Vlan 200
ip add 2.2.2.2
i want to make communication between 2 vlans on firewall 5520 ASA 8.2.
I've got a cisco asa 5520 and setting up the NAT for multiple DMZs on it.
I want to use PAT on the outside interface.
internally ive created subinterfaces for the VLANs and connected to a trunk port on a switch.
configure NAT for this scenario. I've got only 1 external public IP address.
I will be implementing a new firewall (cisco asa 5515x) on my existing 3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the implementation successfull. I will put my 3750x as my DMZ and my 2960s as my inside. The 3750x have multiple subnet and also the 2960s.which features and technologies i need to know on those 3 products. my 3750x and 2960s don't have any ACL defined and most common features are vlan, switchport, trunking, spanning-tree, stacking, vtp.how my asa knows that my 3750x/2960s have multiple vlans. my current connection right now on 3750x and 2960s is just through 6 ports i assigned as one trunk, below is my config [code]
my 2960s vlans are almost the same with my 3750x except vlan 160, 170, 192. but of course when i put this in asa, i have to segragate vlan for 3750x (192, 100, 110,160, 170) and 2960s (130, 150). for my 2960s connection to the asa and since this will have big bandwidth, i will use 3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2 ports on my asa (and trunk it) connecting to my 3750x. the one internet ports and my one management ports on my asa will stay like that.
WE have to deploy ASA5585 in between User vlans & server vlans. we have to find all the ports that needs to be opened on firewall. any tools to do same.

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).
How many concurrent SIP channels should I expect to be able to make through a PIX firewall? We currently have a PIX 515 with the SIP fixup enabled.it worked fine for a low volume of traffic, but once we got to around 400-500 concurrent SIP calls the PIX started to struggle. Calls were dropping and other Internet traffic was intermittent. When I decreased the call volume it recovered and everything returned to normal.Bandwidth wise, we were only using about 20MB, so I think that as it needs to inspect and remember SIP packets for the purposes of opening RTP ports, we probably hit a bottleneck in terms of either the PIX's CPU or memory capacity. I've not seen any specs detailing how many SIP fixups a PIX (of any capacity) is able to handle.I'm thinking of upgrading to a PIX 525 or PIX 535, but I'd like to know how many SIP calls they will be able to handle before committing.

How to provide communication between two different interfaces which had configured as same security level?
How many trunks will support ASA 5510 with base-license?
How to configure trunk to an interface with different VLNs( Router on a stick).
I have a working environment but wondering if there is just a better way to accomplish what I am trying to do (without a layer 3 or 4 switch). Basically I have a few sub interfaces on my Cisco ASA5510.
Now what I do need is some of the VLANs to communicate with specific devices on the different VLANs. So for example I need computer 1 from VLAN 5 to communicate with 192.168.10.5 from VLAN 10 on ports 80 and 443.
What I am currently doing is settings the security level to 100 on each interface (including the DMZ).
Here is what I have:
interface Ethernet0/1.5
vlan 5
nameif Sub5
[Code].....
configure ASA 5510 as below
inside users should communicate with Hosts on the DMZ Zone and at the same time they should go for internet towards outside interface
ASA with 8.3(1)
default security levels
attached is the digram for your reference need communicate form inside to DMZ
I've been following most of the comments in regarding how to allow communication between two internal networks on a ASA5510 8.2.5 But I am still a little confused about to how to set my firewall. I made chages to it and still do not have the desired results.
I need to allow comunication between Interface 0/1 and Interface 0/2. See configuration file with fake or dummy ip address below.

Is it possible to provide communication between two different interfaces which had configured as different security level in ASA 5510?
View 3 Replies View RelatedI have a Cisco ASA 5510 configured to access the internet, with an:
inside interface (ethernet 0/1) 130.130.0.254 and outside interface (ethernet 0/0) x.x.x.x
I have now configured another inside interface (ethernet0/2) on ASA with the IP 172.16.0.254 and I have connected it directly to another switch with a management IP 172.16.0.5.
The problem is that the two inside interfaces (130.130.0.254 &172.16.0.254) cannot communicate with each other thus the e0/2 172.16.0.254 interface cannot access the internet.
I'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
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.
I have an asa 5520. How would I configure my dedicated management interface to be able to route off subnet while the firewall is in transparent mode?
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.
Recently, I deployed ASA 5520 as our company firewall, everything was working fine except two main problem I still can not resolve them after I did a lot of research.
1. DNS rewriting - The internal user can not access the DMZ or internal server by put in the domain or external ip address. such as [URL] will resolve our wan ip address 210.0.0.83 ( internal ip address is 192.168.1.21 ).I used static (inside,Outside) tcp 210.0.0.83 https 192.168.1.21 https netmask 255.255.255.255 dns, but it will not work. We have our internal DNS server, but don't want to just add the domain as a record. Is there anyway to get the internal user to access Internal server and DMZ server through the public domain?
2. We also have an internal multiple subnet, another router was conneting to ASA firewall inside interface and using ip address 192.168.1.223, another subnet 10.1.15.16/28 is behind the this router, for the users in subnet 192.168.1.0/24, they connect firewall inside interface directly.I added an static route and intra-interface permit route inside 10.1.15.16 255.255.255.240 192.168.1.223 1same-security-traffic permit intra-interface I also added access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 10.1.15.16 255.255.255.240access-list inside_nat0_outbound extended permit ip 10.1.15.16 255.255.255.240 192.168.1.0 255.255.255.0nat (inside) 0 access-list inside_nat0_outbound The internal users on 192.168.1.0/24 can ping 10.1.15.18 but can not telnet to 10.1.15.18 22. If I set 192.168.1.223 as one of the workstation on 192.168.1.0/24 default gateway, it can telnet to 10.1.15.18 22 without any problem.
As this is an ASA 5505, unlimited users, I must use arp alias to allow a secondary network.
Inside network: 10.200.31.0/24.Additional inside network: 10.200.12.0/24
Clients in both networks can reach internet, but they can't communicate with eachother. Hosts on the additional network can ping the ASA inside network IP, but nothing else. I get incomming hitcount for inside interface when 10.200.12.x tries to ping 10.200.31.x. In the error log, I see: [code]
ASA 5505 and DMZ, I have a Base License.
What do I need to do for access inside network to DMZ?
I successfully configure, internet Access for DZM and inside network, web server can be accessed from internet, but I have problem to configure communication from inside network to DMZ.
I try to launch a LAND Attack against my firewall ASA 5520. Everything will work fine. But why, I think it should not work. I use a little tool where I can user a spoofed address, with a cluster shell and attack the firewall interface with the source of 127.0.0.1 ore the ip address of the interface as the source and destination. Then I get a cpu load of 89% with only two host. With IP tables I can use kernel processes to prevent this. But I don´t find anything for ASA.

I wanted to know about EHWIC 8-Port configuration? We create Data and Voice VLANs and assign 8 ports to the VLANs. So how do VLANS communicate with each other? We cannot make Gi0/1 as sub interfaces and assign the same subnet IP’s as of VLAN IP’s , it wont accept. On 1921 router Assume Gi0/0 we connect to MPLS WAN. What happens to Gi0/1 where do we connect this?

View 2 Replies View RelatedI have an ASA 5520 in my company which does all our NAT and Firewall access control. Currently there is a rule in place to allow an incoming connection on port 2222 from a specific ip address to allow access to a web app our developers created. This is a test before the web app is released live. Now the web app can communicate with the specific address and port but the incoming connection on port 2222 isn't getting through. Everything looks great in the firewall but how can I log any hits this ACL takes to identify any potential problems?

I am setting up a network that will use the 1941 router with a cellular card (HWIC) to connect to the Internet for communication with remote stations in the field. The 1941 has a static IP address (166.142.xxx.yyy) on the Internet provided by the ISP (Verizon). The 1941 is connected via ethernet to the ASA5510. The end goal is to have the field cell routers (Digi Transport WR-44-R, also static IP) connect to the ASA5510 via VPN tunnels for communication back to the servers behind the firewall. I'm not sure exactly how to configure the 1941 so that the remote router can connect to the ASA using the public IP of the 1941 router. I have the 1941 working stand alone and can connect to the Internet and pass traffic, but I tried a static NAT to translate the public IP to the private IP of the ASA and cannot pass traffic. below is part of the 1941 configuration: [code]
Do I need to use VLAN bridging to accomplish the task or am I missing something with the NAT?
Need to know if ASA 5520 does Layer 7 firewall or not?
View 2 Replies View RelatedTwo days ago, we changed our old 525 with asa 5520 ( ver 8.2 ). Configuration is the same, except the version. It even retains the same global interface and static public ip address as the old device.All worked well during that period.
Yesterday, one of the http applications , not tested other day, was found not to be working. To test, we switched back to the old 525 , however nothing was working when we did that.
