Cisco Routers :: Srp521 Port Forward Based On Source Ip
Dec 20, 2012I have a customer with a Sonic wall that I want to replace with a 521.He currently has port forwaring setup so that only 3 ip addresses can access the port forward. Everyone else is dropped. Is there a way to do something similar?I can make it work for a single one via the DMZ tab with a source ip address. but there is not a way I can find to add the allow for the other two remote connections.

Dec 27, 2011I have one public IP address but multiple local servers that run on the same port. I cannot change the port the clients use to connect to this server, so I can't do a port map in my NAT router. The solution I had in mind, is to filter on source address. If a client from public IP X.X.X.X connects to port Z, I want it to go to internal server 10.10.10.10 and if a client from public IP Y.Y.Y.Y connects to port Z, I want it to go to internal server 10.20.20.20. Is this possible? I'm using an ASA5510 but I could also switch to a 5505 for this.

Dec 16, 2011I have a nat statement to nat a subnet to a host address. Only the host address is allowed to traverse the VPN. However when I use a route map to do this, I cannot see NAT being performed and my VPN does not come up. When I use a static NAT for a 1 to 1 host translation I can see nat being performed and the VPN comes up. Using the route map method, the other party said our source IP is 0.0.0.0 0.0.0.0.

Jul 24, 2011I have a situation which requires some non best practice stuff to be done. There is a box behind an ASA that has a lot of code that references public DNS names and therefore needs access to itself and a number of other boxes on the same subnet via the public DNS names (that obviously resolve to public IPs). This traffic is dropped on some pretty fundamental ASA characteristics.I know this isn't really ideal, and it should be handled by DNS nstead, but I'm in somewhat of a bind and need to know if the ASA can allow this traffic.I figure I could match the traffic and exempt it from state-checking and that would probably work, but it's not a very graceful solution.

Aug 22, 2011Every year I attend a local motorsport event and I am usually responsible for providing a live online video broadcast of the event which I do using a website such as ustream.tv or similar. The event is non-profit so spending as little money as possible or none at all is the best option for us. We use a 3G card/dongle and a laptop with 2 or 3 webcams for the video feed....The results/scoring system in use at the event is controlled by the organisers and they have setup a VNC server where teams can connect with their laptops via a wireless network to view results, what I would like to do, is to include the results screen in my video feed. So somehow, I need to trick my computer into thinking that the VNC viewer software is a video input device.I have looked for something similar last year but didn't have much success, If separate laptops are needed, I have 3 windows laptops at my disposal and a macbook pro which will be on the same network. Whichever one will be most suitable for the task will be used.

Cisco WAN :: 881 - NAT Not Working When Source IP Is From LAN
Feb 22, 2011I have configured my Cisco 881 and it is quite stable but now I am working on some minor details.
I have several Public WAN IP addresses which are NATing to internal web server. When I go to the WAN IP at port 80 from the Internet, the NAT works fine and it maps perfectly to the internal Web server. However, when I try the same same WAN IP from the LAN which contains the web server, the Router blocks the traffic and I get nothing back.
I have verified that I can get to the Inernet from the LAN but it seems that I cannot go bfrom the LAN to the Internet and back into the LAN via NAT.

Mar 5, 2012So I use Shaw as my ISP, with the dlink DIR-655 as my router.Originally I was using the DPC3825, and started noticing some nasty signal fluctuations on my phone and wii (would go from 5 bars to 1 bar, causing netflix to drop out, games to disconnect, phone browsing to stop completely, etc) which is why I bought the DIR-655. I have been looking for sources of RF interference.I do not own a microwave, all the electrical work in this house is brand new, I have no neighbors (live in middle of a forest). I have tried positioning, every wifi channel, building an aluminum satellite dish to direct the signal where I want it to go. I've had it in every room in the house, I've unplugged the fridge and all other RF electronics (cordless phones, etc), and the issue remains.
So what the heck is going on here? Does my house hate wifi signals?I was thinking maybe dirty power, but my house has emergency power batteries that run 24/7.

Cisco WAN :: 3750G / How To Identify Source Of Runts
Aug 27, 2012I am getting input errors/runts on 2 of my gigabit interfaces that connect to our WAN service provider's network. In relation to total packets, its not a large number, so its probably not a big deal, but I'd just like to find the source so I stop seeing the errors in Solarwinds. Our service provider says that they don't see any errors on their side, but the errors are incoming to us.
I've tried to capture the traffic with Wireshark, but discovered that often these packets are either discarded or padded by NICs so Wireshark will not see them, or at least will not see them as undersized.
Is there any other way I can capture these packets so I can find the source and figure out how to stop them? Our equipment is 3750G running 12.2(55)SE. Its not a trunk port. I know there was a bug in prior IOS that would cause some frames to be marked as runts even though they were forwarded successfully.

Cisco Firewall :: ASA 8.4.3 - Does It Check DNS Source IP Address
Oct 29, 2012Does ASA 8.4.3 check the source IP address of a DNS reply and drop it if the reply address is different to that in the query?
Customers DNS server does this due to a recent change, their server now has a virtual address, but replies are sent from its physcial address. This is temporary. Their PIX is happy with this.
Replace the PIX with the ASA, DNS fails, the only reason I can see is due to the way their internal DNS operates.

View 3 Replies View RelatedRecommended Open-source Firmware For ASUS RT-N16
Nov 27, 2012I have recently acquired an ASUS RT-N16 router. My original plan for it was to install Tomato on it. However, after checking their website i found out that the firmware was not updated in the last 2 years. There seem to be a few updated mods but none of them really seemed mature/stable/well-documented.
I would like to know what other people recommend as open-source firmware for this router. I know the answers will probably be subjective; so i will give a bit of background on my needs:
for now i will only use the Wi-Fi on an Android phone the connection will not be shared with anyone (so QOS is optional)i want a stable (wired) connection on my PC (for online gaming etc.)i want the (wired) download/upload speeds to be as close as possible to those achieved by directly plugging the Ethernet cable to the PC's network card; i have a 100 Mbps connection my ISP uses PPPOE my technical level: i am a software developer and i have good knowledge of bash scripting, but no experience with networking
Also, i know that i could probably just use the stock firmware (and maybe will use it for a while), but i'm interested in trying an open-source version (for more features, flexibility, as a learning exercise etc.)
Cisco Firewall :: Source-PAT Outside Traffic Through PIX525?
Feb 22, 2013I have been tasked with building a vpn tunnel with a partner company between our company's PIX firewall and the other company's ASA's firewall. The traffic flow will be Partner A company users will be accessing my company's Citrix server. I want to source-pat the partner company user traffic to my company's PIX inside interface as it enters my LAN to access my company's Citrix server. The partner company will be PAT'ing their user traffic to a single ip address - let's say for discussion purpose it is 68.108.244.25. So there will be site-to-site vpn configuration and nat configuration required to be performed to enable this traffic flow according to the above requirements. I am comfortable with the site-to-site vpn configuration tunnel so I don't think it is necessary to post this portion of the configuration to be reviewed by this form. What I do need is NAT portion of the configuration.
{My Company's Citrix Server} ---------<inside ifc>-[PIX525]-<outside ifc>--------(internet)------{Partner Company A host PC's}
10.100.12.103 68.108.244.25
My proposed configuration to enable nat'ing (or pat'ing) Partner A user traffic to my PIX firewall's inside interface is the following:
global (inside) 9 interface
nat (outside) 9 access-list PartnerA_source_nat
access-list extended PartnerA_source_nat permit host 68.108.244.25 host 10.100.12.103
Cisco Firewall :: ASA 8.4 With NAT Source Address Translation?
Dec 5, 2012I have a server in a DMZ of my 8.4 ASA with nat:
object network FTP-SERVER
host 192.168.1.102
nat (dmz,outside) static interface tcp ftp ftp
And that's working well. However, I now need to translate the source address of connections from the outside to the FTP server as well. The aim is that the source address of packets when they reach the FTP server is an address on the DMZ subnet (as the default route for the FTP server now needs to be something else, not the ASA) as well as this outside-dmz NAT. I thought overloading the DMZ interface of the ASA? Or another IP in that range?

Cisco AAA/Identity/Nac :: ACS 5.3 Limit AAA Authentication For Certain Users By Source IP
Jul 1, 2012we have TACACS+ based AAA on our network equipment, authenticating against internal user database on a network of ACS 5.3s.What I want is to limit certain AAA users (namely automated tools) to be only permitted to authenticate from a list of known IPs.I can do this for authorization, easily, that isn't a problem. The problem is to only accept authentication attempts coming from certain IPs and ignore the rest. My problem is, as it is currently, the automated tools are prone to a sort of a DoS attack - if I attempt logging in to any device using the tool's user account and a wrong password, I can get the account disabled in five tries.
I want to ignore all authentication attempts, unless they are coming from well known source IPs.Ex: netmon user is the user for a tool running on server 10.20.30.40. If I try to log in from my own laptop with user netmon, it should fail, and the attempt ignored. Currently after five (or whatever is configured) failed attempts, the user will be disabled. Oly attempts from 10.20.30.40 should be considered for user netmon.I can't use ACLs on the devices, as I want other users to be able to log in from other IPs.
