not in the USA at the moment.  How do I accomplish this?   I tried to setup a Static Route for the VLAN but you cannot setup a 0.0.0.0 destination route.

Cisco VPN :: 871 / 5510 - Any Way To Force Traffic Bound For 192.168.1.x To Go Over VPN Tunnel

Apr 3, 2011

I have 2 Cisco 871 set up to vpn in to an ASA 5510.  Everything has worked even when the 871 is behind a nat.
 
We use these routers to send to employees home for temporary use.
 
The WAN ports on the 871 are configured to pick up an IP via DHCP.
 
Office ASA 5510 - Public IP address
WAN - Public IP
Internal - 192.168.1.0/24
|
Internet
|
Home Router
WAN - Public IP
Internal - 192.168.1.0/24
|
Cisco 871 picks up 192.168.1.x on WAN port from user's home router
Internal vlan1  192.168.10.x/24
 
The problem is - this user's home router is using the same subnet as the internal network at the office.  Is there anyway to force traffic bound for 192.168.1.x to go over the VPN tunnel?  It does this correctly if the 871's WAN port is not also on the same subnet. The vpn tunnel does come up.  And I can ping to and from the router, it's just the clients behind the 871 that cannot ping or access the corp network.

Cisco Firewall :: Force ASA 5520 Traffic Out Specific Interface

Jun 1, 2011

I'm trying to route all default traffic from my production environment through my ASA 5520 on the "outside2" interface.The 5520 has a site to site VPN to our DR site on the "outside/inside" interfaces via one ISP. On another ISP, interfaces "outside2/inside2" go to the internet.
When I make my 3750 stack default route for the inside2 interface IP I cannot get to the internet. When it is pointed to the inside interface on my 5505, I can.
 
I get the following errors when I try to open google.com from a production server:Why is the 5520 trying to use the "outside" interface instead of the "outside2" interface to go out?

Force All Web Traffic Through Separate Linksys WRG54G Router / Gateway For Content Filtering?

Oct 24, 2012

I have two devices: One is a Linksys WRG54G router. The other is a PC running the Smoothwall router software with URL filtering. Either would work fine on its own as a router. I'm wanting to use them both, though, because each offers different features.Right now, the Linksys router is connected to the WAN and is my DHCP server. Its IP is 192.168.0.1. The Smoothwall box has a static IP of 192.168.0.2. I want all web traffic to go through Smoothwall (192.168.0.2) because it offers good web filtering.

I know I could use Smoothwall as my router and rid of the Linksys, but the whole idea behind this is to use the QoS and other features that Linksys firmwares offer (such as Tomato or DD-WRT), but still keep the ability to filter URLs.

Cisco WAN :: C3560E - How To Force DHCP Server To Recycle Unused IPs

Apr 3, 2013

I've configured the DHCP server on a Cisco Switch C3560E as follows:
 
ip dhcp excluded-address 172.16.0.1 172.16.10.255
ip dhcp pool perth_main
   network 172.16.0.0 255.255.0.0
   default-router 172.16.10.254
   lease 0 8
!
 
 My goal was to limit the dhcp to the range 172.16.11.0 - 172.16.13.255, as there are not so many user on this network I so limited the lease time to 8 hours in order to "recycle" the unused addresses". What happend is that it is always using new IPs, even if the lease time has expired.
 
IP address          Client-ID/              Lease expiration        Type
Hardware address/
User name
172.16.109.90       XXXXXXXXXXXX       Apr 04 2013 10:00 PM    Automatic
172.16.113.106      XXXXXXXXXXXX       Apr 04 2013 06:55 PM    Automatic
172.16.113.122      XXXXXXXXXXXX       Apr 04 2013 09:04 PM    Automatic

[code]....

1. How can I force the DHCP server to recycle the unused IPs?

2. Can I specify a DHCP range (172.16.11.0 - 172.16.13.255) instead of an "excluded-address" range?

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.

Cisco Firewall :: ASA5505 Will Not Pass Traffic?

Nov 15, 2011

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.
 
ASA5505(config)# interface Vlan 1ASA5505(config-if)# nameif insideASA5505(config-if)# security-level 100ASA5505(config-if)# ip address 33.46.132.34 255.255.255.248ASA5505(config-if)# no shut

[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

Cisco WAN :: ASA5505 Doesn't Route Any Traffic

Apr 23, 2012

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.

ASA5505 - Tunnel A Specific Traffic Via VPN

May 20, 2012

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.

Cisco Firewall :: Cross Interface Traffic ASA5505

Cisco Firewall :: Allowing Traffic From Inside To Outside ASA5505 7.2(3)

May 15, 2012

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.

Cisco VPN :: Block Unsolicited Inbound Traffic Through L2L On ASA5505

Apr 6, 2013

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).

Cisco Firewall :: ASA5505 - Blocking Internal Traffic Between 2 Servers

Oct 25, 2012

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.

Cisco Firewall :: ASA5505 Return Traffic Is Blocked By System

Jul 23, 2012

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?

Cisco Firewall :: ASA5505 - Outbound Traffic Ceases Even Though Port Is Up

Mar 10, 2011

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.

Cisco Firewall :: ASA5505 - With Two Trusted Interfaces / Traffic Not Going Out Of Inside2?

Nov 14, 2011

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.

Cisco Firewall :: ASA5505 Appears To Be Dropping Traffic For Internal Network?

Jan 10, 2013

we have a Cisco 2901 as a router on a stick for several vlans. Everything on the segment routes fine and accesses the internet just as they should. The 2901 connects to an ASA5505 on port 0/1. Any host connected to the ASA5505 can access the internet, but can not ping into any of the vlans off of the 2901. The strange thing is on either segement of the network I can ping all of the gateways. What is even more strange is when I run wireshark from behind the firewall going into the 2901 I can not see the packet on another wireshark instance behind the 2901. However if I start a ping for a host host behind the asa I can see the packet in wireshark on the host, which I am trying to ping, hit the gateway.

Cisco WAN :: Connecting Remote Node To Server Behind ASA5505

Oct 25, 2012

I have several locations with time clocks (a Kronos application) on a small home network with outgoing traffic wide open.I have a server in my office behind an ASA5505 router/firewall, also with outging traffic wide open. I have tried taking the device off of the remote network and giving the it a public, static ip address so it is actually on the internet, yet the server cannot see the device, but it can ping it. I was advised to put the device on the remote private network and set up a virtual server using port 8080 at the remote location. The server is still unable to see the device. I also set up a virtual server for VNC. When I am on my server on my work network behind the ASA5505, I can start my VNC viewer and attach to the device at the remote site using the IP of the router (apparently the device has a build in VNC server).

I have also tried to NAT my server to a public IP, I have set up incoming and outgoing rules on the firewalls at both ends.this should be a fairly straight forward connection.
