In a cisco firewall 5520 how could you take a public wan connection and pass it to another firewall behind the 5520 without using nat. How could you put a single port on the 5520 into transparent or passthrough much like you can on a broadband modem?
View 3 RepliesI am working on IPSec Passthrough on an ASA 5520, with version 8.3, and ASDM 6.3. Currently I have a requirement for users in my internal network (10.10.249.128 / 25) to be able to connect to external IPSec VPN servers.
So I created a network object with 10.10.249.128 / 25, and used dynamic PAT to translate the source ip address to the external internet facing outside interface:
I then added the following rules on the inside-in ACL: However troubleshooting shows that isakmp is passing through the firewall, but esp and ah is not.
For isakmp:
For ESP:Seems like the nat rule is drawing my ESP traffic,

However, the command is not recognized. What am I missing? I've tried executing "channel-group #" on the physical interface and tried creating the port-channel 1st and neither commands exist. I haven't seen it listed anywhere if it is only available after a specific piece of ASA software. If it is the software what version at a minimum I need to upgrade to?

I have a cisco asa 5520. i need to forward telnet to a router on the inside interface. Here is what i have done so far but it doesnt seem to be working.
I have created an access-list that looks like this:
access-list 102 extended permit tcp any host 10.10.60.2 eq telnet
But when do this it still doesnt forward my request to the router at 10.10.60.2 . So just to explain what im trying to do. I use Putty, i am putting the outside interface IP into putty, selecting telnet and opening the session. i need the outside interface to see this request and know to forward port 23 to the router on the inside interface with IP 10.10.60.2. The ASA is running version: asa842-k8.bin
I am trying to correctly configure our ASA 5520 and our Mitel Border Gateway in our DMZ. In the documentation for the Mitel border gateway it wants me to set up 2 external IP's on my ASA one to allow 443 traffice into the MBG, and another for 443 traffic that needs to be forwarded to port 4443 for the MGB in the DMZ. My problem is I don't know how to do this. the MBG only has one IP, and I need to have 2 different URL's mapped to two different external IP's both externally using port 443, and one of them forwarding to 4443 on the DMZ interface.

I have a Meraki Firewall that sits behind my Cisco RV082. The Meraki is setup to run a VPN connection with my server but I am having problems passing the VPN traffic through properly.
I have 2 Uverse Internet Connections that the RV082 using load balancing so that they are shared. I have 10 static IP's.
I am trying to come in on one of my static IP addresses throught the Cisco RV082 to the Meraki and after doing a capture on the meraki it appears that it is starting to receive data to intiate the VPN connection but when it sends data back to the VPN client machine it never makes it.
I have a DIR-655_RevB updated with the latest firmware 2.03NA. I have two VPN devices in my house trying to get to my corporate office: a VPN phone and my laptop with a VPN client, both use IPSec. Either device has no problem making a solid VPN connection separate from each other. Meaning that when my laptop is not connected, I can connect the VPN phone with no problem. And when the VPN phone is disconnected, the laptop also has no problem making a solid and stable VPN connection. So I know the router is configured correctly to let thru VPN traffic for either device. i.e. IPSec is enabled, UDP/TCP Endpoint Filtering are both set to Endpoint Independent (and I've tried every other combo), SPI is disabled.
The problem is that I need to have both devices connected simultaneously, which this router is supposed to handle. If I have the VPN phone connected first, then when I launch the laptop VPN client, the VPN phone gets disconnected. I'm assuming that at this point, all VPN traffic is being tunneled back to the laptop. I cannot re-establish the VPN phone connection until I disconnect the laptop client, at which point the VPN phone "automatically" reconnects (meaning I don't have to reboot it, the VPN traffic just somehoe gets redirected back to this device)

I have a pair of ACE 4710 and I think I have all the failover configured correctly and it all appears to be working. My question is regarding setting QOS on the physical interfaces that are part of my port channel. I have qos trust cos enabled on all the interfaces in my port channel.

View 3 Replies View RelatedI have a cisco 2504 running 7.0.220.0. I am trying to configure Web Auth for External Redirect, Passthrough. I have a page created on an external web server that was taken from the Web Auth Bundle and modified. It is a simple "accept" or "reject" on a Terms and Conditions page. I have a Pre-Auth ACL configured to only allow communication to the server the T&C page resides on.
When I connect to the SSID, the page redirects to the external URL and the the URL shows up in the browser window with all the variable data as a GET on the URL line, but the page never loads. It just hangs. I can copy the the URL data, paste that in once I am on-net, and the page loads just fine.
So, something is happening when the WLC is attempting to proxy-redirect the page back to the client.
I have a guest wireless network setup on a 5508 WLC using 7.2.103.0 firmware.

I would like to disable the HTTPS for the logon screen and I am not sure what steps need to be done for this. I researched and found the command "config network web-auth secureweb disable". I set the command on the 5508 only and rebooted. When I tested I got a blank webpage with "http://1.1.1.1/fs/customwebauth/login.html?switch_url=http://1.1.1.1/login.html" in the address bar and had no way of clicking the accept button to get to the Internet.
Everything works fine again if I enter "config network web-auth secureweb enable" and reboot. Do I need to run the "config network web-auth secureweb disable" command on all the 4402 WLC's that are anchored to the 5508? What could be breaking my login.html page while using only http?

I also create a java script button redirect but it didn't redirect to where I needed to go. It just stuck on the splash page.

The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.

View 1 Replies View RelatedWe are using the newest release of AD Agent (1.0.0.32.1, built 598). The ASA Firewalls 5520 are having the software release 8.4(3)8 installed.When somebody tries to connect thru the Identity based firewalls from a citrix published desktop environment (PDI) the connection is not possible. Checking the ip-of-user mapping on the firewalls (show user-identity ip-of-user USERNAME) mostly doesn't show the mapping of the USERNAME and the PDI the user is logged in. The user-of-ip mapping of the PDIs IP-address shows mostly other users, which then are used to authenticate the acces thru the firewalls.
What is interesting, that on the AD Agent using "adacfg.exe cache list | find /i "USERNAME"" i can't see the PDIs IP-address neither because it is mapped to another user.Is Citrix Published Desktop environment supported to connect thru Identity based Firewalls? How AD Agent, Domain Controllers and Firewalls are working together? On the firewalls with "show user-identity ad-agent we see, the following:
-Authentication Port: udp/1645
-Accounting Port: udp/1646
-ASA Listening Port: udp/3799
Why Cisco does use 1645 and 1646 and not 1812 and 1813?The Listening Port is used for what purpose? we tried the AD Agent modes full- download and on-demand with the same effect.
