I am using an ASA5510 for internal firewalling in my QA environment. How do I allow RDP from one subnet to those protected by the firewall? Preferably using the ASDM.

We had an ASA 5510 as a firewall in our environment, and there is a requirement to access an ftps server from our location. Currently from the server location they configured everything by allowing our public ip to their server and gave the following details to access ftp.Please suggest which traffic needs to be allowed in our ASA to access the ftp server address as mentioned above. From my initial analysis, it's found that 989 port is also enabled for the access, but that was not mentioned by them.

View 1 Replies View RelatedThis question is in the context of servers sitting in a colocation environment behind an ASA5510 with security plus license.Our colo provider is going to be statically routing a /28 public subnet to our ASA5510 (say 1.1.1.0/28). We will also be getting a single IP (say 2.2.2.2/30) on a small router-to-router subnet (2.2.2.0/30) to which the 1.1.1.0/28 subnet will be statically routed to our ASA5510 from our colo provider.I will obviously set the outside interface of the ASA to be 2.2.2.2/30 so that the colo provider can route the 1.1.1.0/28 subnet to it. I will also set a default route to 2.2.2.1 which is the IP of our colo providers gateway (and the router that will be statically routing the 1.1.1.0/28 subnet to us).
We have various servers in the same rack as the ASA (connected via a 3750G switch). Some of these servers need to be exposed to the internet (web, email, etc servers) and some do not (database servers).I'm considering 2 different ways of designing the network but I have questions about both and not sure which way to go:
1) Scenario #1: Using NAT and private IP's for all servers.In this scenario where/how do I assign the internal network (say 10.1.1.0/24) and the public routed subnet (1.1.1.0/28)? I assume the internal 10.1.1.0/24 is an inside network assigned to the interface connected to the 3750G (to which all the servers connect). However, where do I assign the public routed subnet (1.1.1.0/28) since it is somewhat "nebulous" in that it has to reside somewhere on the ASA so that it can then NAT to the internal (10.1.1.0/24) IP's. Also, is it considered an outside or inside network - and on which interface? My confusion is that If its added to the outside interface then won't that conflict with the 2.2.2.2 IP to which the colo provider is routing our 1.1.1.0/28 subnet to? And if its on the inside interface connected to the 3750G then wont that conflict with the 10.1.1.0/24 private IP range of the servers?
2) Scenario #2: Using public IP's for all servers:This scenario seems more straightforward to me: I would want to assign IP's from the statically routed subnet (1.1.1.0/28) to my servers so that range would be configured as an inside network on the interface connected to the 3750G (to which all the servers connect). This would be configured on a specific VLAN (say vlan 50). I would then have another VLAN (say VLAN 100) on the 3750G that has a private IP range (say 10.1.1.0/24) so that non-public servers (database, etc) would reside on there. All public servers that need access to private servers would have a NIC on both VLANS (50 + 100). My question is is this the correct way of approaching this? I also like this because I dont have to worry about NAT and the ASA can act as a router/firewall and things are clear in terms of whats happening.
Ultimately I'm not sure which is the best way to go in terms of having all servers on a private IP range and just NAT to them (as per scenario 1), or implement scenario 2 where servers have two interfaces.The main thing thats bugging me from scenario 1 is I'm not sure where/how to assign the statically routed subnet (1.1.1.0/28) on the ASA? (inside? outside? which interface?).
I was enabling all the ports for testing on an asa 5510 and once I got to port e0/3 I got this error:
ciscoasa(config-if)# int e0/0
ciscoasa(config-if)# no shut
ciscoasa(config-if)# int e0/1
[Code]....
On the asa theres 4 ethernet ports 0 - 3 don't understand why port e0/3 is not listed. When a cable is connected the led's for that port goes green. Is the port just bad or is there a work around?
I have an ASA5510 and I would like to implement something like this: have two ports patched in and ready but only one active, the other one in standby (when the first one goes down the other port comes up and all the traffic goes down this way), all these on one physical box. So, it's basically like port failover on the same box.

View 1 Replies View RelatedI am trying to set up a Cisco ASA 5510 running 8.2 to allow a connection to a Polycom camera that sits behind it. What I want to do is forward multiple ports to allow a connection from an outside office. The polycom camera uses the following ports:
1720 tcp
3230-3235 tcp
3230-3253 udp
I got these port numbers from the Polycom web site. So what I did was create a service object as follows:
object-group service All-Polycom-ports
service-object tcp range 3230 3235
service-object tcp eq h323
service-object udp range 3230 3253 My question is how can I use this service object in a static (inside,outside)
command so that I don't have to create multiple commands for the port forwarding. Is this even possible or do I have to sit down and write out around 30 seperate commands to do this. I've been searching the web and it seems a lot of people want to do this but so far I haven't found an answer.
I've cloned the configuration off one of my ASA5510's to another 5510 to use as a template for a new data center deploy. I have configured the new firewalls networks and rules, and of course changed the WAN IP config to its new setting.
I want to test the firewall in y office before I deploy it. How should I configure my Macbooks ethernet configuraiton to test the firewall?, as I have tried without success to connect to it.
Let's say that my WAN configuration is 134.5.169.98/255.255.255.224 with a static route of IP address 0.0.0.0, Netmask 0.0.0.0 and a gateway IP of 134.5.169.97.
I've tried setting the route to force all traffic through the interface (sudo route add 0.0.0.0/1 134.5.169.98), but that did not work either. A trace route to the external interface IP of the firewall (or the external IP of an expose server) get's a "no route to host" error.
I've tried many configurations and have not been able to access the internal servers/services/VPN at all.I've also tried with a cross over, and straight through cables.
What should I configure my macbooks network configuration as so I can connect directly to the WAN port to test external access to the internal servers/services and test the VPN client?
Is it possible to have the same subnet on all of the endpoints of a hub and spoke VPN tunnel? I have to create 18 ASA5505 tunnels back to one ASA5510. Instead of having 18 subnets out there it sounds more efficient for my application just to have one. Sort of a CLOUD (there's that word) arraignment.
View 10 Replies View RelatedWe want to deploy a NMS (Network Monitoring System), in this case SolarWinds, to monitor devices we have deployed at the customer site. We will make an IP VPN connection (ASA5510 with Cisco 800's) to the customer site. We have one primary NMS installation running in our datacenter. This NMS has to have a connection to all customer sites. We run into a problem when two customers use the same subnet. We want to use VRF-Lite to solve this problem but I am stuck in my design.
I have attached "VRF.jpg" to show the (basic) design I have made. The connection from customer to the router in the datacenter is not a problem. We can put the fa0.1 and vpn interface in the same VRF group. Via one physical cable we will go from router to NMS in which the NMS has multiple virtual interfaces. The datacenter router will route between the 192.168.x.x (NMS) and 10.1.1.x (Customer).What I can't seem to comprehend is how the NMS can decide how to get to Customer 1 or Customer 2. The customer can reach the NMS one-way but the NMS has no way to reply back because if it replies to 10.1.1.1 it can either use interface fa0.1 or interface fa0.2.
Let's say I have 3 APs, all connected to a WLC 5508,Each AP has a computer that is connected to it, Computer A, B and C, all on the same Vlan with same SSID
Is it possible to configure so
A and B can not talk to each other but both can talk to C ?
Something like "protected port" feature in the switch world.
We are using catalyst 2960S Lan Base IOS on Radio towers. We just bought 50 Accest points, thas are GPS synchronized. Problem is the APs need to be connected on L2-mac betwen each other. But at this time we are using port isolation on each switch (tower) by protected port function to isolate clients from each other.
My question is, is possible to specifi a Mac addresses in specific vlan thats can comunicate betwen protected ports? On tower is one Master unit and others are slave. I thing there is only 1 dirrection comunication - from master to slave.
We recently reset a 4400 controller in a school. Although all access points associated, clients could not get the Internet. On investigating we suddenly lost connection to the web interface. We tried hyperterminal connections to reset, but found that the managament interface had the ports "unconfigured". We finally reset the configuration, and when we tried to start from scratch it now does not allow a port designation. It asks for 1 or 0 but says both are invalid when entered.

View 12 Replies View RelatedI've got an annoying problem with my ASA 5520.I have traffic going from the inside interface (security level 100) to the outside interface (security level 0) with a global PAT applied to the outside interface address for all inside traffic - and I can't seem to traceroute through the firewall.The ruleset is simple - basically, allow any IP from inside to outside. The NAT is simple - PAT all traffic unless exempted to the IP address of the outside interface.If I do the trace from my internet edge router it works fine - so I know it's not soemthing my uplinks are filtering - but if I do it through the firewall, I get perfect responses until the hop where it hits the firewall interface - then nothing.Is there something I am missing that I need to do to allow traceroute to just work with all the rest of the traffic?

Let me start by saying that I'm just starting to study for CCNA, so the ASA seems to be a bit above me yet. The ASA's we are using is for VPN to our corporate office and only allowing access to our Citrix environment, so no direct internet allowed. We have a person who works in the remote office who has need for a caption telephone that requires direct access to the internet. The phone only supports DHCP, and getting the ASA to do an ARP reservations is proving difficult. For now I wrote an access list to allow it's DHCP address out but it still isn't working. The access list I wrote is:
access-list 101 extended permit ip host xxx.xxx.xxx.124 any log
access-list 101 extended permit ip any any
access-group 101 out interface outside
When I do a show access-list I'm seeing that traffic is hitting the access list as the hit counter has increased. When I do a show conn I'm seeing one of the IP's that the phone should have access to, however the flags are: saA, so I'm assuming they are not getting a response. According to the manufacturer, only outbound connections are needed, no incoming ports required. All traffic is TCP.
I have 3 networks coming on DMZ (VPN) interface. Only one network is able to ping the DMZ interface. See below networks coming i on the DMZ.

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]

Because of this Skype attempts to use 80/443 which are sent to the proxy server but bnecause they're not HTTP/HTTPS they cannot be understood. Skype attitude is to open 1024-65535 which is just plain stupid!
There's no way to specify which port(s) Skype uses for outbound. I tried opening 33000-33099 which worked perfectly for 2-3 devices (Win laptop, iPad) but others failed all the time.I've seen people mention using an AIP-SSM module in the ASA for blocking Skype (and other things eg torrents). Is it possible to use this module to allow Skype eg on ports 1024-65535 whilst blocking any other application from using those ports?
Attached is our network diagram showing the details of our remote office and the corporate side which are connected via private fiber. The workstation (10.10.102.84) can ping the 10.20.0.31 IP address of the PBX but not the .30 address and I know if we can’t ping it we can’t remotely manage it. The 2811 router, ASA 5510 and the 6509-E can ping both IP addresses on the PBX. The ASA logs the error "Denied ICMP type=0, from laddr 10.20.0.30 on interface inside to 10.10.102.84: no matching session" when the workstation pings the .30 address.
We changed the default gateway of the PBX from 10.20.0.2 to 10.20.0.1 (2811 router) and we were able to ping both IP addresses from the workstation but the SIP trunks from the Internet stopped working (they NAT to the .30 address). Because calls may be forwarded from the PBX to the corporate network (via IP phones) we will eventually need to change the default gateway to10.20.0.1 and still need the Internet SIP trunks.
My two questions are, how do we resolve the issue of pinging the .30 address from the workstation and then when the time comes how do we resolve the issue with the SIP traffic reaching the .30 address when we change the default GW of the PBX to the 10.20.0.1 address of the 2811 router.
I have an ASA 5550 at our main site with an external ethernet interface to our ISP for internet access.

I'm having trouble identifying what IP address to use as the desitination for the permit rule for access to the internet. The rule that comes after the permit is to deny 10.100.41.x/24 access to internal network addresses.

Last week, however, we started having problems accessing one of our networks through the PIX, and after working with Microsoft, we determined it was an MTU issue. The maximum sized packet to the PIX and through the PIX is 1020 bytes, and it doesn't matter if the packets are sourced from a server or the PIX itself. From the server, we can ping 1500 byte packets to the core switch with no issues. All interfaces are set for 1500 byte.
View 1 Replies View RelatedI am having some issues with my ASA 5510 (running ASA 8.2) dropping ICMP unreachable-fragmentation-required-but-df-bit-set type messages coming in on the outside interface. I have the following entry in the ACL for the outside interface:access-list outside_acl extended permit icmp any interface outside and there are no other entries in that list that should take precedence and drop the packet. Pings from outside to the ASA work when this ACE is present and do no when it is absent so it is clearly taking effect. I see the following entries in the debug log when sending a large non-fragmentable packet (that would cause an intermediate router to send back this ICMP response) out to the internet through the ASa,As far as I can tell I am not running ICMP inspection; I don't want it to do any stateful magic here since the outgoing traffic would have been ordinary data from another protocol and would not have caused an outgoing ICMP connection to be built to match against.

I'm a college student working on a lab involving a Cisco PIX 501 Firewall.
My project involves 1 computer and a firewall. My goal is to use the firewall to allow access to the internet for that computer which uses a static IP 192.168.1.5 and ONLY for that IP address. The firewall is connected to the internet.
I have the computer hooked up to the firewall with the serial and using hyper terminal to enter commands. I think I need to use access lists in order to deny traffic on those ports for those particular hosts. I can't figure out exactly how I need to set it up.
What I need to do is permit internet access for 192.168.1.5 alone. Any other IP should not be able to access the internet.
I tried:
access-list 1 permit tcp host 192.168.1.5 any eq 80
access-group 1 in interface inside
I cannot access the internet using the computer with 192.168.1.5. The goal is to be able to access with that IP and no other.
