Cisco Firewall :: Configure ASA 5510 For Individual Server Traffic Routing
Jan 27, 2013
I am wondering if this is possible. We have multiple internet connections with fixed IP's coming into the office. We'd like to use one for FTP backup and another to service our websites. From what i have read a 5510 doesn't do policy based routing, but we'd like to configure our ftp server to use one of the internet pipes and our webserver to use another internet pipe. Is that possible?
We'd have two outside fixed IP interfaces and two internal interfaces. I could then use one of the internal interfaces for the web server and the other for the FTP server. consequently if the internal web server and FTP server use the fixed IP"s corresponding DNS server wouldn't that effectively route all FTP traffic out one interface and all web traffic out the other?
Then the FTP traffic would be NAT'ed to an internal interface and the HTTP & HTTPS traffic would be NAT'ed to a separate internal interface.
Then if each of the internal servers used the corresponding internal NIC on the ASA as it's gateway and the fixed IP's that correspond to the external DNS server, then it would affectively only use that gatway out for traffic? Would that work? Does it should route traffic out those pipes correct? Will the asa support two different next hop routers for the two different interfaces?

We have configured ASA 5510. We have configure Ethernet 0/0 ( Outside ) connected with ADSL line and Ethernet 0/1 ( Inside ) Local LAN. we have configured NAT and all the traffic is passing through outside interface. Now we have connected ethernet 0/3 ( leasedline ) interface with static public IP. Now we want to allow SMTP traffic to pass through from this interface.
How to configure it if we want our local lan SMTP traffic sending through new leased line ( Static Public IP ).

I am having an issue when implementing an additional internet connection on our ASA 5510. The new connection is "TWCOutside". I was my understanding that static NAT would force our externally hosted servers (Email, PPTP VPN, and FTP) to continue to utilize the "ATTOutside" connection. Our remote site-to-site VPN traffic has two static routes configured to force it to continue to use the ATTOutside connection.When I switch the metric on the 0.0.0.0 0.0.0.0 98.103.148.145 route to 1, and change out default dynamic xlate to use "TWCOutside", it "mostly" works as expected. Email, the PPTP VPN server, and our remote site-to-site VPN server continue to use the ATTOutside connection as designed. Our end users begin using the new connection for thier internet browsing.
However, our FTP server, in the DMZ, completley loses outside access. It cannot ping to 8.8.8.8, or resolve DNS queries. The is a static NAT statement for this server, as it is using one of our dedicated public IP addresses. I need it to continue to do so for the next few weeks.Effectivley, we just want to give our end users internet browsing on the new TWC link, but leave everything else on the old ATT link for the time being. The only problem I am having is the DMZ connection. I am currently "rolled back", so no one is using the new connection until I figure this out. I can easily switch the metric and dynamic PAT back to using the TWC connection, but I need to have some things to try with the DMZ before doing so. [code]

Is there a way to configure a DHCP server for my internal subnet of 192.168.20.1 which is on a 3550 layer 3 switch from my 5505 ASA Firewall.My subnet of 10.1.1.0/30 is connecting my 5505 to 3550. All I'm trying to do is run a DHCP server down to my hosts. The only options on ASA 5505 is
dhcpd address 192.168.20.1 - 192.168.20.254 outside or inside, which conflicts with my subnet of 10.1.1.0 used to connect my internal subnet of 192.168.20.1 for the whole network.
When I used my router it did not need the (inside, outside) keywords and just an ip helper-address command. How do I configure my my firewall DHCP server to propagate the 192.168.20.0 network through my 10.1.1.0 connection.

I have several VPN sites terminating on a 5510 firewall. all work fine but i cant get the traffic from the VPN sites to communicate with a server on a dmz on the same firewall.
a packet trace from the outside to the dmz shows this:Type: VPNSubtype: encryptResult: DROP
ive configured access to the dmz the same as to the servers on the inside. I can get to the inside servers ok.

I'am using ASA 5510 and I try to understand how PAT is working.I want to add a Mail Server in the LAN and a webmail using port 3000 on the server. ( webmail must be reachable from the WAN)This is my Configuration :actually LAN users access internet using NAT with one global IP ( 194.x.x.69) which is the ASA WAN interface.
WAN ----- ISP Router ---------- FW ---------- LAN -------- Mail Server + Webmail
| (25) | (3000)
194.x.x.69 192.168.1.254 192.168.1.6
I need to forward port 3000 and port 25 from outside to inside.For example, from the WAN : [URL] must be redirect toward 192.168.1.6:3000 . What is the Correct Configuration ? And what about the Inside/Outside Traffic,Is there any configuration to add ?

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

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.

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 208.84.248.95 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 208.84.248.95 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.
ccess-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0x2759fa92
FW1(config)# q
FW1# capture capture1 access-list vuong interface outside
[code]...
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.
FW1# capture capture2 access-list vuong interface ServProv
FW1# sh capture capture2
0 packet captured
0 packet shown
[code]...
Capture 1 above shows the last 3 incoming messages initiated from 63.x.x.140 to the 1x.x.x.46! Vuong ACL belows shows 3 more hits.....nothing on the acl_out ACL???
FW1# sh access-list vuong
access-list vuong; 1 elements; name hash: 0x29df3e90
access-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=6) 0x2759fa92

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 20.2.0.0 subnet. I am attaching the cofiguration file.

One Host on inside network needs to access customized application hosted on Internet. Its a customized application run on port 80, 443, 5000-to-50020
How do I allow this host access for this specific application. I got ASA 5510 and host is in the inside network, we also got an ACL on inside interface to have control.
-Host IP on inside network - 172.16.30.15
-Application to access - 74.219.x.x

My setup is as below
inside host--> ASA1--Outside interface- layer_ 2_Switch1--outside interface--> ASA2--inside interface-DHCP SERVER.
We want that inside host should get ip from subnet 192.168.10.0 /24. This ip pool is configured in DHCP server (ip 172.16.10.1) which is connected to ASA2. There is no routing issue as we are able to ping DHCP srever 172.16.10.1 from ASA1. to do config needed on ASA1 and ASA2 , so that host connected to ASA1 inside interface can get ip from DHCP srever. We have configured 192.168.10.1 /24 to ASA1 inside interface which will be gateway to inside host of ASA1.

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.
How I can add the VPN traffic Log ?

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.

Recently moved into the hardware firewall space and have a ASA 5510. Having some issues trying to get traffic through the box to my 4 dedicated servers. all the servers have static IP's and are connected to a private switch into one of the ethernet ports on the firewall(0/2). Public internet connection into another(0/0). 1 of my servers has a connection to the management port, and the public switch, and this is the one im trying to do the configuration on.
Im unsure what to set the IP address of my "outside" interface as. need to have RDP,FTP, HTTP traffic going to each of the 4 servers independently, pretty sure i can get the rules in place to allow this, but cant seem to get any traffic to go through the firewall to any of the other 3 servers.

I am confiuging a DMZ on my ASA 5510 but I have run out of physical ports, since I have dual Wan ports configured. I plan to implement a DMZ using subinterfaces. I have 2 questions:
1) Do I need to configure a Vlan to complete this task?
2) Do I need to re-configure the other interfaces for subinterfaces and/or vlans as well?
