Since the power failure two days ago, my -ASA stops forwarding traffic to internal servers, for no apparent reason. Packet trace shows all OK, packet capture buffer stays empty when I try to http into the mail server. The only way to get it working is to change the Outside Ip to the one used for mail, then to change it back. It will work OK for a few hours, then stop, with nothing obvious in the logs.
Cisco ASA 5510. Between 5 to 10 minutes of reseting the asa traffic stop accessing outside ip addresses. Ping from console fails to ISP router IP. Ping to google name server failes. I have reset to factory default only setting up nic and natting and it still happens.
I'm new to ASA's and PIX units. I've setup a few VPN's now but know next to nothing about logging on these units. I read the config guide for the PIX, but cannot figure out how to get a log of incoming SMTP traffic going on the console.Do I need to use a SYSLOG server? I can probably set one up on my laptop.
I am trying to switch out a cisco pix 501 firewall with a cisco ASA 5505 firewall. I am not very familiar with all of the commands for the firewalls and have always relied on a standard command line script that I use when building a new one. Unfortunately, my script is not working with the 5505. What I am doing wrong with the following script? I've masked public IP info with xxx.xxx.xxx and I run it right after restoring the firewall to the factory defaults. I am able to get out to the internet if I browse directly from one of the servers, but cannot access a web page when trying to browse to it from an outside network. [code]
I was configure 3 interface on ASA1st - managemetn (only for management)2nd - gig0/0 is connected to internet with real IP3rd - gig0/1 is connected to local networkI was configure routed NAT to internet.But I have problem with restriction incomming traffic to inside interface (ifname is inside)but I can connect to ip address of inside interface from other ip. It is wrong and i can't understand where is my mistake.
We have a Cisco ASA 5520 and im looking for a way to monitor largest outgoing and incoming traffic per ip in real time so to know which of my internal computers are using the most of our Internet Line. Is there a way to this through ADSM ? We use version 6.3.
We have a distributed ACS 5.3 set up - a PR and DR replicating successfully.I've set up 4 remote syslog targets. 2 of them are at the same site as the PR ACS and 2 are at the same site as the DR ACS.The logging collector is set on the PR ACS.
The problem is that it "appears" that PR ACS is only sending PR ACS syslog info to one of the remote syslog targets out of the four.
The syslog target which does receive from the PR ACS is at the same site as the PR ACS.
"appears" means that some one has looked on the syslog targets to see what's been received / or not received.
I've been told that the syslog traffic for syslog targets is being received from the DR ACS. Which is strange as the PR ACS is the actual log collector (and is not at the same site as the DR ACS).
I've also got Alarm Syslog targets set up on the PR ACS , (2 are the same ip addresses used in the 4 remote syslog targets). IP addresses of the remote syslog targets have been double checked and can be pinged from each ACS (PR and DR).
I have a classical "inside + DMZ + outside" configuration.I also have a mail server in DMZ which have to be allowed to reach any destination on the outside (internet) at least on the SMTP port, of course.If I make an access rule that allows traffic from that server to "any", everything works fine, but doing so the server is allowed to reach any destination, including what is behind the inside interface (internal network).I didn't find any other option to tell the ASA machine to allow any destination, but on the outside interface only.I do believe is possibile to have the ASA to allow any kind of traffic from a host on the DMZ to the outside interface only, but I didn't figure out how.
P.S.: I'm using a 5510 machine running version 8.2
Im using a Linksys E4500 wireless router behind a Motorola SB6121 modem. My OS is Windows 7 and it is fully up to date. In general my entire network is working well. Now I have purchased a new IP surveillance camera and need to forward a port to be able to have remote viewing of the camera. Mi ISP blocks quite a few inbound ports including 80 so I have been trying a lot of ports all over the map to find something that will allow inbound access.
After several hours, nothing I have tried works, using a couple of different port probes including one called CanYouSeeMe I always get a "timed out" message. I have disabled the firewall in the router and on the local computer and still no luck. This says to me that either Cox is blocking nearly all ports (doubtful) or the modem is blocking access to the router somehow.
The Surfboard modem doesn't have a built in router. Unfortunately I don't have an old working modem to put in the circuit.
I don't guess it matters but the camera is accessible from all other local computers on the LAN using its IP address with a port number appended (right now it's using 8000).
We have the next Settings in our SW. We crate an ACL and aplied to a SVI for Incomming Traffic, I understand that is not necesasry to allow the returning traffic in ACL, but we can't access to rdp for example when we add the ACL, if we remove it, the acces is ok, buet when we add again the access is deny, even we have a log entry, and the ACL i just for Incomming traffic. There is no another ACL.
I have a licensing server. Other computers need to turn on a program, they send a message to the licensing server, and it responds that they have permission to run.Until today the licensing server was plugged into its own ethernet wall socket and configured with a static IP address. Today I put a router into that wall socket and now the server's plugged into the router.The router (WRT-54G) was set to the static IP - and now the internet on its network works. I set all ports to be forwarded to the server's internal IP address - and now my programs can detect and ping it. But now the server won't send back permissions to use licensed software, or even reply with a list of the software which it can license.
Just wondering if there are any methods or commands, natively, in the asa5510 for determining all traffic in to and from a certain server passing through the asa. This would be without a syslog server or something similar.
Core Internal Network -> Cisco ASA 5510 -> DMZ Switch.If i send a ping reguest from internal network to servers in DMZ Switch over the ASA 5510, i can see a delay in response, some times this delay can be more than 80ms, this is a problem for the web applications in http traffic.How i can find what's happening on my ASA? I disable the inspect traffic over the IPS, disable the policy maps below, reload the two boxes, but doesn't works, the problem still persists. [code]
I'm currently using ASA 5510 with software 8.4.1 and I have an issue with nat configuration. I used the following config line:nat (inside, dmz) source dynamic LAN Pat1 destination Server1 Server1
The traffic is not flowing and when I use Packet Tracer, packets are dropped at the NAT rule with the following error: Drop-reason: (acl-drop) Flow is denied by configured rule.The only ACE I have is permit ip any any.
I have an ASA with an outside ACL that is configured to allow 220.127.116.11 SIP/5060 to 1x.x.x.46. I show no hits. I added an ACL to do a packet capture, it sees the packet coming into the ASA but not going to the Serv Prov interface. I see hits on the vuong ACL but not the production acl_out ACL.. What is up?
NOTE:ACL_out is the ACL we use to allow outside traffic to enter our network. FW1(config)# sh access-list | i 1.x.x.46 access-list acl_out line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0xc09a9387 (*NO HITS) access-list acl_out line 658 extended permit udp host 18.104.22.168 host 1x.x.x.46 eq sip (hitcnt=0) 0x0f327179 (NO HITS) [code]...
It was tested and verified from the inside network to make sure the server is listening on that port. Below we created an ACL to allow all IP from another test PC to the Server IP 1x.x.x.46. We did a telnet to port 5060 and it showed hits but not on the acl_out ACL.
Below we applied the same ACL to the ServProv interface to see if traffic was going where it was supposed to . By trying to telnet to the 1x.x.x46 IP from 63.x.x.140 IP. Looking below, no traffic appeared on the capture2.
I have manually configured the Firewall ASA 5510 from existing PIX to match the configuration, however when I connect the firewall to the Network, no traffic is flowing in either direction. I have the Inside network on the 172.29.0.0 subnet and the outside network on 22.214.171.124 subnet. I am attaching the cofiguration file.
I have been struggling to come up with the proper config to do a NAT of an incoming VPN tunnel to a VLAN on my network. I have an ASA 5510 with an IPSEC site-to-site tunnel to a partner network of 126.96.36.199/17.I have several VLANs on the ASA interface behind a cat4500 router (192.168.100.024, 172.16.4.0/24, 188.8.131.52/22 etc). The only network that the partner network sees is the 184.108.40.206/22.My problem is that I need to give them access to a node on my 192.168.100.0/24 net, but can't get the admin on the other side to add a route and adjust his tunnel.
We have a switch gc2960. It has ports configured on vlan 27 and vlan 29.It is connected to switch ch3550. It has presence of vlan 27 vlan 29 and also vlan 18 and several other vlans.Our internet firewall is connected to ch3550. It is a fortinet product, so this is not indicated on the diagram.
When the two switches were connected on vlan 29 access ports, pc's on vlan 29 on gc2960 worked as expected. vlan 27 clients of course did not work.When we switched the connecting ports to trunk ports, some weird stuff happened. Clients on gc2960 on vlan 29 could ping and resolve dns, but not browse the intenet. The same was true for clients on gc2960 vlan 27. We verified that packets from the web were coming in through the firewall. What we were thinking, is that they somehow were not being tagged to vlan 29 even though we were trunking.
When we set native vlan 29 on the trunk, then clients on gc2960 vlan 29 operated as expected. However, clients on gc2960 vlan 27 are still having this problem, we can ping and resolve dns but not browse.Consider the other switch ch2960-jstreet which has presence of vlan 18 and vlan 27. It is also connected on trunk to ch3550. We are not using native vlan on this trunk, and traffic works as expected.Is the lack of presence of vlan 18 a factor as to why gc2960 is not receiving the tagged packets correctly? Should the interface vlan18 on gc2960 have an ip address on the vlan 18 network?
We have Cisco ASA 5505, 90.x.y.2/29 IP is assigned to outside interface. We have one internal HTTP server so that I use static (inside,outside) tcp interface [URL] to forward all incoming HTTP traffic to internal HTTP server 1. Now we need to add new physical HTTP server 2 so that I would like to forward
HTTP traffic to e.g. 90.x.y.3/29 to 172.16.0.11.
How can I do that? See scenario image (scenario.png) if needed.
I need to block incoming traffic with Dlink DIR 600. I know how to create the rule source (WAN) to destination (LAN) to deny all protocols. But what IP will I put in WAN? IP address of my Internet? Or how can I enter the ALL IP range in source...format for the IP (it's not 0.0.0.0).
I want to do this because in the DIR log section I'm being PING Flooded. I already un-check "Enable WAN Ping Response" but still receiving the message.
I use ASA 5510 and I would like to log VPN traffic ( for example, as soon as a remote user try to connect to the asa). I would like this log be send to a specific mail address. I already configure Email Logging for severity ( level 3) and it works well.
i would like to use ISP2 for all http/https/ftp traffic.how could I force my ASA to set a different gateway for http/https/ftp traffic ?i have tried several solutions such as nat/pat rules, nothing seems to work.
FTP traffic routed from outside to the inside interface works fine. I have another interface with multiple sub-interfaces and vlans configured. FTP traffic routed from the outside to vlan2_servers is not making it through the firewall. I must be missing something. I have attached my config.
I have ASA 5510 8.4 Firewall where more than 20 Site to Site VPN Clients are configured on it. how to see the traffic for one Specific Site to Site VPN.Actually this site to site vpn is always keep dropping for every minute. I'm sure its a problem at the other end.The remaining 19 VPNS are UP and working without any problem. How to see the traffic for specific vlan.More over we dont have any syslog server in our network. Is their any chance we can check the traffic on the firewall?
I have a private network behind a configured Cisco ASA 5510. I need to send data back and forth between a server on the inside network and a device on the outside network on port 44818. No amount of configuration is allowing this to happen. The packet tracer always fails on of the implicity "deny" rules, even though my other rule should explicitly permit it. I also realize I need to set up routing from my outside network to the inside network, but I cannot see from the documentation how to do that on this particular port without simultaneously breaking my outside connection.
The inside IP for the ASA is 192.168.25.1 The outside IP for the ASA 192.168.11.54
Here is my current configuration:

I have little experience with firewalls, what I've learned has been by dealing with issues like this that arise from time to time.I know, I need to upgrade the version. It's in the works now. Anyways, my question/problem is: Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running contstantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.
We are using an ASA 5510 as our gateway to our ISP. All of our VOIP traffic is sent to an Internet SIP provider for our outbound calls. Our pipe to the Internet is 100Mbps metro ethernet. I am trying to find a way to provide QoS for this traffic so that I can reserve 20Mbps of the available 100Mbps pipe for VOIP traffic.From what I've been able to figure out so far I would use a combination of priority queues and traffic policing. However, it seems that this is nearly impossible to accomplish because I cannot control the remote device that my ASA connects to because it is the ISP device. I could police traffic on the inside interface of the ASA. However, lets say that a client on our network starts downloading from an Internet host and the downloaded traffic saturates my Internet connection. I could police this incoming (from the Internet) traffic on my outside interface of the firewall. This would drop the packets but the bandwidth would have already been used by the time it reaches my firewall.Would the fact that I'm policing incoming traffic on my outside interface cause the sender to throttle down their transmit rate because packets are being dropped? Would this achieve my goal of guaranteeing available bandwidth for my VOIP traffic by not allowing other traffic to saturate the link?Most documents I find regarding this topic describe providing QoS for VOIP traffic traversing a VPN connection in which case you could configure both end devices.
