I am having some trouble configuring dual NAT on a Cisco 1841.
The 1841 has three interfaces. Fa0/0 - LAN Fa0/1- Different private network Fa0/1/0 - Connection to DSL modem
NAT overloading is configured on Fa0/1 and we have traffic that must be router there. We would like to have all internet access go through the DSL modem. Currently internet access is obtained through fa0/1 but is not ideal. I have floating static routes configured if the DSL link goes down. (Which is currently unplugged) I do not have physical access to the router at this moment. We would like to keep the config a simple as possible. It seems like route-maps may be one of our only options.
Basically I have an internet router (1841ISR) with 1 internal (LAN) connection and 2 internet connections. What I want to do is route specific traffic for 3 of my internally hosted services (smtp, https, etc) through one internet connection (fa0/0) and then route all other traffic through the unmanaged/dynamic IP ADSL connection (Dialer 0).
I'm working on setting up a template configuration for the Cisco ASA 5505 device that we'll use to configure more routers for various client needs. One of the requirements requested of me is the following: Internal hosts assigned a DHCP address are blocked from the internet Internal hosts with a static IP are permitted access to internet All internal hosts can communicate regardless of state
Now, I'm fairly new to this and I'm certain my terminology isn't correct so googling the problem has been fruitless. I have followed basic configuration guides and have configured the device to hand out DHCP addresses to hosts plugged in ports 1-7. If I'm plugged in and specify my address manually in the OS I am blocked from any access so I can only assume there is an access policy or some rule preventing me from authenticating against the router despite having set up VLAN1 to be the entire class C subnet. What sort of steps would I need to do to configure this? New access lists. For the record, the dhcp addresses are in the range of 10.100.31.64-10.100.31.95. VPN users are assigned an address from 10.100.31.220-10.100.31.240 and there seems to be no issues with that configuraiton. I don't wish to constrain what addresses a user can use should they specify a static IP (10.100.31.5 should be just as valid as 10.100.31.100).
I have a Cisco 1841 router at home with version 12.4(13r)T advanced ip services. The setup is extremely simple:
1) PPPOE dialer to my service provider over ADSL 2) Nat overload on the dialer interface. 3) 2 V LAN s one for home network (wired) and one for wireless both v LAN's are connected through interface v LAN s respectively.
My problem is when I configure static NAT to map RDP or any other protocol to inside hosts this does n`t work. " ip nat source static tcp 192.168.20.3 2222 interface Dialer1 2222 ip nat source static tcp 192.168.20.3 3389 xx.xx.xx.xx 3389 extendable ip nat inside source list 20 interface Dialer1 overload "
When I open wire shark and sniff the traffic on home computer which is the one I`m trying to reach I can't see any traffic. And While performing Nat debugging I am also not able to see traffic going to that port (for example 3389).
Does the 22xx Series FEX support static or dynamic LAGs between itself and a server?Imagine a server with dual 10G NICs, and I need to connect them to the SAME 22xx FEX....can I set up a LAG between the two 10G NIC ports and two 22xx FEX Host ports? Does it depend on how the FEX is connected to the parent 55xx?
I guess i am just getting old and forgot how this works, or i have an IOS load with an undocumented feature in it.A customer of ours wishes to have their exchange server appear to the outside world on a seperate IP address as their public pool address is.in the past this has not been an issue, however in the current configuration we are unable to get the source address to appear per the NAT statement it always sources on the overloaded IP. below is the relevant NAT config, am i missing something, or have i hit a IOS feature? [code] There is a 45% chance i have forgotten everything i learned on the NOC desk and a 50% chance that it is somethine really stupid and 5% IOS is broken
We upgrade our Internet service in our India office which required a new router. The local vendor suggested an 1841, so that is what we have. It has two fastethernet ports on it.
The ISP (Airtel) provided the following IP address information:
Public WAN IP : 122.181.23.200/30 WAN IP : 122.181.23.202SUBNET MASK : 255.255.255.252GATEWAY : 122.181.23.201Pri DNS : 125.22.47.125Sec DNS : 202.56.250.5
I'm at a FOX affiliate TV station, and in order to connect our EAS Device to the internet & Fox Splicer, I need to setup a Statio NAT, so we picked up an 1841 on eBay.
I've done a little configuration in HyperTerminal.
I've done these ip addresses:
FE0/0 10.1.10.13 this is the subnet our EAS device is on FE0/1 10.110.81.174 this is the subnet of the Fox Splicer.
I need to have NAT translate 10.1.10.11 to 10.110.81.170 and I also need to set a route for 10.110.81.0/24 pointing to 10.110.81.161
I have a switch that I have configured for jumbo packets, but they don't seem to be functioning. I have set system mtu jumbo 9000. The hosts are connected via 2x EtherChannel links. The hosts are jumbo frame enabled, and can ping their own local address using jumbo packets & do-not-fragment flags on the pings. They cannot, however, ping each other or the switch that way - it always says that the packet requires fragmentation. I know the attached machines (they're all VMs) and virtual switches support jumbos because I can ping within the virtual interfaces of the VMs. It's just traffic that goes over the switch that fragments.The switch is a WS-2960G-48TC. Here are the various outputs, with a section of config at the end.

I have a ASA5510 with 2 internal interfaces (inside1 and inside2 same security level) configured with OSPF for dynamic routing with 2 routers to corporate subnets. I have a server in a private subnet that needs to be accessed from Internet. So static pat is used in ASA with the command
As OSPF is in use, the subnet 192.168.1.0/24 may be reachable from interface inside2. When I tried to configure the static command for inside2,
static (inside2, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255.the error message came out "WARNING: mapped-address conflict with existing static...". Is this just a warning, or this is not possible in ASA.
Let's say I want to NAT 2.2.2.2 & 2.2.2.3 on wan interface to 192.168.1.1 on DMZ. I tried to add the static NAT with ASDM but got the following error:"The modified Static NAT Rule cannot be configured, as it overlaps with following existing rules"
Okay so I currently have an ISP that offers the standard "2 Dynamic IP's" and I'm wondering how to utilize this? The tech guy said I need a HUB...but I'm not sure what kind and where to get one etc. Secondly, even if I am able to get this second IP going, will they be entirely separate IP addresses? I need the IP addresses to be completely separate and untraceable to the same source. Is this the case or can you somehow trace back the two dynamic IP's to the same source IP? Will I need two different static IP's if I want the two connections to be entirely separate, unrelated, and untraceable from each other?
I am running an ASA with 8.4(3) and am trying to setup a dynamic VPN tunnel. We are having a business reason to establish a VPN tunnel to customers who do not have nailed down IP addresses. Now I found a number of documents that outline the steps involved. It seems the basic steps were to Establish a regular tunnelAdd dynamic crypto mapAssign the dynamic crypto map to the tunnel created under step 1. While this sounds pretty straight forward and simple, while prepping for doing just this I hot a road block while thinking it through. In order for my ASA to put anything into the tunnel it has to have a route to the remote network pointing at my VPN peer at the end of the tunnel. How do I do this in a dynamic tunnel? How do I add a dynamic route so the ASA knows which tunnel to stuff the traffic into? How do I stop the traffic from just being send to the Internet?
Trying to connect a 5505 with a dynamic address on 8.3(2) to a static IP'd asa (5510 on 8.2(1) with a DefaultL2LGroup and dynamic maps already created.
Inside networks: Local (5505) 192.168.100.0 /24 Remote (5510) 10.100.1.0 /24
My dynamic ASA is trying to use a Cradle point 4G connection to a head end ASA-5510. The remote end with the Cradle point 4G is not even initiating the tunnel! I need another set of eyes. it was initiating the tunnel last week but not completing the connection. Now its not doing anything. i am going backwards. Below is my remote ASA config.
ASA5510(config)# sh run : Saved ASA Version 8.2(2) host name ASA5510 enable password 8Ry2YjIyt7RRXU24 encrypted password 2KFQnbNIdI.2KYOU encrypted names [code]...
I have a laptop directly attached to the inside interface. The PC and ASA can ping each other. The test interface is the one I am trying to use. Does my default route need to point to 192.168.0.1? Or is the remote peer correct? I thought the remote peer was correct? The 4G modem is like a pass-thru device. If I connect my laptop to it I can get out to the internet.
I've deployed L2L VPN between ASA's dynamic to static in a hub and spoke format.Everything works great if you are on a spoke ASA and you need to go to the hub but you can not go from the hub to spoke.
I'm using ASA code version 8.4(1) ... Below is what I have so far...
I have 2 computer connected and both have dynamic IPIf I change one of my computer's IP from dynamic to static Will it be okay to another comp ? ( Can it still connected to Internet / LAN )
i need to change from dynamic IP to Static for work, Iv rang my provider talk talk and the only way i can do this is go to a buisness line and pay more a month is there anyway i can log into my router and change from dynamic to static myself? im not on about the IP thats starts 192.blah blah blah its the one where u go somewhere like whatsmyip.com mine is dynamic as it changes if router is reset, there is hiccup in internet or computer is off for the night etc...
I have a few 3560E running Ver 12.2(50)se2. Can these boxes be configured to run VRF. I see a "sho IP VRF" option, but I do not see it available when under config t. Do I need to do a IOS upgrade to be able to configure VRF?
I faced up with a strange configuration issue at my 2811 router running IOS C2800NM-ADVIPSERVICESK9-M, Version 15.1(3)T. The configured Dynamic and Static NAT do not work (users can't go out to Internet and can't reach internal services via external IPs).The configuration seems to be very simple (one internal and one external interface, one address for dynamic NAT pool, and only few static translations -- see attached file).
Recently we migrated our network to ASA 5515, since we had configured nat pool overload on our existing router the users are able to translated their ip's outside. Right now my issue was when I use the existing NAT configured to our router into firewall, it seems that the translation was not successful actually I used Dynamic NAT. When I use the Dynamic PAT(Hide) all users are able to translated to the said public IP's. I know that PAT is Port address translation but when I use static nat for specific server. The Static NAT was not able to translated. Any conflict whit PAT to Static NAT?
All outgoing connection from IP1_PRIVATE and IP2_PRIVATE should be natted to IP_PUBLIC and all incoming connection to IP_PUBLIC should be forwarded to IP1_PRIVATE: is it correct ?
I just switched from a Linksys Router to the RV215W, I was able to put custom dns servers for my wan, ie. opendns, but now in cisco, I'm missing this feature.
Does any one know how to set-up a workarround with DHCP from my ISP and access custum dns servers..
When are we gonna have this feature implemented in the WAN secction.
Is it possible to configure a Site to Site VPN from a SA520 with Dynamic IP (DSL) to a Cisco ASA5510 with static IP? I need to make sure about because i am trying to sell this solution to a customer with two branch offices with DSL connection and a Main Office with Metroethernet.
I know that using a a pre-share-key on the defaultl2lgroup of the ASA, the ASA will accept any site to site VPN. I have tried this with the ASA 5505 instead of the SA500 for the branch office, but the ASA5505 is too expensive for my customer.
we are running 8.4(2) on the asa with the below configuration we basically have a static for .7 on .25 and a nat for .7 for port direction with manual nat that takes precedense over auto nat within the object group am I correct that I dontneed the dynamic statement and that its redundant?
I need assistance regarding changing of DYNAMIC WAN IP to desired WAN IP to connect my e-mail server of my office, Problem is :i have a dynamic WAN IP at my home internet router , and my e-mail server at office only allows assigned WAN ips to connect , I want to connect from my home, i know the WAN ips which are allowed to connect my e-mail server and i want to change my dynamic wan ip virutally to desired WAN ip for incoming and outgoing traffic from my wireless router, What I need to do :I need to change my dynamic WAN IP to an static desired ip at my wireless router?
I have the dir-601 as my main router. Its IP settings are dynamic, not static. My second router, the router I'd like to use as the access point is a Belkin Wireless G Mimo. My goal is to setup the Belkin as an access point downstairs away from the main router. I'd like to do this wirelessly. I'd like to phsycialy plug devices into the Belkin, while the Belkin receives access to the internet wirelessly from my main router, the dir-601.
Here's my issue. There's an easy option to use the Belkin as an access point. So I do this and set the Belkin router to an IP outside the DCHP range ( currently 192.168.0.100 - 192.168.0.199 ) to 192.168.0.250. My dir-601 will only recognize the Belkin access point while plugged in physically. I know this because when I did a ping test it only see's the Belkin when plugged into the dir-601 via ethernet cables. My ultimate goal is to simply set the dlink dir-601 to recognize the Belkin as an access point.
We have a working PBR route map on a 6509 switch and a 3750 switch, each in different locations.On both devices, the route-map is configured to match on one of multiple ACLs, then set the next hop to a directly-connected IP address, like so: [code]
When copying in the ACL contents for "ACL20", they were accidentally copied in to the ACL1 list, and ACL20 was never created. Shortly after this was done, the next hop router went unreachable in both locations. Pings failed and the 6509 and 3750 each lost the EIGRP adjacency to the 1.1.1.5 router. After troubleshooting, I removed "match ip address ACL20" and connectivity returned.
My question is...if a PBR route-map tries to match on a non-existent ACL, what happens? Does it mark the next hop unreachable (even though it's directly connected) or does it match for ALL traffic and send *everything* there (thus, making it appear unreachable, as if a broadcast storm was happening)?
