• even host multiple NATs

  hub 3030... I have a local host that needs to access the L2L multiple tunnels with different requirements of NAT:

  I currently have that configured NAT...

  source destination of 134.x.x.x/32 the NAT static 10.1.1.1/32 ANY

  I need to configure the NAT...

  source 10.1.1.1/32 static NAT 10.99.17.x/32 destination 32.x.x.x/32

  Is this possible?  I tried and I get "Source and the address of the remote network.

  conflict with an existing rule.  The source or the address of the remote network

  must be changed. "  This is the conflict because of the destination of ANY pre-existing rule?

  I thought that, since the destination of the rule I have to add is more specific than that

  should work.

  Thanks for your help, Anne

  Hi Anne,.

  Yes the conflict error that we see is due to the pre-existing State OF destination. Ideally, we need to have more specific static instructions in static rules to have several nat for the same source. So I would say that we find out the list of remote networks for which we need the 1 translation (134.x.x.x/32) and apply the static rule (may need more than 1 static rule if several remote subnets are the case), and similarly a plus for the new static we are looking (for the 32.x.x.x/32 destination).

  Now on some of the other safety devices, we have a work around for our scenario, but I do not know if the version of the software running on your hub it would support.

  Try to remove the static rule to all (1st statement) and then apply the new rule first (to 32.x.x.x/32). After that, apply the original static rule (destination at all). The idea is to have more State static speific first, and then the General static (all) the rule for the rest of the destinations. I suggest you try this in a maintenance window to avoid any impact on users.

  Let me know if that helps...

  See you soon,.

• Multiple NAT Outside beaches?

  HI -.

  I hope someone can advise me if this scenario is possible.

  Here's my situation. I just installed a second WAN link and a border router additional ISPs to double-House using BGP. To facilitate the management, we will use one of the 2 24 we control now, however one that we will use later, the new block comes from the second ISP, which means of course go through a change of ip address.

  I try to avoid a plan where I have to change all the public IP addresses on a weekend, due to the amount of the different VPN and other specific IP connections than other organizations have with us, while I was trying to plan a gradual passage.

  I have a single 515 (6.3) for outbound traffic, and add another is not possible for about 6 months (lease is expected to return for the time in which we will go to the ASA). Finally addresses outside the firewall will be a single/24 network, but in the meantime, I would use the two lines (using NAT) on the firewall.

  By design, the GW for the firewall is currently concert port on the original router. This router is using the static routes for the trafficking of exit and entry to our ASN, but the newly installed router is using BGP. Before I turn BGP on the original router, I have a show a connection between the two and I want to implement based on routing strategies to define all traffic from the new/24 range with a next hop for the new router BGP running.

  I tried yesterday, and I had no connectivity even ping on the edge router using this new set of IP addresses. Is it possible to implement these two ranges of IPs for NAT on the firewall and have the two lines at the same gateway IP address.

  I know it's probably confused, so if you need clarification in any field, let me know.

  Thanks for your help.

  I don't see why it would not work as long as you have control of the config of the outside PIX next hop router. Set up the first subnet as usual, then get your second subnet at IP of PIX. Implement the NATs on PIX as you wish. On the gateway router you need to establish routing strategy (map of the itinerary) so that it uses an ACL to look at the source IP address coming from the PIX, routes an ISP, second rate would vary other ISPS.

• Multiple outside NAT at the same internal IP address

  In my view, the answer is no, but wanted to check.

  Can I have multiple NATs on the same interface to a single internal IP?

  For example.

  static (inside, outside) a.a.a.2 10.20.30.248 netmask 255.255.255.255

  static (inside, outside) a.a.a.3 10.20.30.248 netmask 255.255.255.255

  Where the subnet and the IP block is also on for two external NATs.

  Hello

  If you try to do the following:

  definition of the IP 10.20.30.248 to a.a.a.2

  and

  definition of the IP 10.20.30.248 to a.a.a.3.

  Learn to translate the internal ip address to two external ip addresses. If Yes, then this is not possible.

  I hope this helps.

  Kind regards

• RV220W: Field of Destination Internet IPv4 firewall rule

  The manual States:

  This gateway supports multi-NAT, and the Destination Internet IP address does not necessarily have to be the WAN address. On one WAN interface, multiple public IP addresses are supported. If your ISP assigns you more than one public IP address, one of them can be used as your main on the WAN port IP address and others can be assigned to servers on the LAN or DMZ. In this way, the LAN/DMZ server is accessible from the internet by its public IP address to aliased.

  My IPS gives me 5 IP addresses (say x.y.z.1 - 5) I can use. My WAN interface has address x.y.x.1

  So, I thoughtInternet Destination meant I can do rules like:

  Allow SMTP and dispatch to destination of 192.168.1.a and internet internal address is x.y.z.2

  So, I thought I could do multiple-NAT-transfer as in

  x.y.z.2:25-> 192.168.1.a:25

  x.y.z.3:80-> 192.168.1.b:80

  But this seems not to work at all.

  Have I misunderstood things here? CAN I have only my WAN IP port forwarding. If I want to use multiple servers inside I need to fully expose to the internet or they can do all their traffic through my WAN IP?

  If implemented correctly, from traffic

  Via 1-to-1 NAT must be protected by a firewall similar to

  traffic flowing through the WAN IP of the router port forwarding. Exposed to internet via the Port Forwarding and NAT 1 1 computers should be protected by the firewall's stateful packet inspection mechanism.

  To use NAT 1 to 1, you would need multiple public addresses from your ISP.

• multiple clients behind a NAT IPSec

  In our head office, I have a Pix 515e which acts as our VPN server.

  Several clients at a remote office are requiring VPN access to the corporate network, but can only connect at once. If a second connects the premiera is abandoned.

  I suspect that this is because they are sitting behind a Natted router and all share the same public address.

  When I was installing all first the VPNGroups I read an article that has discussed this problem and offered a solution, but I can't seem to locate it. Is this possible on a 6.3 (4) Version FOS Pix

  Denny,

  Sounds to me that you must enable (on your PIX, config mode):

  Let me know if this helps and if she please post rates as if you need an explanation on the NAT - T then let me know.

• IP NAT Inside multiple ISP

  Hello

  I would ask if I have 2 IP address from the ISP 1 and 2 of the ISP block, I have 2 inside the NAT map to 1 a web server, lets say:

  100.0.0.10 (ip ISP 1) and 200.0.0.10 (ip 2 PSI) to map on my web server.

  My question is, lets say I have 2 default route (0.0.0.0/0) for both my ISP. How can I do plan road so if the customer comes ISP 1 and access NAT to my web server (100.0.0.10), then the response from my web server will return to isps1 and do not use ISP2?

• (semi-urgente) RVS4000 and multiples (same port) NAT'ing

  Hello-

  I have a customer who has an Internet connection and 2 SMTP servers internal different.  Is there a way to NAT public mail/SMTP for each of them?  We have two periods of public inquiry.

  Thank you

  Hello Jeff,.

  Unfortunately the RVS4000 does not support one to one NAT. This limits the router to only be able to use one of the IP addresses that you have.

  If you are interested in a router that supports this feature, I recommend one of the following conditions:

• Dynamic Source NAT for multiple POOLS

  I'm dynamically creating Source NAT with a few pools and Access-list to be translated according to the access list. However, when configure some ACL do not anything. And the ACLs don't "corresponds to" No. I know it would be the right way to apply the ACL at interface with 'ip access-group in and out', but in this case would be impossible to apply an ACL with ip access-group command.

  FurthermoreI tested to the creation of a roadmap named TEST with all the ACL; but impossible to create all the «ip nat inside source road-map...» "with the same name of the road-map. Also check the cisco example: http://www.cisco.com/c/en/us/support/docs/ip/network-address-translation... ...

  Set the configurations.

  I need your help

  Thanks in advance!

  I know that common sense would be to apply the ACL on interface with "ip access-group input/output" However in this case would be impossible to apply an ACL with group-access ip control.

  This would not be the right way. An acl applied to the interface is only for filtering of the traffic through the router.

  Try to remove the keyword "log" of your ACL and retest.

• Questions about the allocation of multiple NETWORK cards in a machine virtual Windows XP Machine HOST/NAT or bridged?

  Hi all

  That is the situation. We have a Machine physics WindowsXP with 5 CARDS, all with static IP. Only be connected to the internal network without physical Internet connection is used.

  Map NETWORK 1 has a 10.34.78.241/255.255.255.0 IP Gateway 10.34.78.2

  Map NETWORK 2 has an IP 192.168.22.242/255.255.255.0

  Map NETWORK 3 has a 192.168.100.241/255.255.255.0 IP

  Map NETWORK 4 has an IP 172.27.254.240/255.255.0.0

  5 NIC has an IP 192.168.242.10/255.255.255.252

  I used VMWare Converter Standalone to do a P2V PC, which works well with the latest version of VMWare Workstation. All were brought to the course successfully. The virtual machine has 5 Networksas by the XP Machine of origin.

  I built a Win7 Machine with 5 physical NETWORK interface cards, I suppose to replicate the Windows original XP Machine, I need configure the static IP address of the new NICs as shown above and configure cards NETWORK the VM 5 HOST mode and use the virtual network Editor

  to adapt the VMS NICS? Or is there a better way to do it?

  Cheers for any help and advice that can be provided...

  If I'm wrong, you should be able to create a Bridged (vmnet) network for each physical card. Make sure that one (which is created by default) is mapped to a physical NIC dedicated rather than automatic.

• NETGEAR AC1900 R7000 several Xbox those open NAT Type

  Hi all

  What is the best solution for those multiple Xbox on the same network. I have two Xbox.

  My question - get an open NAT Type on both those of Xbox. Both systems have a NAT open but not for multiplayer games. More specifically, black ops 3. I have UPnP turned on, but my black ops 3 nat type is moderate. When you look at the list of UPnP, I see a port for Xbox Live service in the list as 3074, but black ops 3 requires the port UDP 3075. At the same time, 3075 UDP has been registered for one of my Xbox and now it is no longer the case. So, what I have to do is setup port forwarding and add only my IP address of the Xbox as a personalized service with the port UDP 3075 and it works. That's fine and all, but my IP address for my Xbox (both) will not change from time to time. I thought UPnP would take care of this for me.

  How should I handle this so that both those Xbox use the port UDP 3075 and I don't have to worry any change my IP? Or need to be updated for my router to Negear as Black Ops is no longer using port 3074 Xbox Live?

  I'm on the last update of the firmware as of today (November 9, 2015) of V1.0.4.30_1.1.67. Yet once, I thought active UPnP would solve my problems with Xbox runing both on the same network.

  Your ideas/suggestions are appreciated! Thank you for your time and help in advance!

  p.s. I want to summarize... I have a NAT open for two small Xbox (if I go to the Xbox a settings/network settings tab), but I'll get one Xbox, one with an open NAT and the other with a NAT moderate when you play multiplayer on black ops 3. Treyarch said they use is no longer the same port as Xbox Live, now they use port 3075.

  Hope this makes sense... Please let me know if you need more information or have any questions.

  You can keep changing IP addresses using the address book. Log in to the R7000. Go in ADVANCED > Setup > LAN Setup. Inside will be the address reservation section. Add two entries to your Xbox.

• EA6500 multiple IP addresses on the Internet interface

  I have verizon fios business with 5 static IP addresses and am set up for ethernet wan. I can use EA6500 as the router instead of use the own router to Verizon, but I can't understand how to assign every 5 static IP on the internet interface addresses. I have already affected the first IP address in the Web interface, but don't see a way to add multiple IP addresses internet interface or NAT section where I can create static NAT.

  Is it still possible with EA6500? If so, how?

  I don't think it's possible, given that the router support 1 address static IP at a time.

• EA6500 NAT several IP addresses

  I currently have my EA6500 behind verizon fios router. I have 5 static IP addresses to FIOS router, however the machines that I want to connect are behind EA6500. It is a double NAT scenario:

  Public network 192.168.2.0/24 network 192.168.1.0/24 - EA6500 - FIOS router - IP-

  What I want to do is for each public IP address, I would like to forward the traffic to a particular host on the 192.168.2.0 network. I can easily configure static NAT for FIOS router and assign internal IP (of 192.168.1.0 range) for each public IP address. However, I don't see a way to assign multiple IP addresses of 192.168.1.0 network to internet interface EA6500.

  I don't want to use EA6500 as a bridge, because it will reduce my EA6500 well enough to a very expensive GigE switch.

  Is this possible? Or should I replace it with something more useful as a router to the company? That's my house, so I would avoid buying a router for the expensive undertaking.

  Hi, the router only supports a static IP Configuration. I suggest you call the number of commercial company Cisco hotline to help you get a router more suited to your needs network, 866-606-1866.

• RV082 multiple subnet and DHCP

  Hello

  I want installation 2 lans in my RV082:

  192.168.1.0

  and

  192.168.2.0

  My question is what happends as DHCP?

  I tested and it gives only IP via DHCP addresses in the 192.168.1.0 lan. What happens if I put a WRT54G2 DHCP service in the Lan 192.168.2.0 and connected to the RV082?

  So, in this case the multiple subnet are useful?

  Thank you very much

  Oliver

  In general: the RV082 is now part of Cisco Small Business, and you might want to ask your questions in the Cisco Business little community support for routers. You will find people from Cisco over there...

  It is my understanding that the function of multiple routers RV LAN subnet extends the NAT tables. By default, the router of RV will be only NAT for source from inside the LAN IP subnet IP addresses. If your router is equipped with the 192.168.1.1/255.255.255.0 by default then it will be only to do NAT for 192.168.1. * IP address, but not others. If you connect a different LAN (for example, 192.168.2.0/255.255.255.0) subnet across another router (the one without NAT) to your RV then the different LAN subnet would no internet because the RV does not know the LAN subnet and it doesn't NAT. basically the RV would send source IP addresses * 192.168.2 unchanged in the internet where they would quickly disappear. The function of multiple subnet allows you to say the RV that 192.168.2.0/255.255.255.0 is actually a subnet of your local network, routed and is supposed to happen by NAT.

• WRT160N V2 multiple PPTP connections

  Hello

  I have a problem, try to connect multiple computers to a PPTP VPN.

  I have a WRT160N connected to the internet with the option of Automatic Configuration - DHCP

  2 computers behind the router to get IP from the router via DHCP

  I can connect to a computer, without any

  problems.

  When I try to connect with my second computer freezes just the connections.

  I read it has todo with GRE packets, or almost, I'm not an expert in network so

  This information is enough for me, my questions are:

  1 - is it possible to use this router and have more than one connected computer

  to the VPN?

  2 - If not is there any other wireless router I can use to fix this?

  Any help will be greatly welcomed

  Thanks in advance

  Tonio

  It depends on. It should be possible to connect to two different PPTP servers in the internet.

  It is not possible to connect two computers on the same PPTP server via a NAT router. This is simply because the router should dig a lot deeper in the GRE to distinguish traffic Grateful for two client connections between the PPTP server and the router's public IP address.
