Cisco Firewall :: ASA 5510 DMZ - Videoconferencing Calling
Dec 5, 2012
How to get this VC traffic through this network. I am quite new to ASAs, and I feel I am making a tonne of headway
The setup: The VCS Expressway is currently sitting within the DMZ (ip 172.16.10.10) which is NAT'd to 208.118.125.130. The internal VCS Control is pointed to the the VCS Expressway within the DMZ (as it is designed to do).
I have accessibility from the DMZ to the internal network. And from the DMZ to outside seems works partially (more on that below).
The problem:
Calls signalling is able to get through my network, but not media. IE, the call initiates, but media does not connect. Furthermore, I registered an internal endpoints (10.2.20.118) to the DMZ expressway (172.16.10.10). The registration works fine, but again, when I call to another endpoint (internal GK register endpoint to external GK registered endpoint) the call sets up, but media doesn't establish.
Here is the network topology, and below that is the run config.
ASA Version 8.0(4)

I am working on Videoconferencing solution between two location. locations are now being connected through IPSEC site to site VPN. Since we are having a common internet link for VPN as well other corporate use we have to prioritize the internet bandwidth for Videconferencing. is there any way i can prioritise videoconferencing traffic by ports? following are the configs done on the cisco 2801 router with Version 12.4(15)T10.
!interface FastEthernet0/1description ILL_12Mbpsbandwidth 20480ip address 94.*.*.180 255.255.255.248duplex autospeed autopriority-group 1!

Both of these ISDNs are up, this gives us 4 channels. Someone said they recieved a busy tone when they attempted to dial out. I looked over the system and seen there are two outbound pots dial-peers. Each dial-peer references one of the BRI ports. The preferences are the same on each dial-peer. I think what is happening is that the system is randomly selecting one of the dial-peers due to the preference, even if both channels of the BRI are in use. How does the system know if that port has both channels in use? I've not used ISDN before, so tried to enter the B-channel sub interface and the system (UC500) tells me I cannot do this. I was thinking about adding each channel into a trunk group and then referencing the trunk group in the dial-peer. I can obviously add both BRI's into one trunk group.

Is it possible to connect an analog phone to an FXS port on a CME router and a VoIP phone to a switch connected to said router and have voice connectivity between the phones? Also, is it possible to connect an FXO port on that same CME to a RJ-11 wall jack to connect to the PSTN and be able to call that VoIP phone as well as the analog phone from my cellphone? I'm trying to tie as I read the CCNA Voice OCG.

Found you on Google and prays that the regulars here will take pity on a former Juniper admin. I've got a brand new shop to handle that is all Cisco including CUCM 8.x and I have zero Call Manager experience. How to enable international calling for a single user
[code]...
brief flow/steps for making sure a user can dial international? I figured it was as easy as making sure their DN CSS had the ability to do so, but apparently not.

In CUCME if you do not configure any translation rules and leave the system mainly at default, when a call is routed to the PSTN the CUCME system sends the true calling party ID which would be a users extension number. Is it correct to assume that a CUCM server based system, when too left at the majority of default (without translation rules or stripping etc) that it will send the true calling ID to the gateway?

we have a Cisco 1801 at one of our remote sites that uses an ADSL line for it's primary connection and ISDN as backup. Despite no apparent problems with the ADSL line the ISDN is repeatedly dialling the internet every 2-3 mins during office hours and considerable expense to the customer.

Just recently bought a Linksys E4200 router and it's been rocking so far! I upgraded from a WRT320N. However it seems that calling with SIP (using my Voip Buster account) doesn't work anymore.I don't seem to be able to register with the Voip service. Port is the standard 5060 (if my memory serves me well, I'm not at home now) and I already activated on the router the special tick for Voip ALG calling. Router is upgraded to the latest firmware and it's the V1 router.With all of the above, I still can't connect using SIP to VoiceBuster. It worked like a charm with the WRT320N so it's something with the router?.

I have some tunnels which terminate to my home router. I'm allowing the other ends of the tunnels to use my voice setup. I need to prepend *67 to all called numbers which don't originate from my house. I don't want people calling my home number based on the caller-id number they see when someone across one of the tunnels calls.
So if 5008 calls 212-333-4444 I want it sent to my provider as *672123334444. If 5001 calls a number, I don't want it touched. Can I do this? I can use IOS or CUCM here.

I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).

We were having a discussion of ios firewall vs. asa for smaller clients(less than 50). On using ios firewall(zbf or cbac)and an asa 5505/5510. One of the arguments brought up on using ios firewall on the router is that a router will do an ip sla failover. I have configured a number of isr's for this and i know it works good.

I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.

I have an ASA 5510 in a live environment. Up til a short while ago I could access this via the ASDM and ssh. However I can no longer connect to it via eithier. When I access It via SSH I get a disclaimer saying the following
*** You have entered a restricted zone! Authorized access only!!! Disconnect immediately if you are not authorized user! ***
It then cuts me off.
When I try to access the ASDM I get the following
The firewall is running all its services without a problem and I can ping the device without any issues. Also none of the config (to my knpowledge has been changed). I set up a console session and http server enable is still there with
http 192.168.200.0 255.255.255.0 inside

I have just configured identity firewall on our ASA 5510.I have 3 nodes that authenticates against Active Directory, using the Windows Server 2008 R2 builtin Network Policy Server: A laptop, a stationary PC, and a Android Phone. All 3 nodes are authenticated using the same user/password.
Now, in ASDM -> Monitoring -> Properties -> Identity -> Users, I can see two of the nodes with my user name attached to it, namely the laptop and the stationary PC.But not the Android phone.
Then it dawned on me. To set up the ADAgent properly, you have to apply 2 group policy entries. Unfortunately, those 2 entries are applied to the Computer Configuraton part of the Group Policy.This means that your COMPUTER has to be a member of your domain for USER IDENTITY to work.So my Android phone and other nodes not a member of the AD Machine Store will never be detected by identity rules, and can roam the network free.

I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?

This is my first time to use the Cisco ASA 5500 family. I have a request from a user to create an access rule, to allow all LAN traffic to Destination IP address 165.241.29.17, 165.241.31.254 with Destination TCP port 5060,5061,5070 and UDP port 50000-52399.

We have setup new ip camera system and as per our vendor to access the camera from outside we need to open,TCP ports and in firewall and forward to our camera server.
Let say our public ip address is 207.114.111.22 and our local ip address for the camera is 11.11.1.30. We have cisco asa 5510.

We've in our company a Cisco Asa 5510 v8.4(3), Asdm 6.4(7) and a SSM-CSC-10-K9. The firewall is in transparent mode. I get an exchange 2003 SP2 server behind. When users trying to send mailing lists with many recipients (above 300), the Exchange server didn't send these mails. I'm pretty sure that this problem come from the ASA Firewall, because when I plug my server directly on my Internet Connection, the mailing list is sent. I've search on the web, and disable "ESMTP Inspection", but it didn't work. [code]

I have CISCO 5510 firewall running with IOS ASA821-k8.bin.My company has purchased another ASA5510 with IOS ASA843-k8.bin.We need to run both firewalls in Active/Standby mode.
If I upgrade the IOS of old firewall to ASA843-k8.bin the the running configurations does not work properly.It does not pick the network objects and NAT rules as they are configured with OLD IOS and running.
Or if I restore the configurations of old firewall at New ASA the result is worst. Even firewall with new IOS does not show any Access Rule and NAT rule and does not supprt network objects.

So I loaded the shiny new ASA 9.0(1) on a test/dev cluster of 5510's with the SecPlus license.In 8.4.4 (or maybe 8.4.3?) new password-policy commands were introduced, which allowed for very granular password policies for local users. This appears to be gone in 9.0.1. Is this by design? These commands met certain compliance regulations. EIGRP is supported in multiple context mode now, however the contexts dont appear to form EIGRP neighborships with each other on a shared interface. I did issue the mac-address auto command in system mode if that matters. All contexts do form EIGRP neighborships with a regular IOS device, however routes are still not propegated from CTX1 to CTX2, 3, etc.It's entirely possible I'm doing something wrong, this is my first stab at multiple contexts, or its possible this doesnt work by design?

I have a Cisco ASA 5510 connected to 2 private lans (1 for my HQ pc's{inside} and 1 for the worldwide mpls{outside}) It is also connected to the public internet at interface "public" and my dmz at "dmz" interface. I suspect I have a routing issue because packet-trace yields allow, the nat looks ok and the objects look ok at least to me but I'm the one with the non working config so...Basically this is the desired flow:
1. I need all traffic from the inside to be able to flow to the outside unimpeded as they are both trusted networks. (this is ok right now as I allow everything via access-list 101.)
2. I need any host on the public internet to be able to reach a server on the dmz via the pat which I set up from the "public" interface to the "DMZ" interface. The desired flow would be that the person on the internet types in [URL] and this is directed to the public interface ip which forwards to the webserver object on the dmz. (I cannot get this working any which way)
3. I need the dmz to be able to communicate with another server on the mpls via the "outside" interface when it recieves the request from the public it then checks with this other server on the outside via nat(translating the dmz range into the ip of the outside interface on the firewall)I have a default route that points to the mpls or outside interface for 0.0.0.0 0.0.0.0 via 10.x.x.1 - (and although I'm not sure I suspect this could be conflicting with traffic that needs to be sent to the "public" interface .... meaning that the firewall should dump packets bound for 0.0.0.0 0.0.0.0 to the public interface - 184.x.x.194 but I'm very reluctant to change the default route as this is in production and I'm not sure how it will affect traffic).However, I do suspect that if I changed the route from default to static as such:
route 10.0.0.0 255.0.0.0 10.x.x.1 (this would get all lan and mpls traffic to the mpls gateway) route 0.0.0.0 0.0.0.0 184.x.x.193 (this would send everything else from public to the public internet gateway)I think this is accurate but then I would bypassing my corporate internet proxy which is behind the mpls gateway at 10.x.x.1? Is there a way to get http traffic originating from the lan (10.x.x.x) to use the mpls gateway and http traffic for the dmz to use the public internet gateway at 184.x.x.193. I don't want to start causing a flow problem for the internet nor do I want to bypass my corp internet proxy.Either way I cannot get this to work, eventhough the logic checks out, I cannot get even a ping response when I allow icmp any any for testing. Note: I can ping resources on each network from the firewall, not only it's own ports in the associated network but other resources on those networks as well.

We currently have two ASA 5510 firewalls in two locations. One in each and they don't have a standby pair. Now, I wanted to put them together in one site and replace the other one with ASA5520. Now my question is, I need to know if the ASA5510 hardware are the same type. They are both ASA 5510 but I am wondering why the other firewall is displaying ASA-5510-K8 and the other one is only ASA-5510.

I'm having a problem with an ASA 5510 and software from Manage Engine (Firewall Analyzer). They are saying that sys log 113019 is not getting data over to the server where the firewall analyzer is installed. I'm checking the config and I see it enabled. Why this particular sys log info isn't making it to the reporting software when other data is.
