Cisco Firewall :: ASA5510 Allow Traffic From DMZ To LAN
Sep 18, 2011
My device has 3 interfaces configured: inside, outside, DMZ. Right now I can access the DMZ from the Internet and I can access the DMZ from the LAN using an exempt nat statement. I am having a few issues setting up DMZ > LAN access however. The servers running on the DMZ need to send information to my LAN such as syslog traffic for example. Will DMZ traffic be NATed or should this somehow be excluded? Bascially all LAN devices should get to the DMZ devices by their actual IP and vice versa. Are there any special statements I need to add to the ASA such as nat or ACLs to make this work? My LAN is 10.10.6.0/24 and DMZ is 192.168.254.0/24.
I have ASA5510. It's include security plus license.I want to traffic shape to 200Mbps. But , I checked a CCO.CCO said that a shaping limit is 154400000. "Enables traffic shaping, where the average rate argument sets the average rate of traffic in bits per second over a given fixed time period, between 64000 and 154400000. "It's mean shaping limit 154400000 ?Can I shape to 200Mbps ?
I have just set up a Cisco ASA 5510. It basically only contains the settings provided in the startup wizard. It however does not let through traffic from the internal interface to wan 2 (wan 1 is not connected yet but traffic should also be able to go there).
I would like to connect a second ISP link to our ASA 5510 to solely serve http traffic from our organization's employees (ie. web surfing). We currently have all employee traffic and two site-to-site VPN tunnels connecting to the internet from this firewall. I want to keep the tunnels as currently configured on the existing connection and split out http/https traffic from our staff onto a less costly link.
I have an ASA5510 with 8.3 and a Cisco PIX525 (retiring). The ASA was for VPN traffic only while the PIX was for all other Internet traffic. I'm trying to move all the traffic to the ASA5510 so I used the PIX to ASA migration tool. I migrated the PIX rules over to the ASA5510, however we can't receive email and there is no external access to our internal websites. But the VPN connections remain intact and internal users can get out to the internet.
When I run Packet Tracer on my outside (incoming rules) the packets are dropped at the inside interface. What am I missing?
I ' m not able to configure the asa 5510 to allow the multicast traffic to pass through ASA.The multicast traffic have to pass from inside interface to outside interface.Can I configure the multicast traffic to pass through asa with a static nat ?
I am having an ASA5510 with a CSC-SSM-10 module. I am able to block http traffic through the ASA but cannot block https traffic through it. Need to block https traffic using the CSC module.
I've been trying to figure this one out for quite a while. I currently have 2 inside interfaces (data, phone) and I am moving to 3 inside interfaces (servers, workstations, phones). I have not been able to get any traffic between the interfaces. With the current setup it was not a major problem. With the new setup it will be a major problem.
Up until recently one of my sites was able to get to a postilion subnet. Then we started receiving "host unreachable" e-mails. Posting told us SMTP traffic was not getting let in. I've compared the current config to a config that was saved before the issue popped up and found really no noticeable difference.
I tried a packet tracer trace with no luck: SiteB- Firewall# packet-tracer input outside tcp 11.2.2.36 12345 65.19.0.0 25.
Phase: 1 Type: FLOW-LOOKUP Subtype: Result: ALLOW Config: Additional Information: Found no matching flow, creating a new flow [code]...
Result: input-interface: outside input-status: up input-line-status: up output-interface: outside output-status: up output-line-status: up Action: drop Drop-reason: (acl-drop) Flow is denied by configured rule
Attached is a sanitized config. I'm not entirely convinced it's a firewall issue, but I need to some successful testing to prove otherwise.
I am using ASA5510 and i want to know if it is possible to redirect http traffic to an internal proxy software. I explain : PC from the LAN use a internal proxy in their IE browser but some other PC doesn't use it.They are directy connected to the Internet using the Public IP from the WAN interface ( via NAT). Can we redirected this HTTP Traffic from the WAN interface to the Proxy in the LAN ?
Http Traffic will be routed like that : PC -> WAN interface -> Proxy -> WAN interface -> Internet In fact,can we create a rule saying : All http traffic which doesn"t come from the IP Proxy must be redirected toward proxy.
ASA 5510 have two model Bun-K9 and Sec-Bun-K9 from the datasheet find out difference Port related and Redundancy. My questions is : Have any major difference for Security service between two model ?
Although this is not a common issue, we have experienced occasions where our internet utilization has been maxed out (slowing everyone else down). Utilizing some features in the ASA, such as Top Usage Stats, along with PRTG monitoring, have always tracked the culprit down to being a single user -- be it someone downloading movies to a portable device, or downloading ISO's. (And for some strange reason it seems to always be a wireless user.) We are using an ASA 5510 for our firewall, and I was wondering if its possible to prevent a single client from consuming a disproportionally large percentage of our internet bandwidth? If the ASA 5510 doesn't have the ability to do this on it's own, are there any recommendations for add-on solutions?
ASA5510 configuration, I would like to know if it is possible (and how) to forward traffic received on WAN port of the first ASA to the server in LAN on the other side of VPN tunnel:
Internet (IP 85.128.50.x) – ASA5510 (192.168.1.x) – VPN tunnel – ASA5510 – LAN (172.16.71.x)
I need to have IP 85.128.50.50 redirected to 172.16.71.15 through VPN?
I currently have a site to site VPN running connecting a branch office and the Main office using a ASA5510 and ASA 5505. currently PC's at the branch can access the network in the main office using interface 0/1, but we have added another ip range using interface 0/2 and I can't seem to route the traffic to both interfaces. I currently have 0/1 as inside 192.168.10.1 which works, and have added 0/2 as Inside2 192.168.20.1. I know I am forgetting something, any commands to route incoming VPN traffic so PC's at the branch office can connect to both IP ranges?
We've created an ipsec VPN tunnel between our ASA5510 (8.3) and a Pix firewall (not sure of the specific version, etc).
The tunnel works fine, except for timing at times (traffic only goes through a few times a day), and a wierd problem with all traffic being allowed even though I'm only allowing specific ports (SFTP, SQL Server 1433) from a network at the client site to a specific server in our Data center.
I was surprised that I could RDP into the server, as well as telnet any other port exposed on this server from the client site. Now as I write this i realize that I did not check whether any of our other data center servers can be reached via the tunnel.....
Not having set up many VPN tunnels before using ASA (only Checkpoint - Checkpoint before this), I'm wondering whether i need to include another rule in the VPN tunnel cryptomap to deny all other traffic from their network to our network, or whether there's a global config I need to add a rule to.
I am moderately conversant in the command line, but because of my lack of Cisco VPN tunnel experience I did use the ASDM site-to-site VPN tunnel wizard to set the tunnel up. Not sure if there were any defaults i would have to override using that method.
We have many VPN tunnels back to our corporate office. All of these tunnels are very slow (same with our client VPN's). Our main firewall device at the corporate office is an ASA5510. We have a 100 Mb/sec Metro Ethernet internet connection here. We do not allow split-tunneling.
Our remote sites vary. We have DSL connections, cable internet connections, and other types of broadband that vary in speeds from 5 to 100 Mb/sec (up and down). The remote sites mostly have PIX 501's, but we have an ASA 5505 in one of the locations.
To take an example. On one of our remote sites that has a 100 Mb/sec connection, if I ping device to device, I'm getting ping times of about 50ms. And I'm pinging back through another 100 Mb/sec connection. If I get on a computer down there and run a speed test, I'm showing down speeds of about 1.5 Mb/sec... nowhere near 100. Some of that could be due to the lack of split tunneling, but I also suspect this could be an MTU issue.
Right now, all my MTU's are just set to the default 1500. Perhaps this is too high. I used this site to check my max: [URL]
I did a few tests from behind several of my firewalls. I pinged from a machine on one side of the tunnel to the firewall on the other end. I'm assuming the max MTU I come up with is the max MTU for the firewall I'm behind while pinging, right? The max amounts I came up with for some of my devices were as follows: Corporate ASA 5510 > 1272 (if you add the 28 byte packet header that would make it 1300) Remote PIX 501 > 1416 (if you add the 28 byte packet header that would make it 1444) Remote ASA 5505 > 1418 (if you add the 28 byte packet header that would make it 1446)
So, do I just need to set my MTU values to the appropriate amounts? I have tried changing the value, but I don't see any change in speed/performance. But I also don't know if I need to reboot the firewalls after changing the MTU. I know with Catalyst switches, you have to reload. But I didn't see any messages about needing to reboot on the ASA's/PIX's.
I have a asa 5510 with 8.x software and I want to reserve (i mean RESERVE not PRIORITIZE) traffic based on protocol, like if I have a 10Mbit I want to :
- give 3 Mb for smtp
- give 5 Mb to http/s whatever
- 2 Mb for other stuff.
Of course QOS won't do that, can you do that with ASA?
We are looking to implement traffic shaping/policing primarily for P2P traffic. As natively the ASA5550 is only capable of p2p inspection if the traffic is tunneled via port 80 is the AIP-SSM the way forward? We have 2 5550s in active/active failover config. As a side note we are also looking to implement an IDS/IPS system so could this module cover all?Is this module going to provide the desired outcome or is there another module/device out there better suited for this? I would prefer to use the ASA5550s as opposed to implementing another product if only that we can make use of the investment we already made on these devices.
I am testing limit bandwith using my ASA 8.2, i am trying to limit internet access for certains users , i order to save Bandwith for the important things but i can´t get any limitation
My configuration is the following, the acces list is just for my pc in order to test, and the service policy is applied to outside interface (called internet in my case) for incoming traffic
access-list Internet_mpc_1 extended permit ip host 172.16.127.70 any class-map Internet-class-TEST match access-list Internet_mpc_1 policy-map Internet-policy-web class Internet-class-TEST police output 1024000 1500
service-policy Internet-policy-web interface Internet
With show service policy i can´t see any activity on the policy , but if i do a similar configuration for inside interface outgoing traffic i can see packets allowed and dropped
I have a SMTP relay deployed on the DMZ for mailing. I have also a mail servers installed in the internal lan,
I want to allow trafic from dmz to reach internal lan, and i want normally also allow stmp relay from dmz to reach Internet.
How can i block trafic from DMZ to reach Internal Lan (instead of smtp) if the to allow trafic from dmz to internet i must put ANY in the policy?
For allowing trafic from DMZ to reach Internet, the policy must be DMZ -----> ANY ----->Services., this policy means DMZ can implicity reach Internal Lan?
I am able to ping from Switch to firewall inside ip and user desktop ip but unable to ping from user desktop to FW Inside ip.. config is below for both switch and FW Cisco ASA5510....
TechCore-SW#ping 172.22.15.10 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.22.15.10, timeout is 2 seconds:
I have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?
i have a ASA5510 in the office, that already configured 3 context, namely, admin, user, server.in the server context, the last running config was not saved, and there was a power trip last friday night. 1 of the sub interface was affected, and i need to recreate that interface.I am getting the below error, it only allow me to do changes those pre-defined interface.how to I create extra sub interface?
I have a cisco asa 5510 with security plus license in Live enviroment . I need to add a secondary firewall . I was planning to do in active /standby mode for failover .But i have a doubt , when i do "show version " on live asa output says Active /active failover , does this means that i can only configure failover in active/active mode not in active/standby (which i want to do )?
i am using Cisco ASA5510 Firewall in my Network in the distrubition Layer .Private Range of Network Address use in the Network and PAT at the FW for address translation.presently encountering an issue the users behind the FW in my network unable to RDP at port 2000 presented at the Client Network.Able to Telnet on port2000 but not RDP . any changes needed at the FW end to get the RDP Access.
We have to use scp on all of our network devices. It worked quite well on our routers and switches but I can't seem to get it to work for the firewalls and IPS. I enabled scp on my ASA5510 using the command "ssh scopy enable". I also ensured that a rsa key was generated and that ssh ver 2 was enabled. But I can't seem to locate the commands to actually have my firewall either copy it's configuration to a server or reach out to a server to pull down a file. We are using IOS 8.2(1).
I have a customer who wants to prioritze rdp traffic throgh the firewall.I know that its port 3389, but outgoing traffic is a random port number.Any smart way to catch this traffic and get it in the LLQ ?
we have ASA 5510 which we need to upgrade from 8.0(3) to 8.2.5. can we directly switch to 8.2.5 from 8.0(3) , if not what all versions we need to go from.
What all point needs to check before that following is show flash output.
I have a ASA 5510 with asa8.4(2) and asdm6.4(5)205. Have a new basic config, nothing special at this time. I just cannot seem to get from the inside to the outside. From the outside interface I can ping, so I have a good Internet connection. [code]
WE have a DMZ on ASA5510 8.4, it can access anything internal interface but cannot get out to internet or outside interface. I try to ping from a host in the DMZ to 8.8.8.8 and get this in the log 6Apr 25 201208:24:431100038.8.8.80172.10.1.1501Routing failed to locate next hop for ICMP from outside:8.8.8.8/0 to inside:172.10.1.150/1. [code]
I am having ASA5510 firewall which has 1GB RAM currently. I want to upgrade to 2GB. When I opened the box, I can see only 1 slot to insert the RAM. I searched in Cisco website and I got to know that I need to use 2 x 1 GB RAM. So, I need to have 2 slots to do that. But, I am having only 1 slot in the box.
