Get Multiple Public IP Address From The Modem Using Switch?
Jan 25, 2013
My ISP assigns IP's through a standard motorola cable modem via DHCP server. I can pay extra for a persistent IP which uses the MAC of my switch and assigns an IP. Is there a way to get multiple public IP address's from the modem using a switch?For example. Can I plug the modem into the switch and then plug a computer server into the switch and get an IP assigned to that servers MAC address and then also have another server attached to another port on the switch and get a different public IP for that servers MAC address?
I have a i-ball 150M wireless-N ADSL2+ Router device in that , in the NAT tab, i have activated DMZ at my static ip with a private address 192.168.1.224 , so that that ip enabled device can be access to anywhere in public network.I want that using this single static ip , How to configure two private address devices in DMZ, so that both of ip enabled devices can be access in public network.
I am having 5 IP addresses assigned to me. I have one commercial/business modem/gateway/router. If I want to have the advantage of separate lines (go with this for now) how else can the gateway do it other than simply passing the IP directly through, no router function, basically a modem/switch, everything else not there.
I have Zyxel Modem configured in bridged mode with static IP from ISP. I want to connect multiple PCs to modem via switch so that each PC use the same configured Public IP address to use the internet. For this (generally) I would need to configure NAT for that IP. But I want to know that will it work under bridged mode or not?
I've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.
we need to implement a scalable solution where we can provide for each customer it's own public IP so that they can access some content restricted by IP range.the solution consists of a proxy software that will "listen" to multiple IP's, then reroute the HTTP requests and rewrite the URL's to a different format.Anyways, we came to the conclusion that what we need is the following:
- broadband line with a pool of 8 IP's - a router that can support multiple IP's - a server
what kind of router or device is required for this kind of configuration. basically the network diagram will be like this:
Internet ----> broadband -------> cable modem ------ > multiple static IP router -------> server NIC
we should be able to add the same above combination once we run out of IP's, another broadband line, another device and server ...
I've replaced my dead ASA5505 with a 861-K9.Our ISP provides a subnet of public address /29 (wan side) by example: 200.200.200.xxx /29,we have 3 servers (lan side) in the example 10.1.1.xxx /24 is the same case than Johnatan, the only difference are the public addresses. [URL], everything is ok when NAT via the FE4 public address, but when do the same with other public IPs doesn't work.
For a branch office we have an ASA5505 connected to the ISP with an DHCP provided public IP "locked" to the local MAC This works ok!Now - the ISP may provide up to 5 public IP's (all DHCP assigned).Is it possible to configure 2-5 public interfaces in the ASA?? As IP's are DHCP assigned there must be something (a interface) to request the address.Would this be possible, and if so - what license would be required??NAT routing on the inside should be possible as well.
At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 24.244.208.101 would be assigned to LAN port 1, 24.244.208.102 would be assigned to LAN port 2, and 24.244.208.103 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?
Is it possible to have multiple public IP addresses that are from different subnets going through one router? I have been told that this is not possible with most routers and that I would have to spend a lot of money on a router to be able to do it. I am still not totally clear on what defines a subnet even after reading up on them. What I am trying to achieve:
-My office has 10 computers.
-All would be connected to one router.
-My internet service provider has provided me with 10 public IP addresses, that are all very varied (which I asked for)
I would like to configure an 877w I just bought. It's connecting to a UK ADSL2+ link.I'm a penetration tester and I want to put the Cisco router in front of my existing firewall which has an IPS on it, so that it doesn't get in the way of port scans and vulnerability scans. My ISP has issued me with 14 usable addresses a/240 subnet and basically I want to be able to use the route with just the public IP addresses. I have configured Cisco routers before, but never with this type of configuration. It's always been single public IP address NAT'd through to one or two internal LAN's.
It will be nice if I could assign the wireless and fast ethernet ports to the same VLAN using the public addresses. I don't want to use DHCP I'm quite happy statically assigning IP addresses to the computers wireless and LAN interfaces. I am reasonably certain this is possible because not sure how to do it and a little busy at the moment carrying out penetration tests.
I have ASA 5520 with Ver 8.2.Outside interface is directly connected to ISP's router(TelePacific) and is assigned one of public IP:198.24.210.226.There are two servers inside the network with the private IP's:192.168.1.20 for DB Server, and 192.168.1.91 for Web Server.I did Static NAT 198.24.210.226 to 192.168.1.20 and 198.24.210.227 to 192.168.1.91.When I access DB Server(198.24.210.226) it's working OK but when I access Web Server(198.24.210.227) there is no response at all.I checked the inside traffic, it even did not get into the firewall.Is this the problem with ISP's router? How can we route all of our public IP's to the outside interface(198.24.210.226)?
This works other networks that are like whole network with /29 mask and have router in front of ASA using bridge. But in my case i just have DSL modem bridged in front of ASA. This static nat works like should if i use like Zywall USG series fw and this same configuration works in my customers, but they have those scenarios i said having mask /29 and router in front...
It seems that the problem is in ASA, like i won't show those public IP:s to public router from my operator. Because if i roll those other public IP:s on my ASA:s outside interface: i will use 83.x.x.25 and 83.x.x.41 on outside interface and after that put back my original 83.x.x.10 then my static nat is working just fine, atleast few hours, but not in next morning because ISP router flushes ARP cache.
I have ASA 5520 with Version 8.2(5), the ISP give me a block of IP pubic (201.148.156.193/28), one IP valid (201.148.156.194) have the Global NAT (all users LAN) and server FTP, but i need that IP 201.148.156.195 is used for VCSe, and the IP 201.148.156.196 is used for other server FTP.
I am configuring this new router for a client. I am running into an issue that I cannot get working. They use 5 public IP addresses. Currently the wan port on the router is .66 and I have all the ports forwarded to the correct internal IPs. This works fine. However I need to forward parts from other public IPs (ex: .67) to internal IPs. So far I have been able to accomplish this via the One to One NAT feature. It allows me to forward ONE port from a public IP to a private IP. However I need to forward 3 or 4 ports per public IP to a single internal address. Does this router not support that functionality?
Attached is my updated ASA 5505 (8.4[2]) config. With this config, basically the "laptop" group works fine, but the leo and orion groups don't ever receive packets inbound. No DNS, nothing.
The laptop is windows, the other two are servers with two NICs. The interface cards are Intel Pro/1000s. I've been through everything including Vlan protocol conflicts and actually enabled the servers for 802.1(Q).
If there are any small business routers that offer one-to-one NAT? I have several public IP addresses assigned to me by CenturyLink. I have two servers that provide email and web hosting for two different domains. I want to put the client machines on one VLAN (VLAN Z) and assign it a public IP address (to keep server traffic separate). I want to put each server on its own VLAN (VLANs X & Y) and assign each server its own public IP address. I need the router to be able to provide a firewall and port forwarding for each VLAN. I also need to be able to route traffic between VLANs so the clients on VLAN Z can access their email and the websites on VLANs X and Y. I also need to be able to route DNS traffic between VLANs so each server can provide name resolution for their respective domains.
So, is this possible with a small business router or do I need to look at something different? I'm fairly certain this configuration is not possible with my current Cisco RVS4000. What it boils down to is I need a router that is capable of having multiple public IP addresses on the same interface and to forward those public addresses to private VLAN subnets. This would be one-to-one NAT if I understand it correctly..
The client has a Cisco RVS4000. There are 3 Internet devices need to be accessed from the outside and will use one public IP for one device. I don't see any options to setup on Cisco RVS4000 to do 3 NATs. If Cisco RVS4000 doesn't work in this situation, which router will do?
I have a Netgear ProSafe VPN Firewall FVX538. But I also have 10 Public IP Addresses that I will like to setup for three web services. So how do I set this up. With multiple routers. Or can my Netgear FVX538 take multiple Public IP Addresses to the same ports. If not how can setup multiple routers. one being the main one.
I have a customer that has an RSV4000 Router. The customer has also purchased a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses to printers either by configuring a static IP on each printer directly or thru IP mapping or some other method. Does the RSV4000 support using multiple public IP addresses and if so what configuration is needed in the router for the printers to be seen by the outside world.
I'm currently replacing my ASA 5505 with a 5510. I have a range of public IP addresses, one has been assigned to the outside interface by the setup wizard (e.g. 123.123.123.124 ) and another I would like to NAT to an internal server (e.g 192.168.0.3 > 123.123.123.125). On my asa 5505 this seemed fairly straigh forward, i.e. create an incoming access rule that allowed SMTP to 123.123.123.125 and then create a static nat to translate 192.168.0.3 to 123.123.123.125. Since I've tried to do the same on the 5510 traffic is not passing through so I'm assuming that the use of additional public IP addresses is not handled in the same way as the 5505? I also see that by default on the 5505, 2 VLANs are created, one for the inside and one for the outside, where as this is not the case on the 5510. Is the problem that VLANs or sub-interfaces need to be created first? I'm doing the config via ASDM.
Everything else seems to OK i.e. access to ASDM via 123.123.123.124, outbound PAT and the site-to-site VPN.
I'm stuck at asa 5505 nat, port forwarding configuration Here is what i need:
host1: 192.168.1.1 service tcp/100 >>>>> public ip 1.1.1.1 service tcp/100 host2: 192.168.1.2 service tcp/200 >>>>> public ip 1.1.1.1 service tcp/200 host3: 192.168.1.3 service tcp/300 >>>>> public ip 1.1.1.1 service tcp/300
So people from remote just need to use 1.1.1.1 public ip to access all the ports on three different inside server.I can do this on my old ASA 5505 with 8.0(4). Looks like there're lots of change from 8.0 to 8.4.
home router is a wrt160n v3 With my iPad I set up the built in IPSec VPN to my office's cisco gateway. I successfully get the VPN logo. With an RDP app, i can access my work network from multiple public locations from my iPad. At home, on my laptop, I start the cisco client then use the windows rdp, presto i'm in my work network. At home on my iPad I can activate the VPN, but I can not connect with rdp. I spoke with linksys support tonight they had me add port 3389 to port range triggering and disable the firewall on the home router. This didn't solve the problem. To recap: 1) I can connect to my work network with rdp from multiple public locations, but not at home with the iPad 2) I can connect to my work network at home with my laptop with the cisco client ant the windows rdp
I have this motorola sbv5121e modem. I can connect one PC to it directly. When I try to connect a secont PC, via a switch, it won't give out 2 IP addresses. Moreover, I see that the one IP address it does give out, is a public one (like 22.x.x.x). I'm on XP and show the addresses with ipconfig. Is this modem defective hardware-wise, or is some setting internally wrong? How can I see what the DHCP server does?
We will acquire a DSL connection with 5 static public address. How can I use the 5 static public address using a linksys router. Is it depends with linksys router model?
I have a public IP and I want to be able to view my three systems connected to a linksys router from the internet. How can configure the router to see three systems with just one Public IP address whenever I am on the internet?
I have a ASA5505 that I need to allow IPSEC and SSL VPNs through. The ASA is connecting to a BT Business ADSL router, what address should I be using on the ASA outside interface that will allow the ASA to be reachable from the Internet?
I'm planning to set up a network with two routers and one cable connection. One router will be for public wifi at my business and the other will be for my Point of sale system and private use. I think I have it figured out but want to double check the set up. Someone tell me if this isn't correct or if there's a better way of doing it.Cable modem --> connect via ethernet to Router #1 WAN port. Router #1 Lan port 1: connect via ethernet to router #2 WAN. Now, router 1 and 2 will have two different subnets; 192.168.1.x and 192.168.2.x respectively. Router #2 is the one that I should use for my private network and for the POS system since it can't be accessed by users from router #1 correct? I have DD-WRT installed on both routers but I plan on putting Tomato firmware for router #1 to limit bandwidth for public wifi and keep DD-WRT installed for router #2.
