Cisco Firewall :: Configuring UC-Proxy On ASA 5505 Version 8.0?
Jan 24, 2012
I'm trying to configure UC-Proxy using an ASA 5505 with software version 8.0.4.I was following the instructions in DOC-5704 and ASA 8.0 CLI.I don't have USB security tokens in UC solution, instead I'm using IP phones Cisco 7961 with MIC.I configure all the items as the documentation says but when I restart the phone outside the Firewall, the 7961 don't registrate with the Call Manager.Checking the troubleshooting I found that it's possible certificates problems but I don't know if I need to do something in phones.
I would like to know if there is any consideration when the UC proxy works just with MIC.The outside phone is a Cisco 7961 configured with static IP address and TFTP address of Call Manager (static NAT in ASA).
Problem: Configuring an auth-proxy redirect on seccessful authentication,Cisco's documentation states that when you are configuring auth-proxy, you may specify a url in which the clients will be redirected to when successfully authenticated.
The command is:,ip admission proxy http success redirect <url-string>,However, the command does not seem to exist on many of the latter IOS versions. I am also unable to find any documentation with alternate methods of sending a redirection to the client after a successful authentication. Is this command depricated? Is there a more efficient method of redirecting?
i have a 5505 running 8.4, and my ISP is giving me a /64 IPv6 Prefix. Basically, I have a subnet between my ASA and my ISP's box which is my outside, running into a private subnet (192.168.0.0), as most of ISP does.I have my ASA behind, and i'd like to turn on IPv6 for my inside hosts, but the problem is that I can't modify the routing on y ISP's side, and thus it will assume all host are directly connected in my outside. Thus, I would need some kind of Neighbor Discovery Proxy on the Outside of the ASA. Is there such feature ?
I have ASA 5505 with base license. I like to install proxy server in my network.I configured below commands to forward my traffic to proxy server from my ASA.
If there is any configuration that i need to configure.And if possible send me the configuration guide to setup SQUID server. ( Actually it was set up by the 3rd party vendor)
I've got an ASA 5505 running 8.2 configured for solely as an IP phone proxy, it is the default gateway for the cucm box and PRI router, its inside interface is directly attached to the same subnet as all internal phones as well. Calls can be placed from either end, but after call is established, proxy phones does not hear audio from internal or pstn phones. The proxy phone registers with cucm with the remote internal IP of the phone that obviously cannot be reached by corp network.
Debugging from pri router shows the rtp traffic destination is the internal ip address of the proxy phone 192.168.0.50, why is the phone registering with its internal IP 192.168.0.50 rather than its Natted external IP 50.50.50.50 that can be reachable by cucm and other phones?Proxy phone is a 7945, after it registers, I do not see it under sh phone-proxy secure-phones, or sh phone-proxy signaling-sessions while on a call.
I have an ASA 5505 that I am using to connect my contractors to via an inside interface, the outside interface is my private LAN. I have setup on our corporate Proxy server to allow traffic from my outside interface of my ASA to go to the internet without credentials BUT log internet activity. The question is I want to know if the ASA can send that http & https traffic to my proxy server and all other traffic to my default route? I want to be able to send all internet traffic to my proxy server. This will avoid me asking the contractors to place proxy credentials in their browsers.
I need to fullfill the below configuration which is working fine on my actual D-Link Netdefend firewall.
We have a range of IP assign by our ISP : 194.250.47.128/29 194.250.47.129 is the firewall IP and 134 the isp gateway.
We have 4 interfaces - The local user interface: lan =192.168.170.1/24 - The servers interface : dmz =192.168.171.1/24 - The database interface : oracle=192.168.169.1/24 [Code]...
There seems to be a large number of the subject queries in one form or another. Having acquired an asa 5505 and using 8.43 firmware and the ADSM gui for router configuration it has not been an easy transition from other products. I have come to understand embedded NAT objects for basic port forwarding but am at a loss on configuring twice nat or manual nat, not really ever dealing with it before, or in this manner.
What I would like to suggest to the experts, is to include far more ADSM web gui examples and discussion for manual nat. The tools are all there - in the nat rules editing page, the display of the rules pictorially and the packet flow at the bottom of the page (and finally thru packet tracing). What is needed is more on the actual entries on the nat editing pages and the logic and explanation of those entries. In this forum what I would like to see is when there are responses that they include both the CLI recommended entries b AND the associated adsm web gui pics. With good documents for reading and examples in the forum, I think there should be much less confusion allowing more attention to some very complex scenarios. At the very least I and others like me will get better edumecated. I am looking to understand CIsco packet routing through explanations of the web gui entries. In fact, I am learning far more by trying to understand the web gui vice simply copying and entering CLI commands. In terms of documents, for example, there should be a very thorough explanation of the relationship between "Translated Addr:" in the first NAT editing page with "Destination Inteface" in the second Advanced page .I have added the packet tracing jpegs for further context. There is an UNNAT lookup entry (first trace block, out of view on the pic) a concept which is missing in the documentation I've read that needs to be added but it is illuminating in how the router handles traffic. What is also interesting is the fourth jpeg which also shows the flow designation of a packet and its handling internally (new packet or one that is associated with an existing packet (previously identified and put in an appropriate table xlate etc)).
What anyconnect version do I need on a 5505 so i can have people connect via iOS devices? Right now I have "anyconnect-macosx-i386-2.5.1025-k9.pkg" on there, will that work for iOS devices?
I believe this setup does the following. The inside interface and interfaces 4,5,6,and 7 will translate using this line....
global (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224
and if the addresses run out is will start using the ouside interface IP address to translate, so traffic is not disrupted and is based on the line of configuration.....
global (outside) 1 interface
My question, does it do this because of the order of the configuration..
global (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224global (outside) 1 interface
or would it do it that way even if it was like this?
global (outside) 1 interfaceglobal (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224
and if so why?Now let's convert the above configuration to ASA 5505 Version 8.3 or newer.
My question is how does it know to use the outside interface as a backup when the OUTSIDE-NAT-POOL is depleted?Also why do I need to define the INTERNAL-SEGMENTS ? Doesn't the "any" in the (any,outside) take care of that?Also wouldn't the "any" in (any,outside) cover interface 3 or DMZ which could be an issue?
I am configuring a Cisco ASA 5505 firewall.In the office there is 1 x SBS 2008 server and 5 x PCs, all sat behind a Netgear DGN1000 ADSL router.We want to implement a ASA 5505 for added security.I have configured the internal interface of the Cisco ASA 5505 to be 192.168.0.1 - this is connected to local switch. The client PCs use 192.168.0.1 as their default gateway.I have configured the external ASA 5505 interface to be x.x.x.217. [code]Change the current router status from Router/Firewall/Modem to Modem only (Bridge mode). The ASA 5505 has its outside interface connected into one of the LAN ports of the netgear. The lan port has an IP of 192.168.0.254.
I planned to create 5 vlans in my cisco 3560 switch. these 5 vlans needs to have internet and needs to access Site-B.
I will write on dafault route to firewall in my cisco 3560 switch. Is ASA 5505 supports this scenario??? If it is then how to configure ASA 5505 firewall.
I have ASA 5505 with base licence. I configured NATing and VPN(site to site). All are working fine.My ASA is base license so i created 2 VLANS, one is inside and outside.Inside i am using 10.91.40.0/24 serie IP addresses.Below are the new requirements that i need to configre:
1. First 30 IP addresses only needs internet directly.( Servers and Management)
2. If remaining IPs likes to use web then traffic needs to forward one proxy server( where he gives user authentiation)
I've have an ASA 5505 with a inside network vlan1 (192.168.0.0/24) - i've configured an IPsec VPN profile and a VPN network of 192.168.0.50/24. I can through my VPN tunnel access inside hosts on vlan1 - but not ASDM on the ASA (192.168.0.1). Under management i've added the VPN network of 192.168.50.0/24 to have access to ASDM, but still does not work.
I need configuring RDP access to my local server from a remote location on my Cisco ASA 5505 Firewall.I have attempted to configure rdp access but it does not seem to be working for me. How to modify my current configuration to allow this? I need to allow the following IP addresses to have RDP access to my server: [code] The other server shows up as 99.89.69.334 but is working fine.
I already added one server for Static route and RDP but when I try to put in same commands it doesnt allow me to for this new one. My configuration file and what are the commands i need in order to put this through. Also, if there are any bad/conflicting entries. Also I have modified IP information so that its not the ACTUAL ip info for my server/network etc... lol for security reasons of course.Also the bolded lines are the modifications I made but that arent working. [code]
I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone. Apperantly, Cisco went away from static ip address to something like nat (inside,outside) dynamic interface. how to create a static ip address under version 8.4? By the way, I am sharing what my configuration used to look before upgrading.
Showing Your firewall has a version number null which is not supported by ASDM 6.2(5). I received this error when trying to run asdm on my asa 5505. I upgraded image and asdm trying different versions. I used many different versions of java all to no avail.
I have upgraded an ASA 5505 to 9.0(1) as I would like to use ipv6 version of dhcprelay. That said, I am unable to obtain a global unicast address but the link-local address is able to communication with the ISP's gateway/DHCP provider which I hope will allow v6 dhcprelay provide internal clients with IP's from the ISP. Trouble is, unsolicated inbound ICMPv6 messages from the ISP's gateway are being dropped on the way into outside interface.

We have Cisco ASA 5505 with ASDM 5.2 We have one Proxy server in our Local Lab and pointed to Hosted service(Simple Signal)issue is, When our proxy server send register to hosted server, ASA change private IP and post with outside IP and src port as 1063 every time.
Here is debug log on real time monitoring.

I have a problem configuring URL redirect on ACE 30 (Version A4(1.0)).When a user enters IP address or a name of a service [URL], the ACE module should redirect him to the page [URL]. Here is my non-working config:
access-list OUTSIDE line 8 extended permit tcp any any eq https access-list OUTSIDE line 16 extended permit tcp any any eq www access-list OUTSIDE line 24 extended permit icmp any any probe http Test_HTTP_1 port 80 interval 60 passdetect interval 30 passdetect count 2 request method head url /index.html expect status 200 200 open 1 rserver redirect URL_Redirect_01 webhost-redirection [URL] 302 inservicerserver host S1 ip address 10.0.0.2 inservicerserver host S2 ip address 10.0.0.3
[code]....
it works, ACE load balances to rservers. Of course, user must enter full url.With redirection configured, user recieves HTTP url redirect message with correct address [URL], but his browser does not display the page. Even directly entered full url does not display it while redirection is configured.Alternatively, does ACE30 already support url rewrite?
I am trying to configure the dashboards for the pre-defined roles ie) Network Operator, Network Administrator, Helpdesk, etc but I cannot find the document to do this. I am running LMS version 4.1.
The goal is to create users and put them in one of these roles and then they would inherit these dashboards when they log on. Can this be done on LMS ? The doco that I am reading says that each user needs to configure their own dashboard or they can use the public dashboard as a starting point.
I'm getting an "ACL does not match proxy IDs" error that I'm not able to troubleshoot, googled this with a lot of results, tried some; but nothing applied.I have setup 2 tunnels, 1/one from a pix 515e (office) to an ASA 5505 (hosted server) for my guys to access the hosted server2/A second one from the ASA 5505 to my client's firewall so that its equipments can reach the hosted server and from the hosted server reach the equipments.Both tunnels are working fine, my issue comes when I'm trying to join my clients equipments from my office, ie cascading the tunnels.
This is the first time I'm trying to cascade some tunnels, no issues with other vpns I have been building.I'm joining the configuration of the pix and the asa and an extract of the syslogs showing the error, any obvious error I haven't seen!
I have successfully set up a 5505 as a cut-through proxy so that wireless users are required to log in when they open a browser to access the Internet. Is there a way to take them to the original page they requested after the login is complete, rather than having it sit at the screen where it is says they are logged in?
I have been using ASDM on a "Cisco Adaptive Security Appliance Software Version 8.2(5)" for a long time and in order to route packets among the interfaces without NATting the packets, I have always been using the function "Add NAT Exempt Rule" under "Configuration -> Firewall -> NAT Rules". Everything has always been working fine.
Now I am trying to use ASDM on a "Cisco Adaptive Security Appliance Software Version 9.1(1)" and I cannot find how to do the same operation: the "Add NAT Exempt Rule" option is no longer available and the only way to make the traffic passing through seems to be NATting it on the OUTSIDE interface.
where I am mistaking? My goal is to let the traffic passing through from the inside interface to the outside interface without being translated.
Im trying to configure remote access VPN on ASA5505. I configured it as local CA server, installed digital certificate on remote station and everything looks fine as far as i can see. I'm using cisco VPN client 5.0 on remote station. when i initiate VPN session it fails while trying to connect. Looks like im missing some configuration but i cannot figure out what it is. Currently i have firewall configured to use group authentication and everything works fine. I want to switch it to use certificate authentication, and if possible, confiure firewall to use main mode instead of aggressive mode for better security.
I would like to connect devices to my network so that their traffic passes through a proxy running on my computer. I figured the best way to do this is by setting the proxy on my router to the one I am running, but then I would need to have another connection to the computer running the proxy or else there would be an infinite loop ?? something like that. so:
Internet -> router (1) -> my proxy on comp A -> router (2) -> computer B
